Heres some info i learend
s but its not complete maybe i guess
Terms. We combine em by adding. The numbers or subtracting the numbers that are multiplied times the radicals.
Odd numbers are not divisible by 2. Only even numbers are visible by 2. Such as, 4,6,8.
Multiples of 10 do always end in 0.
& i'm not so sure about the last one.
Answer:
You can divide them both by two and three.
Step-by-step explanation:
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>
The answer is 0.314 radian
