The table shows your height on a water slide at various time intervals
Allushta [10]

1. The average rate of change in a riders height between 1 and 3 seconds -30 ft/s

2. The average rate of change in a riders height between 0 and 5 seconds -24 ft/s

3. Another word for rate of change in this situation is speed

<h3>What is speed? </h3>

Speed is defined as the rate of change of the distance travelled with time. Mathematically, it can be expressed as:

Speed = distance / time

With the above idea, we can obtain the answers to the question given above.

<h3>1. How to determine the rate of change between 1 and 3 seconds</h3>
  • Change in height = 30 - 90 = -60 ft
  • Change in time = 3 - 1 = 2 s
  • Rate of change =?

Rate = Change in height / change in time

Rate = -60 / 2

Rate = -30 ft/s

<h3>2. How to determine the rate of change between 0 and 5 seconds</h3>
  • Change in height = 0 - 120 = -120 ft
  • Change in time = 5 - 0 = 5 s
  • Rate of change =?

Rate = Change in height / change in time

Rate = -120 / 5

Rate = -24 ft/s

<h3>3. what is another word for rate of change?</h3>

From the definition of speed given above, we can say that: another word for rate of change is speed

Christine, Kareem, and Trey have a total of $133 in their wallets. Kareem has $5 more than Christine. Trey has 4 times
Nadusha1986 [10]

Answer:

Christine has $18, Kareem has $23, and Trey has $92.

Step-by-step explanation:

This can be solved by using variables to represent the unkown values.

x = Christine's money

x + 5 = Kareem's money.

4(x + 5) = Trey's money.

x + (x + 5) + 4(x + 5) = 133

2x + 5 + 4x + 20 = 133

6x = 108

x = $18

This means that Christine has $18, Kareem has $23, and Trey has $92.

Hope this helps

A city that had 40,000 trees started losing them at a rate of 10 percent per year because of urbanization.
goblinko [34]

Answer:

t = 13.1576  years

Step-by-step explanation:

The situation can be modeled as

P = Po.(1-r)^t

Where

t is the years transcurred

Po is the initial amount

r is the rate of change

Po = 40000

r = 10% equivalent to 0.1

Now

A quarter of the original amount

(1/4)*Po = Po.(1-r)^t

(1/4) = (0.9)^t

t = 13.1576
