Answer:
Marginal Average Cost Function C'(x) = 5.7
Step-by-step explanation:
The Marginal Average Cost is just the first differential of the Cost Function
[tex]\dfrac{d}{dx} C(x) = \dfrac{d}{dx}(161) + \dfrac{d}{dx}(5.7x)\\\\\\The first differential of a constant is 0 and the first differential of ax is a \\\\So ,\\\\\dfrac{d}{dx} C(x) = 0 + 5.7 = 5.7[/tex]
This means that as x increases by 1 unit, cost increases by 5.7 units. x presumably refers to the number of units produced
The Marginal Revenue can be found the same way
[tex]\dfrac{d}{dx} R(x) = \dfrac{d}{dx}6x - \dfrac{d}{dx}(0.08x^2)\\\\\dfrac{d}{dx}6x = 6\\\\\dfrac{d}{dx}(0.08x^2) = (2)(0.08)x[/tex]
[tex]= 0.16x[/tex] since [tex]\dfrac{d}{dx} (x^2) = 2x[/tex]

17. John is making flower arrangements. He has 45 roses, 27 irises, and 18daisies. What is the GREATEST number of bouquets he can make using atleast one of each flower and each bouquet having the SAME arrangement?(He has to use ALL the flowers) *Options 452193
Answers
To find the greates number of bouques he can make, we need to find the greatest number that divdes the three numbers: 45, 27 and 18.
45 can be divided by the following numbers:
1,3,4,5,9,15,45
27 can be divided by the following numbers:
1,3,9,27
18 can be divided by the following numbers:
1,2,3,6,9,18
From the divisors of the three numbers we can see that the greatest number that divide the three of them is 9.
Thus, 9 is the greatest number of bouquets he can make using at leat 1 of each. Also those 9 bouquets would have all the same arrengement.
Answer: 9

Fourteen percent of the town's population is over the age of 65. If there are 322 residents over the age of 65, approximately what is the town's population?
Answers
If 14 percent of the town's population is over the age of 65 and there are 322 residents over the age of 65, then the population of the town is 2300
The percentage of people over the age of 65 = 14%
Number of residents over the age of 65 = 322
Consider the total population of the town as x
Then the equation will be
x × (14/100) = 322
From this equation we have to find the value of x, that is the population of the town.
x × (14/100) = 322
x × 0.14 = 322
x = 322/0.14
x = 2300
Hence, if 14 percent of the town's population is over the age of 65 and there are 322 residents over the age of 65, then the population of the town is 2300

There is a game where the outcome is a random integer from 1 to 50. If the outcome is odd, you wi $26. If the outcome is even, you win nothing. If you play the game, what is the expected payoff?
Answers
We have a game like the one described in the question and we have to calculate the expected payoff, which is equal to the sum of the possible outcomes weighted by the probability of that outcome.
In this case we have two outcomes:
1) We get an odd number and we win $26 (W=26).
2) We get an even number and we get $0 (W=0).
To calculate the probabilities of each oucome we have to know the proportion of odd an even numbers in the list of 1 to 50. We have a total of 50 numbers, rom which 25 are odd numbers and 25 are even numbers, so the probability of each outcome can be calculated as the relative frequency of each category:
[tex]\begin{gathered} P_1=\text{ number of odds / total numbers}=\frac{25}{50}=0.5 \\ P_2=\text{ number of evens / total numbers}=\frac{25}{50}=0.5 \end{gathered}[/tex]Then, we can calculate the expected payoff as:
[tex]E=\sum ^n_{i=1}p_iW_i=p_1W_1+p_2W_2=0.5\cdot26+0.5\cdot0=13+0=13[/tex]p_i: probability of outcome i.
W_i: prize when outcome i happens.
Then, the expected payoff for this game is $13.
Answer: the expected payoff for this game is $13.

By using free body diagrams and trigonometric relations, the normal force of the block of iron has a magnitude of 352.579 newtons.
What is the normal force of the block of iron?
In accordance with the third Newton's law, normal forces (N), in newtons, are reactive forces as the result of the contact of the iron mass with the ground of the incline, that is to say, the normal force is the reaction of the weight of the iron mass (W), in newtons. If the iron mass is at rest, then we find the following free body diagram of the ground-mass system and its related geometric system.
Since the free body diagram represents a three force system, then the magnitude of the normal force is found by trigonometric relations:
N = W · cos 26°
N = (40 kg) · (9.807 m / s²) · cos 26°
N = 352.579 N
The normal force of the block of iron has a magnitude of 352.579 newtons.

The slope of the line that would be parallel to h(x) is the same as the slope of h(x)
The slope of the line that would be perpendicular to h(x) would be negative inverse of the slope of line h(x)

The solution of a system of linear equations is the point where the two lines meet. Note that for the given equations, both lines have the same slope (4/5). If two lines have the same slope, it means that those lines are parallel. Parallel lines do not meet at any point, they stay parallel to the infinite.
Therefore, since this two lines are parallel, they don't meet and the system has no solution.

How to Determine the Graph of a Linear Equation?A linear equation can be expressed as y = mx + b, which is the slope-intercept form where the slope is represented as m and the y-intercept is represented by b. This y-intercept is the point where the line intercepts the y-axis when x is equal to zero.
Given the linear equation, 24x + 64y = 384, rewrite in slope-intercept form to easily figure out the slope:

64y = -24x + 384
y = -24x/64 + 384/64
