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.

answer: the value of x is 7cm

step-by-step explanation:

the answer is d. (1.2, -4.7) on edgn

hope this !

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
