3. Find f[h(a+4)], given the functions below. *
mote1985 [20]

Answer:

C 5a^2 +70a +240

Step-by-step explanation:

We have given these following functions:

f(x) = 5x, g(x) = -2x + 1, h(x) = x^2 + 6x + 8

h(a+4)

This function is:

h(a+4) = (a+4)^2 + 6(a + 4) + 8

h(a+4) = a^2 + 8a + 16 + 6a + 24 + 8

h(a+4) = a^2 + 14a + 48

f[h(a+4)]

f(x) = 5x

Thus

f(h(a+4)) = f(a^2+14a+48) = 5(a^2 + 14a + 48) = 5a^2 + 70a + 240

The correct answer is given by option C.

Starting at 100% I have 82 clients 2 of them didn't get a check up what percent does that leave us at ?
murzikaleks [220]

82 total clients

2 did NOT get a checkup

(82 - 2) = 80 clients DID get a checkup

80/82 = 0.97561 = <em>97.561%</em> of your clients have had their checkup.

Interestingly, that's the exact same percentage of your clients who have had lunch.  Perhaps ... I'm not stating this as a fact, but it's a hunch ... just maybe the other two have not had their checkups yet because they are out getting lunch.
