Answer:

There are many possible solutions. For example,

(2^3)^4 = ((2^5)^12)/((2^6)^8) = 2^10 x 2^2 = (2^19)/(2^7)

(2^2)^5 = ((2^6)^11)/((2^7)^8) = 2^1 x 2^9 = (2^20)/(2^10)

If a bed costs £33 in the sale with 25% off what was the price before

Volgvan

I would like to say 44, but Im not positive.
But, 44x25% would equal 11. And 44-11(aka 25%) would equal 33.

You may want to double check my work though. Hope this helps

A principal of $4500 is invested at 5.75% Interest, compounded annually. How much will the investment be worth after 5 years?

Mila [183]

Answer:

$5,951.33

Step-by-step explanation:

We can use the compound interest formula to solve this problem:

$A=P(1+\frac{r}{n} )^{nt}$

P = initial balance

r = interest rate (decimal)

n = number of times compounded annually

t = time

First, change 5.75% into a decimal:

5.75% -> $\frac{5.75}{100}$ -> 0.0575

Now, plug in the values:

$A=4,500(1+\frac{0.0575}{1})^{1(5)}$

$A=5,951.33$

After 5 years, the investment will be worth $5,951.33
