perimeter = 2width + 2 length
102 = 2(x+9) + 2x
102 = 2x + 18 +2x
102 = 4x +18
84 = 4x
21 = x
Length = x = 21 inches
Width = x + 9 = 21 + 9 = 30 inches
V= W × H × L
81000 = 30 × H × 45
81000 = 1350× H
81000/1350 = 1350/1350× H
H = 60 cm
14^ 0.08t = 56.
From here, you can rewrite it as log base 14 argument 56 = 0.08t.
When you plug it in t is about 19
Answer: ≈19 years
Answer:
z³ subtract z⁹ gives you z⁶ but it's a negative right now so you would flip it and get 1 over z6
The maximum profit, as taught in calculus, can be determined when you equate the first derivative of the function to zero. So,
P' = 300 + 0
Hence, the maximum profit is 300.
I'm not sure about the vertices, though. Anyhow, I hope I was able to help you. Have a good day.
