Answer:
P = -16(x -28)² +1024
Step-by-step explanation:
The equation can be written in vertex form as ...
P = -a(x -h)² +k
where (h, k) is the vertex, and 'a' is a scale factor. We are given the vertex (h, k) = (28, 1024) and another point (x, P) = (10, -4160). Using these points, we can find the value of 'a'.
-4160 = -a(10 -28)² +1024
-5184 = -324a . . . . simplilfy
a = 5184/324 = 16 . . . . divide by the coefficient of 'a'
A suitable quadratic relation is ...
P = -16(x -28)² +1024
Answer:
the slope is 5

Answer:
B
Step-by-step explanation:
I'm not %100 sure but I'm not guessing either
Your scaling in the x direction is OK, but you didn't scale in the y direction properly. Hint. Scale each vertex of the original rectangle independently to construct the scaled rectangle.
I see the original points and their scaling by 2 as
(2,2) - Scales to (2*2, 2*2) = (4,4) OK in your drawing.
(-2,2) - Scales to (-2*2, 2*2) = (-4,4) OK in your drawing.
(2,5) - Scales to (2*2, 5*2) = (4,10) Error in your drawing.
(-2,5) - Scales to (-2*2, 5*2) = (-4,10) Error in your drawing.
We know when adding a negative and a negative, it will make the negative number bigger
So, (-12) + (-5) = -17
Hope this helps you
