Tom throws a ball into the air. the ball travels on a parabolic path represented by the equation h = -8t 2 + 40t, where h represents the height of the ball above the ground and t represents the time in seconds. the maximum value achieved by the function is represented by the vertex. use factoring to answer the following:

how many seconds does it take the ball to reach its highest point?

what ordered pair represents the highest point that the ball reaches as it travels through the air?

hint: because parabolas are symmetric, the vertex of a parabola is halfway between the zeroes of the quadratic.

Time to highest point: 5/2, or 2.5 seconds

Ordered pair: (5/2, 50)

Step-by-step explanation:

Find the vertex of h(t). This will be the highest point of the ball

Find the x coordinate of the vertex with the formula: x = -b/(2a)

x = -40/[2(-8)] = -40/-16 = 5/2

to find the y value, plug 5/2 into the equation and solve

h(5/2) = -8(5/2)² + 40(5/2)

   h(5/2) = -8(25/4) + 200/2

          h(5/2) = -200/4 + 100

             h(5/2) = 50

So the ball reached a maximum height of 50 feet

i got a hair cut today from my mom not to flex just to flex kim jon un is one rad fellow i'd say you'd need to take the hairline in kinda like a box shape like someone rammed a lego brick into your head. from there you really need to take the top up keeping with that boxy aesthetic, finally coat the whole thing with gel if your country economics are failing or whatever you can just coat it with the starving children's food rations. about 5 orphans per strand is a good ratio. good luck with the fresh cut my dude
