Answers
Given : The function h(d)=2d+4.3 relates the height (h) of the water in a fountain in feet to the diameter (d) of the pipe carrying the water in inches.
To Find : h(1.5) and interpret your solution in the context of the problem.
value of d when h(d)=10.3 and interpret your solution in the context of the problem
Solution.
Function
h(d)=2d+4.3
d = 1.5
h(1.5) = 2(1.5)+4.3
= 3 + 4.3
= 7.3
When pipe diameter is 1.5 inch then height of water is 7.3 feet
h(d) =10.3
2d + 4.3 = 10.3
2d = 6
d = 3
For 10.3 feet fou tain height , diameter of pipe required.is 3 inch
