(-3/4) - 2/5

So there are two possible triangles:

(10.5, 35.5, 37) and (35.5, 10.5, 37).

Let's call the length of the shorter leg x. Then, the longer leg would be 3x - 3, and the hypotenuse would be 4x - 7.

Using the Pythagorean theorem, we have:

x^2 + (3x - 3)^2 = (4x - 7)^2

Expanding and simplifying, we get:

x^2 + 9x^2 - 18x + 9 = 16x^2 - 56x + 49

Combining like terms, we have:

7x^2 - 74x + 40 = 0

Using the quadratic formula, we find the solutions for x:

x = (74 ± √(74^2 - 4 * 7 * 40)) / (2 * 7)

x = (74 ± √(2744 - 560)) / 14

x = (74 ± √2184) / 14

x = (74 ± 46.56)/14

x = (35.5, 10.5)

So there are two possible triangles:

(10.5, 35.5, 37) and (35.5, 10.5, 37).

These are the two solutions for the lengths of the sides of the triangle.

|8x - 7| < 9

The absolute value part can be "broken" into two parts, these are:

(8x - 7) < 9

(8x - 7) > -9

Now we need to solve these two.

The first one gives:

8x - 7 < 9

8x < 9 + 7

8x < 16

x < 16/8

x < 2

The other gives:

The domain and range of function f(x) = 2/3x² are respectively, real numbers and non-negative numbers

The domain of a function is the set of all input values (independent variable) for which the function is defined and produces a valid output (dependent variable).

The range of a function is the set of all possible output values of the function. It represents the set of all possible values of the dependent variable.

Given that,

The domain of the function f(x) = 2/3x² is all real numbers except x = 0, since division by 0 is undefined.

The function f(x) = 2/3x²

The range of the function f(x) = 2/3x² is all non-negative real numbers.

It is because for any real number x,

the value of 2/3x² will always be non-negative.

To see this, consider the case where x > 0.

In this case, 2/3x² is positive,

and for x < 0, 2/3x² is still positive.

So, the domain of the function f(x) = 2/3x² is all real numbers except x = 0 and the range of the function is all non-negative real numbers.

Let: x = the distance from the base of the ladder to the base of the wall

y = the distance from the tip of the ladder to the base of the wall, we have:

x² + y² = 15²

y² = 15² - 5² = 225 - 25 = 200 => y = 14.14 ft

The Central Limit Theorem states that the distribution of the sample mean approaches a normal distribution as the sample size increases, regardless of the shape of the underlying population distribution.

If the sample size is large enough (typically, n >= 30), we can assume that the sample mean is approximately normally distributed with mean equal to the population mean and standard deviation equal to the population standard deviation divided by the square root of the sample size.

Therefore, if we know the population mean and standard deviation, we can calculate the probability that the sample mean will be greater than 3,011.76 or less than 2,988.24. Let's denote the population mean as mu and the population standard deviation as sigma. Then, the standard deviation of the sample mean is sigma / sqrt(n), where n = 1000 is the sample size.

We can standardize the sample mean using the z-score formula:

z = (x - mu) / (sigma / sqrt(n))

where x is the sample mean.

For the sample mean to be greater than 3,011.76, we have:

z = (3,011.76 - mu) / (sigma / sqrt(n)) > 0

And for the sample mean to be less than 2,988.24, we have:

z = (2,988.24 - mu) / (sigma / sqrt(n)) < 0

To find the probability, we need to find the area under the standard normal curve to the right of z for the first case, and to the left of z for the second case. These probabilities can be found using a standard normal table or a statistical software package.

Unfortunately, without knowledge of the population mean and standard deviation, it is not possible to determine the probability that the sample mean will be greater than 3,011.76 or less than 2,988.24.

The surface area and weight of the cylinder is 45.1805 in² and 11.107 lbs respectively.

A cylinder is a three-dimensional geometric shape that has two parallel circular bases and a curved lateral surface connecting the bases. The bases are located at opposite ends of the cylinder, and they have the same diameter. The lateral surface is a rectangle that has been bent around the circumference of the circular bases.

The height of a cylinder is the distance between the two bases, and the diameter of the bases is the distance across the circle through its center. The volume of a cylinder can be calculated by multiplying the area of one of its bases by its height. The formula for the volume of a cylinder is:

V = πr²h

where r is the radius of the circular base and h is the height of the cylinder.

Cylinders are commonly used in many real-world applications, such as in the design of pipes, cans, and other containers. They are also commonly used in mathematics and physics, where they can serve as models for objects with cylindrical symmetry, such as pipes and wires.

In summary, a cylinder is a three-dimensional shape with two parallel circular bases and a curved lateral surface connecting the bases. The height of the cylinder is the distance between the bases, and its volume can be calculated using the formula V = πr²h. Cylinders are commonly used in real-world applications and in mathematics and physics.

The following formula can be used to determine the cylinder's volume:

V = π × r² × h = π × (d/2)² × h = π × (1.35²) × 7.45 = 42.63374 in³

The following formula can be used to get the cylinder's surface area:

A = 2πr² + 2πrh = 2π × r² + 2π × r × h = 2π × (1.35²) + 2π × 1.35 × 7.45 = 45.1805 in²

The cylinder's weight can be determined using the formula below:

W = d × V = 0.259 lbs/in³ × 42.63374 in³ = 11.107 lbs.

A scale model of a regulation-sized gymnasium that is 12 inches long would be 10 inches wide.

To determine the width of a scale model of a regulation-sized gymnasium, you need to determine the scale factor used to create the model. The scale factor is the ratio of the size of the model to the size of the actual object.

In this case, the length of the model is 12 inches, while the length of the actual gymnasium is 100 feet, or 1200 inches. So, the scale factor is: 12/1200 = 1/100.

To find the width of the model, you would multiply the width of the actual gymnasium, 80 feet, by the scale factor, 1/100. This gives you a width of:
