Answer:
45.05 seconds
Step-by-step explanation:
Use the formula: d = v
t + 
a
d = distance v = initial velocity (m/s)
t = time (s) a = acceleration (m/
)
m is meters and s is seconds. They are units of measurement so leave them be.
Assuming the object is simply dropped, the initial velocity is 0 since the object was not moving before it was dropped.
The distance is 725 feet, which is 220.98 meters.
The acceleration is 9.81m/ since that is the acceleration of Earth's gravity, aka free fall.
Time is what we are trying to find so just leave it as the variable t.
So plug the values into the equation:
220.98m = (0)(t) + (9.81m/)(t)
220.98m = (4.905m/)(t)
45.0519877676s = t
t = 45.05s
Remember to pay attention to units because your answer will be wrong otherwise
It’s like -5 or something maybe
Answer:
The volume of a cylinder:
Step-by-step explanation:
-To find the volume of a cylinder, you first need the formula:
diameter
height
-Use the following diameter and height for the formula:
-Then, you solve:
-Since the hundredth place is 2, It cannot be rounded to the nearest hundredths place, so it would be:
Answer: 175
Step-by-step explanation: I hope this helps!!
None of your answers above will answer the question. The proper value for x = 1/2 is 7/4. The work for this is below.
f(x) = 3x^2 + 1
f(1/2) = 3(1/2)^2 + 1
f(1/2) = 3(1/4) + 1
f(1/2) = 3/4 + 1
f(1/2) = 7/4
I assume you may have missed something in typing, but 7/4 would be your answer.
