It would be 0.068 x $2029.20 which is 137.9856. Then you take away 137.9856 from $2029.20 which is equal to $1,891.2144
Answer:
<u>The exponential model is: Cost after n years = 400 * (1 + 0.02)ⁿ</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Cost of the TV set in 1999 = US$ 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:
yes
Step-by-step explanation:
because the lines show that those two sides are congruent, and because there are two congruent sides, then the third has to be the same to connect the triangles
To find the interest accrued for the month, you will use the interest formula I = prt. P stands for the principal (the amount of money borrowed), r is the interest rate, and t is the time period. Because the interest rate is an annual (yearly) interest rate, you will use the fraction 1/12 in your calculation. The math would be $500 x 0.2899 x 1/12. This equals an interest charge of $12.08.
