So, in this problem you already have the equations set up for how much money each one works. You have Jim, earning a starting amount of $35, plus an additional $3 for every hour he works. You also have John, who gets $8.


The variable in the equations is h, which stands for hours. From there, you can put the three different h values (6, 7, and 8) into the equations to see who gets more money.


For instance, for Day 1, Jim gets 35+3x6 dollars, or 35+18=$53, while John gets 8x6 dollars, or $48. You can substitute in 7 and 8 and do the same process to get the answers for Day 1 and 2.


Hope this helps!

aliina [53]

The graph shows the height h, in feet, of s football at time t, in seconds, from the moment it was kicked at ground level.

We are supposed to find the average rate of change in height from t=1.5 seconds to t=1.75 seconds.

Average rate of change in height=\frac{\text{Change in Height}}{\text{Time taken}}\\

As we can see from the the change in distance for the time interval 1.5 second to 1.75 second=12-7=5

and time=1.75-1.5=0.25

Average rate of change in height=\frac{5}{0.25}\\=20ft/sec

Hence Required Rate of change is -20 ft/sec, because its falling(In the direction of negative y-aixs)
