180° rotation about the origin changes the signs of the coordinates.
(x, y) → (-x, -y)
It is a reflection over the y-axis and a reflection over the x-axis (in either order).

Answer:
100feet
Step-by-step explanation:
Given the height reached by a dolphin expressed by the equation is h = -16t^2 + 80t. At maximum height, the velocity is zero, hence;
v(t) = dh/dt = -32t + 80
0 = -32t + 80
32t = 80
t = 80/32
t = 2.5secs
Substitute t = 2.5 into the height formula h = -16t^2 + 80t
h = -16(2.5)^2 + 80(2.5)
h = -100+200
h = 100feet
Hence the maximum height the dolphin jumps is 100feet
26 x 72 = 1872
40 + 420 + 12 = 472
1872 - 472 = 1400 (the answer)
I'm perdy sure it's 64/1 but yk it could be something else XD :D good luck!
