Step-by-step explanation:

There are several different ways you can work problems like this. The method you may prefer may be different from the one I prefer. At least, they include ...

You can treat the smaller units as a fraction of the larger unit: 23 7/12 -13 11/12. Then subtracting mixed numbers proceeds in any of the usual ways. You may even be able to use a calculator for this.You can "subtract by adding": 8 inches added to the subtrahend makes it 14 ft 7 in; then adding 9 ft makes it 23 ft 7 in. The difference is then seen to be 9 ft 8 in.You can subtract the different units separately, then "make change" or "borrow" as required. 23'7" -13'11" = 10'(-4)" = 9'8". (This is probably the method I prefer.) An on-line calculator may be able to handle the mixed units to your satisfaction (see attached).

1) The sum of the lengths of two opposite sides of the circumscribed quadrilateral is 12 cm, the length of a radius of the circle is 2 cm. Find the area of the quadrilateral.

2) A quadrilateral is circumscribed around a circle. The sum of the lengths of two of its opposite sides is 15 cm. Find the perimeter of the quadrilateral.

Answers

Answer:

24cm and 225cm

Step-by-step explanation:

Answer:

1) [tex]24cm^2[/tex]

2) [tex]30cm[/tex]

Step-by-step explanation:

1) Remember that: The area of a quadrilateral circumscribed about a circle equals  semi-perimeter (half the product of the perimeter of the quadrilateral) and the radius of the circle.  

By the other hand in a quadrilateral circumscribed the sum of the measures of any pair of two opposite sides is equal to the sum of the measures of the other pair of the opposite sides.

Then you know that the sum of all sides should be 12cm+12cm=24cm

Area= Semi-perimeter*r

where

Semi-perimeter= perimeter/2= sum of all sides/2

r= radius of the circle

Then:

[tex]Area=(24cm/2)*(2cm)= 24cm^2[/tex]

2) Perimeter= sum of all sides

And as the sum of the measures of any pair of two opposite sides is equal to the sum of the measures of the other pair of the opposite sides.

Perimeter=15cm+15cm=30cm

For a us census clock based on the 2000 census, the birth light would flash every 10 seconds, the death light every 16 seconds, the immigration light every 81 seconds, and the emigration light every 900 seconds, to indicate gains and losses in population.

A. If the birth and death lights flashed at the same time, how many seconds would pass before they flashed together again?

Show work

Answers

Answer:80

Step-by-step explanation:

Let's pretend we start a stopwatch when the birth and death light flash together.  The birth light will flash at 10 seconds, 20 seconds, 30 seconds, etc.  The death light will flash at 16 seconds, 32 seconds, 48 seconds, etc.

So the trick here is to find the least common multiple (LCM) of 10 and 16.  To do that, we write the prime factorization of each:

10 = 2×5

16 = 2⁴

The LCM must include all these prime factors without any duplicates.  So the LCM = 2⁴×5 = 80.  We can check our answer by dividing:

80 / 10 = 8

80 / 16 = 5

So 80 is indeed a multiple of both 10 and 16.

By using the concept of HCF and LCM, the result obtained is

The birth and death light will flash again after 80 seconds.

What is HCF and LCM of two numbers?

HCF means Highest Common Factors. HCF of two numbers a and b is the highest number which divides both a and b

LCM means Lowest Common multiple. LCM of two numbers a and b is the lowest numbers which is divisible by both a and b

HCF and LCM can be calculated by division method and prime factorization method.

Also there is an important formula relating HCF and LCM

HCF [tex]\times[/tex] LCM = Product of two numbers

Here,

The birth light would flash every 10 seconds,

The death light every 16 seconds,

The immigration light every 81 seconds,

The emigration light every 900 seconds,

They will flash again after LCM (10, 16)

Now,

10 = [tex]2 \times 5[/tex]

16 = [tex]2 \times 2 \times 2 \times 2[/tex]

LCM of 10 and 16 = [tex]2 \times 2 \times 2 \times 2 \times 5[/tex] = 80

The birth and death light will flash again after 80 seconds.

A flagpole stands in the middle of a flat, level field. 50 feet away from its base, a surveyor measures the angle to the top of the flagpole as 48 degrees. How tall is the flagpole? Round to the nearest hundredth of a foot

Answers

Answer:

55.53 feet.

Step-by-step explanation:

We have been given that a flagpole stands in the middle of a flat, level field. 50 feet away from its base, a surveyor measures the angle to the top of the flagpole as 48 degrees.

We can see from attached photo that flagpole, the surveyor forms a right triangle with respect to ground.    

[tex]\text{tan}=\frac{\text{Opposite}}{\text{Adjacent}}[/tex]

[tex]\text{tan}(48^{\circ})=\frac{h}{50}[/tex]

[tex]\text{tan}(48^{\circ})*50=\frac{h}{50}*50[/tex]

[tex]1.110612514829*50=h[/tex]

[tex]h=1.110612514829*50[/tex]

[tex]h=55.53062574[/tex]

[tex]h\approx 55.53[/tex]

Therefore, the height of the flagpole is approximately 55.53 feet.

What is the length of the shortest side of a triangle that has vertices at (-6, -5), (-5, 6), and (-2, 2)? A. B. C. D.

Answers

Answer:

5

Step-by-step explanation:

We can use the distance formula with 3 different vertices to figure out the shortest of the three sides.

The distance formula is [tex]\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]

Where (x_1,y_1) is the first points and (x_2,y_2) is the second set of points, respectively.

Now let's figure out the length of 3 sides.

1. The length between (-6,-5) & (-5,6):

[tex]\sqrt{(y_2-y_1)^2+(x_2-x_1)^2} \\=\sqrt{(6--5)^2+(-5--6)^2}\\ =\sqrt{(6+5)^2+(-5+6)^2} \\=\sqrt{11^2+1^2} \\=\sqrt{122}[/tex]

2. The length between (-6,-5) & (-2,2):

[tex]\sqrt{(y_2-y_1)^2+(x_2-x_1)^2} \\=\sqrt{(2--5)^2+(-2--6)^2} \\=\sqrt{(2+5)^2+(-2+6)^2}\\ =\sqrt{7^2+4^2}\\ =\sqrt{65}[/tex]

3. The length between (-5,6) & (-2,2):

[tex]\sqrt{(y_2-y_1)^2+(x_2-x_1)^2} \\=\sqrt{(2-6)^2+(-2--5})^2}\\ =\sqrt{(-4)^2+(3)^2} \\=\sqrt{25} \\=5[/tex]

Thus, length of the shortest side is 5.

Answer:

5 units

Step-by-step explanation:

Draw the triangle with the vertices given. Identify the smallest side and draw in a right triangle using the smallest side of the original triangle as the hypotenuse of the right triangle, as shown on the grids below.

The horizontal side of the small right triangle measures 3 units and the vertical side of the small right triangle measures 4 units.

Use the Pythagorean theorem to find the length of the hypotenuse.

Therefore, the length of the shortest side of the triangle measures 5 units.

3^2 + 4^2  =  c^2

9 + 16  =  c^2

25  =  c^2

George is 12 years older than Jeannie the sum of their ages in 5 years will be 50 how old is Jennie now

Answers

Answer:

14 years old

Explanation:

Use this system of equations if G=George and J=Jeannie:

G-12=J

50=(G+5)+(J+5)

So, change second equation becomes

40-G=J

Then use substitution:

G-12=40-G

2G=52

G=26

Then, to find Jeannie’s age, go back to one of the equations and substitute G.

26-12=J

So, J=14

Jeannie is currently 14 years old.

To solve any questions relating to ages, I find it easier to make a table, like in the picture below.

See picture for answer and clear diagram.

-----------------------------------------------------------------

Notes/Explanations + answer in written form

Jennies age now = x

So Georges age now would be: x + 12   (since he is 12 years older)

Jennies age in 5 years would be: x + 5   (since it is 5 years later)

Georges age in 5 years would be: x + 12 + 5 = x + 17

We are told that their ages in 5 years would add up to 50. So we can write an equation like so:

x + 17   +   x + 5 = 50                 (All you have to do now is solve it)

2x + 22 = 50                             (combine like terms)

2x = 28                                      (subtract 22 from both sides)

x = 14                                         (divide both sides by two)

That means that Jennies age is 14 years

Aleksandra Tomich invested $9,102 and part at 8% simple interest and part 4% simple interest for a period of 1 year. How much did she invest at each rate if each account earned the same interest?


Please Help ​

Answers

Answer:

$3034 at 8%$6068 at 4%

Step-by-step explanation:

The ratio of interest rates is 8% : 4% = 2 : 1. Since the amount of interest earned in each account is the same, the ratio of amounts invested will be the inverse of that, 1/2 : 1/1 = 1 : 2.

Then 1/(1+2) = 1/3 of the money is invested in the 8% account. That amount is ...

  $9102/3 = $3034 . . . . invested at 8%

The remaining amount is invested at 4%:

  $9102 - 3034 = $6068 . . . . invested at 4%

_____

The interest earned in 1 year in each account is

  0.08·$3034 = 0.04·$6068 = $242.72

_____

If you really need an equation, you can let x represent the amount invested at the higher rate. (Using this variable assignment avoids negative numbers later.) Then 9102-x is the amount invested at the lower rate.

  0.08x = 0.04(9102-x)

  0.12x = 0.04·9102 . . . . . eliminate parentheses, add 0.04x

  x = (0.04/0.12)·9102 = 9102/3 . . . . . divide by the coefficient of x. Same answer as above.

Find the value of b in the graph of y=3x+b if it is known that the graph goes through the point: O(3,8)

Answers

Answer:

b= -1

Step-by-step explanation:

y=3x+b

8= 3(3)+b

b= -1

The value of b in the equation y = 3x + b that passes through (3, 8) is -1

From the question, we have the following parameters that can be used in our computation:

The equation of the graph

Where, we have

y = 3x + b

Also, we have the point

(3, 8)

This means that

x = 3 and y = 8

When these values are substituted into the equation, we have

8 = 3 * 3 + b

This gives

8 = 9 + b

Evaluate the like terms

b = -1

Hence, the value of b is -1

f(x) = x2 – 3x – 2 is shifted 4 units right. The result is g(x). What is g(x)?

Answers

Answer:

g(x) = x^2 - 11x + 26

Step-by-step explanation:

In translation of functions, adding a constant to the domain values (x) of a function will move the graph to the left, while subtracting from the input of the function will move the graph to the right.

Given the function;

f(x) = x2 - 3x - 2

a shift 4 units to the right implies that we shall be subtracting the constant 4 from the x values of the function;

g(x) = f(x-4)

g(x) = (x - 4)^2 - 3(x - 4) -2

g(x) = x^2 - 8x + 16 - 3x + 12 - 2

g(x) = x^2 - 11x + 26

Answers

Question 1:

For this case we have that by definition, the GCF of two numbers is the largest number that is a factor of both numbers. For example, the number 10 is the biggest factor that 50 and 30 have in common.

We must find the GCF of the following expression:

[tex]30t ^ 2u + 12tu ^ 2 + 24tu[/tex]

We look for the prime factorization of each number:

[tex]30: 2 * 3 * 5\\12: 2 * 2 * 3\\24: 2 * 2 * 2 * 3[/tex]

The GCF of the three numbers is [tex]2 * 3 = 6[/tex]

So:

[tex]6tu (5t + 2u + 4)[/tex]

Answer:

Option C

Question 2:

For this case we have that by definition of power properties of the same base, that:

[tex]a ^ n * a ^ m = a ^ {n + m}[/tex]

That is, for multiplication of powers of the same base, the same base is placed and the exponents are added.

So:

[tex]b ^ n * b ^ m = b ^ {n + m}[/tex]

ANswer:

[tex]b ^ {n + m}[/tex]

Option A

The greatest common factor of the expression is 6tu, and the factored form is 6tu(5t + 2u + 4), . For the property of exponents, the rule is that when multiplying powers with the same base, you add the exponents, yielding an answer of  b^n+m.

15.The correct option is (C) and 16.The correct option is (A).

To solve the problem factor out the greatest common factor from the expression 30t2u + 12tu2 + 24tu, we have to look for the highest power of each variable and the largest number that can divide each term. The greatest common factor for this expression is 6tu.

Factoring out 6tu gives us:

Divide each term by 6tu:30t2u / 6tu = 5t12tu2 / 6tu = 2u24tu / 6tu = 4Write the factored expression as 6tu(5t + 2u + 4).

The correct answer is C. 6tu(5t + 2u + 4).

For the property of exponents problem, when multiplying powers with the same base, you add the exponents. So, bn · bm = bn+m.

The correct answer is A. bn+m.

2. b. Mark’s average < Jay’s average

Step-by-step explanation:

1. What is Mark’s slugging average?

The slugging average gives more weight to the multi-base hits (compared to single-base hits) in opposition with the batting average.

So, a single hit is worth 1 point, a double is worth 2 points, a triple 3 points and a homerun is worth 4 points.  It's a weighted average calculation.

Mark had 25 singles, 10 doubles, 3 triples and 10 homeruns during 140 presences 140 at bat.

25(1) + 10(2) + 3(3) + 10(4) = 94/140 = .671

2. How does Mark's average compares to Jay's?

Let's first calculate Jay's slugging average then we'll be able to decide.

Jay had 10 singles, 6 doubles, 5 triples and 14 homeruns in 90 presences.

10 (1) + 6 (2) + 5 (3) + 14 (4) = 10+12+15+56 = 93 / 90 = 1.033

We can definitely say that Mark's slugging average (0.671) calculated above is lower than Jay's average (1.033).  So,

b. Mark’s average < Jay’s average

Whats the answer

Answers

Answer:

1/2

Step-by-step explanation:

sin(K)=5/10=1/2

Final answer:

The sine function in mathematics relates angles of a right triangle to the ratios of its side lengths. The value of sin(K) depends on the value of angle K, measured in radians.

Explanation:

In mathematics, the sine function is a trigonometric function that relates the angles of a right triangle to the ratios of the side lengths. The value of sin(K) depends on the value of angle K, which is measured in radians.

For example, if K = π/2, then sin(K) = 1. If K = 0, then sin(K) = 0.

To find the value of sin(K), you can use a calculator or reference table that provides the values of sine for different angles.

Find the volume of the solid obtained by rotating the region bounded by the given curves about the specified axis. y=0 , y=cos (7x) , x=π/14 , x=0 about the axis x=3

Answers

Answer:

π/49·(44 -π)

Step-by-step explanation:

Using the "shell" method, a differential of volume is the product of the area of a cylindrical shell and its circumference around the axis of rotation. Here, that area is ...

dA = y·dx = cos(7x)dx

The radius will be the difference between x and the axis of rotation, x=3, so is ...

r = 3 -x

Then the differential of volume is ...

dV = 2πr·dA = 2π(3-x)cos(7x)dx

The volume will be the integral of this over the limits x ∈ [0, π/14].

∫dV = 6π·∫cos(7x)dx -2π·∫x·cos(7x)dx . . . from 0 to π/14

= (6/7)π·sin(7x) -(2/49)π·(cos(7x) +7x·sin(7x)) . . . from 0 to π/14

= (6/7)π(1 -0) -(2/49)π((0 -1) +(π/2-0))

= π(42/49 +2/49 -π/49)

= (π/49)(44 -π) . . . . cubic units . . . . . approx 2.61960 cubic units

Final answer:

The volume of the solid created by rotating the bounded region about the axis x=3 is found using cylindrical shells and evaluating the integral from x=0 to x=π/14 of the expression 2π(3-x)cos(7x)dx.

Explanation:

To find the volume of the solid obtained by rotating the region bounded by the curves y=0, y=cos(7x), x=π/14, and x=0 about the axis x=3, we need to use the method of cylindrical shells.

For a small strip at position x with height y and thickness dx, rotating around x=3 creates a cylindrical shell with circumference 2π(3-x), height cos(7x), and thickness dx.

The volume of each shell is V = 2π(3-x)cos(7x)dx, and summing these from x=0 to x=π/14 gives us the total volume.

So, the volume V is the integral:

∫0π/14 2π(3-x)cos(7x)dx.

This volume is found by evaluating the definite integral.

a rectangle is 6 units "wide" and x -8 use long it has the same area of a triangle with a height of 7 units and a base of x minus 3 years what is the area of the rectangle

Answers

Answer:

  42 square units

Step-by-step explanation:

The area of the rectangle is the product of its length and width:

  area = 6(x -8)

The area of the triangle is half the product of its base and height:

  area = (1/2)(x-3)·7

These two areas are equal, so we have ...

  6(x -8) = (1/2)(x -3)(7)

  6x -48 = 3.5x -10.5 . . . . eliminate parentheses

What effect does changing the function f(x)=2sin(x/2)−1 to the function g(x)=2sin(x)−5 have on the graph of f(x)?

Answers

Final answer:

Changing the function f(x)=2sin(x/2)-1 to the function g(x)=2sin(x)-5 shifts the graph of f(x) downward by 4 units and changes the period from 4π to 2π.

Explanation:

Changing the function f(x)=2sin(x/2)-1 to the function g(x)=2sin(x)-5 has the effect of shifting the graph of f(x) downward by 4 units and changing the period of the graph from 4π to 2π.

By comparing the two functions, we can see that the constant -1 in f(x) has changed to -5 in g(x), resulting in a downward shift of 4 units. The factor of 1/2 in the argument of the sine function in f(x) has been removed in g(x), which changes the period from 4π to 2π.

Overall, the graph of f(x) has been shifted downward and compressed horizontally to form the graph of g(x).

Consider the following. f(x) = x5 − x3 + 6, −1 ≤ x ≤ 1 (a) Use a graph to find the absolute maximum and minimum values of the function to two decimal places. maximum minimum (b) Use calculus to find the exact maximum and minimum values. maximum minimum

Answers

Final answer:

To find the absolute maximum and minimum values of the function f(x) = x^5 - x^3 + 6, we can use both a graphical approach and a calculus approach. The graphical approach involves plotting the function and identifying the highest and lowest points on the graph. The calculus approach involves taking the derivative of the function, finding critical points, and evaluating the second derivative to determine whether the critical points are maximum or minimum values.

Explanation:Graphical approach:


To find the absolute maximum and minimum values of the function, we need to graph it within the given interval and identify the highest and lowest points. By plotting the function and examining the graph, we can see that the absolute maximum value is approximately 6.66 at x ≈ 1, and the absolute minimum value is approximately 5.33 at x ≈ -1.

Calculus approach:


To find the exact maximum and minimum values, we need to use calculus. We take the derivative of the function f(x) = x^5 - x^3 + 6, which is f'(x) = 5x^4 - 3x^2. Setting f'(x) = 0 and solving for x, we find that x = 0 is a critical point. To determine whether it is a maximum or minimum, we take the second derivative f''(x) = 20x^3 - 6x and evaluate it at x = 0. Since f''(0) > 0, x = 0 is a relative minimum. Plugging x values outside the given interval into the function, we find that f(-1) ≈ 5.33 is the exact minimum value, and f(1) ≈ 6.66 is the exact maximum value.
