The domain of the function \(f(x) = \sqrt{\frac{1}{3}x + 2\) is (d) x  ≥ -6

From the question, we have the following parameters that can be used in our computation:

\(f(x) = \sqrt{\frac{1}{3}x + 2\)

Set the radicand greater than or equal to 0

So, we have

1/3x + 2 ≥ 0

Next, we have

1/3x  ≥ -2

So, we have

x  ≥ -6

Hence, the domain of the function is (d) x  ≥ -6

Answer:

y= -(2/5)x

Step-by-step explanation:

When you graph this line you can see it clearly passes through the point (5,-2)

Answer:

y + 2 = -2/5 (x - 5)

OR

y = (-2/5)x

Step-by-step explanation:

There are many ways you can find the equation.

There are two main ones, one called point-slope form, and the other called slope intercept form.

Point-slope form is easy. All you need a a point on the line, and the slope! Since they give you that in the question, all you need to do is plug things in.

Point slope form is y - \(y_{1}\) = m(x - \(x_{1}\))

x and y are any points. \(x_{1}\) and \(y_{1}\) are the points that the problem gives you. m is the slope.

The equation would be y + 2 = -2/5 (x - 5).

Slope intercept form is a bit harder. You need a point and the y-intercept.

Since you already have the slope, all you need to find is the y-intercept.

Slope intercept form is y = mx + b

x and y are the given points. m is the slope, and b is the y-intercept.

The y intercept is when the x value of a point is 0.

To find b, you can plug in the information you have, which is the point and the slope.

y = mx + b

-2 = (-2/5)(5) +b

-2 = -2 +b

b = 0

Since b is 0, the equation would just be y = (-2/5)x.

The given points H, I, J, and K form a parallelogram.

The slopes of the sides can be calculated using the formula:

Slope = (change in y) / (change in x)

Slope of side HI:

= (1 - (-2)) / (7 - 4) = 3 / 3 = 1

Slope of side IJ:

= (4 - 1) / (4 - 7) = 3 / (-3) = -1

Slope of side JK:

= (1 - 4) / (1 - 4) = (-3) / (-3) = 1

Slope of side KH:

= (-2 - 1) / (4 - 1) = (-3) / 3 = -1

Now, let's calculate the lengths of the sides:

Length of side HI:

= √(7-4)² + (1+2)²

= √9 + 9

= √18

Length of side IJ:

= √(4-4)² + (4-1)²

= √0+ 9

= √9

=3

Length of side JK:

= √(4-1)² + (4-1)²

= √9 + 9

= √18

Length of side KH:

= √(4-1)² + (-2-1)²

= √9 + 9

= √18

Based on the slopes and lengths, we can identify the type of quadrilateral: The given points H, I, J, and K form a parallelogram.

Answer: k = √27-i

Step-by-step explanation:

The concentration of the dilute sugar solution is 0.266 M (mol/L).

To find the concentration of the dilute solution, we need to calculate the number of moles of sugar present before and after dilution and then divide it by the final volume of the solution.

Given that the initial volume of the sugar solution is 150.0 ml and the final volume after dilution is 762.5 ml, we have a dilution factor of 762.5 ml / 150.0 ml = 5.0833.

The concentration of the initial sugar solution is 5.35 m (mol/L), which means that there are 5.35 moles of sugar in 1 liter of the solution. We can calculate the number of moles of sugar in the initial solution as (5.35 mol/L) * (0.150 L) = 0.8025 moles.

After dilution, the number of moles of sugar remains the same. So, the number of moles of sugar in the final solution is also 0.8025 moles.

To calculate the concentration of the dilute solution, we divide the number of moles of sugar (0.8025 moles) by the final volume of the solution (0.7625 L) to get 0.8025 moles / 0.7625 L = 1.0516 M (mol/L).

Therefore, the concentration of the dilute sugar solution is approximately 0.266 M (mol/L).

a) Each side of the square is 9 cm long. b) The perimeter of the shape is 18 cm.

Perimeter refers to the total length of the boundary or outer edge of a two-dimensional shape.

a) The perimeter of a square is the sum of the lengths of all its sides. Since all sides of a square are equal, we can divide the perimeter by the number of sides to find the length of one side:

Perimeter of square = 4 x Length of one side

36 cm = 4 x Length of one side

Divide both sides by 4:

Length of one side = 36 cm / 4 = 9 cm

Therefore, each side of the square is 9 cm long.

b) To find the perimeter of the shape made by cutting an equilateral triangle from a rectangle, we need to add up the lengths of all its sides.

The length of the rectangle is equal to the length of the base of the equilateral triangle plus the length of one of its sides. Since the equilateral triangle has all sides equal, we can find its length by dividing the length of the rectangle by 2:

Length of equilateral triangle = Length of rectangle / 2

Length of equilateral triangle = 7.2 cm / 2 = 3.6 cm

The perimeter of the equilateral triangle is three times its side length:

Perimeter of equilateral triangle = 3 x Length of one side

Perimeter of equilateral triangle = 3 x 3.6 cm = 10.8 cm

The perimeter of the shape is the sum of the length of all its sides, which is the sum of the length of the rectangle and the perimeter of the equilateral triangle:

Perimeter of shape = Length of rectangle + Perimeter of equilateral triangle

Perimeter of shape = 7.2 cm + 10.8 cm = 18 cm

Therefore, the perimeter of the shape is 18 cm.

It would grow by approximately 1.6668 inches to 1.2504 inches

In Lixue's garden, the green pepper plants grew 5 inches in 3-4 months. To find out how many feet they can grow in one month, we can use the given information.

Let's start by converting the inches to feet. Since there are 12 inches in a foot, we divide 5 inches by 12 to get the equivalent in feet: 5 inches ÷ 12 = 0.4167 feet (rounded to four decimal places).

Now, we need to determine how much they can grow in one month. Since the plants grew 0.4167 feet in 3-4 months, we divide this amount by the number of months to find their average monthly growth.

If we assume that the plants grew 0.4167 feet in 3 months, their monthly growth rate would be 0.4167 feet ÷ 3 months = 0.1389 feet per month (rounded to four decimal places).

If we assume that the plants grew 0.4167 feet in 4 months, their monthly growth rate would be 0.4167 feet ÷ 4 months = 0.1042 feet per month (rounded to four decimal places).

Therefore, based on the given information, the green pepper plants can grow approximately 0.1389 feet to 0.1042 feet in one month, depending on whether we consider a 3-month or 4-month timeframe.

Number of items would be the x quanitity because it illustrates the quantities supplied which is the independent variable. The cost is always on the y axis because it shows the minimum price that a supplier would accept for a given quantity meaning it's the dependent variable.

No heteroscedasticity exists. companies are unable to receive funds from formal lenders. the model has a poor goodness-of-fit.

a.The assumptions that the researcher has imposed to estimate equation (1) to get unbiased estimators are as follows: The error term (ε) is normally distributed and has a mean of zero and a constant variance for all observations. The independent variables (X1, X2, X3, and X4) are exogenous. The independent variables (X1, X2, X3, and X4) have no multicollinearity problem. No heteroscedasticity exists.

b.The independent variables from equation 2 which are affecting the demand for informal finance significantly at 1% are X1 and X4.

c. The cultural fractionalization (X1) in Malaysia causes social ties to weaken because there is a lack of trust among people. As a result, companies are unable to receive funds from formal lenders. This is where informal finance comes in handy.

since individuals from the same cultural background can provide funds to each other and earn a profit. Furthermore, if a company's revenues increase, its demand for informal finance (X4) will increase as well. As a result, it is obvious that X1 and X4 are two significant variables that affect the demand for informal finance in Malaysian firms.

d. Adjusted R2 and its explanationThe adjusted R2 is calculated by the following formula:Adjusted R2 = 1 - [(1 - R2) * (n - 1) / (n - k - 1)]Where n is the sample size and k is the number of independent variables.The adjusted R2 is 0.0311 for this study. It means that the independent variables (X1, X2, X3, and X4) in equation (2) can only explain 3.11% of the variation in the dependent variable (Y). Therefore, the model has a poor goodness-of-fit.

To determine the width of the frame surrounding a picture measuring 8 inches by 12 inches, we need to solve a mathematical equation. Given that the area of the frame and picture together is 320 square inches, we can find the width of the frame by subtracting the area of the picture from the total area.

Let's assume the width of the frame to be x inches. The dimensions of the entire framed picture, including the frame, will be (8 + 2x) inches by (12 + 2x) inches. The area of the entire framed picture can be calculated by multiplying these dimensions. Therefore, the area of the frame alone is equal to the area of the entire framed picture minus the area of the original picture (8 inches by 12 inches). We have the equation (8 + 2x)(12 + 2x) - (8)(12) = 320. By solving this equation, we can find the value of x, which represents the width of the frame.

There were 18 good eggs out of the 30 eggs collected by Hanna. The question states that Hanna collected 30 eggs and brought them to Kelsey. Kelsey inspected the eggs and found that 40% of them were broken.

To find the number of eggs that were still good, we need to subtract the number of broken eggs from the total number of eggs.

First, let's find the number of broken eggs. To do this, we multiply the total number of eggs (30) by the percentage of broken eggs (40% or 0.40).

30 eggs * 0.40 = 12 broken eggs

So, out of the 30 eggs collected by Hanna, 12 of them were broken.

To find the number of good eggs, we subtract the number of broken eggs from the total number of eggs collected.

30 eggs - 12 broken eggs = 18 good eggs

Therefore, there were 18 good eggs out of the 30 eggs collected by Hanna.
