Gan arch has the shape of a semi-ellipse. the arch has a height of 8 feet and a span of 20 feet. find an equation for the ellipse and use it to find the height, in feet, of the arch at a distance of 5 feet from the center. (round your answer to the nearest hundredth if necessary.)

i can tell you jamal now has 3 cookies xd

tommy has 2.

this made me lol.

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
