To round the answer u need to see if the ending number on the right is above or below 5 if it’s 5 or above then you make the number behind it go up(8–>9) and if it’s below 5(4 and lower) then that stays the same

How do I find the area of the shaded blue region?

kogti [31]

That's a 240 degree sector of a 9 inch radius circle. The whole circle has area πr² and we want 240/360 of it.

A = (240/360) π (9²) = 54 π

Answer: 54 π square inches

That's the exact answer. An approximation is

169.646 square inches

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:

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

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