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

The critical value t* gets larger as the confidence level increases. True or false?
posledela

Answer:

We can find the critical value t_{\alpha/2}

And for this case if the confidence increase the critical value increase so then this statement is True

Step-by-step explanation:

For a confidence level given c, we can find the significance level like this:

\alpha=1 -c

And with the degrees of freedom given by:

df=n-1

We can find the critical value t_{\alpha/2}

And for this case if the confidence increase the critical value increase so then this statement is True

Evaluate 8(7x--3) when x=9
Schach [20]

I will assume that by "Evaluate 8(7x--3) when x=9" you meant:

"Evaluate 8(7x-3) when x=9."

First, substitute 9 for x in 7x-3: 7(9)-3 = 60. Rewrite the problem as:

8(60). Multiply. Answer: 480

Valentin [98]

Answer:

errr polynomials ahaha

so basically we can multiply the power outside of the parantheses with the exponents on the inside:

so

-3x^{2*4} y^{1*4}

this will give us:

-3x^8y^4

we also unfortunately, have to use the power on the coefficient -3 as well  and we cant just MULTIPLY -3 by 4, we are going to have to multiply -3 with -3 4 TIMES(anytime we see a coefficient we MUST multiply the coefficient by itself according to the number outside of the parantheses)

so:

-3*-3*-3*-3=81

final expression

81x^{8}y^{4}
