The volume of a rectangular prism is 420 cubic centimeters. The length, L, is 6 centimeters and the width, W, is 14 centimeters.
Harman [31]

Answer:

5 centimeters

Step-by-step explanation:

We know the equation to find volume is V = B x h, where B is the base of the prism. (It is also known as the simple V = l x w x h.)

No matter what equation you use, you will end up with V = l x w x h, since the base of a rectangular prism is length x width. So, we're going to plug in our known information to get 420 = 6 x 14 x h.

Then, we're going to multiply 6 x 14 to get 84. Now we have 420 = 84 x h. To isolate the h (in order to find what it is), we must divide both sides by 84.

420/84  = 5, so whats left of the equation is 5 = h, meaning your height is 5 centimeters.

An ellipse has a vertex at (4,0), a co-vertex at (0,3), and a center at the origin. Which is the equation of the ellipse in stan
bekas [8.4K]

ANSWER

\frac{ {x}^{2} }{ 16}  + \frac{ {y}^{2} }{ 9}   = 1

EXPLANATION

The given ellipse has a vertex at (4,0), a co-vertex at (0,3), and a center at the origin.

The equation of an ellipse with vertices on the x-axis and center at the origin is:

\frac{ {x}^{2} }{ {a}^{2} }  + \frac{ {y}^{2} }{ {b}^{2} }   = 1

The ellipse has vertex at (4,0) , hence a=4.

Also the co-vertex is at (0,3) , b=3

We substitute the values into the equation to get:

\frac{ {x}^{2} }{ {4}^{2} }  + \frac{ {y}^{2} }{ {3}^{2} }   = 1

\frac{ {x}^{2} }{ 16}  + \frac{ {y}^{2} }{ 9}   = 1
