Question

Lucas’s friend Isabel is performing in a singing competition. The winner of the competition will be determined by

call-in votes. To help Isabel earn votes, Lucas sends text messages to 8 of his friends. He then asks each of his friends to send texts to 8 more friends, and asks his friends to ask each of their friends to send 8 texts. He is hoping for this pattern to continue and that many people will receive text messages telling them to vote for Isabel. Each set of text messages is a round of text messages, where Lucas’s messages are the first round, Lucas’s friends messages are the second round, and so on.

What would a diagram look like modeling the first few rounds of the situation?

If you know the number of texts sent in round x-1, how many texts will be sent in round x?

How many texts will be sent in round x? In other words, what is the explicit definition (algebraic expression) of the number of texts sent in any round, x?

Question

Roshan is a fourth grader who is being evaluated for poor scholastic performance in mathematics. He has always

been a happy, healthy child, has socialized with friends at school, and presents no behavioral concerns at home. However, his math performance has always been below the average for his grade, and now he is performing so far below his peers that he is really beginning to be upset about it. While being evaluated for a learning disorder, the PMHNP appreciates that Roshan has had a marked deficit in his ability to recognize and understand symbols and order clusters of numbers. This suggests a deficit in:

A. Linguistic skills

) Define the relation M(A B) A ∩ B 6= ∅ where the domains for A and B are all subsets of Z For each of

Define the relation M(A, B) : AnB # 0, where the domains for A and B are all subsets of
Z. For each of the five properties of a relation defined in this chapter (reflexive, irreflexive,
symmetric, antisymmetric, and transitive) either show M satisfies the property, or explain
why it does not.
Hint: This problem causes a lot of grief. The relation M is a relation between subsets of
Z. For example, {1, 2}M{9} is false, since {1, 2} n {9} = 0. But {1, 2} M {2, 4,6, 7} is true
since {1, 2} n {2, 4, 6, 7} = {2}, and not 0.
(bonus) Let A = 0 and consider the empty relation, E = 0, on A. For each of the five prop-
erties of a relation defined in this chapter (reflexive, irreflexive, symmetric, antisymmetric,
and transitive) either show M satisfies the property, or explain why it does not.
Warning: Reasoning about the empty set can cause grave mental anguish. Suggestion:
write out each of the five definitions you need to check (reflexive, symmetric, etc.) and
decide if the statement is true or false.
For example: For the reflexive condition, the statement to check is
Vr(c E0 = (1,I) ( E)
Since the left side of the implication (x 6 0) is definitely false (after all there isn’t any-
thing in the empty set!) the entire implication is true (recall the truth table for implication).
That means the proposition above is true, and so E is reflexive. Reasoning for the remain-
ing four conditions all follow a similar pattern.

Question

There is a single price (profit maximizing) monopoly in a given industry, selling a perfectly divisible good. The

market demand is P = β-Q, where β>0 is the maximum willingness to pay, P represents the price and Q represents the quantity. The total cost function is C(Q) = γQ, where 0≤γ≤β. What is the monopoly’s profit? What is the monopoly-optimal price (i.e., the price that maximizes the monopoly profit)?

All numerical answers must be fractions. Do not use decimals.

Question

I need step by step instructions for finding answers to these questions and similar. I am confused on what formula

to use and then some of the formulas have extra steps.

  1. A 3-ft wide circular track for a camera dolly is set up for a movie scene. The two rails of the track form concentric circles. The radius of the inner circle is 62 ft. How much further does the wheel on the outer rail travel than the wheel on the inner track?

The correct answer is 18.8ft, but I got a different answer using the formula Area of a circle = (pie)(radius)^2. WHat should I be doing?

I am more interested in the formula’s used to solve these than the answers. Thank you SO much!

Calculus: Lagrange multiplier and production/utility function

costs him around 40 dollars. Suppose that the utility derived by him from 3 many lunches
and d many dinners in a month is given by the utility function U(E, d) = 101050104. (a) (8 pts) Assuming that Brian has 800 dollars a month in total to spend on eating out,
how many lunches and dinners should he buy to maximize his utility? Use the method of Lagrange multipliers. (b) (1 pts) What is the interpretation of A in this context? (You do not need to compute
A.) (c) (8 pts) Imagine that Brian doesn’t care about money but he wants to eat out exactly
20 times a month (including lunches and dinners). How should he distribute his eating
out among lunches and dinners to maximize his utility? Use the method of Lagrange
multipliers. (d) (1 pt) What is the interpretation of A in this context? (You do not need to compute A.)

Question For the function f(x) = 5(2x + 1) (x 2)2 (x 6)I

Question

Question:

For the function: f(x) = -5(2x + 1) (x – 2)2 (x – 6)

I

was able to answer the following about this function:

Dominant term is -10×4

The graph starts low and ends low. The roots are -1/2, 2 (bounces off), and 6.

I was able to sketch the graph without a calculator, roughly, and could see that the domain is {x e R}. From the answers section of the textbook, I saw that the range is {y e R, y or equal to 500}. So the highest y value for the graph is 500.

My concern is, how is it possible to determine the maximum value of y (500) without a calculator? I believe there is a method in calculus but my course is a grade12 Advanced Functions course for Ontario, Canada and calculus is not taught.

Please help. If a calculus method is all that is available (short of using a calculator) please explain.

Suppose that prior to land restrictions of 1984 the market for land disposal was modeled as follows demand

Question

suppose that prior to land restrictions of 1984 the market for land disposal was modeled as follows:

demand

(MPB)=80-2L

supply(MPC)=20-2L

where L is in 1000 tons of landfill hazardous waste and the dollar values are per ton.

when the 1984 restrictions decreases the supply of land disposal services the marginal private cost changes to mpc=32+2L

quantify the decrease of land disposal services accomplished at his restriction and make a appropriate conclusions.

math is required, show your work

hint: find equilibrium (price and quantity) before and after 1984 restrictions (supply=demand)

Hi so I have a calculus question involving curve sketching and such heres the question A twice

Question

A twice

differentiable function, f(x), has a domain of [-6, 6] (4)

a) Identify the value(s) of x over [-6, 6] for which f has a local minimum.

b) Identify the interval(s) over [-6, 6] for which the function f is concave up.

c) Identify the value(s) of x over [-6, 6] for which f has a point of inflection.

d) Given f (-6) = 5, sketch a possible graph of f.

Im having some confusion. what exactly does it mean if f”(x) is 0 over an interval. i know if the second derivative is 0 it may be an infelction point. Idk i think im just confusing myself with the way things are written and im having trouble with the sketch. i got a parabola that passes through -2 but not sure if its correct
