Step-by-step explanation:

The inequality that can be used to represent the number of topsoil and mulch Sam can carry is, 40x + 20y ≤ 480

And, The graph which represents the number of topsoil bags and mulch bags that Sam can move in a single trip is shown in figure.

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that:

Weight of top soil = 40 pounds

Weight of mulch = 20 pounds

Total weight Sam can carry = 480 pounds

Now, Let number of bags of top but soil = x

And, The number of weight of mulch = y

Hence, The inequality is,

⇒ 40x + 20y ≤ 480

Therefore, the inequality that can be used to represent the number of topsoil and mulch Sam can carry is 40x + 20y ≤ 480

And, The graph which represents the number of topsoil bags and mulch bags that Sam can move in a single trip is shown in figure.

The value of ST = 10 for the given rectangle.

A quadrilateral with parallel sides that are equal to one another and four equal vertices is known as a rectangle. It is also known as an equiangular quadrilateral for this reason.

Rectangles can also be referred to as parallelograms because their opposite sides are equal and parallel.

In the given triangle PQRS, the diagonals bisect each other, that is they divide each other in equal halves.

Thus. PT = TR

Since, PT = 10 we have TR = 10,

The diagonals of the rectangle are equal, hence we also have:

TR = ST

e) 6x⁴ = -x² + 5.

A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. It is also known as the polynomial of degree 2 since the greatest degree term in a quadratic function is of second degree. A quadratic function must contain at least one term of the second degree.

Given equations to find the  equations that are quadratic in form,

Standard form refers to the quadratic function f(x) = a(x - h)² + k, where a is not equal to zero. The graph opens either upward or downward depending on the value of a. The vertex is the point, while the line of symmetry is the vertical line x = h.

so equations that are in form of quadratic are,

Answer: 79

Step-by-step explanation: The weighted average for the scores can be calculated as follows:

Lab score: 94 x 0.23 = 21.62

First major test: 89 x 0.215 = 19.135

Second major test: 63 x 0.215 = 13.495

Final exam: 73 x 0.34 = 24.82

Total weighted average: 21.62 + 19.135 + 13.495 + 24.82 = 78.976

Rounding to the nearest whole number, the weighted average is 79.

The final account balance with compound interest is $6,440.30.

The final account balance when compounded semiannually is higher.

The formula for compound interest is:

A = P (1 + r/n)^(nt)

where:

A = the future value of the investment, including interest

P = the principal investment amount

r = the annual interest rate (decimal)

n = the number of times that interest is compounded per year

t = the number of years the money is invested/borrowed for

Part A:

r = 3.92% = 0.0392, P =  $5,460.75, n = 2 (semiannually means twice a year), t = 51 months = 4.25 years

A = P (1 + r/n)^(nt)

A = 5,460.75 (1 + 0.0392/2)^(2*4.25)

A = 5,460.75 (1 .0196)^(8.5)

A = $6,440.30

Thus, the final account balance is $6,440.30

Part B:

The size of an area on a surface can be expressed as an area. The area of an open surface or the boundary of a three-dimensional object is referred to as the surface area, whereas the area of a planar region or planar region refers to the area of a form or planar layer. The total amount of space filled by a planar (2-D) surface or shape of an object is known as its area. Draw a square on a piece of paper using a pencil. a character with two dimensions. The area of a shape on paper is the space it takes up. Imagine that the square is composed of more compact unit squares.

The scale factor defines a variable in a ratio of two different measurements.

Sometimes drawings of large models are represented in a scale factor of a smaller unit.

Given, The scale on a 1 : 50000 ordnance survey map indicates that 2cm on the map = 1km on the ground.

We know 1 km = 1×100000 = 100000 cm.

So, If 2 cm represents 100000 cm it has a scale factor of 100000/2 = 50000.

For b) Estimating the maximum heart rate, a common formula used to calculate maximum heart rate is:

Max HR = 220 - Age

Since the person is 20 years old, the maximum heart rate can be estimated as:

Max HR = 220 - 20 = 200 beats per minute.

To estimate the maximum heart rate given a resting heart rate, we can use the formula:

Max HR = Resting HR + (Max HR - Resting HR) * Percentage of Max HR

Assuming a typical range of 70-85% of maximum heart rate during exercise, the estimated maximum heart rate for a resting heart rate of 40, 60, 72, and 80 beats per minute would be:

Resting HR = 40: Max HR = 140 + (200 - 140) * 0.85 = 170 beats per minute

Resting HR = 60: Max HR = 140 + (200 - 140) * 0.80 = 176 beats per minute

Resting HR = 72: Max HR = 140 + (200 - 140) * 0.75 = 182 beats per minute

Resting HR = 80: Max HR = 140 + (200 - 140) * 0.70 = 188 beats per minute

For c) the correlation coefficient, the coefficient measures the strength and direction of the linear relationship between two variables.

A value close to 1 indicates a strong positive correlation, a value close to -1 indicates a strong negative correlation, and a value close to 0 indicates no correlation.

To model the data with a linear function, find the slope using two points from the table, and use the slope-intercept form of the equation to find the y-intercept. To estimate the maximum heart rate for different resting heart rates, substitute the values into the equation. The correlation coefficient cannot be determined based on the given table of data.

To model the data with a linear function, we can use the formula for the equation of a line, y = mx + b, where m is the slope and b is the y-intercept.

First, we need to find the slope (m). The slope is given by the formula: m = (y2 - y1) / (x2 - x1). We can choose any two points from the table to calculate the slope. Let's choose (60, 200) and (70, 180) as our two points.

Using the formula, we have m = (180 - 200) / (70 - 60) = -20 / 10 = -2.

Now, we can use the slope-intercept form of the equation to find the y-intercept (b). Let's substitute one of the points into the equation: 200 = -2(60) + b. Solving for b, we get b = 320.

Therefore, the equation of the linear function that models the data is y = -2x + 320.

To estimate the maximum heart rate for different resting heart rates, we can substitute the given values into the equation:

If the resting heart rate is 40: y = -2(40) + 320 = 240.

If the resting heart rate is 60: y = -2(60) + 320 = 200.

If the resting heart rate is 72: y = -2(72) + 320 = 176.

If the resting heart rate is 80: y = -2(80) + 320 = 160.

The correlation coefficient measures the strength and direction of the relationship between two variables. In this case, it represents the correlation between resting heart rate and maximum heart rate. The closer the correlation coefficient is to 1 or -1, the stronger the correlation. However, since we are given a table of data and not actual data points, we cannot calculate the correlation coefficient. We can only estimate it visually based on the scatter plot of the data points.

Therefore, the correlation coefficient cannot be determined and our confidence in using the regression line to estimate function values is limited.

then the ratio of perimeters is also [tex]\frac{a}{b}[/tex]

and the ratio of areas is ( [tex]\frac{a}{b}[/tex] )² = [tex]\frac{a^2}{b^2}[/tex]

the ratio of side lengths, yellow to green is

[tex]\frac{36}{60}[/tex] = [tex]\frac{3}{5}[/tex] ( cancelling 36 and 60 by 12 )

the ratio of perimeters is equal to ratio of sides, that is [tex]\frac{3}{5}[/tex]

the ratio of areas = [tex]\frac{3^2}{5^2}[/tex] = [tex]\frac{9}{25}[/tex]

let x be the area of the green figure, then by proportion

[tex]\frac{45}{x}[/tex] = [tex]\frac{9}{25}[/tex] ( cross- multiply )

9x = 1125 ( divide both sides by 9 )

x = 125
