H (t) = - 16t ^ 2 + 16t + 480
For this case, the first thing to do is to match the polynomial to zero to find the roots.
We have then:
0 = -16t ^ 2 + 16t + 480
From here, we obtain the following roots of the polynomial:
t1 = -5
t2 = 6
We ignore the negative root because the time is always greater than zero.

Answer:
Marian can order 1,771 combinations
Step-by-step explanation:
In this question, we are interested in calculating the number of combinations Marian can order given that there are 23 flavors that can be served in three ways.
Mathematically, the number of combinations that can be ordered is simply 23C3
This is equal to 23!/(23-3)!3! = 23!/20!3! = 1,771
The number of combinations she can order is thus 1,771 combinations

Answer:
y=-2/3x+7
Step-by-step explanation:
Since you know the path is parallel to the equation y+-2/3x+12, you already know the slope is -2/3.
It says y is the height above street level, so that is 3. The problem says x is time, which is 6, so all you have to solve for is the y intercept.
3 (y, or the height above street level) = (-2/3) 6 (x, or time) + b (unknown y intercept)
3 = -4 + b
7 = b
So, y = -2/3x + 7
