Answer:

-6

Step-by-step explanation:

[tex]m^2-36=0[/tex]

Adding 36 on both sides gives:

[tex]m^2=36[/tex]

Square rooting both sides:

[tex]m=\pm \sqrt{36}[/tex]

[tex]m=\pm 6[/tex]

So if square -6 , you will get 36 just like when you square 6.

That is [tex](-6)^2=6^2=36[/tex]

Answer:

-6

Step-by-step explanation:

If one solution to the problem m²-36=0 is 6, the other solution is -6.

(m + 6) • (m - 6)  = 0

Any solution of term = 0 solves product = 0 as well.

m+6 = 0  

m = -6

m-6 = 0

m = 6

Answer:

32.49

Step-by-step explanation:

First you must set up the probably and plug in the variables into the formula. Sthe formula would turn into the equation: C=30.99 (c for cost) + .5 [r for tax] (30.99) c for cost. Then you will solve the equation:

1. C= 30.99+.5(30.99)

2. C= 30.99+ 1.50

3. C= 32.49

Answer:

The total cost of the shoes is $32.5395.

Step-by-step explanation:

The equation that you must use is [tex]C=p+p\times r[/tex]. Keep in mind that percentage number is the number divided by 100 in real numbers. For example, 5% equals 0.05. So, instead of using the term 5%, you must use 0.05.

Now, let's replace the variables in the equation with the data that the problem gives.

[tex]C=p+p\times r[/tex]

[tex]C=(30.99)+(30.99)\times (0.05)[/tex]

[tex]C=30.99+1.5495[/tex]

The term $1.5495 refers to the tax that must be paid for the shoes. The total cost is the sum of the price and the tax.

[tex]C=32.5395[/tex]

Thus, the total cost of the shoes is $32.5395.

Answer:

Height of light post = 33 feet

Step-by-step explanation:

We will use the trigonometric ratios to find the height of light post

The given scenario forms a right angled triangle with the right angle with the light post.

The distance between light post and the person is the base.

So, base = b = 40 feet

The height of light post will be the perpendicular

So,

Perpendicular = p = x

Angle = 35°

So,

tan (angle) = p/b

tan 35° = p/40

0.7002 =p/40

0.7002*40 = p

p = 28 feet

Since the persons eye level is 5 feet from the ground, 5 feet will be added to perpendicular for actual height of light post.

Height of light post = 28+5 = 33 feet ..

Answer:

Step-by-step explanation:

Answer:

A) 0.0194

B) 1.94%

C) $ 170,000

Step-by-step explanation:

Value of house in 1992 = P = $ 120,000

Value of house in 2007 = S = $ 160,000

Time difference from 1992 to 2007 = 15 years

Part A)

The formula of compound interest is:

[tex]S=P(1+r)^{t}[/tex]

P is the original amount i.e. $ 120,000

t is the time in years which is 15 years

S is the amount after t years which is $ 160,000

r is the annual growth rate

Using the values, we get:

[tex]160000=120000(1+r)^{15}\\\\\frac{160000}{120000}=(1+r)^{15}\\\\ \frac{4}{3}=(1+r)^{15}\\\\(\frac{4}{3} )^{\frac{1}{15}}=1+r\\\\ r=(\frac{4}{3} )^{\frac{1}{15}}-1\\\\ r=0.0194[/tex]

Thus, the annual growth rate is 0.0194

Part B)

In order to convert a decimal to percentage, simply multiply the decimal by 100.

So, 0.0194 in percentage would be 1.94%

Part C)

We have to find the value of house in 2010 i.e. after 18 years. So t =18

Using the values in the formula, we get:

[tex]S=120000(1+0.0194)^{18}\\\\ S=169584[/tex]

Rounded to nearest thousand dollars, the value of the house would be $ 170,000

Answer choice C, location C

Step-by-step explanation:

If you add or subtract the standard deviation to the monthly profit, then you get $19,371.18 and $22,295.48. This shows that the deviation withholds most of the data given

The store location for which  [tex]68%[/tex]% of the data lies between $19,371.18 and $22.295.48 is location C

What is standard deviation?

Standard deviation explains the relation of data with mean.

How to find the location of the data?

For normal distributions, 68% of the data lies under one SD from the mean. Two standard deviations is within  95%, and three standard deviations would take up to 99%.

This implies that on taking (mean + SD) and (mean - SD), 68% of data would cover these two numbers.

 Add and subtract SD from the mean to check which location will give $19,371.18 and $22.295.48.

For location A, we have

M-SD=23,124.70-1553.43=21,571.27

M SD = 23,124.70 + 1,553.43 = 24,678.4

For location B, we have

M - SD = 24,842.18 - 1,617.20 = 23,224.98

M + SD = 24, 842.18 + 1,617.20 = 26,459.38

For location C, we have

M - SD = 20,833.33 - 1,462.15 = 19,371.18

M + SD = 20,833.33 + 1,462.15 = 22,295.48

This implies the store location is C

Answer:

75 in^2

Step-by-step explanation:

L = 3W here.  Also, P = 2W + 2L = 40 in here.  Subbing 3W for L, we get

                                    2W + 2(3W) = 40, or

                                     2W + 6W = 40, or 8W = 40.  Thus, W = 5 in and L = 15 in

and the area is W*L, or 5(15) in^2, or 75 in^2

The width of the rectangle is 5 inches and the length is 15 inches. Therefore, the area of this rectangle is 75 square inches.

Let's indicate the width of the rectangle as 'w'. Given the length is three times the width, it would be represented as '3w'. The perimeter of any rectangle is calculated as 2*(length + width). Therefore, 2*(w + 3w) = 40. Solving this, we get 'w' as 5 inches and, therefore, the length as 15 inches.

The area of a rectangle is calculated by multiplying the length and width. Therefore, the area of this rectangle would be length * width = 15*5 = 75 square inches.

Answer:

1/4

Step-by-step explanation:

y varies directly as x means you should translate this as y=kx.

y varies indirectly as x means you should translate this as y=k/x.

Anyways we had directly, so the equation is of the form y=kx for any point (x,y) where k is the constant.

We are given y=kx and that this equation should satisfy (x,y)=(8,2).

So let's plug in 8 for x and 2 for y giving us

2=k*8

Divide both sides by 8:

2/8=k

Simplify:

1/4=k

So k is a constant, that constant, the never changing number, for the point (x,y) is 1/4.

That means the equation is y=1/4 *x. The 1/4 is the constant of variation, also called the constant of proportionality.

The constant of variation, in this case, is found to be 1/4 using the formula y = kx.

The constant of variation in this case is 1/4.

Given that y varies directly as x and y = 2 when x = 8, we can use the formula y = kx to find the constant of variation.

By substituting the values y = 2 and x = 8 into the formula, we get 2 = k * 8, which simplifies to k = 1/4.

Answer:

* The values of x are 0 and 4

Step-by-step explanation:

* Lets explain how to solve the problem

- f(x) = x² - 2x - 4 is a quadratic function

- g(x) = 2x - 4

∵ f(x) and g(x) are intersected

∴ They meet each other in a point

- To find this point equate the two functions

∵ f(x) = g(x)

∵ f(x) = x² - 2x - 4

∵ g(x) = 2x - 4

∴ x² - 2x - 4 = 2x - 4 ⇒ subtract 2x from both sides

∴ x² - 4x - 4 = -4

- Add 4 to both sides

∴ x² - 4x = 0

- Take x as a common factor

∴ x(x - 4) = 0

- Equate each factor by 0

∴ x = 0

- OR

∴ x - 4 = 0 ⇒ add 4 to both sides

∴ x = 4

∴ f(x) and g(x) intersected at x = 0 and x = 4

* The values of x are 0 and 4

The length of a chord whose central angle is 75° in a circle with a radius of 12 inches is 14.6 inches.

A circle is the set of all points in the plane that are a fixed distance (the radius) from a fixed point (the center)

A central angle is an angle with endpoints and located on a circle's circumference and vertex located at the circle's center

[tex]cos A = \frac{b^{2}+c^{2}-a^{2}}{2bc}[/tex], where a, b ,c are the sides opposite to ∠A, ∠B, ∠C respectively.

In triangle, let ∠A = 75°.

∴ We can write, [tex]cos 75 = \frac{b^{2}+c^{2}-a^{2}}{2bc}[/tex].

So,  we can write,

(cos 75)(2 x 12 x 12) = (12)² + (12)² - a²

Answer:

7 pieces

Step-by-step explanation:

Stock that must be available at the beginning of each month = 26 yards

Since,

1 yard = 36 inches

26 yards = 26 x 36 = 936 inches

This means 936 inches of fabric must be available at beginning of each month.

Current Inventory:

4 pieces that are each 22 1/2 (or 22.5) inches long. So total length of these fabrics =  4 x 22.5 = 90 inches

3 pieces that each 33 inches long. So total length of these fabrics = 3 x 33 = 99 inches

Therefore, the total length of current inventory = 90 + 99 = 189 inches.

Length of fabric needed more:

Length of fabric that must be bought more = 936 - 189 = 747 inches

It is given that the fabric must be bought in pieces are the 3 yards long. 3 yards is equal to 108 inches.

So,  I have to buy pieces that are each 108 inches long and I need to complete 747 inches in total.

Therefore, the number of pieces that I need to buy = [tex]\frac{747}{108}=6.9[/tex]

Step-by-step explanation:

There are 3 conditions for the difference of squares.

The correct answer is B and C

Final answer:

Binomials that are a difference of squares have the form a² - b² and can be factored into (a + b)(a - b), where both terms are perfect squares. Examples include x² - 9 and 4y² - 25.

Explanation:

To determine which binomials are a difference of squares, we look for expressions in the form of a2 - b2. A difference of squares can be factored into (a + b)(a - b), where a and b are any expressions. It is essential that both terms be perfect squares and that they are subtracted from one another.

For example, x2 - 9 is a difference of squares as it can be factored into (x + 3)(x - 3), where both x2 and 9 are perfect squares. Another example could be 4y2 - 25, which factors to (2y + 5)(2y - 5). Keep in mind that if the sign is not subtraction, or if either term is not a perfect square, the binomial does not represent a difference of squares. The correct choice of examples, factoring process, and the nature of perfect squares are essential to identify differences of squares accurately.

We are asked to find the [tex]34^{th}[/tex] term in the sequence which is denoted by  [tex]a_{34}[/tex].

We first need to know what type of sequence is given in the question.

A sequence where the difference between the consecutive terms is always the same.

The formula used to find the value of the required term is given by:

[tex]a_n = a + (n-1)d[/tex]

Where a = first term, n = the term value and d = common difference.

The given sequence is 9,6,3,.....

Now there is another transformation.

f(x)=x^2

a*f(x) means it is either being vertically stretched or compressed.  a also tells if we have a reflection (if a is negative) or not (if a is positive).

n(x)=2x^2 means it has been vertically stretched by a factor of 2.

Let's put it altogether.

g(x)=2x^2+5

means the parent function has been vertically stretched by a factor of 2 and moved up 5 units

The transformations applied to f(x) to create g(x) involve a vertical stretching by a factor of 2 and a vertical shift upward by 5 units. These modifications result in a parabolic curve that is steeper and shifted upwards compared to the original f(x).

To transform the function [tex]f(x) = x^2[/tex]  into [tex]g(x) = 2x^2 + 5,[/tex] several alterations are made.

First, the function is scaled vertically by a factor of 2.

This means that the output values of g(x) are twice as large as those of f(x) for any given input.

This vertical stretching increases the steepness of the parabolic curve.

Secondly, a constant term of 5 is added to g(x).

This shifts the entire graph of the function vertically upward by 5 units, creating an upward shift.

Consequently, g(x) is now centered 5 units above f(x).
