Answer: answer is 72 you can get it by either multiplying the height and the base by two and following the formula for area of a triangle or you can divide 36 by two and multiply that by 4
Step-by-step explanation:
Question:
Solution:
Consider the following two functions:

and

Now, consider the following definition:

thus, we get:

this is equivalent to:

this is equivalent to:

So that, we can conclude that the correct answer is:
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.
