Answer:
A
m less than or equal to 19
She can buy at most 19
Step-by-step explanation:
25 divided by 1.29 is 19.379844... but you can't buy fractions of a music song.
So the closest to the maximum would be 19.
We can create a parabola equation of the trajectory using
the vertex form:
y = a (x – h)^2 + k
The center is at h and k, where h and k are the points at
the maximum height so:
h = 250
k = 120
Therefore:
y = a (x – 250)^2
+ 120
At the initial point, x = 0, y = 0, so we can solve for
a:
0 = a (0 – 250)^2 + 120
0 = a (62,500) + 120
a = -0.00192
So the whole equation is:
y = -0.00192 (x – 250)^2 + 120
So find for y when the golf ball is above the tree, x =
400:
y = -0.00192 (400 - 250)^2 + 120
y = 76.8 ft
So the ball cleared the tree by:
76.8 ft – 60 ft = 16.8 ft
Answer:
16.8 ft
Answer:
40
Step-by-step explanation:
20 + 2.5x = 3x
20 = 0.5x
x = 40
Hey there!
First, we should subtract them.
90125 - 58478 = 31,647
90125 is 31647 more than 58478.
Hope this helps!
Have a great day!
