Answers

Answer 1

f(x) + 3, translates f(x) 3 units up

In this case, the function is y = 2x² - 2.

Applying the above rule, we get:

y = 2x² - 2 + 3

y = 2x² + 1

If you are given a rectangle, what are the degrees of its rotational symmetry? (I need all of them between but not including 0 and 360 degrees)

Answers

A rectangle is an Order 2 of symmetry because it matchs its fugure only 2 times while rotating through 360 degrees.

The degrees of symmetry can be calculated as:

[tex]\frac{360\degree}{\text{Order}}=\frac{360\degree}{2}=180\degree[/tex]

We see that at 180 degrees of rotation the shape is identical to the original shape.

This does not repeat for any other angle between 0 and 360 degrees.

x=-6 is undefined

y=-6 is 0 or m = 0

y=-6x is -6 or m = -6

Answer:

1. undefined

2. 0

3. -6

Step-by-step explanation:

Slope-intercept form: y = mx + b

m = slope

b = y-intercept.

Since the equation x = -6 is a vertical line, the slope is undefined.

Since y = -6 is a horizontal line, the slope is 0.

The slope of y = -6x is -6. This is because it is the coefficient of the variable x.

A cookie recipe calls for 3/4 of a cup of flour and makes 2dozen cookies. How many cookies can Julia make if she has 12cups of flour and wants to use it all

Answers

Given that 3/4 of a cup of flour is used to cook 2 dozen cookies,

[tex]\frac{3}{4}\text{ cup of flour}\equiv2\text{ dozen cookies}[/tex]

Consider the conversion,

[tex]1\text{ dozen}=12\text{ units}[/tex]

So it follows that,

[tex]\frac{3}{4}\text{ cup of flour}\equiv2\cdot12=24\text{ cookies}[/tex]

Multiply both sides by 4/3 as follows,

[tex]\begin{gathered} \frac{3}{4}\cdot\frac{4}{3}\text{ cups of flour}\equiv24\cdot\frac{4}{3}\text{ cookies} \\ 1\text{ cup of flour}\equiv32\text{ cookies} \end{gathered}[/tex]

So, 32 cookies can be cooked using 1 cup pf flour.

Given that Julia has 12 cups of flour, so the number of cookies that she can cook, is calculated as,

[tex]12\text{ cups of flour}\equiv32\cdot12=384\text{ cookies.}[/tex]

Thus, Julia can make 384 cookies if she uses 12 cups of flour.

triangle XZW ~ triangle XYV, find the perimeter of triangle XZW

Answers

176.4

Explanation

as the triangle are similar we can set a proportion

Step 1

find the YZ value

a) let

[tex]ratio1=\frac{hypotenuse}{rigth\text{ side}}[/tex]

so,for triangle XZW

[tex]ratio=\frac{40+32}{28+YZ}[/tex]

and for triangle XYV

[tex]ratio=\frac{40}{28}[/tex]

as the ratios are equal, we can set a proportion

[tex]\frac{40+32}{28+YZ}=\frac{40}{28}[/tex]

b) now,solve for YZ

[tex]\begin{gathered} \frac{40+32}{28+YZ}=\frac{40}{28} \\ \frac{72}{28+YZ}=\frac{40}{28} \\ cross\text{ multiply} \\ 72*28=40(28+YZ) \\ 2016=1120+40YZ \\ subtract\text{ 1120 in both sides} \\ 2016-1120=1120+40YZ-1120 \\ 896=40YZ \\ divide\text{ bothsides by 40} \\ \frac{896}{40}=\frac{40YZ}{40} \\ 22.4=YZ \end{gathered}[/tex]

so

YZ=22.4

Step 2

find the length of the side WZ

a) let

[tex]ratio=\frac{hypotenuse\text{ }}{base}[/tex]

hence

[tex]\begin{gathered} ratio_1=\frac{40+32}{WZ}=\frac{72}{WZ} \\ ratio_2=\frac{40}{30} \end{gathered}[/tex]

set the proportion and solve for YZ

[tex]\begin{gathered} ratio_1=\text{ ratio}_2 \\ \frac{72}{WZ}=\frac{40}{30} \\ cross\text{ multiply} \\ 72*30=40WZ \\ 2160=40WZ \\ divide\text{ both sides by 40} \\ \frac{2160}{40}=\frac{40WZ}{40} \\ 54=WZ \end{gathered}[/tex]

Step 3

finally, find the perimeter of triangle XZW

Perimeter is the distance around the edge of a shape,so

[tex]Perimeter_{\Delta XZW}=XY+YZ+ZW+WV+VX[/tex]

replace and calculate

[tex]\begin{gathered} Per\imaginaryI meter_{\Delta XZW}=XY+YZ+ZW+WV+VX \\ Perimeter_{\Delta XZW}=28+22.4+54+32+40 \\ Perimeter_{\Delta XZW}=176.4 \end{gathered}[/tex]

Answers

A relation is a function if an input value has only one output value. This means that a value of x must have only one value of y. Looking at the options,

1) for x = 1, there are different values of y. They include y = 0, 1, 3

for x = 3, y = 0, 1

This means that it is not a function

2) No value of x has more than one value of y. Thus, no input has more than one output. This means that it is a function

3) for x = 2, there are different values of y. They include y = 7, 1

This means that it is not a function

4) for x = 9, there are different values of y. They include y = - 3, 3

for x = 2, there are different values of y. They include y = - 2, 2

This means that it is not a function

on all sales. If Just sold $82,975 worth of jewelry
last month, how much would he make for the
month including his base salary and commission?

Answers

The total salary earned by the Justin including the commission is $3959.25.

What exactly is the commission?A commission is extra money earned based on job performance.Members believe to be paid a specified amount of money depending on achievement marketed, sessions closed, recruits placed, and so on—when they agree to a commission-based position as well as commission framework (more by signing the agreement).

For the given question;

The base salary of Justin is $1500.

The commission earned by Justin is 3%.

The jewelry of worth $82,975 last month.

Let x be the total commission earned.

Then,

3% of 82,975 = x

x = 3× 82,975 / 100

x = $2489.25

Total salary = base salary  + commission

Total salary =  $1500 +  $2489.25

Total salary = $3959.25

Thus, the total salary earned by the Justin including the commission is $3959.25.

Real world compositions: A manufacturer sells a lawn mower to a store at $75 over the manufacturing cost. The store then sells the lawn mower for 140% of the price paid to the manufacturer. Determine the function of the price of a lawn mower in terms of the cost to manufacture the mower. What price will a customer pay for this mower if the manufacturer's cost was $230? Solve using composite functions

Answers

From the information provided, the lawn mower is sold at a price which is $75 over the cost of manufacture.

If the cost of manufacture is x, then we would have;

[tex]f(x)=x+75[/tex]

Also, the store now sells the lawn mower for 140% of the price paid to the manufacturer. Therefore, we would have;

[tex]g(x)=f(x)1.4[/tex]

Hence, if the manufacturer's cost is $230, the customer would be paying g(x). When the cost x is now given as 230, we wou;d have;

[tex]\begin{gathered} f(230)=230+75 \\ f(230)=305 \\ \text{Hence;} \\ g(x)=f(x)1.4 \\ g(x)=305\times1.4 \\ g(x)=427 \end{gathered}[/tex]

ANSWER:

The function of the price is;

[tex]f(x)=x+75[/tex]

The price a customer pays when the cost of manufacturing is $230 would now be $427

Louis food out six different size at the picnic at the end of the picnic he noticed this about about the pies one whole apple pie was eaten and 3/4

Answers

Louis had 6 different pies. Some of them were eating and we want to know how much pie there's left. First, we have the information that one apple pie was entirely gone. From this, we know there were 5 pies remaining.

[tex]6-1=5[/tex]

Then, he also noticed the other apple pie had 3/4 gone. Which means that 1/4 of this second apple pie was leftover.

[tex]1-\frac{3}{4}=\frac{1}{4}[/tex]

Applying this same logic, we can deduct all the slices that were eaten from the total amount of pie we had at first to get the leftovers.

[tex]\begin{gathered} 6-1-\frac{3}{4}-\frac{1}{2}-\frac{1}{8}-\frac{5}{8}-\frac{3}{4} \\ =5-\frac{1}{2}-\frac{6}{4}-\frac{6}{8} \\ =5-2-\frac{3}{4} \\ =3-\frac{3}{4} \\ =2+\frac{1}{4} \end{gathered}[/tex]

What we've done in this last equation, was taking our first amount of pies (6), subtract the whole apple pie that was eaten (1), the three quarters that were eaten from the other apple pie (3/4) and the other eaten slices from the others.

Which means, the result of this calculation is our amount of leftover slices.

We still have 2 and a quarter pies.

From the table, we have the following points:

Let's find the regression line.

Apply the slope-intercept form:

y = mx + b

Where m is the slope and b is the y-intercept.

To find the slope, apply the formula:

[tex]m=\frac{n(\Sigma xy)-\Sigma x\Sigma y}{n(\Sigma x^2)-(\Sigma x)^2}[/tex]

Where:

• ∑x = 1.6 + 1.6 + 1.75 + 1.95 + 2 + 2 + 2.3 + 2.5 = 15.7

• n is the number of data = 8

Now, plug in values into the equation and solve for m:

[tex]\begin{gathered} m=\frac{8(378.1)-15.7*200}{8(31.525)-(15.7)^2} \\ \\ m=-20.175\approx20.2 \end{gathered}[/tex]

The slope, m = -20.2

To find the y-intercept, b, apply the formula:

[tex]\begin{gathered} b=\frac{(\Sigma y)(\Sigma x^2)-\Sigma x\Sigma xy}{n(\Sigma x^2)-(\Sigma x)^2} \\ \\ b=\frac{200(31.525)-15.7*200}{8(31.525)-15.7^2} \\ \\ b=64.594\approx64.6 \end{gathered}[/tex]

Therefore, the regression equation is:

y = 64.6 + (-20.2)x

(b). Substitute 1.8 for x in the equation and solve for y:

y = -20.2(1.8) + 64.6

y = 28.24 = 28.

ANSWER:

(A). y = 64.6 + (-20.2)x

(B). 28
