Sinθ = 16/20 = 0.8
θ = arcsin(0.8) ≅ 53°

Use ^2 to represent ².
Pythagorean identity:
sin²(x) + cos²(x) = 1
Answer:
x = 32
Step-by-step explanation:
-9 = x - 41
41 + (-9) = x -41 + 41
32 = x
Answer:
πx² -6πx + 9π
or
π(x² - 6x + 9)
Step-by-step explanation:
area = πr² = π(x-3)² = π(x² - 6x + 9) = πx² - 6πx + 9π
I know the parabola will open downward because the leading coefficient of the equation, being -5, is negative/less than zero.
Using the graphing you graph the two equations and then find the point where the two lines of the equation meet.
Hope this helps :)
