Answer:
0.25feet
Step-by-step explanation:
The equation is not well written. Let the equation of the height be modelled as;
h = -16d²+8d+4
The velocity of the ball is zero at its maximum height.
Velocity = change in displacement/time
v = dh/dd
Differentiate
v = -32d+8
Since dh/dd = v = 0
0 = -32d+8
Add 32d to both sides
0+32d = 8
32d = 8
Divide both sides by 32
32d/32 = 8/32
d = 1/4
d = 0.25feet
Hence the maximum height of the tennis ball is 0.25feet
Note that the modeled equation was assumed. You can apply the same calculation to any equation given
Answer:
IT IS 5
Step-by-step explanation:
Do you have a picture of the proof? No one can answer it without seeing the shape and angles and such.
Well to find the total sales you must substitute for the variable in the equation;
t = 68.95b
t = 68.95(31)
t = 2,137.45
So the total of the store's boot sales is;
$2,137.45
-12 is a rational number, an integer, a real number, and a whole number.
