This is a tough one :/<br> If f(x) = -x + 7 and g(x) = radical of x– 3,<br> what is (f º g)(4)

Jlenok [28]

Answer:

Step-by-step explanation:

To solve, first plug in 4 as your x value for your g(x) equation.

$g(4)=\sqrt{4-3} \\g(4)=\sqrt{1} \\g(4)=1$

Next, plug in the value of g(4) into your f(x) equation for x.

$f(1)=-1+7\\f(1)=6$

Exercise topic: Permutations and Combinations. A company wants to hire 3 new employees, but there are 8 candidates, 6 of them wh

SOVA2 [1]

Answer:

(a) 56 ways

(b) 6 ways

Step-by-step explanation:

Given:

candidates: 6 mail, 1 female

number to hire : 3

a) In how many different ways can choose new employees?

use the combination formula to choose r to hire out of n candidates

C(n,r) = C(8,3) = 8! / (3! (8-3)! ) = 40320 / (120*6) = 56 ways

b) In how many different ways can choose a single male candidate?

6 ways to choose a male, one way to choose two female, so 6*1 = 6 ways

c) In how many different ways can choose at least one male candidate?

To choose at least 1 male candidate, we subtract the ways to choose no male candidates out of 56.

Since there are only two females, there is no way to choose 3 female candidates.

In other words, there are 56-0 = 56 ways (as in part (a) ) to hire 3 employees with at least one male candidate.

andreyandreev [35.5K]

Let's calculate the total cost per year:
6168 + 3280 + 2190 + 1200 = 12,838.
Four years will cost 12838 x 4 = 51,352
Your family will help you out with 17,600, so you will need to pay:
51352 - 17600 = 33,752
