Answer:
f(2) = f(3) = 102 ft
Step-by-step explanation:
The height f at t = 2 seconds is given by:
The height f at t = 3 seconds is given by:
For both t =2 and t =3, the expression results in a height of 102 ft, therefore f(2) = f(3) = 102 ft.
The answer to this question is p+3
Answer:
speed = distance / time
At 96miles in 2 hours
the speed = 96miles/ 2hours = 48miles per hour
at 5 hours, Distance = speed x time
distance = 48 x 5 = 240miles
Step-by-step explanation:
step 1 : determine the speed per hour
speed = distance / time
step 2 : after getting the speed of the car per hour, the distance cover in 5hours can now be determine using
distance = speed x time
Answer:
Step-by-step explanation:
The formula for the volume of a sphere is
In order to use this formula we have to have a value for the radius and right now we don't. But we can find it indirectly by using the circumference formula. The circumference formula is
If the circumference is 20π, then we will fill that in for "C" and solve for r:
20π = 2πr and if you divide both sides by 2π, you'll get that r = 10. Now we have a radius.
Using that in the volume formula:
and then simplifying a bit:
and
which divides to give you
, third choice down.
