For given expression x will be equal to 1.

What are expressions?

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between. The mathematical operators can be of addition, subtraction, multiplication, or division. For example, x + y is an expression, where x and y are terms having an addition operator in between. In math, there are two types of expressions, numerical expressions - that contain only numbers; and algebraic expressions- that contain both numbers and variables.

e.g. A number is 6 more than half the other number, and the other number is x. This statement is written as x/2 + 6 in a mathematical expression. Mathematical expressions are used to solve complicated puzzles.

Now,

Given expression is m/2=18x-1

Step-by-step explanation:

with each lawn mowed he earns more money so if he makes 3 lawns he makes a profit of 30x3=90 dollars

Answer:

Step-by-step explanation:

The graph that shows the relationship between the number of lawns Chris mows in a week and the amount of money he makes is a linear graph. On the x-axis, the number of lawns mowed would be represented, and on the y-axis, the corresponding amount of money Chris makes would be represented. As Chris makes $30 for each lawn he mows, the graph would be a straight line that goes through the origin (0,0), and for each increase of 1 lawn mowed, there would be a corresponding increase of $30 in the amount of money made.

Graphs can be shifted vertically in both straight and curved lines.

Graphs can be vertically moved in both linear and curvilinear directions. Add or remove a number from the constant to change the equation's graph vertically. G(x) = f(x) + c and G(x) = f(x) - c are the formulas for an upward and a downward shift, respectively.

Given a function f, a new function g(x) = f(x - h) is created, where h is a constant. This new function is a horizontal shift of the original function f. Graph shifts to the right if h is positive. If h is low, the graph will move to the left.

Given a function f(x), a new function g(x) = f(x) + k is created, which is a vertical shift of the original function f(x). The output values all shift outward by k units. The graph will move upward if k is positive. The graph will tilt downward if k is negative.

The statistical decision you could make from this information is that the two variables are dependent and unlikely to occur by chance.

In a chi-square test of independence, a p-value of 0.0000 means that the probability of observing the data or a more extreme result given that the null hypothesis is true is very small. In this case, the p-value is less than the level of significance (0.05), which means that you would reject the null hypothesis.

Based on this information, you could make the statistical decision that there is evidence to suggest that there is a relationship between the two variables being tested and that this relationship is unlikely to have occurred by chance. This means that you would conclude that the variables are dependent on each other and not independent.

The statement that is true about Scientific process and method is the scientific process is a continuous process of collecting data and refining hypothesis.  

Studies and researches are done by a scientific method which follows certain standards and protocols. The method starts with an observation, a question is asked why it happens and formulating a hypothesis. Either we can do a controlled experiment to test whether the hypothesis is correct or not, or we can do a non-experimental hypothesis, where experimenting will not be ethical.

The scientific process is a continuous process, which need to be collecting data and refining hypothesis. Even our data support hypothesis, the data might not be true in some cases. So work on a scientific concept is never complete. Even if we have data on causes and effects of a natural phenomena, we could not necessarily predict it every time, example: earthquake. Also, while collecting data, we should be fair in its treatment. We can't take data that only support our hypothesis.

So, the correct statement is option c. Scientific process is a continuous process of collecting data and refining hypotheses.

The angle through which one of these tires will rotate during the warranty period is approximately 3.168 × 10⁸ radians.

To find the angle in radians, we need to know the distance that the tire covers and convert it to radians.

The distance covered by the tire can be found by multiplying the circumference of the tire by the number of rotations it makes. The circumference of the tire can be calculated as follows:

C = 2πr

where r is the radius of the tire

Since the diameter is given, the radius can be found by dividing the diameter by 2:

r = diameter/2

So,

C = 2π × (diameter/2) = π × diameter

The number of rotations can be found by dividing the distance covered by the tire by the circumference:

distance covered = 60,000 miles

1 mile = 5280 feet

distance covered = 60,000 × 5280 feet

rotations = distance covered/circumference

Using the above equations, we can find the angle (in radians) through which the tire rotates during the warranty period as follows:

angle = rotations × 2π

angle = (60,000 × 5280/(π×2.0)) × 2π = 3.168 × 10⁸ radians

So, the angle through which one of these tires will rotate during the warranty period is approximately 3.168 × 10⁸ radians.

To make an equation with fractions simpler we will be required to take up and LCM and cross-multiplication.

When an equation has fractions, there can be a case where each side, the LHS and the RHS, have multiple fractions with different denominators or even whole numbers.

In this case, first, you have to make sure to take an LCM for fractions on each side and make sure each side has only one denominator and all the constants and variables are a part of that fraction.

Then you have to take the denominator from each side and then multiply it with the numerator of the other. For example-

If an equation looks like [2x - 3]/5 = [4x + 8]/7

Here LHS has 5 as the denominator while RHS has 7

Hence, we will take 5 over to the RHS and 7 to LHS to get

7 X [2x - 3] = 5 X [4x + 8]

Now we have gotten our simpler form.

As for the function f(x) = x + 8 has no values of x where its derivative is equal to 7

A "function" is a mathematical concept that assigns a unique output to each input. The derivative of a function gives us information about how the function is changing at any given point.

In this question, we are asked to find the values of x where the derivative of the function f(x) = x + 8 is equal to 7.

Here we have to solve this problem, we can start by finding the derivative of the function f(x) = x + 8.

The derivative of this function is f'(x) = 1, which means that for every unit increase in x, the function f(x) increases by 1 unit.

Next, we set f'(x) = 7 and solve for x.

This gives us the equation 1 = 7, which is not possible.

3. Determine the value of f (x, y) for every pair of x and y.

4. Plot the grid points based on the values of f. (x, y).

5. To create the contour map, connect the points with equal values along a curved line.

In a two-dimensional plane, a contour map is a graphical representation of a function that displays all the points with identical values. It is used to illustrate how the function changes in relation to the two variables. Draw a grid on the two-dimensional coordinate plane and give values to the x- and y-coordinates before drawing a contour map for a function f (x, y). Once this is done, determine the value of f (x, y) for each pair of x and y, and plot the points on the grid using those values (x, y). To complete the contour map, draw a curved line connecting the points of equal value. The contour map will display the function's regional extrema as well as any locations where it is rising or decreasing locally. Additionally, it can be used to pinpoint regions of the plane where the function's value is constant.

The coordinates of the oriented length whose tail has coordinates (1, 2, 3) and whose head has coordinates (3, -2, 7) can be calculated using vector subtraction, which is (2,-4,4) or (-2,4,-4)

Vector subtraction is a method of subtracting one vector from another, resulting in a new vector. The new vector will have the same direction as the vector being subtracted, and a magnitude equal to the difference of the magnitudes of the vectors being subtracted.

In this case, the vector being subtracted is from the tail to the head, so the new vector will point from the head to the tail.

The vector from tail to head can be written as:

Tail to Head = (3, -2, 7) – (1, 2, 3) = (2, -4, 4)

Therefore, the vector from head to tail is:

Head to Tail = – (2, -4, 4) = (-2, 4, -4)
