Answer:
1 seconds after being thrown, the stone reaches its max height
Step-by-step explanation:
The parabolic (quadratic) equation is:
Lets expand this in the form , so we have:
We can say the values of a,b, and c, now to be:
a = -5
b = 10
c = 40
The number of seconds at which the max would occur is given by the point, x, at:
We know a and b, let's find the seconds, x,
Hence,
1 seconds after being thrown, the stone reach its max height
Answer:
Total distance Jason cycled = 20 miles
Step-by-step explanation:
Distance covered in first 2 hours = 2( 7.5)
=15
Distance covered in the 3rd hour = 15/3
= 5
Dividing by 3 because the distance covered in the 3rd hour is 1/4 of the distance covered in first two hours. By dividing by 3 we will get 1/4 of the distance
Total Distance = Distance covered in first two hours
+ Distance covered in the 3rd hour
=15 + 5
Total Distance = 20
Digital Camera $983 + Printer $275 = $1258
$1258 / $10 = 125.8
So he must draw 126 ($10) = $1260
