Answer:
The ball first bounces up to a height of 2 meters, and then falls 2 meters towards the ground
Step-by-step explanation:
Roots: - √5 , √5, and - 3
=> these are factors of the polynomial: (x + √5), (x - √5), and (x + 3).
Multiply those three factors:
(x + √5) (x - √5) ( x + 3) = [x^2 - 5] ( x + 3 ) = x^2 + 3x^2 - 5x - 15
Therefore the polynomial x^2 + 3x^2 - 5x - 15 is a polynomial with the given roots.
Answer: option B. x^3 + 3x^2 - 5x - 15
Answer:
Step-by-step explanation:
<u>Given:</u>
- Horizontal leg of the right triangle = 778 ft
- Angle opposite to vertical length = 39°
- Vertical leg = h
<u>Use tangent to solve for h:</u>
- h/778 = tan 39°
- h / 778 = 0.81
- h = 0.81*778
- h = 630.18
Correct choice is B
Answer:
your answer is 1/10. hope this helps!
