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
Your main choices here are (1) a calculator with statistical functions and (2) a table of z-scores.
(a) On my TI-83 Plus calculator I typed in normcdf(-1000, 0.92). The calculator returned the value 0.821. This is approx. 8/10 of the total area under the std normal curve.
(b) I typed in normcdf(-1000, -1.26) and got 0.104
(c) I typed in normcdf(-1000, -0.64) and got 0.261
(d) I typed in normcdf(-1000, -1.09) and got 0.138
Answer:
i believed its a=-3
Step-by-step explanation:
-2(a-3)=12
-2a+6=12
-2a=6
divide -2
a=-3
