We need to integrate the function

y = 2x - x² with respect to x, from x = 0 to x = 2.

The graph of the function intersects the x-axis at x = 0 and x = 2.

So,

Area of region R = ∫[0,2] (2x - x²) dx

= [x² - (1/3)x³] from 0 to 2

= [2² - (1/3)(2)³] - [0² - (1/3)(0)³]

= 4/3

Now, let's find the equation of the line y = cx. Since the line passes through the origin (0,0), we have y = cx.

To find the value of c that divides the region R into two equal subregions, we need to find the value of x where the

area under the curve y = 2x - x² is equal to the area under the line y = cx.

∫[0,a] (2x - x²) dx = ∫[0,a] cx dx

[2x²/2 - x³/3] from 0 to a = [c/2 x²] from 0 to a

2a²/2 - a³/3 = c/2 a²

We multiply both sides by 6, we get:

12a² - 2a³ = 3ac

2a² - (1/3)a³ = (1/2)ac

2a - (1/3)a² = (1/2)c

c = (4a - (2/3)a²)/2

We know that the area under the line is equal to the area under the curve up to the point of intersection, we have:

∫[0,a] (2x - x²) dx = ∫[0,a] (cx) dx - ∫[a,2] (2x - x²) dx

2a²/2 - a³/3 = c/2 a² - 2a² + (8/3)a³ - 4a + (4/3)a²

10a³/3 - 7a² + 4a = 0

a = 0, 1.4105, -0.6172

The only value of a that is within the range 0 to 2 is a = 1.4105. Substituting this value into the equation for c, we get:

If two equations are parallel, their slopes are the same.

y=1.5x-6 is written in slope-intercept form, which is:

[tex]y=mx+b[/tex]

Where m is the slope, and b is the y-coordinate of the y-intercept.

Thus, looking at the equation y=1.5x-6, we can find that m=1.5.

This means that the slope is 1.5.

Think of any equation in this format that uses 1.5 as the slope. Here are a few examples:

What is statistics?

Statistics is a branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organization of numerical data. It involves the use of methods and techniques to gather, summarize, and draw conclusions from data.

A. The two quantities you would measure for x and y are the time and height, respectively.

B. The equation that relates time and height for an object in projectile motion is given by:

y = y0 + v0y * t - (1/2) * g * t²

where:

y = vertical height at any time t

y0 = initial vertical height (in this case, the height of the ramp)

v0y = initial vertical velocity (in this case, the vertical velocity of the rider at the top of the ramp)

g = acceleration due to gravity (approx. 9.81 m/s²)

t = time elapsed since the rider left the ramp

To apply this equation to the given image, you can put the picture on a grid with the x-axis representing time and the y-axis representing height.

C. To find the maximum height, you need to determine the point at which the rider's height is greatest. From the plotted points, you can see that the maximum height occurs at the point where the curve reaches its apex. You can find this point by calculating the time at which the vertical velocity of the rider becomes zero (i.e., the highest point of the jump). This occurs at the peak of the curve, where the vertical velocity changes from positive to negative. To calculate this time, you can use the equation for vertical velocity in projectile motion:

v = v0y - g * t

where:

v = vertical velocity at any time t

v0y = initial vertical velocity (in this case, the vertical velocity of the rider at the top of the ramp)

g = acceleration due to gravity (approx. 9.81 m/s²)

t = time elapsed since the rider left the ramp

At the peak of the jump, the vertical velocity becomes zero, so we can set v = 0 and solve for t:

0 = v0y - g * t

t = v0y / g

Substituting this value of t into the equation for height, we can find the maximum height:

y = y0 + v0y * (v0y / g) - (1/2) * g * (v0y / g)²

y = y0 + (v0y² / 2g)

Therefore, the maximum height achieved by the rider is given by the equation above. You can calculate this value using the given measurements and plug them into the equation to find the maximum height.

What is statistics?

Statistics is a branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organization of numerical data. It involves the use of methods and techniques to gather, summarize, and draw conclusions from data.

To find the highest point the rider achieved on a jump, we need to measure the rider's height at different points during the jump.

A. The two quantities we would measure for x and y would be:

x: the horizontal distance the rider travels during the jump

y: the vertical height of the rider at different points during the jump

B. The equation that describes the rider's motion during the jump would be a quadratic equation in the form of:

y = ax² + bx + c

Where:

a is the coefficient of the quadratic term and represents the acceleration due to gravity

b is the coefficient of the linear term and represents the initial velocity of the rider

c is the constant term and represents the initial height of the rider

C. To find the maximum height, we need to find the vertex of the parabola that represents the rider's motion.

The vertex is the highest point on the parabola and is located at the point (-b/2a, c - b²/4a).

To find the vertex, we need to measure the rider's height at least two different points during the jump.

The two points should be on either side of the vertex to ensure that we have captured the shape of the parabola correctly.

Answer:

The possible radius and height for the inside of the cylinder that meets the constraints are r = 4 cm and h = 9.4 cm.

Step-by-step explanation:

The formula for the volume of a cylinder is V = πr^2h, where V is the volume, r is the radius, and h is the height. We want to find a radius and height that will give us a volume between 475 and 480 cubic centimeters, with a diameter between 8 and 10 centimeters. First, we’ll use the lower limits of the constraints: a volume of 475 cubic centimeters and a diameter of 8 centimeters. The diameter is 8 centimeters, so the radius is 4 centimeters. We can plug in these values to the formula for volume and solve for h: 475 = 3.14 x 4^2 x h 475 = 50.24h h = 9.44 So a possible radius and height for the inside of the cylinder that meets the constraints are: r = 4 cm and h = 9.4 cm.

The inequality for "number t​ divided by 32 is at most 4. 25" is t/32 ≤ 4.25 and the solution is t ≤ 136

To write the word sentence as an inequality, we need to translate the words into mathematical symbols.

The phrase "a number t divided by 32" can be written as t/32. The word "is" can be translated as an equals sign, and "at most" can be translated as less than or equal to. Therefore, the word sentence "A number t divided by 32 is at most 4.25" can be written as:

t/32 ≤ 4.25

To solve the inequality, we can isolate the variable t by multiplying both sides by 32:

t ≤ 4.25 * 32

t ≤ 136

Therefore, the solution to the inequality is t is less than or equal to 136. This means that any value of t that is less than or equal to 136 will make the original inequality true. If t is greater than 136, then the inequality will be false.

Answer:

18.62π square inches

Step-by-step explanation:

To find the surface area of the cylinder, we need to find the area of each of its components and add them together. We can use the net of the cylinder to visualize its components and dimensions.

First, let's find the area of the top and bottom circles. We know the diameter of each circle is 3.8 inches, so the radius is half of that, or 1.9 inches. The formula for the area of a circle is A = πr^2, so:

A(top and bottom circles) = 2π(1.9 in)^2

= 2π(3.61 in^2)

= 7.22π in^2

Next, let's find the area of the curved surface of the cylinder. The height of the cylinder is labeled as 3 inches, which is also the height of the rectangle in the net. The length of the rectangle is the circumference of one of the circles, which is πd (where d is the diameter). So:

length of rectangle = π(3.8 in) = 11.96 in

The formula for the area of the curved surface of a cylinder is A = 2πrh, where r is the radius and h is the height. We can use the radius we found earlier and the height of 3 inches to calculate the area of the curved surface:

A(curved surface) = 2π(1.9 in)(3 in)

= 11.4π in^2

Finally, we can add the areas of the top and bottom circles and the curved surface to get the total surface area of the cylinder:

Total surface area = A(top and bottom circles) + A(curved surface)

= 7.22π in^2 + 11.4π in^2

= 18.62π in^2

Therefore, the surface area of the cylinder in terms of π is 18.62π square inches.

Answer: 3.45meters

Step-by-step explanation:

To find the range of the length of pipe that the plumber can cut, we need to write an absolute value inequality that expresses the condition that the length of the pipe must be within 0.09 meters of the required length. Let's call the required length L.

The plumber can cut a pipe that is within 0.09 meters of the required length, so the length of the pipe must be between L - 0.09 and L + 0.09. We can express this as:

|3.36 - L| ≤ 0.09

To solve this inequality, we need to consider two cases: when 3.36 - L is positive and when it is negative.

Case 1: 3.36 - L ≥ 0

In this case, the absolute value of 3.36 - L is equal to 3.36 - L. So we can write:

3.36 - L ≤ 0.09

Solving for L, we get:

L ≥ 3.36 - 0.09

L ≥ 3.27

Therefore, if 3.36 - L is positive, the length of the pipe must be greater than or equal to 3.27 meters.

Case 2: 3.36 - L < 0

In this case, the absolute value of 3.36 - L is equal to -(3.36 - L), or L - 3.36. So we can write:

L - 3.36 ≤ 0.09

Solving for L, we get:

L ≤ 3.36 + 0.09

L ≤ 3.45

Therefore, if 3.36 - L is negative, the length of the pipe must be less than or equal to 3.45 meters.

Putting these two cases together, we get:

3.27 ≤ L ≤ 3.45

Therefore, the range of the length of pipe that the plumber can cut is between 3.27 meters and 3.45 meters.
