Keep doing 4 over 1000 until the four reaches the 1000. If four does not go into 1000, then reduce the fraction 4/1000.

Mrs. Galicia has a cupcake company. The amount of money earned is represented by

sashaice [31]

Using the profit function, it is found that:

a) She earns $36 after 25 years.

b) The function was shifted right 4 units and up 1 units.

<h3>What is the profit function?</h3>

The profit, in x years after 2015, is given by:

$p(x) = 12\sqrt[3]{x + 2}$

Item a:

She earns $36 after x years, considering x for which p(x) = 36, hence:

$p(x) = 12\sqrt[3]{x + 2}$

$36 = 12\sqrt[3]{x + 2}$

$\sqrt[3]{x + 2} = 3$

$(\sqrt[3]{x + 2})^3 = 3^3$

$x + 2 = 27$

$x = 25$

She earns $36 after 25 years.

Item b:

The new function is:

$h(x) = 12\sqrt[3]{x - 2} + 1$

At the domain, we have that $x + 2 \rightarrow x - 2$ , that is, $x \rightarrow x - 4$ , hence it was shifted right 4 units.

At the range, we have that $h(x) = h(x - 4) + 1$ , hence it was shifted up 1 unit.

Calculate 8 ∙ 10-4 divided by 2 ∙ 102. (box after the "10" in answer is for the exponent.). ∙ 10

Korolek [52]

Given problem: $\frac{8*10^{-4}}{2*10^2}$ .

Solution: We can see that first we have 8 and 2 numbers in front of 10's powers.

So, we need to simplify 8 over 2 first.

If we divide 8 by 2, we get 4.

Now, let us work on 10's and their powers.

$10^{-4}$ is being divided by $10^{2}.$

We can apply quotient rule of exponents remaining part.

According to quotient rule of exponents, $\frac{a^m}{a^n}=a^{m-n}$

If we apply same rule, we need to subtract exponents of 10's.

$\frac{10^{-4}}{10^2}=10^{-4-(-2)}$

If we simplify exponent part -4-(-2), it will give us -4+2 =-2.

So, $10^{-4-(-2)}=10^{-2}$

And final answer would be $4 \times 10^{-2}$ .
