I wrote your answer on the paper...
The volume flow rate of the air being pumped into the football will be given by:
Q=V*A
Where
V=Speed
A=Area
You know that your pump expels air at speed of 8.2 ft/s
The area of The needle of your pump is
A=pi*r^2=pi*((4.5/1000)*(3.28))^2=0.00068442 ft^2
Finally
Q=V*A=(8.2 ft/s)*(0.00068442ft^2)=0.005612243 ft^3/s
Answer:
y = -1x + 2
Step-by-step explanation:
- y=mx+b
- going down to the right negative slope
- rise over run so 1/1 makes the slope 1
- negative 1 for the slope
- b is the y-intercept and the line lands on the point (0,2)
