Step-by-step explanation:
Answer:
9/1 *7/10 = 63/10 =6 3/10
Step-by-step explanation:
If the roots are 3, 2 and -3 then the function is created by multiplying
(x-3) * (x-2) * (x+3)
x^2 -5x +6 * (x+3)
x^3 -5x^2 +6x + 3x^2 -15x +18 = 0
x^3 -2x^2 -9x +18 = 0
Answer:
x ≈ 49.5°
Step-by-step explanation:
We use cos∅ to solve this:
cosx = 13/20
x = 
x = 49.4584
