1 meter is 100 centimeter, as "centi" means 1 hundredth:
So 100 centimeter means 100-"1 hundredth" meters, which is 1 meter.
In short, since 1 meter is 100 centimeters, 8 meters are 800 centimeters.
Answer: 800 cm

Answer:
Step-by-step explanation:
In the equation, 72t represents the initial upwards velocity and 5 represents the initial launching height. The leading term represents the pull of gravity on the object in the English system of measurement.
So the first question says the initial height is 5 feet. TRUE
The second question says the initial vertical velocity is -72. FALSE (it's positive 72 ft/sec)
The third question says that the object will hit the ground after approximately 4.57 seconds. TRUE. Find this by setting the h(t) on the left equal to 0, since this is the height at any time during the flight. When h(t) = 0, that means that there is NO height, which means the object is on the ground. Set the equation equal to 0 and factor to find t. Putting that into the quadratic formula gives you t values of -.068 and 4.57. Since the 2 things in math that will NEVER EVER be negative are distances and time, we can safely disregard the negative t value and go with t = 4.57.
The fourth question says that after t = 3 seconds, the object is 173 feet high. FALSE. Find this by subbing in a 3 for every t in the equation.

This gives you that h(3) = 77 feet
The last question says that at t = 0, h(t) = 0. FALSE again. Sub in a 0 for every t in the equation, and you get h(0) = 5, which is the initial launching height.
