Answer:
8 pi = 25.13
Step-by-step explanation:
The quadratic equation cannonball’s path if it was launched with the same velocity, but from the ground instead would be given by:

<h3>What is the quadratic equation for the height of a projectile?</h3>
Considering the gravity, it is modeled by:

In which:
is the initial velocity.
is the initial height.
For this problem, we want:
- The same initial velocity, hence
.
- Launched from the ground, hence
.
Then, the equation is:

Answer:
17
Step-by-step explanation:
Remark
In this formation, the chords cut each other so that
Equation
(3x - 1) * 3 = 12*(x -2) Remove the brackets.
Solution
9x - 3 = 12x - 24 Add 24 to both sides.
9x - 3 + 24 = 12x - 24 + 24 Combine
9x + 21 = 12x Subtract 9x from both sides
9x - 9x +21 = 12x - 9x
21 = 3x Divide by 3
21/2 = 3x/3
7 = x
Find QR
QR = 12 + x - 2
QR = 10 + 7
QR = 17
the first quadrant only has positive numbers therefore everything is positive
