Answer:
Look below
Step-by-step explanation:
(a) The area of a triangle is:
The height of this triangle is h and it's base is 4+h so...
![A=\frac{1}{2}*[h*(h+4)]](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7D%2A%5Bh%2A%28h%2B4%29%5D)
(b) If the height is 8 cm, then the base is 4+8 which is 12 cm so...
Ok ima try
a x 3 + c x 2 = 14
This is how I learned please don’t roast me if I do it wrong

Step-by-step explanation:
Diagram C shows the inverse of P(x).
<span>a)
Acceleration of stone = 10
Integrate:
So velocity = 10t
Integrate again:
So distance from starting point = 5t^2
Distance from ground = 450-5t^2
b)
450 - 5t^2 = 0
9.48 seconds
c) velocity = 10t
Put the time into this to give:
94.8 m/s
d.
Velocity = 10t + 5
Integrate again:
5t^2 + 5t
Solve
5t^2 + 5t = 450
Gives 9 seconds</span>
