Can someone please help me with this question please. ​

Answer:

Step-by-step explanation:

A = x² - 5x - 14

Factor using AC method.  Here, a = 1, b = -5, and c = -14.

ac = 1×-14 = -14

Factors of -14 that add up to -5 are -7 and 2.

A = (x - 7)(x + 2)

So the dimensions are x-7 and x+2.

The dimensions of the rectangle represented by the quadratic equation x² - 5x - 14 could be 7 and -2, but in a physical context we only consider the positive value 7.

The area of a rectangle is given by multiplying its length and width. In this case, the area is expressed as a quadratic equation, x² - 5x - 14 = 0. Quadratic equations typically represent parabolas when graphed on a two-dimensional plot, but in this case, we're looking for linear dimensions of a rectangle. To find the dimensions of the rectangle, we need to factor this equation.

The factors of this quadratic equation are (x - 7) and (x + 2). Therefore, the two dimensions of the rectangle could be 7 and -2. However, in real-world scenarios, dimensions are often positive values due to physical constraints (you can't have a rectangle with negative length or width). So, normally, we would only consider the dimension of 7 (from the factor x - 7) as the real solution to this problem.

Answer:

Step-by-step explanation:

5 ! = 120

Since 5 ! = 5 × 4 × 3 × 2 × 1, then

5 × 3 = 15 is the greatest odd factor of 5 !

The greatest odd integer that is a factor of 5 factorial (5!) is 5. This is because the definition of factorial involves multiplying a number by every number below it until reaching 1 and 5 is the largest odd number within this range.

The greatest odd integer that is a factor of 5! (or 5 factorial) is 5. The factorial, represented by the symbol '!', is a function that multiplies a number by every number below it until it reaches 1. For example, 5! means 5 * 4 * 3 * 2 * 1. To find the greatest odd integer that is a factor of 5!, you simply need to identify the largest odd number that is a part of this multiplication, which is 5.

Let's clarify this with some simple math. Start from the number 5 itself, then move down: 5 (it's an odd number), 4 (it's even, exclude), 3 (it's odd, but less than 5), 2 (it's even, exclude), 1 (it's odd, but less than 5). Hence, the largest odd integer that is a divisor of 5! is 5.

Answer:

19

Step-by-step explanation:

We can solve this problem using a system of equation in two unknowns.

Let b = number of birds.

Let c = number of cats.

The care of a bird costs $5.50, so for b number of birds, the cost of care is 5.5b.

The care of a cat costs $8.50, so for c number of cats, the cost of care is 8.5c.

The total cost of care for the birds and cats is 5.5b + 8.5c.

The total cost of care is $291.50. This must equal the expression we have above, so we get our first equation.

5.5b + 8.5c = 291.5

The total number of birds and cats is b + c, but we are told it is 41, so our second equation is:

b + c = 41

We now have the following system of two equations in two unknowns.

5.5b + 8.5c = 291.5

b + c = 41

Rewrite the first equation.

Multiply both sides of the second equation by -8.5, and write it under the first equation. Then add the equations.

      5.5b + 8.5c = 291.5

+    -8.5b - 8.5c = -348.50

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

        -3b            = -57

Divide both sides of the equation by -3.

b = 19

Answer: there were 19 birds

By defining the number of birds and cats as variables and setting up a system of equations, we solved for the number of birds to be 19.

Let's define the number of birds as b and the number of cats as c. From the problem, we have the following equations:

b + c = 41 (total number of birds and cats)

5.50b + 8.50c = 291.50 (total cost of caring for birds and cats)

To solve for the number of birds, we follow these steps:

Step 1: Express the number of cats in terms of birds.

From the first equation, we get:

c = 41 - b

Step 2: Substitute this expression into the second equation.

5.50b + 8.50(41 - b) = 291.50

Expand and simplify the equation:

5.50b + 348.50 - 8.50b = 291.50

Combine like terms:

-3b + 348.50 = 291.50

Step 3: Solve for b.

Subtract 348.50 from both sides:

-3b = 291.50 - 348.50

-3b = -57

Divide both sides by -3:

b = 19

Therefore, there were 19 birds at the shelter on Thursday.

[tex]\bf \begin{array}{|c|ll} \cline{1-1} \textit{a\% of b}\\ \cline{1-1} \\ \left( \cfrac{a}{100} \right)\cdot b \\\\ \cline{1-1} \end{array}~\hspace{5em}\stackrel{\textit{75\% of 62500}}{\left( \cfrac{75}{100} \right)62500}\implies 46875[/tex]

Answer:

So, Width  = 7/2 or 3.5

Length =  4

Step-by-step explanation:

Area of rectangle = 14 ft^2

Let width of rectangle 2 = x

and Length of rectangle = 2x-3

Formula used for area of rectangle

Area = Length * Width

14 = (2x - 3) x

14 = 2x^2 - 3x

=> 2x^2 -3x -14 = 0

Solving the quadratic equation using factorization

-28 x^2 = -7x * -4x

2x^2 -7x + 4x -14 = 0

x (2x -7) +2(2x-7) = 0

(x+2) (2x-7) =0

=> x + 2 =0 and 2x -7 = 0

x = -2 and x = 7/2

Since width cannot be negative so, x= 7/2

Width= x = 7/2

Length = 2x -3 => 2(7/2) - 3

=> 7 -3

=> 4

So, Width =  7/2 or 3.5

Length =  4.

Length= 2width-3

Width=x

Length=2x+3

X(2x-3)=14

x must equal 3.5

Length=4

Width=3.5

Answer:

13 < n < 51

Explanation:

Basically to find the lowest possible length, all you need to do is subtract the lower number from the higher number (32 - 19), and to find the greatest possible length, add the lower number and the higher number (32 + 19). Then you'd plug it in to this inequality: a < n < b, a being the difference, and b being the sum. But, if the triangle were a right triangle that would be a whole different story.

Answer:

3 and -1

Step-by-step explanation:

Took the test.

What we are given:

r( x ) = x - 3

s( x ) = 4x²

We have to find:

( s + r )( x ) = ( x - 3 + 4x² )

→ 4x² + x - 3

( s - r )( x ) = ( x - 3 - 4x² )

→ -4x² + x - 3

For the last function, I am confused whether it is a multiplication or composite function, so I am going to do both.

Multiplication:

( x - 3 ( 4x² ))( 2 )

( 4x³ - 12x² )( 2 )

4(2)³ - 12(2)²

4(8) - 12(4)

32 - 48

→ -4

Composite function:

r(s(x))(2) = r(4x²) = 4x² - 3  = 4(2)² - 3 = 4(4) - 3 = 16 - 3

→13

Final answer:

The expressions for (s+r)(x) is 4x^2 + x - 3 and (s-r)(x) is 4x^2 - x + 3. The value of (s.r)(2) is 16.

Explanation:

To find the expression for (s+r)(x), we need to add the functions s(x) and r(x). Adding the two functions, we get (s+r)(x) = 4x^2 + (x-3). Simplifying this expression, (s+r)(x) = 4x^2 + x - 3.

To find the expression for (s-r)(x), we need to subtract the function r(x) from s(x). Subtracting the two functions, we get (s-r)(x) = 4x^2 - (x-3). Simplifying this expression, (s-r)(x) = 4x^2 - x + 3.

To evaluate (s.r)(2), we need to substitute 2 for x in the expression s(x) * r(x). Substituting 2 for x in the expression 4x^2, we get (s.r)(2) = 4(2)^2 = 16.

It's a much more interesting problem when we have to estimate the shadow length from a photo.

The crater is a curvy bumpy surface, but let's approximate it as part of a sphere and just conflate the arc and chord length, so the 400 m shadow corresponds to a 400 m chord from the edge at the surface to the bottom.

The shadow as a chord forms a hypotenuse right triangle with the depth d being the leg opposite the 48 degree angle of the sun.

[tex] d = 400 \sin 48 \approx 297 \textrm{  m}[/tex]

Answer:

an acute triangle

Step-by-step explanation:

Given:

vertex 1 = (7,3)

vertex 2 = (9,0)

vertex 3 = (5,-1)

Now finding the length of each side of the triangle

Using distance formula, to find the length of side between vertex 1 and 2

d=[tex]\sqrt{(x2-x1)^{2}+ (y2-y1)^{2} }[/tex]

Putting values of x1=7 , x2=9, y1=3 and y2=0

d=[tex]\sqrt{(9-7)^{2}+ (0-3)^{2} }\\ =\sqrt{2^{2}+ 3^{2} }\\ =\sqrt{4+9} \\=\sqrt{13}[/tex]

Using distance formula, to find the length of side between vertex 1 and 3

Putting values of x1=7 , x2=5, y1=3 and y2=-1

d=[tex]\sqrt{(5-7)^{2}+ (-1-3)^{2} }\\ =\sqrt{2^{2}+ 4^{2} }\\ =\sqrt{4+16} \\=\sqrt{20[/tex]

Using distance formula, to find the length of side between vertex 2 and 3

Putting values of x1=9 , x2=5, y1=0 and y2=-1

d=[tex]\sqrt{(5-9)^{2}+ (-1-0)^{2} }\\ =\sqrt{4^{2}+ 1^{2} }\\ =\sqrt{16+1} \\=\sqrt{17[/tex]

Hence the three sides of triangle are:

√13, √20, √17

by Pythagoras theorem

if c^2= a^2 + b^2 then triangle is right triangle

if c^2> a^2 + b^2 then triangle is obtuse triangle

if c^2<a^2 + b^2 then triangle is acute triangle

Now let a=√13 b=√17 and c=√20 then:

a^2 + b^2 = 13+17

                 = 30

c^2=20

and 20 < 30 which means c^2<a^2 + b^2 then triangle is acute triangle !

To determine the type of triangle formed by the points G(7,3), H(9, 0), and (5, -1), one needs to calculate the lengths of the sides using the distance formula and then apply the Pythagorean theorem to determine if it is a right, acute, or obtuse triangle.

The coordinates G(7,3), H(9, 0), and (5, -1) can form a triangle on a Cartesian plane, and we need to determine the type of triangle they form. To solve this problem, we need to calculate the lengths of the sides of this triangle using the distance formula, which is √((x2-x1)² + (y2-y1)²) for two points (x1, y1) and (x2, y2). Once we have all three sides, we can determine the type of triangle by applying the Pythagorean theorem, where the square of the length of the longest side (the hypotenuse 'c') is equal to the sum of the squares of the other two sides (a and b).

By applying the Pythagorean theorem, if the sum of the squares of the two shorter sides equals the square of the longest side, the triangle is a right triangle. If the square of the longest side is greater than the sum of the squares of the other two sides, it is an obtuse triangle. And if it’s less, the triangle is an acute triangle.

Given the way the coordinates are arranged in the fragmented information, it appears the triangle they form is relevant to understanding relationships between sides and angles. The mnemonic SOHCAHTOA is often used to remember the ratios of sides in a right triangle. Since the information for determining the lengths of the sides directly is not fully provided, we can't explicitly state the type of triangle formed by the points G(7,3), H(9, 0), and (5, -1) without further calculation.

Answer:

Each friend will get more than 4 whole bagels.

Step-by-step explanation:

First off, although the question asks for 13 bagels divided between 3 friends, let's use a number that results in a whole number when divided by 3, but is close to 13.

This number can be 12.

12 divided by 3 is 4, so each friend gets 4 bagels if there are a total of 12 bagels.

However, there are more than 12 bagels so we know that each of the the 3 friends will get more than 4 bagels each.

Each friend will get 4 whole bagels, with 1 bagel left over.

In a baker's dozen, there are 13 bagels. Hillary, Mark, and Tam share the bagels equally. To determine if each friend will get more than or fewer than 4 whole bagels, we divide the total number of bagels by the number of friends.

13 bagels / 3 friends = 4 remainder 1

Each friend will get 4 whole bagels, with 1 bagel left over.

Division is one of the four basic operations of arithmetic. The other operations are addition, subtraction, and multiplication. What is being divided is called the dividend, which is divided by the divisor, and the result is called the quotient.

What function does this graph represent?

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

The graph

The graph is the graph of a quadratic function

By definition:

A quadratic function is represented as

y = a(x - h)^2 + k

Where

Vertex = (h, k)

From the graph, we have

Vertex = (2, 1)

So, we have

y = a(x - 2)^2 + 1

Using the point (0, 2) on the graph, we have

a(0 - 2)^2 + 1 = 2

4a + 1 = 2

4a = 1

a = 1/4

So, we have

y = 1/4(x - 2)^2 + 1

Hence, the function this graph represent is y = 1/4(x - 2)^2 + 1

[tex]Mean = \frac{Sum}{No.\ of\ values}\\ = \frac{2+4+7+2+3+7+9+3+1+7}{10}\\ = \frac{45}{10}\\ = 4.5[/tex]

Now we have to find deviations.

Note that the deviations are calculated by subtracting the mean from the value. The distance is always positive so the deviations will be positive

Value         Deviation

2                 2-4.5 = |-2.5| = 2.5

4                  4-4.5 = |-0.5| = 0.5

7                  7-4.5 = 2.5

2                 2-4.5 = |-2.5| = 2.5

3                 3-4.5 = |-1.5| = 1.5

7                  7-4.5 = 2.5

9                  9-4.5 = 4.5

3                 3-4.5 = |-1.5| = 1.5

1                 1-4.5 = |-3.5| = 3.5

7                  7-4.5 = 2.5

The last step is to find the mean of deviations.

[tex]Mean\ of\ deviations = \frac{(2.5+0.5+2.5+2.5+1.5+2.5+4.5+1.5+3.5+2.5}{10}\\ = \frac{24}{10} \\=2.4[/tex]
