Answer:
r^9/r^3 = r^9-3 = r^6
Step-by-step explanation:
Then it holds 8 gallons.
Comment the rest of the answer if you want. Thanks!
Recall that the volume of a regular prism is given by the area of the base times the height.
Given that the base of the prism is a regular pentagon with an apothem of 2.8 centimeters.
The pentagon consist of 5 isosceles triangles with the apothem as the height and the side of the pentagon as the base.
Recall that the are of a triangle is given by 1/2 base times height.
Thus the area of of the pentagon base of the prism is given by

Therefore, the volume of the prism is given by
Axis of symmetry shows the min/max. its a max in this case and its at t=1.5
so the ans is <span>t = 1.5; it takes 1.5 seconds to reach the maximum height and 1.5 seconds to fall back to the ground</span>
Answer:
cos6x.
Step-by-step explanation:
We use the identity
cosAcosB - sinAsinB = cos(A+B)
so cos5xcosx - sin5xsinx = cos(5x + x)
= cos6x.
