Answer:
Step-by-step explanation:
Both angles together equal 180. Set up your formula as
-4x+5+-13x+39 = 180
Now move your terms to have all x values on one side
-4x-13x = 180-5-39
-17x = 136
x=136 / -17
Use this answer in place of your x in each equation to get the angle.
You got this!
3.25 would Raquel to 47 so 20
Your slope of this graph is: 4/3x

Step-by-step explanation:
1. h₀ = 70
v₀ = 0 since the rock is dropped it has no initial velocity
when the rock hits the ground the height = 0
plug into the formula
0 = -4.9t² + 0(t) + 70
0 = -4.9t² + 70
Add 4.9t² to both sides
4.9t² = 70
Divide both sides by 4.9
t² = 14.2857142857
Take the square root of both sides
t = 3.7796447301
t ≈ 3.8 seconds
