Cosine functions are positive in quadrant 4
Here is a helpful mnemonic All Students Take Calculus (might be helpful in the future)
f(x) = x + 3
when x = 0, f(x) = 3
when x = 1, f(x) = 1 + 3 = 4
when x = 2, f(x) = 2 + 3 = 5
when x = 3, f(x) = 3 + 3 = 6
answer is D
f(x) = x + 3
6= 2D/5
5 x 6 = 30
30/2D
15=D
Answer:
Your answer would be 60
Step-by-step explanation:
=36(6 - 4) 6(6 – 8)
= 36(2) + 6 (-2)
= 72 + (-12)
= 72 - 12
= 60
hope it helps!
