Suppose a car left a skid mark d feet long. the formulas will estimate the speed s in miles per hour at which the car was traveling when the brakes were applied. use the formulas to complete the table. round to the nearest tenth of a mile per hour. dry road formula: s=√27d wet road formula s=√13.5d skid mark length 60 feet dry road1 = wet road1 = 120 feet dry road2 = wet road2 =

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)
