ANSWER

[tex]\cos( \angle \: F) = \frac{5}{13}[/tex]

EXPLANATION

The side length adjacent to <F is 5 units.

The length of the hypotenuse is 13 units.

The cosine ratio is

[tex] \cos( \angle \: F) = \frac{adjacent}{hypotenuse} [/tex]

This implies that:

[tex] \cos( \angle \: F) = \frac{5}{13}[/tex]

The fourth choice is correct.

you need to find the mean on these numbers that is step one in finding standard deviation. so this is 44.2. now you need to subtract the mean from each number and square the result. after that step you now have these numbers.... 3.24, 139.24, .64, .4,.64,282.24,116.64,77.44,27.04. now the next step is to find the mean of these numbers. you get 71.9 appx.. now all you do is square root this number you get 8.5 when you round to the nearest thenth

Answer:

135

Step-by-step explanation:

Angles 1 and 3 are vertical angles, so they are congruent.

Since angle 1 measures 135 deg, angle 3 also measures 135 deg.

Angles 3 and 7 are corresponding angles of parallel lines cut by a transversal, so they are congruent.

Since angle 3 measures 135 deg, angle 7 also measures 135 deg.

Answer: m<7 = 135 deg

congruence, in mathematics, the term employed in several senses, each connoting harmonious relation, or agreement, and correspondence. so 2 triangles are congruent if 2 sides and their included angle in the 1 are = to 2 sides and their included angle in the other.

Angles one and three are vertical angles, so they are congruent.

Since angle one measures 135 degree, angle three also measures 135 degree.

Angles 3 or 7 are corresponding angles to the parallel lines cut by the transversal, so they are congruent.

Since angle 3 measures 135 deg, angle 7 also measures 135 deg.

Answer:

No. The ladder is too steep.

Step-by-step explanation:

Length of ladder = 17 feet.  This is the hypotenuse.

Side a of a right triangle = 16.6

To answer this, you need one of the trigonometric functions.  

Opposite = 16.5

hypotenuse = 17

The function you need is the sine function.

Sin(theta) = opposite / hypotenuse

sin(theta) = 16.5 / 17

Sin(theta) = 0.97059

theta = sin-1(0.07059)

theta = 76.07

No the ladder is too steep.

Answer:

The ladder will not be safe.

Step-by-step explanation:

The ladder is 17 ft long

The top of the ladder is 16.5 ft above the ground

The ladder makes a right triangle of height = 16.5 ft and hypotenuse = 17 ft

To find the angle the ladder makes with the ground,

Height ÷ hypotenuse = sin angle

i.e [tex]\frac{16.5}{17}[/tex] = sin angle

[tex]sin^{-1}[/tex] angle = 76.1°

So the ladder is not safe since the angle it makes with the ground is greater than 70°.

Answer:

y=6x-2

Step-by-step explanation:

to find the 6 you have to see the difference in the y values and the y values are going up by 6 each time. the -2 comes from the y intercept. to find the y intercept you have to see when x=0 which in this table is -2

hope i helped

y = 6x - 2. The equation that describes how x and y are related is given by y = 6x - 2.

If we look the table of the image, we can see that the graph that describes the relation between x and y is a straight line.

The set of infinite points aligned in the same direction is known as straight line and its main equation has the form y = mx + b, where m is the slope, and b the y-intercept.

In order to solve this problem, we need to find the slope which is [tex]m = \frac{y_{2}-y_{1} }{x_{2}- x_{1}}[/tex]

Solving m for two points of the straight line, Let's take (0, -2) and (1, 4):

[tex]m = \frac{4-(-2)}{1 - (0)}=\frac{6}{1} \\m = 6[/tex]

We can see if we take two points in order from the table always obtain the value m = 6, which means for each unit of x, y increase 6 units.

To find the y- intercept (0, y), from the table of the image we can see when x = 0, y = -2.

Writing the equation y = mx + b, with m = 6 and b = -2:

y = 6x -2

Answer:

3 1/4

Step-by-step explanation:

I'll assume you meant 3/4 + (1/3 / 1/6) - (- 1/2) and not 3/4 + (1/3 \ 1/6) - (- 1/2)

So we start with 3/4 + (1/3 / 1/6) - (- 1/2)

The toughest part is (1/3 / 1/6) , but remember that when dividing with a fraction, it's like multiplying by the inverse of that fraction, so...

[tex]\frac{1/3}{1/6} = \frac{1}{3} * \frac{6}{1} = \frac{6}{3} = 2[/tex]

Then we return to the original problem with the new value for the parenthesis:

3/4 + 2 + 1/2 = 3/4 + 8/4 + 2/4 = 13/4 or 3 1/4

Answer:

The correct answer is 3 1/4

Step-by-step explanation:

It is given that,

3/4 + (1/3 \ 1/6) - (- 1/2)

To find the value of given expression

3/4 + (1/3 \ 1/6) - (- 1/2) for finding the answer we have to find the value of

(1/3 / 1/6) = 1/3 * 6/1 = 2

3/4 + (1/3 \ 1/6) - (- 1/2 = 3/4 + 2 + 1/2

 = 3/4 + 8/4 + 2/4 = (3 + 8 + 2)/4 = 13/4 = 3 1/4

The correct answer is 3 1/4

Answer:

  105

Step-by-step explanation:

The numbers that can be used to form triangles are collectively called "triangle numbers." The n-th triangle number is the sum of all numbers less than or equal to n. It is ...

  n(n+1)/2

For n=14, the number is 14(15)/2 = 7·15 = 105.

The clerk used 105 oranges to make the arrangement.

The grocery clerk used 105 oranges to set up a triangular display. This is calculated with the formula for triangular numbers sequence (n*(n+1))/2 where n is the base of the triangle.

To solve the problem, we need to use the approach for calculating the number of items in a triangular number sequence. Triangular numbers are used to form equilateral triangles. The nth term of a triangular number sequence is given by the formula (n*(n+1))/2. In this case, the base of the triangle contains 14 oranges, so n=14.

Using the formula, the total number of oranges used to form triangle by the grocery clerk is (14*(14+1))/2 = 105 oranges. So, the clerk used 105 oranges to set up the display.

Answer:

x=12.5

Step-by-step explanation:

The given triangle is a right angle triangle.

We cannot use the Pythagoras theorem as the lengths of all sides are not known. We will use triangular ratios here to solve the given problem.  

As it is clear from the diagram that x is the hypotenuse of the triangle and 11 is the length of the base. We will use a ratio in which base and hypotenuse are used.

So,

cos ⁡θ= base/hypotenuse

cos⁡ 28=11/x

x=11/cos⁡28  

x=11/0.8829

x=12.45

Rounding off to nearest 10

x=12.5

In every right triangle, a leg is given by the multiplication between the hypothenuse and the sine of the opposite angle, or the cosine of the adjacent one.

So, in this case, we have

[tex]11 = x\cos(28)[/tex]

Solving for x, we have

[tex]x = \dfrac{11}{\cos(28)}\approx 12.5[/tex]

Answer:

x= -1, 5.4

Step-by-step explanation:

[tex]f(x)= x^2-x-12[/tex]

[tex]g(x)= 3.4x -6.6[/tex]

f(x) is a quadratic equation and g(x) is a linear equation

To find f(x)= g(x) we need to find the point where the graph  of f(x) and g(x) intersects.

The quadratic equation f(x) and linear equation g(X) intersects at two points

from the graph f(x)= g(x) at x= -1 and x=5.4

Answer:

You take the repeating group of digits and divide it by the same number of digits but formed only by 9s.

Step-by-step explanation:

Let's say you have 0.111111111111...., your repeating pattern is 1, that consists of one digit (1).  You take that digit and you divide it by 9:

1/9 is the fraction equivalent to 0.111111111111111...

Let's say you have 0.12121212121212...., the repeating pattern is 12, that consists of 2 digits (12).  You take those 2 digits and divide them by 99:

12/99 is the fraction equivalent to 0.12121212121212...

which can be reduced to 4/33

If you have 0.363363363363..., your repeating pattern is 363, which is 3 digits, so you divide 363by 999:

363/999 is the fraction equivalent to  0.363363363363...

which can be simplified to 121/333

To write a repeating decimal as a fraction, multiply the decimal by a suitable power of 10 to eliminate the repeating part, subtract the original equation from the new equation, solve for the variable, and simplify the fraction if possible.

To write a repeating decimal as a fraction, you can use a trick that involves using a variable to represent the repeating part of the decimal. Let's take an example of the repeating decimal 0.3333...

Therefore, the repeating decimal 0.3333... can be written as the fraction 1/3. This method can be applied to any repeating decimal to convert it into a fraction.

Answer:

Option B is correct.

Step-by-step explanation:

A city has population = 10000

Population increase each year = 4%

So, Population increase after 1 year = 10000 * 4%

                                                           = 10000*4/100

                                                           = 400

Adding in the current population:

10000+400 = 10,400

Population increase after 2 year = 10,400*4%

                                                     = 10400*4/100

                                                      = 416

Adding in the current population:

10400+416 = 10816

Population increase after 3 year = 10,816*4%

                                                     = 10816*4/100

                                                      = 433

Adding in the current population:

10816+433 = 11,249

Population increase after 4 year = 11,249*4%

                                                     = 11249*4/100

                                                      = 450

Adding in the current population:

11249+450 = 11,699

Population increase after 5 year = 11,699*4%

                                                     = 11699*4/100

                                                      = 468

Adding in the current population:

11699+468 = 12167

So, the population after 5 yeras will be 12167.

Option B is correct.

The population of the city will be approximately 12,167 people after 5 years, calculated by using the formula for exponential growth with a 4% annual increase from the initial population of 10,000.

The question involves calculating the future population of a city that is experiencing exponential growth over a period of time. To find the population of a city 5 years later when the population increases by 4% per year, we use the formula for exponential growth, which is:

P = [tex]P0 * (1 + r)^t[/tex]

Where:

P is the future population

P0 is the initial population (which is 10,000)

r is the annual growth rate (which is 4% or 0.04)

t is the number of years (which is 5)

Using the formula, we calculate:

P = 10,000 × (1 + 0.04)⁵

P = 10,000 × (1.04)⁵

P = 10,000 × 1.2166529

P = 12,166.529

So, the population will be approximately 12,167 people 5 years later.

To divide the expression (14x^2 - 21x) by (2x - 3), you can use long division to get the answer 7x.

To divide the expression (14x^2 - 21x) by (2x - 3), we can use long division. Here are the steps:

Therefore, the answer is 7x.

The polynomial f(x)=x^4+3x^2+7 has four roots over the complex numbers according to the fundamental theorem of algebra, counting roots with multiplicity greater than one as distinct. This is consistent with the theorem's stipulation that a polynomial of degree n has exactly n roots.

The subject of this question is the fundamental theorem of algebra which belongs to the domain of Mathematics, specifically the study of polynomials. As indicated in the question, we have a function, f(x), which represents a polynomial of degree 4 as shown by the highest exponent. According to the fundamental theorem of algebra, a polynomial of degree n has exactly n roots, counting multiplicity. This means a function f(x)=x4+3x2+7, which is a fourth degree polynomial, will have four roots over the complex numbers.

This is also true per the theorem when roots with multiplicity greater than one are considered distinct. For example, f(x)=x2 is a polynomial of degree 2; it has two roots, both are zero, hence the two roots are counted as two distinct roots.

While the quadratic formula is used for finding roots of second degree polynomials, it is not directly applicable here since we are dealing with a fourth degree polynomial.

From the diagram, the horizontal distance traveled is x meters.

This is the side adjacent to the 6° angle.

Since we know the hypotenuse to be 170m, we use the cosine ratio to find the value of x.

[tex]\cos(6 \degree) = \frac{opposite}{hypotenuse} [/tex]

[tex] \cos(6 \degree) = \frac{x}{170} [/tex]

.

This implies that

x=170cos(6°)

x=169.0687222

To the nearest tenth, the horizontal disance travelled is 169.1m

Answer:

Step-by-step explanation:

She has already travelled 45 miles so there's another 393-45 = 348 miles to travel. So  if she continues at 58 mph she will take 348 / 58 = 6 hours.

Answer:

Step-by-step explanation:

This is right triangle trig.  The reference angle is 12 in one case and 60 in the other, but the horizontal distance doesn't change in either one, and neither does what you are looking for, which is the height of the balloon in both cases of the angle differences.  And if you're looking for the difference in the height, you'll find both and subtract the smaller from the larger.  

The height is across from the reference angle and the horizontal distance is adjacent to the reference angle, so the trig identity you want is tangent.  Set up according to the angle measure of 12 degrees:

[tex]tan(12)=\frac{x}{280}[/tex] and

280 tan(12) = x

x = 59.5 ft

Now for the angle measuring 60 degrees:

[tex]tan(60)=\frac{x}{280}[/tex] and

280 tan(60) = x

x = 484.9

The difference between the two heights is 425.5 feet.
