The inverse function is:

g(x) = 27*x^3 - 4

And g(2) = 212.

<h3>How to get the inverse function?</h3>

We need to find g(x) such that:

g(h(x)) = x.

We know that:

h(x) = \frac{\sqrt[3]{x + 4} }{3}

Then our function must be a cubic, multiplied by 3^3 = 27, and then subtracts 4, it is:

g(x) = 27*x^3 - 4

As you can see, if you evaluate in h(x), the outcome is x.

Now we can evaluate this in x = 2, we get:

g(2) = 27*2^3 - 4 = 212

The correct option is C.

Dina and Masha started out on a 10 km bike path at the same time. When Dina reached the end of the 10 km, Masha still had 2 km t
german

Answer:

4 km/h

Step-by-step explanation:

We are told that Dina and Masha started out on a 10 km bike path at the same time.

Dina's biking speed is 5 km/h.

Let us find taken by Dina to cover 10 kn distance.

\text{Time}=\frac{\text{Distance}}{\text{Speed}}

\text{Time taken by Dina to cover 10 km}=\frac{10km}{5\frac{km}{hr}}

\text{Time taken by Dina to cover 10 km}=\frac{10km}{5}\times \frac{hr}{km}}

\text{Time taken by Dina to cover 10 km}=2hr

Therefore, Dina took 2 hours to complete 10 km.

Since both started at the same time, therefore, Masha also took 2 hours to complete 2 km less than Dina.

Let us find distance covered by Masha.

\text{Distance covered by Masha}=10\text{ km}-2\text{ km}=8\text{ km}

Now let us find Masha's biking speed.

\text{Speed}=\frac{\text{Distance}}{\text{Time}}

\text{Masha's biking speed}=\frac{8\text{ km}}{2\text{ hour}}

\text{Masha's biking speed}=4\frac{\text{ km}}{\text{ hour}}

Therefore, Masha's biking speed is 4 km per hour.

2^5*2^negative 3 simplify​
Citrus2011 [14]

Answer:

4

Step-by-step explanation:

Simplify the following:

2^5/2^3

Hint: | For all exponents, a^n/a^m = a^(n - m). Apply this to 2^5/2^3.

Combine powers. 2^5/2^3 = 2^(5 - 3):

2^(5 - 3)

Hint: | Subtract 3 from 5.

5 - 3 = 2:

2^2

Hint: | Evaluate 2^2.

2^2 = 4:
