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)

Find the values of x and y
Anastasy [175]

Answer:

X=20

Y=70

Step-by-step explanation:

All angles within a triangle add up to 180

180 - 40 = 140

140 is the top angle of the big triangle

140 + x + x = 180

x = 20

Now use x to find y by subtracting from the right angle (90 degrees)

90 - 20 = 70

70 + 40 + y = 180

Y = 70
