Answer: The correct option is fourth option, i.e., -3.

Explanation:

It is given that the smaller triangle is a preimage of the bigger triangle. The center of dilation is (2, −2).

From the given figure it is noticed that the vertices of preimage are A(2,-2), B(2,2), C(-2,-2) and the vertices of preimage are A'(2,-2), B'(2,-14) and C'(14,-2).

The length of AB is 4 and the length of A'B' is 12.

The sides of image and preimage are in proportion.

proportion = \frac{12}{4} =3

Since the image is enlargement of preimage therefore k>1 and k<-1.

Since the image and preimage are lies in opposite sides of center of dilation, therefore the scale factor must be negative.

k=-3

There correct option is option 4.

What % of 40 is 15? Please put how u do it
andriy [413]

Answer:

37.5

Step-by-step explanation:

so x% of 40 is 15

the equation for that is

x/100 * 40 = 15

40x/100 = 15

multiply 100 on both sides

40x = 1500

divide 40 on both sides

37.5

37.5% of 40 is 15

An equation for annealing soda-lime glass is y(t)=−14t+500 , where t is time in minutes and y is the temperature of the glass in
beks73 [17]

An equation for annealing soda-lime glass is y(t)=−14t+500 , where t is time in minutes and y is the temperature of the glass in ˚C.

To find the y intercept , we plug in 0 for t

y intercept is the value , where time is 0 minutes

so we plug in 0 for t  and find out y(0)

y(t)=−14t+500

y(0)=−14(0)+500 = 500

When t=0 , the value of y = 500

So , y intercept is (0,500)
