chubhunter [2.5K]4 years ago
7 0

Answer:

The correct answer is 1/49

Step-by-step explanation:

In order to find this, we first can eliminate the negative in the exponent by putting the whole this in the denominator.

(-7)^-2 = 1/(-7)^2

Now we can evaluate the denominator

1/(-7)^2 = 1/49

Given the functions:<br> g(n) = 3n - 5<br> f(n) = n2 + 50<br> Find:<br> (g+f)(8)
puteri [66]

Answer:

(g + f)(8) =133

Step-by-step explanation:

Given

g(n) = 3n - 5

f(n) = n^2 + 50

Required

(g + f)(8)

This is calculated as:

(g + f)(n) =g(n) + f(n)

So, we have:

(g + f)(n) =3n - 5 + n^2  +50

Substitute 8 for n

(g + f)(8) =3*8 - 5 + 8^2  +50

(g + f)(8) =24 - 5 + 64  +50

(g + f)(8) =133
