Does y=-2x represent a function

11.5 gallons of gas will be required for 621 miles.

Let us assume the gas required for 621 miles be x. The rate of gas utilization for 243 miles = 243/4.5

The rate of gas utilization for 621 miles = 621/x. The gas consumed will be equal in both the cases, hence, equating the two equations.

243 ÷ 4.5 = 621 ÷ x

x = (621 × 4.5) ÷ 243

Performing multiplication on Right Hand Side of the equation

x = 2794.5 ÷ 243

Performing division on Right Hand Side of the equation

x = 11.5 gallons

Hence, 11.5 gallons of gas is required.

sin(x) is a mathematical function that calculates the sine of angle x, where x is in radians.

In mathematics, angles are measured in radians or degrees. The symbol π represents the mathematical constant pi, which is approximately equal to 3.14159.

When we say π/2, it means half of the circumference of a circle, which corresponds to 90 degrees.

The inequality "π/2 < 0" suggests that π/2 is less than zero, implying that the angle of 90 degrees is negative. However, this is incorrect.

In the standard coordinate system, angles are measured counterclockwise from the positive x-axis.

Thus, π/2 or 90 degrees lies in the positive direction. The correct relationship should be "π/2 > 0" to indicate that the angle is greater than zero.

The present worth of the tuition cost for a student planning to enroll at the university for 9 years, with the first 4 years costing $7,200 per year and a 5% annual increase for the next 5 years, can be calculated at an interest rate of 8% per year. The present worth is $23,455.297.

To calculate the present worth of the tuition cost, we need to consider the time value of money, which accounts for the fact that money in the future is worth less than money in the present. We can use the concept of present value to determine the worth of future cash flows in today's dollars.

For the first 4 years, the tuition cost is constant at $7,200 per year. To find the present value of these cash flows, we can use the formula for the present value of a fixed cash flow series. Applying this formula, we find that the present value of the first 4 years' tuition cost is

\(7,200 + 7,200/(1+0.08) + 7,200/(1+0.08)^2 + 7,200/(1+0.08)^3.\)

For the next 5 years, the tuition cost increases by 5% per year. We can use the concept of future value to calculate the value of these cash flows in the last year of the 9-year period. Applying the formula for future value, we find that the tuition cost in the last year is \($7,200*(1+0.05)^5.\)

Finally, we can sum up the present value of the first 4 years' tuition cost and the future value of the tuition cost in the last year to obtain the total present worth of the tuition cost for the 9-year period.

Answer: how nice of you :) may god bless you too however You didn’t send the questions

By solving equations we know that there are 30 giraffes and 40 ostriches in the zoo.

A mathematical statement known as an equation is made up of two expressions joined by the equal sign.

A formula would be 3x - 5 = 16, for instance.

When this equation is solved, we discover that the number of the variable x is 7.

So, calculate as follows:

Let g represent giraffes and o represent ostriches.

g + o = 70 ...(1)

4*g + 2*o = 200  ...(2)

g = 70 - o, according to equation 1, therefore we may enter that number in place of g in equation 2 to obtain:

4*g + 2*o = 200

4*(70-o) + 2*o = 200

280 - 4o + 2o = 200

-2o = 200 - 280

2o = 80

o = 80/2

o = 40

Ostriches are 40 then giraffes will be:

70 - 40 = 30

Therefore, by solving equations we know that there are 30 giraffes and 40 ostriches in the zoo.

The number of peanuts and raisins for 7 portions is 35 and 63 respectively.

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

Given that, the ratio of peanuts to raisins in one portion is 5:9.

Number of peanuts and raisins you will need if you make 7 portions and 12 portions.

Now, 5×7 : 9×7

35:63

Here, 5×12 : 9×12

So your slope will be 1/2 and it’s positive sine both x and y is positive.

The value of x for the given circle G for the given measures of angles is 98.

Given a circle with center G.

The circle has been divided in to various sectors by drawing lines from G to  E, F and D.

The measures of central angles formed at these secrtors is also given.

We have to find the value of x.

∠DGF = 89°

∠EFG = x + 32°

∠EGD = x + 43°

Since all these angles form the total angle of the circle at the center, the sum of these angles is 360°.

89 + x + 32 + x + 43 = 360

2x + 164 = 360

2x = 196

x = 98

Hence the value of x is 98.

Additional reference geometry such as user-created reference planes can be created to reference other planes besides the default top, left and right planes. The given statement is false

Additional reference geometry is a useful tool in CAD software that allows users to create reference planes, axes, and points to assist in the creation of complex models. While the default top, left and right planes are often used as a starting point for reference geometry, users are not limited to these planes. In fact, users can create reference geometry that references any existing plane, axis, or point within the model. This allows for greater flexibility and precision when creating complex models.

In conclusion, it is false that additional reference geometry must reference the default top, left, and right planes. Users can create reference geometry that references any existing plane, axis, or point within the model for greater flexibility and precision.

Answer:

Step-by-step explanation:

In expressions, there are 4 items to look at :

1. Terms

2. Coefficients

3. Like Terms

4. Constant Terms

Since 4. is the topic at hand, let's focus on that, constant terms are terms that cannot be changed value.

This would mean numbers without a variable, look at the expression below :

7x + 3

Since 3 doesn't have a variable, therefore 3 is a constant term.

The correct answer is A. Standard deviation measures the dispersion or variability around the expected value or mean of a data set. It is a commonly used statistical measure to quantify the spread of data points.

Standard deviation is calculated by taking the square root of the variance. The variance is the average of the squared differences between each data point and the mean. By squaring the differences, negative values are eliminated, ensuring that the measure of dispersion is always positive.

A higher standard deviation indicates greater variability or dispersion of data points from the mean, while a lower standard deviation suggests that the data points are closer to the mean.

On the other hand, the mean (option B) is a measure of central tendency that represents the average value of a data set. It does not directly measure the dispersion or variability around the mean.

The coefficient of variation (option C) is a relative measure of dispersion that is calculated by dividing the standard deviation by the mean. It is useful for comparing the relative variability between different data sets with different scales or units.

The chi-square test (option D) is a statistical test used to determine if there is a significant association between categorical variables. It is not a measure of dispersion around the expected value.
