if you know a,b,c then you can easily write the linear function
p(h)
Then just
solve for h when p=50 or p=100
since it's a linear function you should find that the 2nd height is twice as high as the first
Water towers are tall to provide enough water pressure to supply all of the houses and
businesses in the area of the tower. Each foot of height provides 0.43 psi (pounds per
square inch) of pressure.
a. Write a sequence for the pressure in psi for each foot of height.
0.43,0.86,1.29,1.72,2.15...=51.6 (up to 15th term)
b. What is the minimum height that supplies 50 psi, a typical minimum supply pressure?
116.3 ft
c. What is the minimum height that supplies 100 psi, which is a typical maximum pressure?
232.5 ft
d. Graph the sequence, and discuss the relationship between the height found for a pressure of 50 psi and the height found at 100 psi.
I know answers to a,b,c but Im having trouble with part d
