A large university accepts 70% of the students who apply. Of the students the university accepts, 40% actually enroll. If 30,000 students apply, how many actually enroll?

Answers

8400 because you take 70% of 30000 which is 21000, then you take 40% of 21000, which is 8400

Answer:

8400 students

Step-by-step explanation:

Applicants = xAccepted = 70% ⇒ 0.7xEnrolled = 40% ⇒ 0.4(0.7x) = 0.28x

We got x = 30000

Then number of actually enrolled is:

30000*0.28 = 8400 students

Let f be the function defined by f(x)=x^3+x^2+x. Let g(x)=f^-1(x), where g(3)=1. What is the value of g'(3)?

Answers

Answer:

1/6

Step-by-step explanation:

Given the function

f(x)=x^3+x^2+x

Get the inverse. Let y = f(x)

y = x^3+x^2+x

Replace y with x

x = y³+y²+y

Differentiate with respect to x

1 =3y²dy/dx + 2ydy/dx + dy/dx

1 = (3y²+2y+1)dy/dx

dy/dx = 1/3y²+2y+1

g'(x) = 1/3(g(x))²+2g(x)+1

If x = 3

g'(3) = 1/3(g(3))²+2g(3)+1

g'(3) =1/3(1)²+2(1)+1

g'(3) = 1/3+2+1

g'(3) = 1/6

Hence g'(3) = 1/6

solve for x and the measures for x=4

Answers

Answer:

Below in bold.

Step-by-step explanation:

The angles on the line AC add up to 180 degrees, so:

11x - 8 + 90 + 6x + 2 + 4x + 12 = 180

21x + 96 = 180

21x = 180 - 96 = 84

x = 84/21

x = 4.

<ABD = 11(4) - 8 = 36 degrees.

<EBF = 6(4) + 2 = 26 degrees.

<CBF = 4(4) + 12 = 28 degrees.
