You want to purchase a new car in 55
Tanzania [10]

Answer:

Ans. you should deposit each month to end up with $38,000 the amount of $533.33 every month for 5 years at a APR of 6.5%

Step-by-step explanation:

Hi, first we have to convert all the data to monthly basis, that is, 5 years (5*12=60 months) and the rate of 6.5% APR offered by the bank (Monthly rate = 0.065/12=0,005666667  or 0.5667% monthly)

With that in mind, we need to solve for "A" the following equation.

FV=\frac{A((1+r)^{n}-1) }{r}

Where:

FV = Future value of the car

r = rate of return offered by the bank

n = number of periods that you are going to make the monthly deposit

That is:

38,000=\frac{A((1+0,005667)^{60}-1) }{0,005667}

38,000=\frac{A(0,403599896)}{0,005667}

38,000=A(71,22351103)

A= 533,53

Best of luck.

A person invested $420 in an account growing at a rate allowing the money to double
AURORKA [14]

Answer:

t=11.9

Step-by-step explanation:

960=420(2)^t/10

2.28571429=2^t/10

add log to both sides

log(2.28571429)=10 t  log(2)

divide by log 2

1.19264508=  10 /t

10(1.19264508)

11.926450779=t

Perform the indicated operation.<br> h(n)=n-3<br> g(n)=-2n² + 2<br> Find (hºg)(n)
Anni [7]

Step-by-step explanation:

h(n) = n - 3 \\ g(n) =  - 2 {n}^{2}  + 2 \\  \\ (h.g)(n) = h(n).g(n)  \\  = (n - 3).( - 2 {n}^{2}  + 2) \\  = n( - 2 {n}^{2}  + 2) - 3( - 2 {n}^{2}  + 2) \\  =  - 2 {n}^{3}  + 2n + 6{n}^{2}   - 6 \\    \red{\boxed {\bold{\therefore \: (h.g)(n) = - 2 {n}^{3}+ 6{n}^{2} + 2n  - 6}}}
