When a ball is dropped onto a flat floor, it bounces to 65% of the height from which it was dropped. If the ball is dropped from

valkas [14]

Using a geometric sequence, it is found that:

The rule for the height of the nth bounce is:

$a_n = 52(0.65)^{n-1}$

The height of the fifth bounce is of 9.28 cm.

In a <em>geometric sequence</em>, the quotient between consecutive terms is always the same, called common ratio q.

The nth term of a geometric sequence is given by:

$a_n = a_1q^{n-1}$

In which $a_1$ is the first term.

In this problem:

Bounces to 65% of the height from which it was dropped, thus the common ratio is of $q = 0.65$ .
Dropped from 80 cm, thus, the height of the first bounce is $a_1 = 80(0.65) = 52$ .

Thus, the rule for the height of the nth bounce is:

$a_n = 52(0.65)^{n-1}$

The height of the fifth bounce is $a_5$ , thus:

$a_5 = 52(0.65)^{5-1} = 9.28$

The height of the fifth bounce is of 9.28 cm.

Amy drives 300 miles from London to Newcastle.

WARRIOR [948]

Amy's average speed during her whole journey from London to Newcastle (300 miles) was 51.422 miles per hour.

<h3>How to calculate the average speed?</h3>

This is calculated by taking the total distance and dividing it into the total time.

<h3>What was Amy's average speed?</h3>

First part of ther journey: 165 miles at 60mph, which is equal to 2.75 hours

Time: distance/speed
Time: 165 miles/ 60 mph= 2.75 hours

Second part of her journey: 135 miles in 3.083 hours (3 hours and 5 minutes)

Total distance: 300 miles
Total time: 2.75 hours + 3.084 = 5.834

Average speed: 300 miles / 5.834 = 51.422 miles per hour

Bobby describes two lines to Frank, telling him that beginning at point A, line #1 goes up 3 units and to the right 8 units, whi

rodikova [14]

When a line changes position from one point to another, the movement is referred to as transition.

<em>Bobby does not have enough information to make a valid conclusion.</em>

The movements of the lines are given as:

<em>Line 1: 3 units up and 8 units right</em>

<em>Line 2: 8 units down and 3 units right</em>

The given information only describes the movement of both lines, but does not give details about the initial relationship between the lines.

<em>Hence, no valid conclusion can be made with the given information.</em>
