a woodland jumping mouse hops along the ground along a parabolic path that can be modeled by the following equation: y = −0.2x2+1.3x (where x is the horizontal position in feet and y is the height in feet). what is the maximum height the mouse can jump?

 2.1125 feet

Step-by-step explanation:

the vertex will be the maximum value of this parabola.  

the general form for a quadratic equation is:  ax² + bx + c, for this equation,

a = -0.2, b = 1.3, and c = 0

find the vertex by first using the formula x = -b/(2a)

x = -1.3/(2*-0.2)

  x = -1.3/-0.4

    x = 3.25

Now plug in that x value to find the actual maximum height

y = -0.2(3.25)² + 1.3(3.25)

    y = -0.2(10.5625) + 4.225

          y = -2.1125 + 4.225

                  y = 2.1125 feet

answer: 2/4

step-by-step explanation:

the answer is (-4,-4)

hope this ! : d
