Answer:

Step-by-step explanation:
All three functions in the figure are parabolic and thus share the parent function
. They are horizontally dilated by some constant (unless they aren't) and can all be represented with
, where
is some constant.
Plug in point the line passes through to find that constant. For
, we can see the function clearly passes through (2,4):

Therefore, the function of
is 
Answer: option B

Answer:
5 miles per hour
Step-by-step explanation:
Anna runs 6 1/4 miles in 1 1/4hours. What is her rate in miles per hour?
6 1/4 miles / 1 1/4 hours =
25/4 miles / 5/4 hours =
5 mph or miles per hour or miles/hour
V(t) = dy/dt = 40 - 32t
ai). average velocity = (v(0.5) - v(0))/(0.5 - 0) = ((40 - 32(0.5)) - (40 - 32(0)))/0.5 = (40 - 16 - 40)/0.5 = -16/0.5 = -32m / s
ii). average velocity = (v(0.1) - v(0))/(0.1 - 0) = ((40 - 32(0.1)) - (40 - 32(0)))/0.1 = (40 - 3.2 - 40)/0.1 = -3.2/0.1 = -32m / s
iii). average velocity = (v(0.05) - v(0))/(0.05 - 0) = ((40 - 32(0.05)) - (40 - 32(0)))/0.05 = (40 - 1.6 - 40)/0.05 = -1.6/0.05 = -32m / s
