a.
To write: an equation which describes the given conditions.
a.
Answer to Problem 5P
Explanation of Solution
Given information: a store charges $15 for each movie and charges $1 for each song.
Let the numbers of songs that we can buy be
Then the charges for song is $
And let the number movies that we can buy be
Then the charges for movie is $15
Since we have only $60, then the total charges should be equal to $60.
The required equation is
b.
To find: domain and range of the equation found in part (a).
b.
Answer to Problem 5P
Domain: {60, 45, 30, 15, 0}.
Range: {0, 1, 2, 3, 4}
Explanation of Solution
Given information: an equation is given as follows-
Since the number of movies and songs can be only whole numbers then suitable domain range according to the given equation are-
Domain: {60, 45, 30, 15, 0}.
Range: {0, 1, 2, 3, 4}.

- 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
