We know that the perimeter of a rectangle can be represented by the expression 2l +2w, where l represents the length of the rectangle and w represents the width of the rectangle.

If we substitute in the values given in this problem, we get the expression:
2(2x+6) + 2(x)

Another equivalent expression we can use to express the perimeter is w + w + l + l.

If we substitute in the values given in this problem into this expression, we get:

x + x + 2x + 6 + 2x + 6

Overall, we know that these expressions are equivalent and represent the same value (the perimeter of the rectangle), because if you combine like terms, both expressions simplify to 6x + 12.

Answers

I believe the answer is c. $8. 00

Answer:

Net assest value of one share is $8 .

Option (c) is correct .

Step-by-step explanation:

As given

A mutual fund has total assets of 2.4 million dollars and 300,000 shares.

As 1 million = 1000000

Total assest value = $2.4 × 1000000

Thus

[tex]Net\ asset\ value\ of\ one\ share = \frac{2.4\times 1000000}{300000}[/tex]

Put all the values in the above

[tex]Net\ asset\ value\ of\ one\ share = \frac{24\times 1000000}{300000\times 10}[/tex]

[tex]Net\ asset\ value\ of\ one\ share = \frac{24}{3}[/tex]

Net asset value of one share = $8 .

Therefore net assest value of one share is $8 .

Option (c) is correct .

what are possible solutions to a system of linear equations and what do they represent graphically?

Answers

Hope this  picture helps!

Final answer:

Solutions to a system of linear equations are represented graphically as the intersections of lines on a graph and can be unique, infinitely many, or none. Graphical representations are essential in various applications, like economic models, and software like R facilitates solving these systems.

Explanation:

Possible solutions to a system of linear equations can be one of three types: a unique solution, infinitely many solutions, or no solution. Graphically, these solutions are represented by the intersections of lines on a graph. In the case of a unique solution, the lines intersect at exactly one point.

For example, consider two linear equations of the form y = mx + b. Graphically, each equation is represented by a straight line. Where these lines cross is the solution to the system. If both equations produce the same line, they have infinitely many solutions since every point on the line satisfies both equations.

If 210 people said football was their favorite sport to watch, how many people were surveyed?

Answers

Final answer:

Without additional data, such as the percentage of those surveyed who chose football, it's impossible to determine the total number of people surveyed from the information provided. The data given only specifies that 210 individuals selected football as their favored sport to watch.

Explanation:

Based on the provided question, there's not enough information to determine the total number of people who were surveyed. The information given only states that 210 people picked football as their favorite sport to watch, but it does not provide the overall total number of people surveyed.

To calculate the total number of respondents, you need to know the ratio or percentage of people who chose football. For example, if you knew that football was chosen by 70% of those surveyed, you could use that information to calculate the total number of people. In this case, the equation would be 210 = 0.70 * x. Solving for x (the total number of people surveyed) would give you x = 210 / 0.70, which comes out to approximately 300 people.

mike gioulis would like to have $25,000 in 4 years to pay off a balloon payment on his business mortgage. His money market account is paying 1.825% compounded daily Disregarding leap years, how much money must Mike put in his account now to achieve his goal? round to the nearest whole dollar

Answers

You can do it using daily or continuous compounding

daily interest = .01825/365 
= 5 * 10^-5 
number of periods = 365 * 4 = 1460 

1 + 5*10^-5 = 1.00005 
1.00005^1460 = 1.07573  
1.07573 x = 25,000 
x = 23,240 

if continuous 
a = p e^rt 
a = p e^(5*10^-5*1460) 
a = p e^ (.073) 
a = p (1.07573) 
Final answer:

Mike need to deposit approximately $22,815 in his money market account now, which has a 1.825% interest rate compounded daily, to have $25,000 in 4 years.

Explanation:

To find out how much Mike should invest now, we need to use the formula for compound interest:
A = P(1 + r/n)^(nt)
where:  
 A = the amount of money accumulated after n years, including interest.
P = principal amount (the initial amount of money)
r = annual interest rate (in decimal)
n = number of times interest applied per time period
t = time the money is invested for in years

In this case, Mike wants to have A = $25,000 in t = 4 years. The interest rate r is 1.825% or 1.825/100 = .01825 in decimal form, and since it is compounded daily, n = 365. So, we can plug into the formula and solve for P:
$25,000 = P(1 + .01825/365)^(365*4)

By performing the calculation, we find that P is approximately $22,815. Mike will therefore need to invest this amount in his money market account now to achieve his goal.

Manuel's hourly rate of pay is calculated by dividing his total weekly earnings by the total hours he worked. He worked a total of 30 hours and earned $337.50, resulting in an hourly rate of $11.25.

The question asks us to calculate Manuel's hourly rate of pay based on the total amount he earned in a week and the number of hours he worked. To find the hourly rate, we need to divide the total earnings by the total number of hours worked.

Calculate the total number of hours worked in a week: 5 days a week times 6 hours each day equals 30 hours.

Divide Manuel's total earnings for the week by the total hours worked:
$337.50 divided by 30 hours equals an hourly rate of $11.25.

The limit from the right is the value that x^2 approaches as x approaches 0. That is 0^2 = 0.

Left and right limits are the same, so the limit as x approaches zero is 0.

Given the area of a triangle is 14x^2 +15x+4 and the base is 4x+2,write the algebraic expression for the height

Answers

By definition, the area of the triangle is given by:
 A = (1/2) * (b) * (h)
 Where,
 b: base.
 h: height.
 Clearing the height we have:
 h = (2 * A) / (b)
 Substituting:
 h = (2 * (14x ^ 2 + 15x + 4)) / ((4x + 2))
 h = (14x ^ 2 + 15x + 4) / (2x + 1)
 Making the division of polynomials we have:
 h = 7x + 4
 Answer:
 the algebraic expression for the height is:

What is the 99% confidence interval (z-score = 2.58) for the number of minutes that an adult spends surfing the Internet per day?

Answers

Answer:

The correct answer is 49.1 minutes to 59.3 minutes

Step-by-step explanation:

The 99% confidence interval for the number of minutes that an adult spends surfing the Internet per day is [49.091, 59.308].

What is confidence interval?

A confidence interval (CI) is a range of estimates for an unknown parameter.

The formula for confidence interval is mean ± (standard normal variate at α level of significance)*(standard deviation)/ (√sample size)

CI = 54.2 ± 2.58 * 14/√50

CI = 54.2 ± 5.1081

CI = [49.091, 59.308]

(1 pt) find the coordinates of the point (x, y, z) on the plane z = 3 x + 4 y + 4 which is closest to the origin.

Answers

Final answer:

The solution to the problem involves setting up and solving a system of equations derived from the distance function in 3D. The minimum point of the distance function corresponds to the point in the plane that's closest to the origin.

Explanation:

To find the coordinates of the point (x, y, z) on the plane z = 3x + 4y + 4 which is closest to the origin, we need to find the minimum distance from origin (0,0,0) to any point on the plane. The distance equation is given by √[(x₂−x₁)²+(y₂−y₁)²+(z₂−z₁)²]. This is simply Euclidean distance in 3D.

In this case, we can define the distance function d = √(x² + y²+ (3x + 4y + 4)²). To find the minimum distance, we take the derivative of this distance function with respect to both x and y, set them to 0, and solve the resulting equations. The solutions to these equations yield x and y. We substitute x and y into z = 3x + 4y + 4 to get z.

Finally, solving these equations we obtain the coordinates of the point (x, y, z) on the plane that is closest to the origin.

Answer:

  (-6/13, -8/13, 2/13)

Step-by-step explanation:

You want the point on the plane z = 3x +4y +4 that is closest to the origin.

Normal vector

When the plane equation is written in standard form, the variable coefficients comprise a vector that is normal to the plane. The line normal to the plane and passing through the origin can be written in terms of this vector. Solving for the variable in that equation lets us find the point on the plane where the line intersects.

The standard form equation for the plane is ...

  3x +4y -z = -4 . . . . . . . subtract 4+z from the given equation

Then the normal to the plane is ...

  N = (3, 4, -1)

and the vector equation of the line through the origin is ...

  L = (0, 0, 0) +tN = (3t, 4t, -t)

Point of intersection

The value of t that makes a point on the line satisfy the plane equation is ...

  3(3t) +4(4t) -(-t) = -4

  26t = -4

  t = -4/26 = -2/13

Then the point tN is ...

  (-2/13)(3, 4, -1) = (-6/13, -8/13, 2/13)

The point on the plane closest to the origin is (-6/13, -8/13, 2/13).

Calculate the noon sun angles for new orleans, usa and helsinki, finland on september 22. in the answer below, new orleans answer is listed first. refer to the notes on how to calculate noon sun angles. 36.5 degrees, 6.5 degrees 60 degrees, 30 degrees 83.5 degrees 53.5 degrees

Answers

We need to calculate noon sun angle. Noon sun angle is an angle at which sun-rays fall at noon on a given date.
On September 22, the sun’s rays form a 90° angle at noon at the equator.

Formula for calculating noon sun angle is:

Noon_sun_angle = 90° - Zenith angle

We have complementary angles so we need to substract zenith angle from 90°.

The zenith angle is the distance between subsolar point (point where sun is at 90°) and the latitude of an observer. In our case this angle will have same value as latitude because subsolar point is at equator 0°. If our latitude and subsolar point are at same hemisphere we substract values. Otherwise we add values.

New Orleans, USA
Latitude = 30°
Noon_sun_angle = 90° - 30° = 60°

Helsinki, Finland
Latitude = 60°
Noon_sun_angle = 90° - 60° = 30°

Answer:

60 degrees, 30 degrees

Explanation:

Sun angle = 90° - Zenith angle

On September 22, the sun passes over celestial equator. Equinox occurs.

Zenith Angle = Latitude of the place

Latitude of New Orleans, US = 29.95° ≈ 30°

Latitude of  Helsinki, Finland = 60.95° ≈ 60°

Thus, the Sun angle at noon at New Orleans would be 90° - 30° = 60°

and at Helsinki, Finland would be 90° - 60° = 30°

Zhi bought 18 tickets for games at a fair. Each game requires 3 tickets. Zhi wrote the expression 18 – 3g to find the number of tickets she has left after playing g games. Diego correctly wrote another expression, 3(6 – g), that will also find the number of tickets Zhi has left after playing g games. Use the drop-down menus to explain what each part of Zhi's and Diego's expressions mean.

Answers

Answer: In the picture below.

Step-by-step explanation:

Final answer:

The provided mathematical expressions represent the process of calculating Zhi's remaining tickets after playing 'g' games at a fair. '18 - 3g' symbolizes subtracting three times the number of games played from the initial total (18) tickets. '3(6 – g)', on the other hand, corresponds to multiplying the number of tickets per game (3) by the subtraction of already played games from total possible games (6).

Explanation:

The subject of this question is based on mathematical expressions and variables. In the case of Zhi's expression, 18 represents the total number of tickets she bought. 'g' corresponds to the number of games played, and 3 is the number of tickets required for each game. Therefore, '18 – 3g' means subtracting three times the number of games played (3g) from the total quantity of tickets (18), which would give us the number of tickets left.

Diego's expression, however, expresses the same idea differently. '6 – g' symbolises the number of games Zhi could play before she runs out of tickets (since 18 tickets divided by 3 tickets per game equals 6 games). The '3' outside the bracket is again the number of tickets each game requires. As such, '3(6 – g)' expresses the multiplication of the tickets needed per game (3) by the difference between the total games possible and the games already played (6-g). This, therefore, provides the same result—Zhi's remaining tickets after g games.
