The relationship c(x) = 4.5+ 0.32x it is a linear relationship.

The factor 0.32 is used to reduce the cost of the weight before adding to the fixed cost of  4.5

Given data

c(x) = 4.5+ 0.32x

The relationship c(x) = 4.5+ 0.32x it is a linear relationship.  It can be compared to the equation of a straight line which is

y = mx + c

m is the slope and c is the y intercept

The comparison shows that

y = c(x)

c = 4.5

m = 0.32

If the cost is related with the relationship c(x) = 4.5+ 0.32x.

it can be seen that even when there is no weight or no salad that is at    x = 0 the cost is c = 4.5.

This means that there is a fixed cost of 4.5 for any salad weight, in ounces bought.

The factor 0.32 is used to reduce the cost of the weight before adding to the fixed cost of  4.5.

The 0.32 is a reduction factor because the value is less than 1 and will reduce any number it multiplies.

Given: a quadratic function with vertex (2,3) opening upward .

Find: the given statement is true or false.

Explanation: if parabola has a vertex at (2,3) and opens upward, it has one real solution., (2,3) will be a lowest point. The vertex will be at lowest point, it will be minimum.

that means graph has no one real solution. hence it will never going to intersect. so this statement is false.

Final answer: the given statement is FALSE.

To maximize the volume, of the rectangular prism, the carton should have dimensions of approximately 10.74 inches (length), 10.74 inches (width), and 5.37 inches (height).

Assuming the height of the rectangular prism is h inches.

According to the given information, the length and width of the prism will be twice the height, which means the length is 2h inches and the width is also 2h inches.

The total surface area of the rectangular prism is given by the formula:

Surface Area = 2lw + 2lh + 2wh

Substituting the values, we have:

576 = 2(2h)(2h) + 2(2h)(h) + 2(2h)(h)

576 = 8h² + 4h² + 4h²

576 = 16h² + 4h²

576 = 20²

h² = 576/20

h² = 28.8

h = √28.8

h = 5.37

The height of the prism is approximately 5.37 inches.

The length and width will be twice the height, so the length is approximately 2 * 5.37 = 10.74 inches, and the width is also approximately 2 * 5.37 = 10.74 inches.

The answer for the above expression is 16/9.

An expression is a combination of numbers, variables, and mathematical operations, such as addition, subtraction, multiplication, division, exponentiation, and root extraction, that represents a mathematical quantity or a mathematical statement. An expression can be as simple as a single number or variable, or it can be a complex combination of several numbers, variables, and operations.

According to the given information:

The expression "\((\frac{3}{4} )^{2}\)" represents the fraction "3/4" raised to the power of "-2". In mathematical notation, this is written as "\((\frac{3}{4} )^{-2}\)".

To calculate this value, we can use the rule that a negative exponent is equivalent to taking the reciprocal of the base raised to the positive exponent. Therefore, "\((\frac{3}{4} )^{-2}\)" is equal to the reciprocal of "3/4" raised to the power of "2", or "\(\frac{1}{(\frac{3}{4} )^{2}}\)".

Evaluating this expression, we get:

\((\frac{3}{4} )^{-2}\)= \(\frac{1}{(\frac{3}{4} )^{2}}\) = \(\frac{1}{(\frac{9}{6})^{2} }\)= 16/9

So, "\((\frac{3}{4} )^{-2}\)" is equal to 16/9.

The simplified ratio of total marbles to red marbles is 27 to 8

In this question, we have the following parameters

Blue marbles = 24

Red marbles = 16

White marbles = 14

The above parameters mean that

Total marbles = sum of the individual marbles

Substitute the known values in the above equation, so, we have the following representation

Total marbles = 24 + 16 + 14

Evaluate

Total marbles = 54

The ratio is then represented as

Ratio = Total : Red

This gives

Ratio = 54 : 16

Simplify ratio

Ratio = 27 : 8

Hence, the simplified ratio is 27 : 8

The perimeter of the equilateral triangle is 45 meters.

An equilateral triangle is a polygon that has three sides that are of equal length. The sum of angles in an equilateral triangle is 180 degrees. The perimeter of an equilateral triangle  is the distance round the triangle. It can be determined by adding the length of the three sides of the triangle together.

The first step is to determine the side length of the triangle. The base can be determined from the area.

Area of a triangle = 1/2 x base x height

97.5 = 1/2 x 13 x b

b = (97.5 x 2) / 13

b = 15 meters

Perimeter = 15 x 3 = 45 meters

Based on the information, the value of W would be approximately 8.79.

To find the value of W we must take into account the area of the painting. Once we have this value in mind we must know that the area of a rectangular figure or grid is found by multiplying the base by the height.

According to the above, what we must do is replace the value of w in the operation (2w + 12) and later find the area with the multiplication:

w*(2w+12)

So, if we replace the value of w by 8.79 we will have a value very close to the given area of the figure.
