Answer:

Step-by-step explanation:

Following the order of operations as set out in PEMDAS

6² - 36 ÷ 3² × 4 - 18 ( no parenthesis so evaluate exponents )

= 36 - 36 ÷ 9 × 4 - 18 ( multiplication/ division, evaluate from left to right )

melamori03 [73]

Answer:

D. 32

Step-by-step explanation:

For this problem, we simply plug -9 in for x in f(x):

f(x)=\frac{1}{3} x^2+5  ⇒  f(9)=\frac{1}{3} *(9^2)+5=\frac{1}{3} *81+5=27+5=32

Thus, the answer is D. 32.

Hope this helps!
