If $2940 is invested at 3.2% compounded quarterly, how much is in the account after 8 years?
tino4ka555 [31]

Answer:

The future value is $3793.776

Step-by-step explanation:

Given

PV = 2940 --- present value

r = 3.2\% --- rate

t = 8 --- time

n = 4 --- quarterly

Required

Determine the future value

This is calculated using:

FV = PV(1 + \frac{r}{n})^{nt

So, we have:

FV =2940 * (1 + \frac{3.2\%}{4})^{4*8

FV =2940 * (1 + \frac{3.2}{400})^{32

FV =2940 * (1 + 0.008)^{32

FV =2940 * (1.008)^{32

FV =2940 * 1.2904

FV =3793.776

Question 17
Rufina [12.5K]

Answer:

698 fishes

Step-by-step explanation:

Generally, we can represent an exponential growth function as;

y = a•(1 + r)^t

originally, there were 3 fishes

The original value in this case means a = 3

After 6 weeks, there were 31

31 in this case is y

r is the increase percentage or rate

t is the time

So, we have it that;

31 = 3•(1 + r)^6

31/3 = (1 + r)^6

10.33 = (1 + r)^6

ln 10.33 = 6 ln (1 + r)

ln 10.33/6 = ln (1 + r)

e^0.3892 = (1 + r)

1 + r = 1.476

r = 1.476-1

r = 0.476 or 47.6%

So the growth percentage or rate is 47.6%

For 14 weeks, we simply have the value of t as 14;

So ;

y = 3•(1 + 0.476)^14

y = 3(1.476)^14

y = 698 fishes

Free_Kalibri [48]

Answer:14in

Step-by-step explanation:

volume(v)=196π

Height(h)=1

Radius=√(v ➗ π x h)

Radius=√(196π ➗ πx1)

Radius=√(196)

Radius=14in
