For this, I will be factoring by grouping to solve for y.
Firstly, factor y^3 + 5y^2 and -9y - 45 separately, Make sure that they have the same quantity on the inside:
Now you can rewrite it as . However we are not finished factoring.
Now with y^2 - 9, we will apply the difference of squares rule, which is . Apply it as such:
Now that it is completely factored, we can apply the Zero Product Property and solve for y:
<u>In short, y = -5, -3, and 3.</u>
The first one is the answer
h(t) = -16t2 + 64
Time to reach ground:
h(t) = 0
-16t2 + 64 = 0
Solve for t, keeping only the positive solution.
Time to fall 36 ft:
Since it is dropped from 64 ft, its height after falling 36 feet is 64-36=28 ft.
28 = -16t2 + 64
-16t2 + 36 = 0
Answer:
y = 6<em>x</em><em> </em>^2 <em>-</em> 6<em>x</em><em> </em>+ 9

If the net can be folded into triangular pier amid's, the shapes that would appear in the nuts are all triangles. There would be a total of four triangles. One triangular base, and three triangular lateral faces.
