Helpppppp me pleaseeeeeee!!!!!!!!
Nimfa-mama [501]

Answer:

Step-by-step explanation:

think of the flight of a small rocket..  what does it seem like the parabola would look like?  down means it looks like a cup or glass , upside down , up mean a cup or glass right side up.

when t = 0  the rocket is at 25, so that's the initial height

it's velocity is initially 200 m/s

put equation from std. form to vertex form

y = ax^{2} + bx +c       =>       y = a(x - h ) ^2 + k

h = -4.9t^{2} + 200t + 25  =>h = -4.9(t - 20.41)^2 + 2,065.82

(h,k) =  (20.41 , 2065.82)

Half of sarans wire is equal to 2/5 of daniel's. chris has 3 times as much as sarah. in all, their wire is 6 feet. how long is s
Pepsi [2]
You need to make a series of equations from what you are given first. I am going to use the first letter of each of the names to represent the length of that persons wire.
1/2s=2/5d
3c=s
s+d+c=6 ft

Okay. Now you can combine the first two equations knowing what s equals:
1/2(3c)=2/5d
d=15c/4

Now you have d=15c/4 and s=3c, so you can replace d and s in the third equation.

3c+15c/4+c=6

Then solve for c and plug it into the equation 3c=s to find the length of sarah's wire.
