The height h(t) , in feet, of a snowboarder t seconds after beginning a certain jump can be approximated by h(t) = -16t^2 +22.9t + 9. If the snowboarder lands at a point that is 4 feet below the base of the jump, determine the airtime (the time the snow boarder is in the air) for this jump. Round to the nearest tenth of a second.

65°

step-by-step explanation:

the total measure of a triangle is 180 degrees. 62 + 53 is 115.

180 - 115 = 65

step-by-step explanation:

where is the questions

51840000 cm 2

step-by-step explanation:

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)
