I do not know the answer to the question
Answer:
(a) After t years, the height is
18t² + 3t + 10
(b) The shrubs are847 cm tall when they are sold.
Step-by-step explanation:
Given growth rate
dh/dt = 1.8t + 3
dh = (18t + 3)dt
Integrating this, we have
h = 18t² + 3t + C
When t = 0, h = 10cm
Then
10 = C
So
(a) h = 18t² + 3t + 10
(b) Because they are sold after every 9 years, then at t = 9
h = 18(9)² + 3(9) + 10
= 810 + 27 + 10
= 847 cm
Answer:
the height is 14
Step-by-step explanation:
since the volume in a rect. prism is V = width x height x length, and the width times length is the area of the base, for height we need to do 840/60 to find the height
840/60 = 14
Answer:
9+13=22.
Step-by-step explanation:
the number 9 is the square number. the number 13 is the prime number
