Suppose a golf ball is driven so that it travels a distance of 400 feet as measured along the ground and reaches an altitude of 300 feet. if the origin represents the tee and is the ball travels along a parabolic path over the positive x-axis, find an equation for the path of the golf ball. which form does the equation fit?

y = [ -3 /400 ] ( x - 200 )^2 + 300

Explanation:

Suppose a golf ball is driven so that it travels a distance of 400 feet as measured along the ground and reaches an altitude of 300 feet. If the origin represents the tee and is the ball travels along a parabolic path over the positive x-axis, find an equation for the path of the golf ball. Which form does the equation fit?

The given question tells us that our vertex is point (h,k), where h is the midpoint of the given horizontal i.e. 400/2 = 200, thus h=200 (horizontal) and k=300 (vertical). So we know we have two zeros with one x at 0 and x at 400.

from the equation of a parabola

y = a ( x - h )^2 + k. substituting the  values and solving to obtain a we have.

y = a (x - 200)^2 + 300

make a the subject of the equation

a = [ y-300 ] / [ ( x - 200)^2 ].

Now for y=0, x =400, thus we have\

a = [ 0 - 300 ] / ( 400 - 200 ) ^2, therefore

a = ( -300 ) / (200^2),

since

a = - 3 / 400.

So finally we have our equation reading as

y = [ -3 /400 ] ( x - 200 )^2 + 300.

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

i dont think you are wrong for wanting to get even with someone who did you wrong.

(i'm an eye for an eye kind of person) but if this person hurt you in a sexual way, i dont suggest doing anything to him. he should be taken to the proper authorities, you could go to jail depending on what you do. if it was something small like your sibling took your spot on the couch, than yea, i would get even with him by taking one of his favorite snacks lol. but i dont suggest you doing anything illegal.
