The temperature on Mars may reach a high of 70 degrees Fahrenheit at the equator in the summer. It may reach a low of -225 degrees Fahrenheit at the poles. Which expression gives the difference between those temperatures?

Answer:

x = 65 y =65 z = 65

Step-by-step explanation:

∠x = ∠y because they are subtended by the same arc

only options that have x and y = each other is 1 and 3

it's definitely not 1 because 50, 50 and 50 make 150 and triangles = 180

so it's 3

50 + 65 + 65 = 180

The number of fruit pies  is 15 and the number of bottles of fruit juice is 7

We are given;

Cost of each fruit pie = $6

Cost of each bottle of fruit juice = $2

Total amount earned = $104

Let x  represent  the number of fruit pies  that Mr. Sanchez's class sold

Let 22 - x  be   the  bottles of   fruit juice that Mr. Kelly's class sold

Thus, we  have the equation;

6x + 2(22  - x)  =  104

Expanding the bracket gives;

6x + 44 - 2x = 104

4x = 104 - 44

4x = 60

x = 60/4

x = 15

Thus, the number of fruit pies  = 15

Number of bottles of fruit juice = 22 - 15 = 7

The equation is an identity. Mathias is correct.

Equations are mathematical statement that shows that two expressions are equal. Equality sign is compulsory for an equation.

as example, 2x + 5Y =12 is an equation that has two variables.

An identity is an equation that is considered as true in all the cases whether any value is substituted or not.

given, 2x² + 10x +6 = (x+3) (2x+1) + 3(x+1)

From the right-hand side, (x+3) (2x+1) +3 (x+1)

                                  we expand, {x × 2x + x×1 + 3×2x + 3×1 + 3 ×x + 3×1}

                                                        2x² + x +6x+ 3 +3x +3

                    we collect the same term, 2x²+ x+ 6x+3x + 3+3

                         we add the same term, 2x² +10x +6

                                                          = left hand side

If you propose to go to the films as soon as every week, you ought to be part of the club to store cash:

True. According to the graph, the pink line (club) is consistently beneath the black line (non-membership) after the preliminary club price. Joining the membership might bring about paying less in keeping with film and save you cash in the end, in particular, if you often visit the movies.

If you watch five films according to year, you'll save money if you do NOT be a part of the film membership:

False. From the graph, it could be discovered that for any variety of films watched, the red line (membership) is always underneath the black line (non-club). Therefore, becoming a member of the club would nonetheless prevent cash even in case you watch only five films in keeping with 12 months.

An individual who joins the film club will start saving money as quickly as they see their first movie:

False. Joining the membership requires paying the membership fee, which is $45. Therefore, a person would want to look at sufficient films to compensate for the club rate before they begin saving cash.

A non-member can pay $60 to observe 20 films:

False. The graph no longer provides unique values for personal movie costs. Without these statistics, we cannot decide the precise fee for non-participants to look at 20 movies.

If a member and a non-member both watch 30 films in a yr, they'll pay the identical amount:

False. The graph indicates that the red line (membership) is always below the black line (non-membership) for any quantity of movies watched. Therefore, if both a member and a non-member watch 30 films, the member would pay much less than the non-member.

If a member watches 50 movies, it'll come to be costing a mean of precisely $3 in step with film:

True. The graph indicates that a person whether a member or a non-member if who watches 30 movies in a year, will pay the same amount. It is because the red line (membership) intersects with the black line (non-membership) at point 30, thus indicating the same cost for both categories.

The evidence that would help Marisa conclude that no chemical reaction occurred in a science experiment is option d) no new substance was formed.

A reaction is termed a chemical reaction if there is a change in the reactants involved. These changed substances have properties different from that of the original. This is what segregates chemical reactions from physical ones like boiling, freezing, breaking, etc.

According to the law of conservation of mass, the number of atoms will remain the same even if the chemical reaction has occurred. It is the number of molecules that changes. A chemical reaction cannot create any new element. It creates new compounds or decomposes existing ones into different elements.

Hence, the conclusion of no reaction occurred can be supported only by the evidence of no reaction of new substances.

The largest interval over which the general solution is defined is (-∞, +∞). There are no transient terms in the general solution, so the answer is NONE.

To find the general solution of given differential equation, we'll solve it using an integrating factor. The given differential equation is:

y' + 7x^6y = x^6

Identify the form of the equation as y' + P(x)y = Q(x), where P(x) = 7x^6 and Q(x) = x^6.

The integrating factor is given by IF = e^(∫P(x)dx). In this case, P(x) = 7x^6, so the integrating factor is:

IF = e^(∫7x^6dx) = e^(7/7 * x^7) = e^(x^7)

Multiply the original equation by integrating factor:

e^(x^7)(y' + 7x^6y) = e^(x^7)(x^6)

Simplify and integrate both sides:

e^(x^7)y + 7∫(x^6e^(x^7))dx = ∫(x^6e^(x^7))dx

The integral on the right side can be evaluated to find a particular solution. For the left side, we have:

e^(x^7)y = ∫(x^6e^(x^7))dx

Let u = x^7, du = 7x^6dx

∫(x^6e^(x^7))dx = (1/7)∫e^udu = (1/7)e^u + C1 = (1/7)e^(x^7) + C1

Substituting this back into the equation:

e^(x^7)y = (1/7)e^(x^7) + C1

Solve for y:

y = (1/7) + C1e^(-x^7)

Therefore, the general solution to the differential equation is:

y(x) = (1/7) + C1e^(-x^7)

The largest interval over which the general solution is defined is (-∞, +∞) since there are no singular points or restrictions specified.

So, the answer is NONE.

Using the provided conditions for the roots and the value for the degree of the polynomial, The required equation is : \(x^{6} + \sqrt2 x^{5}+9x^{4}+9\sqrt2 x^{3}\) .

An equation's roots are just another way of indicating that the equation has "solutions." Solutions are the numbers that, once the variable has been solved, are equal to it. Set f(x)=0 and solve the equation for x to determine where the function meets the x-axis. The x-intercept is the root of the equation, which is discovered by solving the equation for x, if the function is a linear function of degree 1, where f(x)=mx + b.

The highest degree of a polynomial's monomials with non-zero coefficients is referred to as the polynomial's degree in mathematics. A term's degree is a non-negative integer and is calculated by adding the exponents of all the variables that occur in it.

imaginary roots are conjugate in nature,

The statement that best summarizes the bounded rationality model of problem solving and decision making is 'Managers are comfortable making decisions without identifying all options'. Therefore, the correct option is B.

This is because the bounded rationality model recognizes that managers have limitations in their cognitive ability to process all information and alternatives, and therefore they use heuristics and simplified decision-making processes. However, this does not mean that they completely ignore options or do not consider the consequences of their decisions. Instead, they focus on the most relevant information and use their experience and judgment to make the best possible decision given the constraints they face.

Therefore, while option A) is partially correct, it does not capture the essence of the bounded rationality model. Option C) is too idealistic and implies that managers have unlimited time and resources to generate all possible options, which is not realistic. Option D) is not accurate as the bounded rationality model does not rely solely on statistical rules for decision making. Hence, the correct answer is option B.

Note: The question is incomplete. The complete question probably is: Which statement best summarizes the bounded rationality model of problem solving and decision making? A) Managers critically view the world as complex and multivariate. B) Managers are comfortable making decisions without identifying all options.

The price which the widgets should be sold for, for the company to make the maximum profit is $39.

The maximum value of a function is a point on the graph where the function reaches its highest point.

In order to determine the maximum profit which this company can expect to earn, we would differentiate the given profit function with respect to x:

y = -x² + 78x - 512

y' = -2x + 78

0 = -2x + 78

2x = 78

x = 78/2

x = 39.

f(39) = -(39)² + 78(39) - 512

Step-by-step explanation:

The point estimate of the population standard deviation for the given data set (13, 15, 14, 16, 12) is 1.581. Therefore, the correct option is A.

The data is collected from a simple random sample from an infinite population. In order to calculate the point estimate of the population standard deviation for the given data:

1. Calculate the mean (average) of the data set:

(13+15+14+16+12) / 5 = 70 / 5 = 14.

2. Subtract the mean from each data point and square the result:

(13-14)^2=1, (15-14)^2=1, (14-14)^2=0, (16-14)^2=4, (12-14)^2=4.

3. Find the sum of these squared differences:

1+1+0+4+4 = 10.

4. Divide the sum by the number of data points minus 1 (this is the degrees of freedom):

10 / (5-1) = 10 / 4 = 2.5.

5. Take the square root of the result to find the point estimate of the population standard deviation:

√2.5 = 1.581.

Hence the point estimate of the population standard deviation is 1.581. Hence, option A is the correct answer.

On solving the provided question, we can say that - Area enclosed by the square and the circle= 400 - 314 = 86 ft sq

Every point in the plane that is a certain distance away from a certain point forms a circle (center). It is, thus, a curve formed by points moving in the plane at a fixed distance from a point. A circle is a closed two-dimensional object where every pair of points in the plane are equally spaced out from the "center." A line that goes through the circle creates a specular symmetry line. At every angle, it is also rotationally symmetric about the center.

Side of the square =20feet

Therefore,

Radius of the inscribed circle= 20/2 = 10 feet

Area of square=20 X 20 = 400 feet sq.

Area of circle=\(\pi * r^{2} \\\pi * 10*10\\3.14*100\\314 ft sq\)
