The equivalent of the given Fahrenheit temperature in degree Celsius is 30 °C.

From the question, we are to determine the given Fahrenheit temperature in degree Celsius

From the given information,

The given Fahrenheit temperature is 86 °F.

From the given formula

C = 5/9 (F - 32)

To use this formula to determine the equivalent of a Fahrenheit temperature in degree Celsius, we will substitute the Fahrenheit temperature into the formula and simplify.

C = 5/9 (F- 32)

Substitute F = 86

C = 5/9 (86 - 32)

C = 5/9 (54)

C = 5/9 × 54

C = 5 × 6

C = 30 °C

Hence,

The temperature is 30 °C.

Find gradient:

coordinates taken: (5, 0), (0, 3)

\(\rightarrow \sf \dfrac{y_2-y_1}{x_2-x_1}\)

\(\rightarrow \sf \dfrac{3-0}{0-5}\)

\(\rightarrow \sf -\dfrac{3}{5}\)

equation:

\(\sf \bold{ y = m(x) + b}\)

\(\rightarrow \sf y = -\dfrac{3}{5} x + 3\)

\(\rightarrow \sf y = -\dfrac{3}{5} x + \dfrac{15}{5}\)

\(\rightarrow \sf 5y =-3x+15\)

The fraction \($\frac{9}{12}$\) can be expressed as the sum of the smaller fraction \($\frac{3}{4}$\).

Ryan grew \($\frac{1}{2}$\) feet in a year.

1. To express the fraction \($\frac{9}{12}$\) as a sum of smaller fractions, we can simplify it by dividing both the numerator and denominator by their greatest common divisor. In this case, the greatest common divisor of \(9\) and \(12\) is \(3\).

So, we can rewrite \($\frac{9}{12}$\) as:

\($\frac{9}{12} = \frac{3 \times 3}{3 \times 4} = \frac{3}{4}$\)

Therefore, the fraction \($\frac{9}{12}$\) can be expressed as the sum of the smaller fraction \($\frac{3}{4}$\).

2. To find how much Ryan grew in a year, we need to calculate the difference between his height this year and his height last year.

Let's convert the mixed fractions to improper fractions for easier computation:

Last year's height: \($4 \frac{3}{4} = \frac{4 \times 4 + 3}{4} = \frac{19}{4}feet\)

This year's height: \($5 \frac{1}{4} = \frac{5 \times 4 + 1}{4} = \frac{21}{4} feet\)

To determine the growth, we subtract last year's height from this year's height:

\($\frac{21}{4} - \frac{19}{4} = \frac{21 - 19}{4} = \frac{2}{4} = \frac{1}{2}feet\)

Therefore, Ryan grew \($\frac{1}{2}$\) feet in a year.

The sum of the first n even positive integers is n² + n.

We are given that the sum of the first n even positive integers is (n2 n). that is,

2 + 4 + 6 + 8 .... + 2n = n2 n.

This is known as an Arithmetic Progression (AP) of even numbers with common difference of 2, where a = 2 and d = 2.

To find the sum of an AP, the formula isSn = n/2[2a + (n - 1)d]

Where Sn is the sum of n terms, a is the first term and d is the common difference.

Substituting values in the formula, we get the sum of the first n even positive integers is;

Sn = n/2[2a + (n - 1)d]= n/2[2(2) + (n - 1)(2)]= n/2[4 + 2n - 2]= n/2[2n + 2]= n(n + 1)= n2 + n

Therefore, the sum of the first n even positive integers is n² + n.

The maximum profit if the profits per acre are $75 for corn and $40 for soybeans is $371,255.83. Therefore, the correct option is c.

To find the maximum profit from planting corn and soybeans, we can use linear programming. Let's first define the variables and write the constraints.

Let x be the number of acres of corn and y be the number of acres of soybeans.

1. Total acre constraint: x + y ≤ 6,000

2. Fertilizer/herbicide constraint: 9x + 3y ≤ 40,501

3. Labor constraint: 0.75x + y ≤ 5,250

The objective function to maximize is the profit function: P(x,y) = 75x + 40y

Now, we will use the Solver to find the maximum profit:

Step 1: Set up a spreadsheet with the constraints and the objective function.

Step 2: Go to the Data tab and click on Solver. If Solver is not available, you may need to add it in Excel Options.

Step 3: Set the objective function by selecting the cell with the profit function.

Step 4: Choose "Max" for the objective.

Step 5: Add the constraints by selecting the corresponding cells.

Step 6: Click on "Solve" and the Solver will find the optimal values for x and y.

After using Solver, we find that the optimal values are x = 4,363.89 (corn) and y = 1,636.11 (soybeans), which yields a maximum profit of $371,255.83. Therefore, the correct answer is c: $371,255.83

The counterclockwise circulation around c is 12 and the outward flux through c is zero.

Green's theorem is a useful tool for calculating the circulation and flux of a vector field around a closed curve in two-dimensional space.

In this case,

we have a field f=(7x−4y)i+(9y−4x)j and

a square curve c bounded by x=0, x=4, y=0, y=4.

To find the counterclockwise circulation, we can use the line integral of f along c, which is equal to the double integral of the curl of f over the region enclosed by c.

The curl of f is given by (0,0,3), so the line integral evaluates to 12.

To find the outward flux, we can use the double integral of the divergence of f over the same region, which is equal to zero since the divergence of f is also zero.

The rate of the slow hike is 2.2 mph and the rate of the faster hiker is 4.4 mph.

Here in this issue, we are managing linear equations which is a condition of one variable regularly composed within the form ax+b=0 , where a and b are real numbers and x is an unknown variable. Solutions to linear equations allude to a linear equation that can have zero, one, or infinitely various solutions. A linear equation with no solutions simplifies to an untrue statement such as 1=0. A linear equation with one solution rearranges to a solution of the form x=n where n may be a real number. A Linear equation with infinitely various solutions simplifies to a true statement without a variable such as 1=1.

Here we  considering  the rate of the slow hiker  to be x, so the rate for the fast hiker will be x+2.2

Since we know that  distance = speed * time

therefore, the Distance covered in 5 hours by a slow hiker is 5x , wheras for fast hiker it will be 5(x+2.2)=5x+11 km

As we are given the condition that it i they are  33 miles apart, So

=>5x + 5x+11 = 33

=>10x = 33-11

=>10x = 22

x =22/10 => 2.2

So the rate of a slow hiker is 2.2 mph and the rate of a fast hiker is   x+4.4= 4.4 mph.

The equation that represents the line closest to the curve of best fit would be the equation of the line with the smallest sum of squared residuals.

In order to determine the equation that represents the line closest to the curve of best fit, we first need to find the equation of the curve of best fit. This can be done using regression analysis, such as linear regression or polynomial regression, depending on the shape of the data.
Once we have the equation of the curve of best fit, we can then find the equation of the line that is closest to this curve. This can be done by finding the line that has the smallest sum of squared residuals, which measures the distance between each data point and the line.
Therefore, the equation that represents the line closest to the curve of best fit would be the equation of the line with the smallest sum of squared residuals.

To determine the equation that represents the line closest to the curve of the best fit, you'll need to analyze the given data points and compare the residual errors for each candidate equation. The equation with the smallest sum of squared residuals is generally considered the best fit.
