Answer:

There are duplicate letter choices for example, two E's and three Hs so be sure to choose the right one

1, ⇔ A 3221.21

2 ⇔ E 10.13

3 ⇔ H 133.63

4 ⇔ L 11.59

---------------------------------------

5 ⇔ H 346.77

6 ⇔ E 1.35

7 ⇔ R 0.54

8. ⇔ T 0.02

----------------------------------

9 ⇔ O
f(t) = 33,000( 1- 0.27)^t

10 ⇔ H
f(t) = 9.56(1.03)^t

11 ⇔ F
f(t) = 5(1+ 0.125)^t\\

12 ⇔ T
f(t) = 4000(1.01)^t

Explanation:

These questions can be solved by plugging in the value of each of the given variables into each equation and solving using a calculator

I will provide the solution steps for one from each batch.
Q1 - Q4
t = 4

Q1.

y =275 ( 1 + 0.85)^4\\\\= 275(1.85)^4\\\\= 275 * 11.71350625\\\\= 3221. 21 \text{ to the nearest hundredth}

You really don't have to compute (1.85)⁴ separately; most calculators can do everything in one shot

Correct answer: A

-----------------------------------------------------------------------------------------------------

5 - 8
Q8

h(t) = 0.8\left((3)/(5)\right)^t \\\\\text{When t = 7}\\h(7) = 0.8\left((3)/(5)\right)^7 \\\\= 0.8(0.6)^7 \;\;\;\;\left((3)/(5) = 0.6} \right)\\\\= 08 * 0.0279936\\\\= 0.02239488\\\\= 0.02\text{ to the nearest hundredth}

Corresponds to T

--------------------------------------------------------------------------------------------

9 - 12

You can determine all of these by looking at the multiplier in the given equations for f(t) where the multiplier is the constant outside the parentheses

Question 9
Multiplier is 33,000 so the equation is

f(t) = 33,000( 1- 0.27)^t ==> O

Question 10
Answer choice ==> H

Question 11
Answer Choice ==> F

Question 12
Answer choice ==> T
