Iris is a botanist who works for a garden that many tourists visit. The function f(s) = 2s + 25 represents the number of flowers that bloomed, where s is the number of seeds she planted. The function s(w) = 25w represents the number of seeds she plants per week, where w represents the number of weeks.
Part A: Write a composite function that represents how many flowers Iris can expect to bloom over a certain number of weeks.
Part B: What are the units of measurement for the composite function in Part A?
Part C: Evaluate the composite function in Part A for 30 weeks.

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

(b)Number of flowers for a given number of weeks

(c)f(30)=1525 flowers

Step-by-step explanation:

Number of flowers that bloomed, f(s) = 2s + 25, s=Number of seeds planted

Number of seeds planted per week, s(w) = 25w, w=Number of weeks

Part A

f(s) = 2s + 25

Substituting s(w) = 25w into f(s)

f(s(w))=2(25w) + 25=50w+25

The composite function is: f(w)=50w+25

Part B

The unit of measurement of the composite function above is Number of flowers that bloomed for a given number of weeks.

Part C

If w=30 weeks

Then from the function, f(w)=50w+25

f(30)=50(30)+25=1500+25=1525 flowers

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
