Using compound interest, it is found that:
- The equation is:
- After 3 years, he has $4,252 in the account.
- After 10 years, he has $6,608 in the account.
<h3>What is compound interest?</h3>
The amount of money earned, in compound interest, after t years, is given by:
In which:
- A(t) is the amount of money after t years.
- P is the principal(the initial sum of money).
- r is the interest rate(as a decimal value).
- n is the number of times that interest is compounded per year.
- t is the time in years for which the money is invested or borrowed.
In this problem:
- Jack was given $3520 from his grandma, hence P = 3520.
- The account pays 6.5% interest rate that is compounded annually, hence n = 1, r = 0.065.
Hence, the equation is:
After 3 and 10 years, respectively, the amount in dollars in the account are given by:

Sorry, the way this is written is a little confusing, but I’m assuming you mean the equation is x^2 + 18x + 12? Sorry if I’m mistaken. If this happens to be the case, then the a value would be 1, the b value would be 18, and the c value would be 12. Again I’m assuming this is in the ax^2 + bx + c formula. I hope this helps, sorry if I’m wrong :/
Answer:
42 w^6 y^9
Step-by-step explanation:
Simplify the following:
3×7×2 w^5 y^7 y^2 w
3 w^5 y^7×7 y^2×2 w = 3 w^(5 + 1) y^(7 + 2)×7×2:
3×7×2 w^(5 + 1) y^(7 + 2)
7 + 2 = 9:
3×7×2 w^(5 + 1) y^9
5 + 1 = 6:
3×7×2 w^6 y^9
3×7 = 21:
21×2 w^6 y^9
21×2 = 42:
Answer: 42 w^6 y^9
