Aperson wants to have $25,000 cash for a new car 5 years from now. how much should be placed in an account now if the account pays 4.75% compounded weekly? compute the answer to the nearest dollar.

Future value of an investment at 4.75% compounded weekly is $25,000

The present value of the investment, to the nearest dollar

The multiplier is (1 + .0475/52)^(52·5) ≈ 1.2679375, so the amount required is found from

... 1.2679375×present value = 25,000

... present value = 25,000/1.2679375 ≈ 19,717

$19,717 needs to be placed in the account now.

When an annual interest rate r is compounded n times per year, the annual multiplier is (1 +r/n)^n. Here, we have n=52 (weeks per year). The multiplier is applied 5 times (raised to the 5th power) to obtain the result of a 5-year investment.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
