Step-by-step explanation:

we see clearly that the side (leg) lengths changed from 3 units to 1 unit.

so, the scale factor is 1/3.

answer D is correct.

I assume the center of the dilation is the origin (0, 0).

so, C' becomes (-1, 0), A' becomes (-2, 0), B becomes (-2, 1).

it was then reflected across the y-axis (flipped over from the left side of the y-axis to the right side).

C'' becomes (1, 0), A'' (2, 0), B'' (2, 1).

and then it was translated (shifted) by (+1, -2), so that

C''' = D = (2, -2), A''' = F = (3, -2), B''' = E = (3, -1)

Sean tossed a coin off a bridge into the stream below. The path of the coin can be represented by the equation h = -16t2 + 72t +

boyakko [2]

Answer:

about 5.613 seconds

Step-by-step explanation:

Using the quadratic formula to find the value of t when h = 0, we have ...

at² +bt +c = 0

t = (-b±√(b²-4ac))/(2a)

t = (-72±√(72² -4(-16)(100)))/(2(-16))

t = (-72±√11584)/-32 = (9±√181)/4

Only the positive value of t is of interest.

The coin will hit the stream after (9+√181)/4 seconds ≈ 5.613 seconds.

P2q2+pq–q3–p3 = for p=0.5 and q = −0.5 Please help!!!

Aleksandr [31]

In order to answer the question, we simply substitute the value of p and q to the given expression and solve. We do as follows:

P^2q^2+pq–q^3–p^3
0.5^2(-0.5)^2+0.5(-0.5)–(-0.5)^3–(0.5)^3
-3/16 or -0.1875

Hope this answers the question. Have a nice day.

The table below represents the number of math problems Jana completed as a function of the number of minutes since she began doi

Sonbull [250]

It's a nonlinear because the x and y values are not increasing at the same ratio each time. This would be an example of a linear function:
x l 1 2 3 4 5 6
y l 3 6 9 12 15 18

As x increases by 1, y increases by a multiple of 3
