H(t)=-0.2t^2+2t models the height in feet of a ball that is kicked into the air where t is given as time, in seconds. After how
Marizza181 [45]
To get the maximum height, we first determine the time at which this maximum height is attained by differentiating the given equation and equating the differential to zero.
                                 h(t) = -0.2t² + 2t
Differentiating,
                               dh(t) = -(0.2)(2)t + 2 = 0
The value of t is equal to 5. Substituting this time to the original equation,
                                   h(t) = -0.2(5²) + 2(5) = 5 ft
Thus, the maximum height is 5 ft and since it will take 5 seconds for it to reach the maximum height, the total time for it to reach the ground is 10 seconds.

Answers:              maximum height = 5 ft
                 time to reach max height = 5 seconds
            time it will reach the ground = 10 s

HELP ME OUT PLEASE I RLLY NEED IT ASAP. ):
LenaWriter [7]

(a) Slope is rise over run, or change in y over change in x.

1 -> 3 ( \frac{y_{2}-y_{1}}{x_{2}-x_{1}} = \frac{4 - -8}{-1 - -5} = \frac{4 + 8}{-1 +5}= \frac{12}{4} =\frac{12}{4} )

2 -> 3 ( \frac{y_{2}-y_{1}}{x_{2}-x_{1}} = \frac{1 - 7}{0 - 2} = \frac{-6}{- 2} =\frac{6}{2} )

3 -> -1/3 ( \frac{y_{2}-y_{1}}{x_{2}-x_{1}} = \frac{-7 - -3}{6 - -6}= \frac{-7+3}{6+6}=\frac{-4}{12}=-\frac{1}{3} )

(b) If a line is parallel, the slopes will be the same. If they are perpendicular, the slopes will be are negative reciprocals of one another. If they are neither, then their slopes don't match up in any way.

1 & 2 -> Parallel

1 & 3 -> Perpendicular

2 & 3 -> Perpendicular

     Note - Since 1 & 2 are parallel, then both 1 and 2 will be perpendicular to 3!

Have a nice day!

     If this is not what you are looking for - comment! I will edit and update my answer accordingly. (ノ^∇^)

PLZ HELPPPP I CAN'T FAIL THIS
Shtirlitz [24]

Answer:

both Jenna and Mia got the same answer because the answer they got is correct but they used their own techniques to reach for the answer.

Mia's steps are time efficient enough by shortening the length of the sum and jumping steps...

Jenna is also correct in her own way, she wrote the full steps and explanation of the answer stepwise which is time consuming but cannot be wrong at the end throughout the steps. Even if she gets wrong she can quickly find the place of the mistake.
