Answer: A
Step-by-step explanation:
When you use the distributive property, you are multiplying every term in the parentheses by the number outside of it. You are typically multiplying so that is how you will get the simplified form of your equation.
Answer:
<u>The exponential model is: Cost after n years = 400 * (1 + 0.02)ⁿ</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Cost of the TV set in 1999 = US$ 400
Annual increase rate = 2% = 0.02
2. Write an exponential model to represent this data.
Cost after n years = Cost in 1999 * (1 + r)ⁿ
where r = 0.02 and n = the number of years since 1999
Replacing with the real values for 2020, we have:
Cost after 21 years = 400 * (1 + 0.02)²¹
Cost after 21 years = 400 * 1.5157
Cost after 21 years = $ 606.28
The TV set costs $ 606.28 in 2020.
<u>The exponential model is: Cost after n years = 400 * (1 + 0.02)ⁿ</u>
Answer: 3/4
Step-by-step explanation: 3/4 equals .75
Answer:
39.27
Step-by-step explanation:
Calculate whole area of circle - pi5^2 = 78.54
Divide answer by 2 as only half of the circle is shaded - 78.54/2 = 39.27
