So, to start, circumference=pi*diameter. Diameter is 2*radius, or in this case, 5. So we have circumference=pi*10. So, in terms of pi, it is 10pi.
Answer:
- 2x² - 2x + 82
Step-by-step explanation:
(f - g)(x) = f(x) - g(x) , then
f(x) - g(x)
= 2 - x² - (x² + 2x - 80) ← distribute parenthesis by - 1
= 2 - x² - x² - 2x + 80 ← collect like terms
= - 2x² - 2x + 82
Answer:
A.
Step-by-step explanation:
Answer:
3) -11
Step-by-step explanation:
f(-3)=5*(-3)+4
f(-3)=(-15)+4
f(-3)=-11
<span>Commutative postulate for addition is Illustrated for the real numbers 3 + 2 = 2 + 3. Commutative Law of Additi): If a and b are in N, then a + b = b + a. An operation is commutative if you can change the order of the numbers involved without changing the result. Addition and multiplication are both commutative</span>
