Answer:
6sqrt2(cos(-5pie/4)+isin(-5pie/5))
Step-by-step explanation:
Multiply the two values together to get 45 * 3/5 = 135/5 = 27
Answer:
f(-1) = 2
Step-by-step explanation:
To evaluate this function at x = -1, replace "x" in the equation with (-1) (you should use the parentheses as indicated here).
f(x)=x²-3x-2 becomes
f(-1)=(-1)² - 3(-1) -2, or
f(-1) = 1 + 3 - 2, or
f(-1) = 2
