Monthly fee =
Slope intercept form of a line is
Comparing
We get
Therefore
Slope =45
c.
To find: C- intercept.
c.

Answer to Problem 59PPS
C-intercept = 145
Explanation of Solution
Given information:
Start-up fee
Monthly fee =
Slope intercept form of a line is
Comparing
We get
Therefore
C-intercept = 145
d.
To find: Cost for two years membership.
d.

Answer to Problem 59PPS
Explanation of Solution
Given information:
Start-up fee
Monthly fee =
We need to find cost for 2 -year membership.
1 year = 12 months
Therefore
Substitute
We get
Cost for 2-year membership = $1225

- Patterns in Floor Tiling A square floor is to be tiled with square tiles as shown. There are blue tiles on the main diagonals and red tiles everywhere else. In all cases, both blue and red tiles must be used. and the two diagonals must have a common blue tile at the center of the floor. If 81 blue tiles will be used, how many red tiles will be needed?arrow_forwardFind the values of n, if the points (n + 1, 2n), (3n, 2n + 3) and (5n + 1,5n) are collinear.

The water heater is shut off and the water cools to the temperature of the surrounding air, which is 60°F. The water cools slowly because of the insulation inside the heater, and the value of k is measured as 0.00351. a. Write a function that models the temperature T (t) (in °F) of the water t hours after the water heater is shut off. b. What is the temperature of the water 12 hr after the heater is shut off? Round to the nearest degree. c. Dominic does not like to shower with water less than 115°F. If Dominic waits 24 hr. will the water still be warm enough for a shower?
