Step-by-step explanation:
since f'(x) = 2f(x) and f(3) has no term of x (so, there must be a constant that eliminates x for x = 3), we get
f(x) = x²/9 × c
c = m×e^n
f(1) = 1/9 × m×e^n = 5
=> m×e^n = 45
f(3) = 9/9 × m×e^n = 45
m = 45
n = 0

3.9 hours
Answer:
The airplane descends at a rate of 850 feet per minute.
Step-by-step explanation:
y < x; y > 5; x > 2
A. (9; 7) → x = 9; y = 7
y < x → 7 < 9 TRUE
y > 5 → 7 > 5 TRUE
x > 2 → 9 > 2 TRUE
B. (7; 5) → x = 7; y = 5
y > 5 → 5 > 5 FALSE
C. (-3; 8) → x = -3; y = 8
y < x → 8 < -3 FALSE
D. (3; 2) → x = 3; y = 2
y > 5 → 2 > 5 FALSE
E. (8; 6) → x = 8; y = 6
y < x → 6 < 8 TRUE
y > 5 → 6 > 5 TRUE
x > 2 → 8 > 2 TRUE
F. (6; 6) → x = 6; y= 6
y < x → 6 < 6 FALSE
Answer: A. (9; 7) and E. (8; 6)
