Hey there!

Use this formula:

$a^{-b} =\frac{1}{a^{b} }$

Remember this formula.

Now, let's solve the given problem.

$5^{-9} =\frac{1}{5^{9} }$

Hope this helps you!

1. Jeremy has $12000 cash to invest in the bank compounded at 4% interest annually.

Answer:

$A(x) = 12000(1.04)^x$

Step-by-step explanation:

Compound interest:

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.

$12000 cash

This means that $P = 12000$

Compounded at 4% interest annually.

This means that $r = 0.04, n = 1$

What equation will calculate the value in x years?

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

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

$A(x) = 12000(1 + 0.04)^x$

$A(x) = 12000(1.04)^x$

Factor completely 4ab − 7ax + 8b − 14x.

ASHA 777 [7]

4ab + 7ax + 8b - 14x
a(4b - 7x) + 2(4b - 7x)
(4b - 7x)(a + 2)

The answer is: (4b - 7x)(a + 2).

$\dfrac{14+a}{13}=12$
$14+a=13\cdot 12$
$14+a=156$
$a=156-14$
$\boxed{a=142}$

Answer:

13.60 See the note below.

Step-by-step explanation:

Remark

This is just the reverse of the question you just did. This time you are trying to solve for c

Givens

a = 8
b = 11
c = ??

Solution

c^2 = a^2 + b^2 Substitute the givens.

c^2 = 8^2 + 11^2 Expand

c^2 = 64 + 121 Combine the right side by adding

c^2 = 185 Take the square root of both sides.

sqrt(c^2) = sqrt(185) Complete the operation

c = 13.601 Round to the nearest 1/100 th

c = 13.60 Note: the zero must be there or the answer does not show the nearest 1/100 th
