A ball is dropped from a height of 10 meters. Each time it bounces, it reaches 50% of its previous height. The total vertical distance down the ball has traveled when it hits the the 5th time is how many meters

28.75 m.

Step-by-step explanation:

It is given that a  ball is dropped from a height of 10 meters. Each time it bounces, it reaches 50% of its previous height. So,

For first bounce the vertical distance

For next bounce ball has to travel up and down by 50% of previous distance, i.e., 10 m.

For second bounce the vertical distance

Similarly,

For third bounce the vertical distance

For fourth bounce the vertical distance

For fifth bounce the vertical distance

The total vertical distance down the ball has traveled when it hits the the 5th time is

Therefore, the total vertical distance  down the ball has traveled when it hits the the 5th time is 28.75 m.

step-by-step explanation:

which of the following statements correctly describes the expression below based on its degree and number of terms?

314 - 7x2 + 11

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
