Answer:
A
Step-by-step explanation:
Given the exponential function
f(t) = 228
← where t is time in years
Substitute t = 20 into f(t), that is
f(20) = 228 × 
= 228 × 0.60268.... ≈ 137 → A
Answer:
-216
(-6)^3
Step-by-step explanation:
-6 * (-6*-6)

This is -6 multiplied together 3 times
(-6) ^3
Answer: The unit rate is 65 miles per hour.
Step-by-step explanation:
Use the midpoint formula
(x1 + x2/2, y1 + y2/2)
Input the corresponding numbers
(-12 +5/2, 3 + -10/2)
(-7/2,-7/2)
So, the midpoint of the line segment is (-7/2,-7/2)
