Answer:
100ft I'm not completely sure but
Step-by-step explanaon 5x5=25 2x2=4 25x4=100
Answer:
x = 63
Step-by-step explanation:
It's Quadrilateral so:
360-90-72= x + x +22 (Cause that 2 triangle is isosceles)
2x=126
x=63
Answer:

<em></em>
Step-by-step explanation:
Given
Where:
Required
The height
The volume is calculated as:
This gives:
Rewrite as:
So, we have:
Take cube roots
![h = \sqrt[3]{455cm^3}](https://tex.z-dn.net/?f=h%20%3D%20%5Csqrt%5B3%5D%7B455cm%5E3%7D)
<em></em><em> --- approximated</em>
Use the equation
t = -b / (2a)
where:
a = -16
b = 30.4
Plug these values into the equation.
b)
Evaluate h(t) at the time of maximum height. The time of maximum height is the value found in previous part.
c)
Set h(t) equal to 3 and solve for t.
3 = -16t2 + 30.4t + 5
0 = -16t2 + 30.4t + 2
Solve this quadratic equation for t. I suggest you use the quadratic formula to solve for.
