Answer:

x = 10

Step-by-step explanation:

x = 4 + (4x-4) ^ (1/2)

First, we rewrite the expression:

x = 4 + (4x-4) ^ (1/2)

x = 2 (2+ (x-1) ^ (1/2))

x = 4 + 2 (x-1) ^ (1/2)

From here we get a solution for x = 10

To check it we substitute x = 10 in the expression:

10 = 4 + 2 (10-1) ^ (1/2)

10 = 4 + 2 (9) ^ (1/2)

10 = 4 + 2 (3)

10 = 4 + 6

10 = 10

Answer:

The solution is:

x = 10

Iris is a botanist who works for a garden that many tourists visit. the function f(s) = 2s + 25 represents the number of flowers
7nadin3 [17]

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(w)=50w+25 and the number of flowers for 30 weeks is 1525.

Given that:

f(s)=2s+25

s(w)=25w

The number of flowers to bloom over w weeks is calculated using the following composite function: f(w)

f(s)=2s+25

Replace s with s(w)

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

Substitute (w)=25w

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

f(s(w))=50w+25

Hence:

f(w)=50w+25

The units of the measurement of f(w) are flowers

The number of flowers for 30 weeks means:

w=30

So, we have:

f(w)=50w+25

f(30)=50 * 30+25

f(30)=1525

Hence, the number of flowers for 30 weeks is 1525
