(a)
To determine : The inequality relating to the average cost per calendar to the desired cost per calendar.
The required inequality is
Given information :
A school is publishing a wildlife calendar to raise money for a local charity. The total cost of using the photos in the calendar is
Explanation :
Let the number of calendars to be printed be
The total cost of printing
The average cost of printing
The school wants the average cost per calendar to be below
(b)
To graph : The inequality to find the number of calendars needed to be printed to bring the average cost per calendar below $10.
Given information :
A school is publishing a wildlife calendar to raise money for a local charity. The total cost of using the photos in the calendar is
Graph :
The inequality is
Interpretation :
The number of calendars needed to be printed to bring the average cost per calendar below $10 is more than
(c)
To calculate : The number of calendars to be printed to have the average cost per calendar below
The number of calendars to be printed to have the average cost per calendar below
Given information :
A school is publishing a wildlife calendar to raise money for a local charity. The total cost of using the photos in the calendar is
Explanation :
Let the number of calendars to be printed be
The total cost of printing
The average cost of printing
The school wants the average cost per calendar to be below
Solve the inequality.
Therefore, the number of calendars to be printed to have the average cost per calendar below

- Thank you.arrow_forwardThank you.arrow_forwardLet V, W, and Y be vector spaces. Suppose dim(V) dim(W) = dim(Y) = 2. = Let ("beta") be an ordered basis for V. Let ("gamma") be an ordered basis for W. Let ("zeta") be an ordered basis for Y. Suppose S is a linear transformation from V to W and that T is a linear trans- formation from W to Y. Remember that ToS is the function from V to Y defined by (TOS)(v) = T(S(v)). (a) Prove that To S is a linear transformation. (b) Prove that ° [T • S] = [T]{[S]}.arrow_forward
- Let W={(0, a, 0) | a Є R}. (a) List four elements from W. (b) Determine whether W is a subspace of R³, and prove that your answer is correct.arrow_forwardFor this problem, refer to the network as shown in Figure 1, answer the following questions. B A C FIGURE 1. For Problem (7). Let x₁ be the number of users at website A. Let x2 be the number of users at website B. Let x3 be the number of users at website C. Assume that there are a total of 900 users at these three websites. This gives us the following system of linear equations: x1 = x2 + 1x3 x2 = x1 + x3 x3 = x2 = 900 x1 + x2 + x3 = (a) Put this system into a standard form (with all variables on the left side and with the constants on the right), and convert that system into an augmented matrix, and then... (b) Use elementary row operations to put the augmented matrix into reduced row echelon form, and then... (c) Write down the solution space for this system of equations, and then... (d) Identify which website(s) would be ranked most highly by PageRank.arrow_forward4 2 Let C = -6 -3 (a) Find det(C). (b) Use your answer for (a) to determine whether C is invertible.arrow_forward
