i divided 42 by 2 to get how many rivets it took to build one ft. i got (21)

21 rivets for 1 ft

next i divided 2200 ft by 21 rivets (2200÷21)= 104.76

Anna also wants to travel after graduation but she isn’t working while in school so she won’t be able to put money aside regular

Molodets [167]

Answer:

She will have $2792 at the end of her four year investment

Step-by-step explanation:

The compound interest formula is given by:

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

Where 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 and t is the time in years for which the money is invested or borrowed.

Gift of $2500:

This means that $P = 2500$

She shopped around and found a 4 year GIC investment that earns 2.8% interest annually.

This means that $t = 4, r = 0.028, n = 1$ .

How much will Anna have at the end of her four year investment?

This is A(4). So

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

$A(4) = 2500(1 + 0.028)^{4} = 2792$

She will have $2792 at the end of her four year investment

which expression is equal to 4 to the power of 5 times 4 to the power of -7 divided by 4 to the power of -2

valentina_108 [34]

Step-by-step explanation:

4⁵ × 4^-7 / 4^-2

it is important to understand that a negative exponent means 1/...

a^-n = 1/(a^n)

in that sense we have therefore

4⁵ × 1/4⁷ × 4² (as (1/ 1/a^n) = a^n)

4⁵ × 4² × 1/4⁷ = 4⁷ × 1/4⁷ = 1

so, "1" is the fully simplified expression equal to the original expression.
