A jet plane is descending at a rate of 200 feet per second from an altitude of 36000 feet. Let x represent the number of seconds of descent and y represent the jet plane's altitude in feet. Which equation represents this situation?

if you need just tell me and i will come to the rescue.

step-by-step explanation:

$6.42

step-by-step explanation:

x = 3 ± √(5+y)

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
