Solve negative four and one third ÷ two and one fifth.

The perimeter of the triangle formed by the points B(7,-9), C(7,-2) and D(0,0) is 25.68 square units.

Perimeter is defined as the distance or the enclosed path that surrounds the 2-D shapes or polygon. The perimeter of a triangle is the sum of all the three sides of a triangle.

The perimeter of a triangle formed by the points B(7,-9), C(7,-2) and D(0,0) can be determined by finding the distance between two points.

The distance between two points A(x1,y1) and B(x2,y2).

√[(x2-x1)²+(y2-y1)²]

Therefore, BC = √(7-7)²+(-2+9)²

BC = √49

BC = 7 square units.

and CD = √(0-7)²+(0+2)²

CD = √53

CD = 7.28 square units.

and DB = √(7-0)²+(-9-0)²

DB = √130

DB = 11.40 square units.

Therefore, perimeter of triangle formed from given points is BC+CD+DB =  7+7.28+11.40 = 25.68 square units.

This problem is about "order of operations."  These are the rules we all agree upon that dictate which order we do mathematical operations.  We use the acronym PEMDAS to help remember them:

P - parentheses first, then:

E - exponents (powers, square roots, etc)

MD - multiplication and division (from left-to-right)

AS - addition and subtraction (from left-to-right)

The median of a set of numbers is the middle number in the set (after the numbers have been arranged from least to greatest) -- or, if there are an even number of data, the median is the average of the middle two numbers.

For example:

Find the median of the set {2,5,8,11,16,21,30} .

There are 7 numbers in the set, and they are arranged in ascending order.  The middle number (the 4 th one in the list) is 11.  So, the median is 11.

The center of a data set is also a way of describing the location. The two most widely used measures of the center of the data are the mean (average) and the median. To calculate the mean weight of 50 people, add the 50 weights together and divide by 50. To find the median weight of the 50 people, order the data, and find the number that splits the data into two equal parts. The median is generally a better measure of the center when there are extreme values or outliers because it is not affected by the precise numerical values of the outliers.

The simplified equation of the given statement = 1.08r.

Even though they also have different operations, adding and subtracting variables follow the same rule: while adding or subtracting terms with the same variables, either add or subtract the coefficients and leave the result with the variable. As an example, consider an addition.

The original cost of the new robotic toy is given as r.

The cost of the new robotic toy after a 8% markup is: c + 0.08r to show that 8% of r was being added to r to increase the price.

Because both numbers in the equation are related to the same variable, they can be added. When r is used alone, it is considered to be 1r.

= r + 0.08r

= 1r + 0.08r

= 1.08r

Step-by-step explanation:

We get the reflection of points T, U and V as T' = (0, 2), U' = (0, 1) and V' = (0, 4) over the x- axis.

We are given some coordinates:

T(0, - 2), U(2, - 1), V(3, - 4)

We have to first plot them on a graph.

Now, we have to reflect them over x - axis.

To reflect over x- axis, the x-coordinate remains the same, but the y-coordinate is taken to be the additive inverse.

For point T:

Additive inverse of - 2 = 2

T' = (0, 2)

For point U:

Additive inverse of - 1 = 1

U' = (0, 1)

For point V:

Additive inverse of - 4 = 4

V' = (0, 4)

Therefore, we get the reflection of points T, U and V as T' = (0, 2), U' = (0, 1) and V' = (0, 4) over the x- axis.

The equation to represent the relationship between Distance and Time will be 52y = x, where Speed remains constant

In the given question, it is said that the train runs along a distance of 156 miles, which takes 3 hours to complete.

The equation that represents the relationship between Speed, Distance, and Time is as follows :

=> Speed = Distance/Time

It is also stated that the train runs at the same speed so the Speed will be constant while deriving the relationship between Distance and Time.

First, we have to find the speed of the train with the given Distance & Time by the formula => S = D/T, where Speed = S, Distance = 156 miles, and Time = 3 Hours

=> S = 156/3 => S = 52 miles/hour

As we got our constant speed for the train, We can now find out the Distance Time relation of the train. By taking Distance = x, Time = y, Speed = 52 miles/hour

                     => 52 = x/y      => 52y = x

Hence, we get the relationship between Distance and Time where Speed is constant at 52 miles/hour

The degree measure for angle B is 28° and angle D is 62°.

We are given that:

∠ C = 90°

∠ B = ( 2 x + 10 )°

∠ D = ( 5 x + 17 )°

Now, using the angle sum property of a triangle, we get that:

∠B + ∠ C + ∠ D  = 180°

Substituting the values:

2 x + 10 + 90 + 5 x + 17 = 180

7 x + 117 = 180

7 x = 63

x = 63 / 7

x = 9

∠ B = ( 2 x + 10 )

∠ B = 2(9) + 10

∠ B = 18 + 10

∠ B = 28°

∠ D = ( 5 x + 17 )

∠ D = 5 (9) + 17

∠ D = 45 + 17

∠ D = 62°

Yes. It is a right-angled triangle.

The dot product, also known as the scalar product, is an algebraic operation that takes two sequences of numbers of equal length (often coordinate vectors) and outputs a single number. The dot product of two vectors' Cartesian coordinates is frequently used in Euclidean geometry. Although other inner products can be defined in Euclidean space, it is frequently referred to as the inner product (or, less frequently, projection product) of Euclidean space (see Inner product space for more).

The sum of the products of the matching entries of the two number sequences is the dot product, according to algebra. B, it is the result of adding the cosine of the angle between the two vectors and the Euclidean magnitudes of the two vectors.

The vectors that make up the triangle must first be located. The vertices are subtracted to achieve this.

QP=(2,0,-4)-(1,-3,-2)=(1,3,-2)

PR=(1,-3,-2)-(6,-2,-5)=(-5,-1,3)

RQ=(6,-2,-5)-(2,0,-4)=(4,-2,-1)

QP.PR = (1, 3, -2).(-5, -1, 3) = -5-3-6= -14

PR.RQ = (-5, -1, 3).(4, -2, -1) = -20+2-3 = -21

RQ.QP = (4, -2, -1).(1, 3, -2) = 4-6+2 = 0

Calculate the dot products to see if these vectors are perpendicular now.

They are perpendicular if the dot product of two vectors equals zero. As you can see, RQ.QP is zero in your triangle, which supports this. Consequently, a right-angled triangle results.

The slope intercept form of a line which passes through the points (-2, 5) and (6, -4)  is  y = (-9/8)x + 11/4.

According to the question.

A line passes through the two points (-2, 5) and (6, -4).

As we know that, the slope intercept formula y = mx + b is used when you know the slope of the line to be examined and the point given is also the y intercept (0, b). In the formula, b represents the y value of the y intercept point.

So, the slope of the line = -4 -5/(6 + 2) = -9/8

And, the slope intercept form of a line which passes through the points (-2, 5) and (6, -4) is given by

y = (-9/8)x + b

Since, the line passes through (-2, 5) and (6, -4). So, both the points must statisfy the above equation.

⇒ 5 = (-9/8)(-2) + b

⇒ 5 = 9/4 + b

⇒ b = 5 - 9/4

⇒ b = (20 - 9)/4

⇒ b = 11/4

Therefore, the slope intercept form of a line which passes through the points (-2, 5) and (6, -4)  is  y = (-9/8)x + 11/4.

A parabola refers to an equation of a curve, such that a point on the curve is equidistant from a fixed point, and a fixed line. The fixed point is called the focus of the parabola, and the fixed line is called the directrix of the parabola. Also, an important point to note is that the fixed point does not lie on the fixed line. A locus of any point which is equidistant from a given point (focus) and a given line (directrix) is called a parabola.
