A driver is 15 feet below the surface of the water 10 seconds after he entered the water and 90 feet below the surface after 40
spin [16.1K]

Answer:

\frac{-75ft}{30sec} or simplified would be \frac{-2.5ft}{sec}

Step-by-step explanation:

In order to calculate the rate of change, we must subtract his end position and end time by the starting position and starting time. We are using the -15 feet since it is below the surface area as the starting position and the 10 seconds as the starting time. We make each of these into a fraction and subtract like so...

\frac{-90ft - (-15ft)}{40sec - 10sec} = rate of change

\frac{-75ft}{30sec} = rate of change

\frac{-2.5ft}{sec} = rate of change

Therefore, we can see that the rate of change of the diver is \frac{-75ft}{30sec} or simplified would be \frac{-2.5ft}{sec}

zhenek [66]

Answer:

19 and 2

Step-by-step explanation:

Let x represent the first number and y represents second number

x + y = 19

x - y = 17 add two equations up

2x = 36 divide both sides by 2

x = 19 and since the difference is 17 the other number is 2
