Step-by-step explanation:

The area of a rectangle is length ✕ width. So, width = area/length, i.e., 24 square units/4 units or 6 units.

Because its sides are coupled, it only has two distinct dimensions. The rectangle’s length is traditionally the longer of these two dimensions, although when the rectangle is displayed standing on the floor, the vertical side is commonly termed the length.

A rectangle’s opposite sides are equal and parallel. Because a rectangle is a 2-D form, it has two dimensions: length and breadth. The length of the rectangle is the longer side, while the width is the shorter side. Square units of measurement include square inches, square feet, and square meters. To calculate the area of a rectangle, multiply its length by its breadth. The formula is as follows: A = L * W, where A

Consequently, the airplane's speed in still air 250 mph and Therefore, the wind's speed is 50 mph.

Its simplest form is thought to be the number's smallest equivalent fraction. How to determine the simplest form. Look for shared factors in the denominator and numerator. A fractional number can be checked to discover if it is a prime number. A statement having two spherical geometry and an equal sign in the middle is referred to as a mathematical equation. Every variable's degrees are listed in descending order in the general form of any equation. The formula for a linear equation is x + b = 0.

given

Now solve any problem for one variable. In the first equation, I'll find the value of x:

200mph = p - w

On both sides, add w:

p = 200mph Plus w

Now that we have the x from the first equation, we can use it to solve for w in the second equation:

200 mph + w + w Equals 300 mph

Add related phrases together for 300 mph: 200 mph plus two

200 mph on both sides are subtracted:

100mph = 2w

50 mph divided by two is w.

Therefore, the wind's speed is 50 mph.

To find the plane's speed, enter the value we just discovered back into either equation. I'll enter it into the first equation.

200 mph = (p - 50 mph)

50 mph extra on both sides

250mph = p

The centroid of the region is (3,1).

The centroid of a region is a point that is the average of all the vertices of the region. In other words, it is the point that is the center of mass of the region. To find the centroid of a region, we need to find the x and y coordinates of the vertices of the region and then take the average of these coordinates.

To find the centroid of the region in the first quadrant bounded by the x-axis, the parabola y^2 = 8x, and the line x + y = 6, we need to find the x and y coordinates of the vertices of the region.

The parabola y^2 = 8x and the line x + y = 6 are the equations of the boundaries of the region. We can find the vertices of the region by solving for the points where these two equations intersect.

The parabola y^2 = 8x can be rewritten as y = ±√8x. So the x-coordinate of the vertex of the parabola is (3,3).

The line x + y = 6 can be rewritten as y = -x + 6. So the x-coordinate of the vertex of the line is (0,6) and (6,0).

So the three vertices of the region are (0,0), (3,3), and (6,0).

So the centroid of the region is (3,1).

What is the function notation?

Function notation is a way of writing mathematical functions using a specific syntax. A function is a rule that assigns a unique output to each input. In function notation, the function is represented by a letter, usually f, g, or h, followed by a variable in parentheses.

To find (f g)(x), we first need to find g(x) by substituting the value of x into the equation for g(x) = x^2 - 7:

g(x) = x^2 - 7

Next, we substitute the result of g(x) into the equation for f(x) = 2x + 1:

(f g)(x) = f(g(x)) = f(x^2 - 7) = 2(x^2 - 7) + 1

So the final result is (f g)(x) = 2x^2 - 14 + 1 = 2x^2 - 13

Hence, (f g) (x) = 2x^2 - 13

As a result, if [f(x) is (x)], then the equation [y is f(-x + 2)] defines the graphed function.

[y = f(-x + 2)] is the equation that describes the graphed function.

As stated in the question, a reference graph diagram and details on the function f(x), which equals the square root of "x," are given.

From the four possibilities provided, we are expected to select the equation that best explains the graphed function.

We will employ the trial-and-error approach to this problem, employing the possibilities to identify the best solution.

First off, the graph's x-axis and y-axis are both broken at (4, 0) and respectively (0, 2). As a result, [y = f(x)] requires that our equation be equal to 0 when (x = 4) is replaced and to 2 when (x = 0).

Taking into account option (A), we obtain, by substituting (x = 4) for (y = f[(- x) + 4] = sqrt[(- x) + 4]

y = sqrt[(- 4) + 4]

furthermore, y = sqrt (4 - 4)

furthermore, y = sqrt (0)

or, y = 0

The result of replacing (x = 0) is y= [(-0)+4]

or y = sqrt(4) or y = 2 or y = (4-0)

As a result, option (A) is satisfied at locations (4, 0) and (0, 2).

Similar results may be obtained for the other three possibilities by substituting and checking: for (x = 4), (y 0), and for (x = 0), (y 2).

As a result, if [f(x) = (x)], then the equation [y = f(-x + 2)] defines the graphed function.

To find the approximate difference in the percentage of people that liked pepperoni on their pizza and the percentage of people that only liked cheese pizza, we need to find the percentage of people that liked pepperoni and the percentage of people that only liked cheese, and then subtract the smaller percentage from the larger percentage.

From the graph, we can see that 30 people liked pepperoni, 20 people liked mushrooms, 15 people liked sausage, and 10 people liked cheese and olives.

The total number of people Jimmy asked is 30+20+15+10 = 75
