Hi I'm a student in an algebra 2 class and i need help with 2 questions. I asked my friends but none of them knew the answer to them. Thanks in advanced!
1)For 1980 throughout 1990, the number ofunits produced by a manufacturing plant canbe modeled by
N = 9t + 5
where N is measured in thousands of unitsand t = 0 corresponds to 1980. The profit perunit can be modeled by
P = 9t − 5
where P is measured in dollars and t = 0corresponds to 1980.
Find an expression for the total profit T.
What was the total profit in 1985?
2)A tunnel goes through a mountain whoseshape can be modeled by
h = −64x2 + 19x
where h is the height (in miles) and x is thedistance (in miles) from the opening of thetunnel.
Find the length of the tunnel.
