HELP PLS MAT WORD PROBLEM Sarah Learning learning to do extreme snowboarding. One of her jumps on a snowboard could be described using the function y= -0.4x^2 + 1.4x +3, where y is the height above her landing surface in metres and x is the horizontal distance from her takeoff point.

A- calculate the discriminant. What does the discriminant indicate about the function?

B- use the quadratic formula to calculate the roots of the function.

if im undersanding the question correctly, its organized from 10

step-by-step explanation:

72 is the answer to this problem

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

sine
