Answer:
x = 21
Step-by-step explanation:
Based on the inscribed angle theorem, we would have:
120° = 2(3x - 3)°
Solve for x
120 = 2*3x - 2*3
120 = 6x - 6
Add 6 to both sides
120 + 6 = 6x
126 = 6x
Divide both sides by 6
126/6 = x
21 = x
x = 21
Factoring, you have
h(t) = -16(t^2 -2 -8) = -16(t -4)(t +2)
The ball hits the ground when h(t) = 0, so
0 = -16(t -4)(t +2)
t = 4 or -2
The positive solution is the one of interest.
It will take 4 seconds for the ball to hit the ground.
Answer:
y = x - 5
Step-by-step explanation:
Given the equation
y = x + ?
We are being asked what value is added to x to give y
Consider the table, that is
x = 1 → y = - 4
x = 2 → y = - 3
x = 3 → y = - 2
x = 4 → y = - 1
x = 5 → y = 0
x = 6 → y = 1
In each case 5 is being subtracted from x to obtain y, that is
y = x - 5 ← equation relating x and y
I’m not sure but I’m commenting Bc I really need an answer I’m so sorry
