There were 750 books sold last week at side bookstore. The table below summarizes these books by genre. This information is also presented as a circle graph. Find the central angle measure x, for self help slice in the circle graph. Do not round.

Answers

we have that

total books sold=750

self help=117

the percentage of self-help books is equal to

117/750=0.156=15.6%

Remember that

in the complete circle, the angle of 360 degrees represents the 100%

so

Applying proportion

Find out the measure of angle x for a percentage equal to 15.6%

360/100=x/15.6

solve for x

x=(360/100)*15.6

x=56.16 degrees

The slope of a line that passes through points (x1, y1) and (x2, y2) is computed as follows:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

The line of the picture passes through (0, 20000) and (40, 0) then its slope is:

[tex]m=\frac{0-20000}{40-0}=-500[/tex]

The y-intercept of the line is (0, 20000)

Slope-intercept form of a line:

y = mx + b

where m is the slope and b is the y-coordinate of the y-intercept. Replacing with m = -500 and b = 20000, we get:

y = -500x + 20000

Rewrite the product (15y)(4x) using the Commutative Property of Multiplication.(15x)(4y)19xy(4x)(15y)(4y)(15x)

Answers

Answer:

(4x)(15y)

Explanation:

The commutative property of multiplication says that

(a)(b) = (b)(a)

Where a and b are the factors. In this case, the factors are 15y and 4x, so

(15y)(4x) = (4x)(15y)

Therefore, the answer is

Number of bottles: 6

Coupon discount on each bottle: $0.50

Final price: $5.10

If p is the regular price of each bottle, then 6p is the regular price of 6 bottles. This means that we have used 6 coupons of $0.50, so the total discount should be 6*0.50 dollars. We subtract this amount from the regular price (6p), leading to $5.10. The equation that represents this situation is:

What is equation of line in slope intercept form?

The most general form of equation of line in slope intercept form is given by y = mx + c

Where m is the slope of the line and c is the y intercept of the line.

Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.

If [tex]\theta[/tex]  is the angle that the line makes with the positive direction of x axis, then slope (m) is given by

m = [tex]tan\theta[/tex]

The distance from the origin to the point where the line cuts the x axis is the x intercept of the line.

The distance from the origin to the point where the line cuts the y axis is the y intercept of the line.

The graph passes through (5, 20), (10, 40), (15, 60)

Slope =

[tex]\frac{40 -20}{10 - 5}\\\\\frac{20}{5}\\\\4[/tex]

Equation of line

k - 20 =4(t - 5)

k - 20 = 4t - 20

k = 4t

This is the equation which shows how many kilometers of range the bicycle gains (k) based on how many minutes it charges (t)

The n = 3 row of Pascal's Triangle has the following entries: 1, 3, 3, and 1TrueFalse

Answers

Ok, in the Pascal Triangle, the element in the row number n and column number p is given by:

So let's take n=3 and find all the entries of that row. We are going to use 0, 1, 2 and 3 as possible values for p.

For p=0:

[tex]\frac{3!}{0!(3-0)!}=\frac{6}{1\cdot3!}=\frac{6}{6}=1[/tex]

For p=1:

[tex]\frac{3!}{1!\cdot(3-1)!}=\frac{6}{2!}=\frac{6}{2}=3[/tex]

For p=2:

[tex]\frac{3!}{2!\cdot(3-2)!}=\frac{6}{2\cdot1!}=\frac{6}{2}=3[/tex]

And for p=3:

[tex]\frac{3!}{3!\cdot(3-3)!}=\frac{3!}{3!\cdot0!}=\frac{3!}{3!}=1[/tex]

So the four entries in the third row of Pascal's Triangle are 1, 3, 3 and 1 so the statement is true.

Answers

In order to find the total displacement of a 8 meters north vector and a 8 meters east vector, we first need to know that these vectors forms a right angle (because the north and east directions forms a 90° angle).

So, to find the final displacement, we need to sum these vectors, and this sum can be calculated using the Pythagoras' theorem in the resultant triangle:

[tex]\begin{gathered} d^2=8^2+8^2 \\ d^2=64+64 \\ d^2=128 \\ d=\sqrt{128=8\sqrt{2=}}11.31 \end{gathered}[/tex]

The total volume of a tree increases
8% each year. What will its volume be
after 7 years if its volume is 5 cubic
meters now?
A) 5(1.08)^7
B) 5(7)(0.08)
C) 5(0.08)^7
D) 5(7)(1.08)

Answers

Answer:

A

Step-by-step explanation:

it all starts with 5 m³.

after one year this will be

5 × 1.08

as the original 5 m³ have increased by 8% (= multiplication by 1.08, as 8% = 0.08, and adding 8% means 100% + 8% = 1 + 0.08 = 1.08).

after the second year we will see another increase by 8% compared to the previous year.

so,

(5 × 1.08) × 1.08 = 5(1.08)²

...

and so, after the nth year, the volume is

5(1.08)^n

therefore, after 7 years means n = 7, and we get

5(1.08)⁷

Consider the line . y=3/2x+3Find the equation of the line that is parallel to this line and passes through the point .(-8,3)Find the equation of the line that is perpendicular to this line and passes through the point . (-8,3)

Answers

Answer:

Equation of parallel line: y = 3x/2 + 15

Equation of perpendicular line: y = - 2x/3 - 7/3

Explanation:

The equation of a line in the slope intercept form is expressed as

y = mx + c

where

m represents slope

c represents y intercept

The equation of the given line is

y = 3x/2 + 3

By comparing with the slope intercept equation,

slope, m = 3/2

Recall, if two lines are parallel, it means that they have the same slope. Thus, the slope of the parallel line passing through the point, (- 8, 3) is 3/2. We would find the y intercept, c by substituting m = 3/2, x = - 8 and y = 3 into the slope intercept equation. We have

3 = 3/2 * - 8 + c

3 = - 12 + c

c = 3 + 12 = 15

By substituting m = 3/2 and c = 15 into the slope intercept equation, the equation of the parallel line passing through the point, (- 8, 3) is

y = 3x/2 + 15

Recall, if two lines are perpendicular, it means that the slope of one line is the negative reciprocal of the slope of the other line. Thus, the slope of the perpendicular line passing through the point, (- 8, 3) is - 2/3. We would find the y intercept, c by substituting m = - 2/3, x = - 8 and y = 3 into the slope intercept equation. We have

3 = - 2/3 * - 8 + c

3 = 16/3 + c

c = 3 - 16/3 = - 7/3

By substituting m = - 2/3 and c = - 7/3 into the slope intercept equation, the equation of the perpendicular line passing through the point, (- 8, 3) is

y = - 2x/3 - 7/3

For each of the following letters, find the equation for a polynomial function whose graph resembles the given letter: U, N, M, and W.

Answers

We are asked to determine polynomic functions which graph resembles the given letters.

For the letter U we will use a second-degree polynomial, which means a polynomial of the form:

[tex]y=ax^2+b[/tex]

Is we take the values of "a" and "b" to be:

[tex]\begin{gathered} a=1 \\ b=0 \end{gathered}[/tex]

We get the function:

[tex]y=x{}^2[/tex]

The graph is the following:

Now, to determine a function that resembles the letter N we will use a polynomic function of third-degree, this means a function of the form:

[tex]y=ax^3+bx^2+cx+d[/tex]

We will use the following values for the constants:

[tex]\begin{gathered} a=\frac{1}{4} \\ \\ b=1 \\ c=0 \\ d=0 \end{gathered}[/tex]

Substituting we get:

[tex]y=\frac{1}{4}x{}^3+x^2[/tex]

The graph of the function is:

To determine a polynomial that resembles the letter "m" we will use a polynomial that has 3 x-intercepts and the end-points are pointing down. This means that the function is of the form:

[tex]y=-(x-a)(x-b)^2(x-c)[/tex]

The middle term has a square because we want the middle intercept to be tangent to the x-axis. Giving values to the constant we get:

[tex]y=-(x+1)(x-1)^2(x-3)[/tex]

The graph of the function is:

Now, we determine a function that resembles the letter "W". We will use a polynomial with two intercepts that are tangent to the x-axis and the end behavior must be upwards. Therefore, the function must be of the form:

[tex]y=(x-a)^2(x-b)^2[/tex]

We will use a = -1 and b = 1:

[tex]y=(x+1)^2(x-1)^2[/tex]
