Step-by-step explanation:
Answer:
8y
Step-by-step explanation:
4y(2) = (4 x 2)y = 8y
If sean and betty both did x each,
then 2x=8/9
x=(8/9)/2=4/9
The total elevation that the scuba driver does is from
![-29 \frac{7}{10}](https://tex.z-dn.net/?f=-29%20%5Cfrac%7B7%7D%7B10%7D%20)
to
![-28 \frac{9}{10}](https://tex.z-dn.net/?f=-28%20%5Cfrac%7B9%7D%7B10%7D%20)
The ascending distance =
![-28 \frac{9}{10}--29 \frac{7}{10}](https://tex.z-dn.net/?f=-28%20%5Cfrac%7B9%7D%7B10%7D--29%20%5Cfrac%7B7%7D%7B10%7D%20)
The ascending distance =
![\frac{4}{5} feet](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7B5%7D%20feet)
The time (t) taken during the ascend = 19.125 - 12.75 = 6.375 minutes
The average change in speed is given by the ascending distance divided by time taken during the ascend =
![\frac{4}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7B5%7D%20)
÷ 6.375 = 0.125 feet/minute
I guess it's because tangent is written as y/x and slope is x/y
