Question 4
Svetach [21]

A) Composite function that represents how many flowers Iris can expect to bloom over a certain number of weeks is f[s(w)] = 50w + 25.

B) The unit of measurement for the composite function is flowers.

C) Number of the flowers for 30 weeks will be 1525.

<h3>What is a composite function?</h3>

A function is said to be a composite function when a function is written in another function. The composite function that represents the number of flowers is f[s(w)] = 50w + 25. and the number of flowers for 30 weeks is 1525.

Part A: Write a composite function that represents how many flowers Iris can expect to bloom over a certain number of weeks.

From the given data we will find the function for the number of flowers with time.

f(s) = 2s + 25

We have  s(w) = 25w

f[(s(w)]=2s(w) + 25

f[(s(w)] = 2 x ( 25w ) +25

f[s(w)] = 50w + 25.

Part B: What are the units of measurement for the composite function in Part A

The expression f[s(w)] = 50w + 25 will give the number of the flowers blooming over a number of the weeks so the unit of measurement will be flowers.

Part C: Evaluate the composite function in Part A for 30 weeks.

The expression f[s(w)] = 50w + 25 will be used to find the number of flowers blooming in 30 weeks put the value w = 30 to get the number of the flowers.

f[s(w)] = 50w + 25.

f[s(w)] = (50 x 30) + 25.

f[s(w)] = 1525 flowers.

Therefore the composite function is f[s(w)] = 50w + 25. unit will be flowers and the number of flowers in 30 weeks will be 1525.

What is the approximate radius of a sphere with a volume of 1436cm to power of 3
Margarita [4]

Answer:

<h3>The radius is 7 cm</h3>

Step-by-step explanation:

Volume of a sphere is given by

V =  \frac{4}{3} \pi {r}^{3}

where r is the radius

From the question V = 1436 cm³

1436 =  \frac{4}{3} \pi {r}^{3}

Multiply through by 3

We have

4308 = 4\pi {r}^{3}

Divide both sides by 4π

{r}^{3}  =  \frac{4308}{4\pi}

{r}^{ 3}  =  \frac{1077}{\pi}

Find the cube root of both sides

r =  \sqrt[3]{ \frac{1077}{\pi} }

r = 6.99

We have the final answer as

<h3>r = 7cm</h3>

Hope this helps
