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.

Given that angle a = 45°, work out x.<br><br><br> The diagram is not drawn accurately.
Romashka-Z-Leto [24]

Answer:

X = 45

Step-by-step explanation:

90 + X + A = 180 (angles of a triangle sum to 180)

90 + X + 45 = 180

X = 45

Complete the missing value in the solution to the equation.
snow_lady [41]

Answer:

y = − 1

Hope this helps!

Step-by-step explanation:

Alright so this is our equation:

y − 3   =   2 ( x − 1 )

We will substitute:

x = − 1

So now our equation looks like this:

y − 3   =   2 ( −1 − 1 )

Now we will get rid of the parentheses:

y − 3    =   − 2 − 2

Solve the left side:

y − 3   =   − 4

Now add 3 on both sides to find out what y is:

y − 3   =   − 4

  +3         +3

Add:

y = − 1

Yay! We found our answer! Nice job everyone!
