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

Step-by-step explanation:
what system
Answer:
Step-by-step explanation:
first of all the question is wrong 1 kilogram = 2.2046 pounds. and 1 pound = 0.4536kilogram.
if we want to convert 112lb into kilogram. we multiply it by 0.4536.
ie 112lb = 112x0.4536kg = 50.8032kg
to convert lb to kg you do this; lb x 0.4536
to convert kg to lb you do this; kg x 2.2046
The first and last choices are true.
First Choice:
7 of a total of 16 cells should be shaded.
Last Choice:
Double the numerator and denominator of 6:8. 12 is greater than 7 (12:16 and 7:16)
Hope it helped and I hope those are the correct answers.
