ok so first we would do the function d(x) = 3(8)+2

which when solved turns out to be 26

we would then do the function h(x) = 2(26) +7

which when solved turns out to be 59

so he would need 59 dollars for the donuts

To determine what percentage of 376 teachers at a university were female, Ryan randomly selected 14 teachers. He then collected

Kipish [7]

Answer:

a)There are 14 teachers in Ryan's sample, and 362 teachers in the population.

Step-by-step explanation:

Population:-

The totality of observations with which we are concerned, whether this number be finite or infinite is called population.

Given data population is 376 teachers at a university were female'

Sample:-

A sample is a subset of a Population

sample of given data = 14teachers

The percentage of 376 teachers at a university were female, Ryan randomly selected 14 teachers.

$p = \frac{14}{376} = 0.0372$ = 3.72%

A. 11 cm^3 B. 14 cm^3 C. 15 cm^3 D. 25 cm^3

IgorLugansk [536]

Lets get started :)

We need to find the radius of the larger cylinder

V = $\pi$ r²h
960 = $\pi$ r²(16)
$\frac{960}{16} = \pi r^2$
60 = $\pi r^2$
$\frac{60}{ \pi } = r^2$
r = $\sqrt{ \frac{60}{ \pi } }$
r ≈ 4.27 cm

The ratio of the bigger cylinder to smaller is:
16 : 4

Therefore, the big cylinder is 4 times bigger than the small cylinder

$\frac{4.37}{4}$ = r
r = 1.09 cm (radius of small cyclinder)

V (small cylinder) = $\pi$ (1.09)²(4)
= 15 cm³

Your answer will be C. 15 cm³

Find the inverse of the function.

asambeis [7]

Answer:

A) $f^{-1}(n)= (n+2)^3$

Step-by-step explanation:

$f(n) = \sqrt[3]{n} -2$

$y = \sqrt[3]{n} -2$

$y = n^{1/3}-2$

$n = y^{1/3} -2$

$n + 2 = y^{1/3}$

$y = (n + 2) ^3$

$f^{-1}(n) = (n + 2)^3$

Hope this helps!

Please help me, how do you do this

lina2011 [118]

Answer:

84x+50

Step-by-step explanation:

First, you would find the area of the entire square. The area of a square is LW, so you would multiply (7x+6)(7x+6). For this, I would use the FOIL method, so you would multiply the first terms which would be (7x)(7x)=14x^2. Then the outside terms, so (7x)(6)=42x. Then the inside, so (7x)(6)=42x. Finally, the last terms, 6(6)=36.

Then you would combine them, so the area of the whole square is $14x^{2} +42x+42x+36$ which would equal $14x^{2} +84x+36$ .

Then, the area of the smaller square is (x)(x) which would equal $x^{2}$ .

Then you would subtract the smaller square from the bigger one, so the final answer would be $14+84x+36$ which you could simplify to $84x+50$
