MA141 Week 1 Acme Inc Revenue per Share in 2014 Precalculus Questions Can someone help me with these 19 questions and explain some of the answers also. I am not very good with Pre-Calculus. 1) The revenue per share for Acme, Inc. was $1.17 in 2013 and $3.25 in 2015. Estimate the revenue per
share in 2014.
Use the Midpoint Formula and assume that the function relating revenue to shares is linear.
2) The resistance y (in ohms) of 1000 feet of copper wire at 68 degrees Fahrenheit is given by
the function y = 10,370/ x2 , where x is the diameter of the wire in thousandths of an inch.
(a) Fill in the table:
x
10
20
30
40
50
60
70
80
90
100
y
b) Use the table above to estimate the resistance when x = 45.5 and for x = 75.5.
c) Compare your answers in part b with the values calculated by using the function.
d) What can you conclude about the relationship between the diameter of the copper wire
and the resistance?
3) A school purchases a printer for $24,000. It has a 10 year life expectancy. Its value at that time is
expected to be $2000. Write a linear equation giving the value V of the equipment during the 10 years it
will be in use.
4) A manufacturer of games notes that the variable cost for producing a game is $0.90 per unit and the
fixed costs are $6000. Each game sells for $1.65. If x is the number of games produced. Determine the
following:
a) Express the total cost C as a function of x = number of games produced.
b) Write the average cost per unit C = C as a function of x
5) Use the graph of the function to answer parts (a)–(d).
a) Find the domain and range of f.
b) Find the zero(s) of f.
c) Determine the open intervals on which f is increasing, decreasing, or constant.
d) Approximate any relative minimum or relative maximum values of f.
A line passes through the two points P(3, 3),and Q(–5, –5). Write the equation in slope-intercept form.
