the ellipse is centered at the origin, has axes of lengths 8 and 4, its major axis is horizontal. how do you write an equation for this ellipse?

The equation for this ellipse is .

Step-by-step explanation:

The standard equation of the ellipse is described by the following expression:

Where and are the horizontal and vertical semi-axes, respectively. Given that major semi-axis is horizontal, . Then, the equation for this ellipse is written in this way: (a = 8, b = 4)

The equation for this ellipse is .

yes

step-by-step explanation:

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to

have a nice day!
