A rational equation is an equation that includes one or more fractions with polynomials. It can be solved by cancelling common factors between the numerator and the denominator, and then solving the resulting equation. It is important to note that when cancelling common factors, one must always check that the original equation is still satisfied.

To solve this rational equation that simplifies to linear, you need to solve for v. To do this, first multiply both sides by the denominator:

6(v-8) = 5

Then add 8 to both sides to get rid of the variable in the denominator:

6v - 48 = 5

Finally, add 48 to both sides to isolate the variable v:

6v = 53

Finally, divide both sides by 6 to solve for v:

v = 53/6 = 8.83

The amount after 3 years with an interest rate of 7.5% will be $1,242.3.

A loan or deposit's interest is computed using the starting principle and the interest payments from the ago decade as compound interest.

We know that the compound interest is given as

A = P(1 + r)ⁿ

Where A is the amount, P is the initial amount, r is the rate of interest, and n is the number of years.

Assume the yearly interest rate is 7.5% and the interest is compounded once a year.

If the amount of investment is $1,000 and the amount after 3 years is given as,

A = P(1 + r)ⁿ

A = $1,000 × (1 + 0.075)³

A = $1,000 × (1.075)³

A = $1,000 × 1.24229

A = $1,242.3

The amount after 3 years with an interest rate of 7.5% will be $1,242.3.

In total, they have 6000 grams of sand.

What are basic arithmetic operations?

The basic arithmetic operations are the four fundamental mathematical operations used to manipulate numerical values. They are addition, subtraction, multiplication, and division.

To solve the problem, we need to know the conversion factor between kilograms and grams, which is 1 kilogram = 1000 grams.

First, we can find out how many grams of sand Lucas has in his bucket. We are given that he has 2 kilograms of sand, so we can use the conversion factor to convert kilograms to grams:

2 kilograms x 1000 grams/kilogram = 2000 grams

Therefore, Lucas has 2000 grams of sand in his bucket.

Next, we can find out how many grams of sand Mac has in his bucket. We are given that he has 4 kilograms of sand, so we can use the conversion factor again:

4 kilograms x 1000 grams/kilogram = 4000 grams

Therefore, Mac has 4000 grams of sand in his bucket.

To find out the total amount of sand they have in grams, we can add the amount of sand each of them has:

2000 grams + 4000 grams = 6000 grams

Therefore, in total, they have 6000 grams of sand.

The missing degrees in the circle are 260 degrees.

What is circle ?

A circle is a geometrical shape that represents a set of points in a plane that are equidistant from a fixed point called the center. The distance from the center to any point on the circle is called the radius, and the diameter of the circle is the distance across its widest point, passing through the center.

To find the missing degrees in the circle, we need to use the fact that the sum of the central angles in a circle is equal to 360 degrees.

In this circle, we have two central angles: one measuring 100 degrees and the other measuring x degrees. We also know that the sum of these two central angles is equal to 360 degrees.

Therefore, we can set up the following equation:

100 + x = 360

To solve for x, we can subtract 100 from both sides:

x = 260

Therefore, the missing degrees in the circle are 260 degrees.

The radian measure of 180 degrees is [tex]\pi \\[/tex] radians.

[tex]2\pi^c = 360^\circ = \text{Full circumference}[/tex]

The superscript 'c' shows angle measured is in radians.

If radius of the circle is of r units, then:

[tex]1^c \: \rm covers \: \dfrac{circumference}{2\pi} = \dfrac{2\pi r}{2\pi} = r\\\\or\\\\\theta^c \: covers \:\:\: r \times \theta \: \rm \text{units of arc}[/tex]

We are given that;

Radius=5units

Radian=180 degrees

Now,

The arc length of a circle is given by the formula:

arc length = (r * theta)

where r is the radius of the circle and theta is the angle in radians subtended by the arc at the center of the circle.

We know that the radius of the circle is 5 units, and we want to find the radian measure of an arc that subtends an angle of 180 degrees.

Since 180 degrees is half of a full circle, the arc length of this arc will be half of the circumference of the circle:

arc length = (1/2) * 2 * pi * r

          = pi * r

Plugging in r = 5, we get:

arc length = pi * 5 = 5pi

Now we can use the formula for arc length to find the radian measure of the arc:

arc length = r * theta

5pi = 5 * theta

theta = pi

Therefore, by the arc length the answer will be [tex]\pi[/tex] radians.

As a result, the length of the second rectangle is 22.5 inches.

Every square is also a rectangle because a square is a parallelogram with all particular corners at right angles. Yet not all rectangles are squares; for a rectangle to be a square, all of its sides must be the same length.

We can infer that the two rectangles may have a similar shape but differ in size because we can see how similar they are to one another.

By using the fact that the ratio of the adjacent angles of two comparable rectangles is the same, we can determine the length of the following rectangle.

Let x be the second rectangle's length. Then we can establish a ratio:

In its simplest radical form, the area of the right triangle is 8sqrt(3) square feet.

How is area determined?

The length of the other leg of the right triangle can be determined using the Pythagorean theorem:

[tex]a^2 + b^2 = c^2[/tex]

where the hypotenuse is c and the triangle's legs are a and b.

We are aware that the hypotenuse c is 8 feet long and that leg an is 4 feet long. Let's work out the answer for the opposite leg's length, b:

[tex]b^2 = c^2 - a^2\sb^2 = 8^2 - 4^2\sb^2 = 64 - 16\sb[/tex]

[tex]sqrt(48) = 4sqrt(3) foot where 2 = 48 b[/tex]

Given that we know the lengths of both legs, we can use the following formula to get the triangle's area:

[tex](1/2) * Base * Height = Area[/tex]

We may use the 4 ft leg as the base and the 4sqrt(3) ft leg as the height since one leg is 4 ft and the other is 4sqrt(3) ft:

The value of the angles of the parallelogram are 72 degree and 108 degree.

A quadrilateral with the opposing sides parallel is known as a parallelogram. It has numerous crucial traits, including:

A parallelogram has equal-length opposite sides. A parallelogram has opposite angles that are equally sized. A parallelogram's diagonals cut each other in half. A parallelogram is divided into four equal-sized triangles by its diagonals. A parallelogram's internal angles add up to 360 degrees. A parallelogram is classified as a rectangle if it also contains four right angles, making it a rectangle-shaped parallelogram.

Let us suppose the smaller angle = x.

The other angle is thus x + 36.

In a parallelogram the opposite angles are equal thus:

x + x + x + 36 + x + 36 = 360

4x + 72 = 360

4x = 288

x = 72

The value of x + 36 = 72 + 36 = 108

(b) The dot product of u and v is -2k^2+5k^2+k^2=4k^2. For u and v to be orthogonal, 4k^2=0, which means k=0.

Therefore, in both cases, the vectors are orthogonal when k=0.

Let AB and AC be vectors joining the points A(0,-1), B(1,-2), and C(4,1), respectively. Then,

AB = (1-0, -2-(-1)) = (1,-1)

AC = (4-0, 1-(-1)) = (4,2)

The cosine of the angle between two vectors u and v is given by the dot product of u and v divided by the product of their magnitudes, i.e., cos(theta) = (u.v)/(|u||v|).

(a) Cosine of angle A = cos(BAC) = (AB.AC)/(|AB||AC|) = (1(4) + (-1)(2))/sqrt(2^2+1^2 * 4^2+2^2) = 2/3

Cosine of angle B = cos(CAB) = (AC.AB)/(|AC||AB|) = (4(1) + 2(-1))/sqrt(4^2+2^2 * 2^2+1^2) = 1/3

BC = (8-4, 1-3, -1-0) = (4, -2, -1)

AC = (8-3, 1-0, -1-2) = (5, 1, -3)

The cosine of the angle between two vectors u and v is given by the dot product of u and v divided by the product of their magnitudes, i.e., cos(theta) = (u.v)/(|u||v|).

Answer:

I CAN NOT SEE THAT OML

Step-by-step explanation:

The function f(x) in completely factored form is (4x+1)(5x-1)(x+5).

To write f(x)=20x^(3)+44x^(2)-17x-5 in completely factored form, we can use synthetic division with the given zero of (-(5)/(2)).

Step 1: Set up the synthetic division with the given zero and the coefficients of the polynomial.

(-(5)/(2)) | 20  44  -17  -5
         |______________

Step 2: Bring down the first coefficient, 20, and multiply it by the given zero.

(-(5)/(2)) | 20  44  -17  -5
         |     -50
         |______________
         | 20

Step 3: Add the result of the multiplication to the next coefficient and repeat the process until all coefficients have been used.

(-(5)/(2)) | 20  44  -17  -5
         |     -50   3   10
         |______________
         | 20  -6  -14   5

Step 4: The last number in the bottom row is the remainder. If it is zero, then the given zero is a factor of the polynomial. In this case, the remainder is 5, so (-(5)/(2)) is not a factor of f(x).

Since (-(5)/(2)) is not a factor of f(x), we cannot use synthetic division to write f(x) in completely factored form. Instead, we can use factoring to find the factors of f(x).

f(x) = 20x^(3)+44x^(2)-17x-5

= (4x+1)(5x-1)(x+5)

Therefore, f(x) in completely factored form is (4x+1)(5x-1)(x+5).
