The ordered pairs from the graph of quadratic and linear equations are (-2, 7) and (2, -1)

A graph of a quadratic equation is a parabolic curve that opens up or down, depending on the sign of the coefficient of the squared term. A general form of a quadratic equation is given by:

y = ax^2 + bx + c,

where a, b, and c are constants. The graph of this equation can be plotted by choosing a range of values for x and calculating the corresponding values of y.

A graph of a linear equation is a straight line. A general form of a linear equation is given by:

y = mx + b,

where m is the slope of the line and b is the y-intercept.

In this problem, the ordered-pairs will be the point in which they intersect with each other.

Looking carefully at the graph, the ordered pair will be at points

According to the question The function that calculates h for a given value of T For a. \(\[ h_a = \left( \frac{{G \cdot M \cdot T_a^2}}{{4\pi^2}} \right)^{\frac{1}{3}} - R \]\) , For b. \(\[ h_b = \left( \frac{{G \cdot M \cdot T_b^2}}{{4\pi^2}} \right)^{\frac{1}{3}} - R \]\) , For c.  \(\[ h_c = \left( \frac{{G \cdot M \cdot T_c^2}}{{4\pi^2}} \right)^{\frac{1}{3}} - R \]\).

In this function, we use the formula for the orbital period of a satellite:

\(\[ T = 2 \pi \sqrt{\frac{h^3}{G M}} \]\)

where:

- `T` is the orbital period of the satellite in seconds

- `G` is the gravitational constant

- `M` is the mass of the Earth

- `h` is the altitude of the satellite above the Earth's surface

By rearranging the formula, we can solve for `h`:

\(\[ h = \left(\frac{G M T^2}{4 \pi^2}\right)^{1/3} - R \]\)

Let's assume the following values for the constants:

\(\( G = 6.67430 \times 10^{-11} \, \text{m}^3 \, \text{kg}^{-1} \, \text{s}^{-2} \)\) (gravitational constant)

\(\( M = 5.972 \times 10^{24} \\) , \(\text{kg} \)\) (mass of the Earth)

\(\( R = 6.371 \times 10^{6} \, \text{m} \)\)  (radius of the Earth)

Using these values, we can calculate the altitudes for satellites orbiting the Earth.

a) Once a day: \(\( T = 24 \times 60 \times 60 \, \text{s} \)\)

b) Once every 90 minutes: \(\( T = 90 \times 60 \, \text{s} \)\)

c) Once every 45 minutes: \(\( T = 45 \times 60 \, \text{s} \)\)

Now let's substitute these values into the formula to calculate the altitudes:

a) For once a day:

\(\[ h_a = \left( \frac{{G \cdot M \cdot T_a^2}}{{4\pi^2}} \right)^{\frac{1}{3}} - R \]\)

b) For once every 90 minutes:

\(\[ h_b = \left( \frac{{G \cdot M \cdot T_b^2}}{{4\pi^2}} \right)^{\frac{1}{3}} - R \]\)

c) For once every 45 minutes:

\(\[ h_c = \left( \frac{{G \cdot M \cdot T_c^2}}{{4\pi^2}} \right)^{\frac{1}{3}} - R \]\)

By substituting the values and evaluating the expressions, we can find the altitudes for each case.

Answer:

See below.

Step-by-step explanation:

1)

So we have the equation:

\(2x+3y=1470\)

To change into the slope-intercept form, we need to isolate the y-variable. Thus, subtract 2x from both sides:

\((2x+3y)-2x=(1470)-2x\)

The left side cancels:

\(3y=1470-2x\)

Now, divide both sides by 3. The left side cancels:

\((3y)/3=(-2x+1470)/3\\y=-\frac{2}{3} x+490\)

The slope-intercept form is:

\(y=mx+b\)

Where m is the slope and b is the y-intercept.

Thus, the slope is -2/3 and the y-intercept is 490.

2)

So, since we already know the y-intercept is 490, plot a point at (0,490).

The slope is too small to use. Thus, multiply the fraction by 100. It is now (-200/300). This means that we move down 200 for every 300 (recall that the slope means rise over run. Thus, we move down 200 for every 300 to the right). Thus, another possible point would be (0+300,490-200) or (300,290). Plot that. Then, connect them.

3)

To write in in function notation, simply substitute the y-variable for the function notation. Our independent variable here is x so we'll use that.

\(y=-\frac{2}{3}x+490\\ f(x)=-\frac{2}{3}x+490\)

This means that for every x sandwiches made, there is f(x) wraps made for the total sum to be $1,470.

For example, if 105 sandwiches were made, then f(105)=-2/3(105)+490=420 wraps were made for the total profit to be $1,470.

4)

Please refer to the attached graph.

5)

First, since the total profit has now increased, the graph above and to the right of the old graph. This is because Sal needs to sell more sandwiches and wraps. Likewise, because of this, the x- and y-intercepts will also be different. Nevertheless, if converted into the slope-intercept equation, the slope will remain the same.

What is a rhombus?

A rhombus is a four-sided quadrilateral with all sides of equal length. It is also known as a diamond or a lozenge. In a rhombus, opposite sides are parallel, and opposite angles are equal. Additionally, the diagonals of a rhombus bisect each other at right angles, meaning they intersect at a 90-degree angle and divide each other into two equal segments.

Since a rhombus has all sides of equal length, we know that YZ = AB. Therefore, if YZ = 12, we have:

AB = YZ = 12

The critical t-value is approximately 1.753.

To find the critical value for a 96% confidence interval with a sample size of 15, we need to determine the t-value from the t-distribution table. The t-distribution table is a statistical tool used to determine the probability of a t-value given the degrees of freedom (df) and the desired level of significance (α).

In this case, we have a sample size of 15, which means our degrees of freedom are 14 (n - 1). Looking at a t-distribution table for 14 degrees of freedom and a 96% confidence interval.

This means that if we were to construct a confidence interval from a sample size of 15, the margin of error would be calculated by multiplying the critical t-value of 1.753 by the standard deviation of the sample and dividing by the square root of the sample size. The resulting interval would contain the population mean with 96% confidence.

It's essential to note that the critical value will change as the sample size and confidence level change. Therefore, it's crucial to use the correct table to find the corresponding critical values for a given dataset's sample size and confidence level.

To determine under what conditions Chris would choose not to buy any Red Bulls, further information or constraints are needed. The marginal utility per dollar spent can be calculated for each item, providing insights into their relative importance in maximizing utility.

To determine under what conditions Chris would choose not to buy any Red Bulls, we need additional information such as the price of Red Bulls and Chris's preferences and budget constraints specifically related to Red Bulls. Without such information, it is not possible to ascertain the conditions under which Chris would choose not to buy any Red Bulls.

Moving on to the utility function and expenditure question, given the utility function U = 6ln(b) + 2ln(c) + ln(s) + x, where b represents loaves of bread, c represents kilos of cheese, s represents kilos of salami, and x represents dollars left over to spend on other goods and services, the consumer aims to maximize utility.

To determine the optimal bundle, the consumer will allocate their budget of $160 to purchase specific quantities of bread, cheese, and salami while leaving a portion for other goods and services. The specific amounts purchased will depend on the prices of bread, cheese, and salami and their respective marginal utilities.

Calculating the marginal utility per dollar spent on bread, cheese, salami, and other goods and services will reveal the relative importance of each item in maximizing utility. By comparing these values, we can identify which goods provide the highest marginal utility per dollar spent and are, therefore, the most beneficial in terms of utility maximization.

There are several possible reasons why the experimental result of the relationship between the variable "n" and "r" is not exactly an inverse-square relationship.

Measurement errors can contribute to deviations from the expected inverse-square relationship. Even small errors in measuring the values of "n" and "r" can accumulate and affect the overall results. Additionally, the experimental setup might have limitations or constraints that introduce systematic errors. For example, if the distances involved are very small or very large, there may be deviations due to the breakdown of assumptions made in the inverse-square relationship.

Moreover, the presence of additional factors can also influence the relationship between "n" and "r." In real-world scenarios, various factors such as external forces, environmental conditions, or inherent complexities in the system can affect the relationship. These factors might introduce non-linearities or perturbations that lead to deviations from the expected inverse-square relationship. Understanding and accounting for these additional factors is crucial for accurately interpreting the experimental results and improving the model or theory that describes the relationship between "n" and "r."

The camper should take 3 units of food, 1 first-aid kit, and 1 piece of clothing within the given constraints.

To determine the optimal number of each item the camper should take, we need to maximize the total benefit while considering the capacity constraint of the backpack.

Let's assume the camper takes x units of food, y first-aid kits, and z pieces of clothing.

The backpack has a capacity of 9 ft^3, and each unit of food takes up 2 ft^3. Therefore, the constraint for food is 2x ≤ 9, which simplifies to x ≤ 4.5. Since x must be a whole number and the camper needs at least one unit of food, the camper can take a maximum of 3 units of food.

Similarly, for first-aid kits, since each kit occupies 1 ft^3 and the camper must take at least one, the constraint is y ≥ 1.

For clothing, each piece takes 3 ft^3, and the constraint is z ≤ (9 - 2x - y)/3.

Now, we need to maximize the total benefit. The benefit of food is assigned as 7, first aid as 5, and clothing as 6. The objective function is 7x + 5y + 6z.

Considering all the constraints, the possible combinations are:

- (x, y, z) = (3, 1, 0) with a total benefit of 7(3) + 5(1) + 6(0) = 26.

- (x, y, z) = (3, 1, 1) with a total benefit of 7(3) + 5(1) + 6(1) = 32.

- (x, y, z) = (4, 1, 0) with a total benefit of 7(4) + 5(1) + 6(0) = 39.

- (x, y, z) = (4, 1, 1) with a total benefit of 7(4) + 5(1) + 6(1) = 45.

Among these combinations, the highest total benefit is achieved when the camper takes 3 units of food, 1 first-aid kit, and 1 piece of clothing.

Therefore, the camper should take 3 units of food, 1 first-aid kit, and 1 piece of clothing to maximize the total benefit within the given constraints.

The perimeter of a circle with a diameter of one-fifth of a meter is approximately 15.7 centimeters.

The diameter of the circle is one-fifth of a meter, which means it is equal to 0.2 meters. The formula to calculate the perimeter (circumference) of a circle is given by the equation P = πd, where P is the perimeter, π is the mathematical constant pi (approximately 3.14), and d is the diameter of the circle. Substituting the given values, we have P = 3.14 * 0.2 = 0.628 meters. To convert this value to centimeters, we multiply by 100 since there are 100 centimeters in a meter.
