Answer:

C(x) = 25 + 1.5x

Step-by-step explanation:

A function is a mathematical equation that describes how two variables are related. To write a function that models the cost of having a carpet installed, we can use the information provided in the problem.

The cost of having a carpet installed is:

C(x) = 25 + 1.5x

Where C(x) represents the total cost of the carpet installation and x represents the number of square yards of carpet.

25 is a fixed cost for delivery , and $1.5 is cost per sq yard.

So, C(x) = 25 + 1.5x this function is representing the cost of having a carpet installed in x sq yard.

Answer:

The third side of the triangle must be greater than 4 and less than 19. This follows from the Triangle Inequality Theorem, which states that the sum of any two sides of a triangle must be greater than the third side, and the difference between any two sides of a triangle must be less than the third side. Therefore, the third side must be greater than 4 (5 + 4) and less than 19 (14 - 4).

Triangle MNO with sides m = 20, n = 14 and angle m ∠ M = 51° can have two possible configurations.

In this problem we have the knowledge of two sides and an angle of triangle MNO, where angle M is opposite to side m. First, determine the possible values for angle N by law of sine:

n / sin (m ∠ N) = m / sin (m ∠ M)

14 / sin (m ∠ N) = 20 / sin 51°

sin (m ∠ N) = (14 / 20) · sin 51°

sin (m ∠ N) = 0.544

The shorter side of the triangle will be opposite to 30° angle and larger side will be opposite to 90° angle .

A right triangle, also known as a right-angled triangle, right-perpendicular triangle, orthogonal triangle, or previously rectangled triangle, is a triangle with one right angle, or two perpendicular sides. The foundation of trigonometry is the relationship between the sides and various angles of the right triangle.

The side opposite the smallest angle is the one that is the shortest. The shortest side is opposite the angle that you already know to be the shortest.

The side opposite the right angle is always the hypotenuse of a right triangle. In a right triangle, it is the longest side.

The area of a triangle can be found by using the formula A = 1/2bh, where b is the base of the triangle and h is the height of the triangle. To find the area of a triangle in square units, you would need to multiply the base and the height of the triangle and then divide the result by 2.Once you have these two measurements, simply plug them into the formula and calculate the area.

To calculate the area, we need to first measure the base and the height. Once we have the measurements, we can calculate the area by multiplying the base by the height and then dividing by two. For example, if the base is 8 units and the height is 6 units, the area of the triangle will be 24 square units (A = 1/2*8*6 = 24).

If the rectangular area has maximum area, the dimension of the rectangular area is 62.5 m×62.5 m. The area is 3,906.25 square meters.

To enclose a rectangular area with one side bordered by a stream, Farmer Mei can use the remaining 250 meters of fence to form the other three sides of the rectangle. Since the rectangle has two sides of equal length (the width and the height), we can set up the equation:

2L + 2W = 250

where L represents the length of the rectangle and W represents the width.

Solving for one variable in terms of the other:

W = 250/2 - L

The area of the rectangle is given by the formula:

A = L×W

Now, we can substitute the value of W from the above equation into this one to get:

A = L × (250/2 - L)

A = 125L - L²

To find the maximum area, we need to take the derivative of A with respect to L and set it equal to 0.

dA/dL = 250/2 - 2L = 0

Which gives us the value of L = 125/2 = 62.5m

Now, we can substitute this value of L back into the equation for W to find the width of the rectangle:

W = 250/2 - 62.5 = 62.5m

Therefore the dimensions of the rectangle is 62.5m x 62.5m and the maximum area that can be enclosed is 62.5m x 62.5m = 3,906.25 sq m.

Answer:

It equals one

Step-by-step explanation: Anything that has the exponent of 0 will always equal one

The side lengths of a 45-45-90 triangle can be found using side ratios or the formula that the length of hypotenuse is root two times the length of each leg which is equal.

A 45-45-90 triangle is a special type of right triangle that has two angles that measure 45 degrees and one angle that measures 90 degrees. This triangle has a unique relationship between its side lengths.

The length of the hypotenuse (the side opposite the 90-degree angle) is equal to √2 times the length of one of the legs (the two sides that are congruent and form the 45-degree angles).

The length of each leg is equal to the length of the hypotenuse divided by √2.

For example, if the hypotenuse of a 45-45-90 triangle measures 8 units, then one leg measures 8/√2 = 8/1.4142 = 5.6568 units, and the other leg measures also 8/√2 = 8/1.4142 = 5.6568 units.

Another way to find the side lengths of a 45-45-90 triangle is to use the side ratios. The ratio of the sides in a 45-45-90 triangle is 1:1:√2, so if you know the length of one side, you can find the length of the other sides using these ratios.

It's important to keep in mind that a 45-45-90 triangle is a special type of triangle and its side lengths can be found using the formulas and ratios mentioned above. Regular triangles, such as a 30-60-90 triangle, have also similar relationships between their sides.

The Factor Theorem states that if a polynomial is divided by (x-a) then the remainder is equal to zero if and only if (x-a) is a factor of the polynomial.

To solve the Factor Theorem, first you need to determine the polynomial and the value of (x-a).

Then you divide the polynomial by (x-a). To do this, use synthetic division. Synthetic division is a shorthand way of dividing a polynomial by a linear factor.

If the remainder is 0, then the polynomial is divisible by (x-a). If the remainder is not 0, then (x-a) is not a factor of the polynomial.
