Answer:
the length of the stripe is 20.82inches
Step-by-step explanation:
given
height of can = 5in
circumference = 12in
π = 3.142
the circumference of the base = 2πr = 12
radius of base = 1.91in
if the stripe wind once round the can (circumference length), it will start from the radius base to the radius top.
the total length of the stripe = 2radius + circumference of can + height
= 2(1.91) + 12 + 5 = 20.82inches
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>
