The base of a circular fence with radius 10m is given by x =10cos t, y = 10sin t. The height of the fence

at position (x, y) is given by the function h(x, y) = 4 +0.01(x2 - y2). so the height varies from 3mto 5m.

Suppose that 1L of paint covers 100m2.

Sketch thefence and determine how much paint you will need if you paint bothsides of the fence.

step-by-step explanation:

distance formula is d=√(x2-x1)^2   +   (y2-y1)^2

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,
