What is the degree of the polynomial 7x³ 5x 4x³ 2x²?

A straight line is a boundless one-dimensional figure that has no breadth. It is a combination of boundless points joined on both sides of a point. A straight line does not have any loop in it. If we draw an angle between any two points on a straight line, we always get 180°.

A straight line can be formed between two points but both ends extend to infinity. A straight line is a figure created when two points A ([tex]x_{1} , y_{1}[/tex]) and B ([tex]x_{2} , y_{2}[/tex],) are connected with the shortest distance between them, and the line ends are extended to infinity.

The equation in point-slope form for the line passing through (3, -8) with a slope of -3 is y = -3x + 1

What is the slope?

The slope of a line is a measure of its steepness. Mathematically, the slope is calculated as "rise over run" (change in y divided by change in x).

The point-slope form of the equation of a line is:

y - y1 = m(x - x1)

where (x1, y1) is a point on the line and m is the slope.

We are given that the line passes through the point (3, -8) and has a slope of -3, so we can substitute these values into the point-slope form:

y - (-8) = -3(x - 3)

Simplifying the equation, we get:

y + 8 = -3x + 9

Subtracting 8 from both sides, we get:

y = -3x + 1

Therefore, the equation in point-slope form for the line passing through (3, -8) with a slope of -3 is:

y - (-8) = -3(x - 3)

which simplifies to:

y + 8 = -3x + 9

or in slope-intercept form:

y = -3x + 1

Hence, the equation in point-slope form for the line passing through (3, -8) with a slope of -3 is y = -3x + 1

The required equation that represents the relationship between b and e exists m<b + m<e = 180.

Two angles are called supplementary when their measures add up to 180 degrees.

If the sum of two angles is 180 degrees then they are said to be supplementary angles, which form a linear angle together. Whereas if the sum of two angles is 90 degrees, then they are said to be complementary angles, and they form a right angle together.

The required equation that represents the relationship between b and e exists m<b + m<e = 180

From the given diagram, we can see that the line x and y are cut by a transversal. This shows that the following statements exists true;

m<b and m<g exists supplementary

i.e m<b + m<g = 180

Also m<b and m<f are equal (alternate interior angle)

m<b = m<d (vertically opposite angle)

Also, since m<d and m<e are supplementary angles (angle on a straight line), then m<b and m<e are also supplementary.

Therefore, the required equation that represents the relationship between b and e exists m<b + m<e = 180.

The right triangle in question 3 have the value of m = 10√2 and n = 10 using the trigonometric ratio of sine and cosine of the angle 45°.

The trigonometric ratios involves the relationship of an angle of a right-angled triangle to ratios of two side lengths. Basic trigonometric ratios includes; sine cosine and tangent.

Considering the angle 45° for the right triangle, recall that sin 45° and cos 45° are both equal to √2/2

sin 45° = 10/m {opposite/hypotenuse}

√2/2 = 10/m

m = 20/√2 {cross multiplication}

m = 20/√2 × √2/√2 {rationalize}

m = 20√2/2

m = 10√2

cos 45° = n/m {adjacent/hypotenuse}

√2/2 = n/10√2

n = 10(√2)²/2

n = 10 × 2/2

n = 10

Step-by-step explanation:

One of the important theorems in the field of geometry that deals with the properties of triangles are called the Mid- Point Theorem.

The theory of midpoint theorem is used in coordinate geometry, stating that the midpoint of the line segment is an average of the endpoints. The ‘x’ and the ‘y’ coordinates must be known for solving an equation using this theorem. The Mid- Point Theorem is also useful in the fields of calculus and algebra.

Mid-Point Theorem Statement

The midpoint theorem states that “The line segment in a triangle joining the midpoint of any two sides of the triangle is said to be parallel to its third side and is also half of the length of the third side.”

Mid-Point Theorem Proof

If a line segment adjoins the mid-point of any two sides of a triangle, then the line segment is said to be parallel to the remaining third side and its measure will be half of the third side.

Consider the triangle ABC, as shown in the above figure,

Let E and D be the midpoints of the sides AC and AB. Then the line DE is said to be parallel to the side BC, whereas the side DE is half of the side BC; i.e., DE || BC

DE = (1/2 *  BC).

Mid-Point Theorem Formula

In Coordinate Geometry, the midpoint theorem refers to the midpoint of the line segment. It defines the coordinate points of the midpoint of the line segment and can be found by taking the average of the coordinates of the given endpoints. The midpoint formula is used to determine the midpoint between the two given points.

If P1(x1, y1) and P2(x2, y2) are the coordinates of two given endpoints, then the midpoint formula is given as:

Midpoint = [(x1 + x2)/2, (y1 + y2)/2]

The converse of Mid-Point Theorem

The converse of the midpoint theorem states that ” if a line is drawn through the midpoint of one side of a triangle, and parallel to the other side, it bisects the third side”

Formula to Find the Midpoint

The Midpoint Formula is given as,

(x, y) = [(x1 + x2)/2, (y1 + y2)/2]

So B requires 8 more days to complete the work.

Lets assume total unit of work to be= 30units

A can finish the work in= 15 days

B can finish the work in= 10 days

A work efficiency  can be calculated by formula

Efficiency=  Total work/ Number of days

A efficiency= 30/15

30 divided by 15

A= 2

Similarly for B we can calculate its work efficiency

B efficiency= 30/10

30 divided by 10.

B= 3

A work for 3 days and leaves

work done by A = 2*3 = 6 unit

2 is A work Efficiency  and we multiply by 3 that is number of days A worked on.

 work done formula = Efficiency* Number of days  

Now we calculate the remaining work

We subtract the total work by the work done by A

Remaining work= 30-6= 24 unit

so the days required by B is = Work Left divided by B efficiency

B days= 24/ 3 = 8

Answer:

I assumed that the square roots were not nested for this problem, which means I put √125 beside √20 - (-3).

Step-by-step explanation:

Start this problem off by applying an inversive rule: x - (-y) = x + y

[tex]=14\sqrt{20+3}\sqrt{125}[/tex]

Now, simplify √125 into a radical.

[tex]= \sqrt[5]{5}[/tex]

Now that the previous number is a radical, this is what the expression should look like:

[tex]=14\sqrt{20+3}\times 5\sqrt{5}[/tex]

Next, we multiply the numbers together. Borrow the ^5 from the radical, then regroup like terms.

[tex]14\times 5 = 70\\=70\sqrt{20+3}\sqrt{5}\\=70\sqrt{5}\:\times \sqrt{20+3}[/tex]

Last of all, we must apply the radical rule, which states that if there are two radicals, radical X and radical Y, these radicals will combine into one, and then will be multiplied by each other. However, note that the radicals cannot equal 0.

[tex]\sqrt{5}\sqrt{23}=\sqrt{5\times 23}[/tex]

Now, since the radicals are combined, multiply them together. 5 times 23 is 115, so combine the square root, and that will be your final answer. :)
