Hmm, I need someone to answer this. Just answer it right, if you don't know it then don't answer, It's annoying. It's probably r

eally hard, (because no one has answered it correctly, Yet).
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. (4 points)


Part B: What are the units of measurement for the composite function in Part A? (2 points)


Part C: Evaluate the composite function in Part A for 30 weeks. (4 points)

Please help, and please show how you did the work.

Thanks and Good Luck

Answer:

Step-by-step explanation:

A)

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

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

f(w)=50w+25

B)

The ujits for the composite function are f=number of flowers and w=number of weeks.

C)

f(30)=50(30)+25

f(30)=1500+25

f(30)=1525

Answer:

g(x) = - sqrt(x+8) reflected about the x axis and shifted 8 units to the left

h(x) = 2 sqrt(x) +1 is stretched by 2 in the y direction and shifted up 1 in the y direction

Step-by-step explanation:

y = f(x + C)  C > 0 moves it left

So we moved it 8 units to the left

y = −f(x)  Reflects it about x-axis

g(x) = - sqrt(x+8) reflected about the x axis and shifted 8 units to the left

y = f(x) + C  C > 0 moves it up

so we moved it up 1 units

y = Cf(x)  C > 1 stretches it in the y-direction

and stretched it by 2 in the y direction

h(x) = 2 sqrt(x) +1 is stretched by 2 in the y direction and shifted up 1 in the y direction

In 2014 the population of Kenya was estimated to be 45,121,040 with a growth rate of 2.7%. Question 1 Use the exponential growth
Vlad [161]

Answer:

  y = 45,121,040×1.027^t

Step-by-step explanation:

An exponential growth equation is generally of the form ...

  value at time t = (initial value)(growth factor)^t

where the growth factor is the multiplier for a period equal to one time unit.

Here, the initial value (in 2014) is 45,121,040. The growth factor is given as 1.027 (2.7% added per year), and we can define t as the number of years after 2014. Then our equation is ...

  y = 45,121,040×1.027^t . . . . where t = years after 2014

What is a rule for
USPshnik [31]

Answer:

Step-by-step explanation:f(h(x))= 2x -21

f(x)= x^3 - 6

h(x)=\sqrt[3]{2x-15}

WE need to find f(h(x)), use composition of functions

Plug in h(x)

f(h(x))=f(\sqrt[3]{2x-15})

Now we plug in f(x) in f(x)

f(h(x))=f(\sqrt[3]{2x-15})=(\sqrt[3]{2x-15})^3 - 6

cube and cube root will get cancelled

f(h(x))= 2x-15 -6= 2 x-21

Which is a correct way of graphing the line y = –x – 2?
katen-ka-za [31]
Y = -x - 2.....in y = mx + b form, the m represents the slope and the b represents the y int. (and if u didnt already know, -x is the same as -1x)

so in ur equation, the slope is -1 and the y intercept is -2....or (0,-2)

so u would plot (0,-2) and use the slope of -1 to plot another point. Draw a line through the points.
