Which dilation is shown by the graph?

Which Dilation Is Shown By The Graph?

Answers

Answer 1

Answer:

D. D₂ (∆XYZ)

Step-by-step explanation:

Dₙ = (x,y) → ((n)x, (n)y)

_________________

X = (-1, 2).

Y = (2, -1).

Z = (-2, -1).

_________

Dₙ ∆XYZ:

X(-1, 2) → X'(-2, 4)

Y(2, -1) → Y'(4, -2)

Z(-2, -1) → Z'(-4, -2)

______________

-2 / -1 = 2, 4 / 2 = 2.

4 / 2 = 2, -2 / -1 = 2.

-4 / -2 = 2, -2 / -1 = 2.

_______________

D₂ = (x,y) → ((2)x, (2)y).

X(-1, 2) → ((2)(-1), (2)(2)) = X'(-2, 4)

Y(2, -1) → ((2)(2), (2)(-1)) = Y'(4, -2)

Z(-2, -1) → ((2)(-2), (2)(-1)) = Z'(-4, -2)

At 100°F, a certain Insect chirps at a rate of 97 times per minute, and at 102°F, they chirp 111 times per minute. Write an equation in slope-intercept form that represents the situation.​

Answers

Answer:

y = 7x - 603

Step-by-step explanation:

We start by determining the slope:

m = y2 - y1/x2 - x1 = 111 - 97/102 - 100 = 14/2 = 7,

Now we substitute the slope into the slope-intercept equation y  = mx + b, solving for the y-intercept [b]:

111 = 7(102) + b,

b = -603

Equation: y = 7x - 603

1. Anthony threw a ball from the top of a 10-story building that was 165 feet

tall. The equation g(165 - h) = v2 can be used to find the maximum

height the ball can attain after being thrown from the top of the building,

Rewrite the equation to highlight the maximum height attained by the

ball, h.

Answers

Answer:

[tex]h = 165 - \frac{v^2}{g}[/tex]

Step-by-step explanation:

Given

[tex]g(165 - h) = v^2[/tex]

Required

Make h the subject

[tex]g(165 - h) = v^2[/tex]

Divide both sides by g

[tex]165 - h = \frac{v^2}{g}[/tex]

Subtract 165 from both sides

[tex]165 - 165 - h = \frac{v^2}{g} - 165[/tex]

[tex]- h = \frac{v^2}{g} - 165[/tex]

Multiply both sides by -1

[tex]-1 * - h = (\frac{v^2}{g} - 165)*-1[/tex]

[tex]h = 165 - \frac{v^2}{g}[/tex]

Answers

Answer:

9×10 to the power of -8

Step-by-step explanation:

Cause when we add power to the power we multiply them

For example [tex](2^{2} )^2[/tex] , we multiply the power so , 2×2= 4 so [tex](2^{2} )^2[/tex] = [tex]2^{4}[/tex]=16

Same here [tex]((9*10)^{-4} )^2[/tex] we multiply the powers so -4×2=-8

So [tex]((9*10)^{-4} )^2[/tex] =[tex](9*10)^{-8}[/tex] = 2.323×[tex]10^{-16}[/tex]

9x10 to power of -8

Mark works at Target. He works 4 hours a day for a total of 120 days of the year. His hourly rate of pay is $12.50 . How much can he expect to make annually prior to deductions?

Answers

Answer:

$6000

Step-by-step explanation:

total hours worked = total hours worked per day x total days worked in a year

120 x 4 = 480

480 x 12.50 = $6000

A school band gives a year-end concert. It is held in a 400-seat auditorium. Each concert ticket sells for $10, and 85% of the tickets are sold. How much money does the band earn from the sale of the tickets?

Answers

Answer: $3,400

Step-by-step explanation:

There are 400 seats in the auditorium which means that there are 400 tickets to be sold.

85% of these tickets are sold. The number of tickets sold is:

= 85% * 400

= 340 tickets were sold.

Each ticket sells for a total of $10.

The amount of money made from ticket sales is therefore:

= No. of tickets sold * price of ticket

= 340 * 10

= $3,400

your gym membership cost $33 per month after an initial membership fee. you paid a total of $228 after 6 months. writer an equation that gives the cost as a function of the length of your gym membership (in months). find the total cost after 9 months

Answers

Answer:

what i did was multiply 33*6 and got 198 and then 228-198 to find out that the initial fee was 30 dollars. then multiply 33*9+30 to get a  9-month total cost of $327

Step-by-step explanation:

cost = $33 per month + fee  

1.  c(m) = 33m + f

 33(6) + f = 228

198 + f = 228

f = $30 membership fee  

c(m) = 33m + 30

 2.  at 9 months:  33(9) + 30 = $327

hopefully this helps :)
