David drops a ball from the top of a building with a height of 64 feet.

Mathematics

Answer:

Step-by-step explanation:

The position formula for this is actually

s(t)=-16t^2+64

It says, in not so may words, that the object was dropped under the influence of gravity from a height of 64 feet. When it hits, the ground, it will not be above ground at all anymore...it will be ON the ground and have a height of 0. Therefore, if we set the position function equal to 0 and solve for t, we are finding out how long it will take for the object to hit the ground.

0=-16t^2+64 and

16t^2=64 and

t^2=4 and

t = 2

It takes 2 seconds for the object to hit the ground from 64 feet up.

Students in a class were asked to name their favorite sport they like to watch on television. How many more time students want t
levacccp [35]
First, we need to add up all the percentages to make sure we have 100%.

25.5% + 0.03% = 25.53%

This means that 74.47% of the students chose something other than basketball or soccer.

The amount of students you stated there were was 2553.

25.5% of 2553 is 651 students and

0.03% is 8 students.

Now, we divide 651 by 8 to determine the amount of times over basketball was chosen.

651 ÷ 8 = 81

Basketball was chosen 81 times over again compared to soccer.

To find how much more times basketball was chosen, subtract 8 from 651

651 - 8 = 643

Basketball was chosen 643 times more than soccer.
