Answer:
C
Step-by-step explanation:
The exponential function has standard form
y = a 
Use the 2 given points to find a and b
Using (3, 182.25) , then
182.25 = a b³ → (1)
Using (2, 202.5) , then
202.5 = ab² → (2)
Divide (1) by (2)
= 
b = 0.9
Substitute b = 0.9 into (1) and solve for a
182.25 = a (0.9)³ ( divide both sides by (0.9)³
a =
= 250
Thus
f(x) = 250 ×
← third option
If b=7 and h=4, the area is 14, because the equation for the area of a triangle is 1/2 • b • h.
Answer:
B
Step-by-step explanation: Because he gains $25, which is positive
5, 9, 12, 21, 28, 32, 33, 45, 69, 71,
28+32/2 = 30
The median is 30
