Find the area of polygon with A(-5,-2) ,B (4,-2), C (4,-7) , D (-5,-7))?

Answer:

PLEASE READ! Is that 7 to the second power? if so, here is your answer: 49

Step-by-step explanation:

The difference between the sum of the measures of the interior angles in an octagon and the sum of the measures of the interior angles in a hexagon is 360°.

Interior angle refers to the angle inside a polygon that is formed by two of its adjacent sides. The sum of the measures of the interior angles of a polygon is given by the equation:

180°(n - 2)

where n is the number of sides

An octagon is a polygon that has 8 vertices and 8 sides. The sum of the measures of the interior angles of an octagon is:

180°(8 - 2) = 180°(6) = 1080°

On the other hand, a hexagon is a polygon that has 6 vertices and 6 sides. The sum of the measures of the interior angles of an octagon is:

180°(6 - 2) = 180°(4) = 720°

Subtracting the sum of the interior angles of the two polygons,

1080° - 720° = 360°

For the given situation, we can clearly say that the change in one quantity will cause a change in the second quantity as well.

Correlation is a relationship between the values ​​of two variables. A scatter plot is a useful tool for displaying data about two variables as a series of points in the x and y plane and determining whether there is a correlation between the variables.

Causality means that one event causes another. Causality can only be determined by well-designed experiments. In such experiments, similar groups receive different treatments, and the results of each group are examined.

From the above information, we concluded that a person's age and the number of cassette tapes he/she owns are correlated more he lives the more he buys the cassette tapes. So we can make relation from this,

Person's Age ∝ Number of Cassette

This clearly states that by increasing/changing one quantity we will increase/change the other quantity as well.

Similarly, now that they have a direct relation if we decrease the Age of the person, the number of Cassette's will also decrease. A positive correlation we can call it.

-439 is the value which is equivalent to (s circle t) (negative 7).

Given,

s(x) = 2 - x²

t(x) = 3x

We have to find the value which is equivalent to (s circle t) (negative 7)

That is,

(s circle t) (negative 7) : This is a notation for compound function.

A function that takes another function as an argument is referred to as a compound function.

s(t(-7)) is the alternative notation for this compound function, which means that the value obtained from the function t(-7) will be used in the function s. (x).

Now, let's calculate the value of t(-7):

That is,

t(x) = 3x

t(-7) = 3 × (-7) = -21

Next, apply the value of t(-7) for s(x)

That is,

s(x) = 2 - x²

s(t(-7)) = s(-21) = 2 - (-21)^2 = 2 - 441 = -439

That is, -439 is the value which is equivalent to (s circle t) (negative 7).

Answer:

       Co ordinate of A' = (1, -4)

       Co ordinate of B' = (3, 2)

       Co ordinate of C' = (4, -2)

Explanation:

The figure of the triangle is shown below.

 If we are finding image of the triangle about X-axis all the x -co-ordinates will remain same, but y co-ordinate will change it's sign.

So, co ordinate of A' = (1, -4)

       Co ordinate of B' = (3, 2)

       Co ordinate of C' = (4, -2)

The transformation applied to the parent function is vertical compression by a factor of 0.25.

In mathematics, functions can be manipulated algebraically to obtain graphs of functions through certain transformations. Such transformations are reflections of the x-axis or the y-axis. To flip a function f(x) on the x-axis, multiply the whole function by a negative value to get -f(x), and to flip a function f(x) on the y axis, f(-x ), specify the x variable with a negative value.

Vertical compression helps shrink features vertically. Vertical compression occurs when you multiply the function by a rational scaling factor. The base of the function graph remains the same even when the graph is compressed vertically. Only initial values are affected.

It is vertically compressed by a factor of 0.25.

Answer: (7y+237) / 8 = x

Step-by-step explanation:

So your equation is:
(2y+50) + (7x-248) + (5y-17) + (x+44)
First thing to do is combine all the like terms. Lets start with y. So that would be 2y + 5y= 7y and 50 + -17 is 33. The new equation is:
(7y + 33) + (7x-248) + (x+44)

Now we will combine the x. We will do -248+44= -204
and 7x+x= 8x.
Now our new equation is:

(7y + 33) + (8x+-204)
Now we can subtract 33 from -204. That is 237.
Now we have 7y+237 = 8x
To isolate x we need to divide by 8. That will give us this:
(7y+237) / 8 = x

The value of x if the sides are congruent is 3

The given parameters are

MN=6x-1 and MP=3x+8

For the sides to be congruent, then the following equation must be true

MN = MP

This gives

6x - 1 = 3x + 8

Collect the like terms

6x - 3x = 1 + 8

Evaluate the like terms

3x = 9

Divide by 3

x = 3

Hence, the value of x if the sides are congruent is 3

Step-by-step explanation:

The negative solution of the given statement is - 4.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Let the unknown number be 'n'.

∴ When 32 is subtracted from the square of a number, is n² - 32 and the result is 4 times the number which is equal to 4n,

So, n² - 32 = 4n.

n² - 4n - 32 = 0.

n² - 8n + 4n - 32 = 0.

n(n - 8) + 4(n - 9) = 0.

(n - 8)(n + 4) = 0.

n - 8 = 0 Or n + 4 = 0.

n = 8 Or n = - 4.

If Lee is laying out a design for the tiles of a section of his bathroom floor and he will use 1 white tile for every 6 black tiles to have a total of 28 tiles in the design then the number of white and black tiles Lee will use is equal to 4 and 24 respectively.

The number of white and black tiles Lee will use can be determined by using an algebraic expression.

As 1 white tile is used for every 6 black tiles, an algebraic expression can be represented as,

x + 6x = 28

By solving the value of x, the number of each type of tile that Lee will use can be calculated,

x + 6x = 28

7x = 28

x = 28 ÷ 7

x = 4

As there is one white tile for every six black tiles,

White tiles = 1(x) = 1(4) = 4

Black tiles = 6(x) = 6(4) = 24

Hence the number of white tiles Lee will use is equal to 4 and the number of black tiles Lee will use is equal to 24.

The conditional probability formula for P(B | A) has been derived from two dependent events P(A and B).

When the outcome from one event influences the outcome of the other, two events are referred to as dependent.

Derivation of conditional probability from two dependent events P(A and B) is-

The probability multiplication rule is used to derive the conditional probability formula, P(A and B) = P(A)×P(B|A).

This rule is also known as P(AB). The Union symbol (∪) represents "and," as in event A occurring and event B occurring.

Step 1: Write the multiplication rule down:

           P(A and B) = P(A)*P(B|A)

Step 2: P(A) divides both sides of the equation:

           P(A and B) / P(A) = P(A)*P(B|A) / / P(A)

Step 3: On the right side of the equation, cancel P(A):

           P(A and B) / P(A) = P(B|A)

Step 4: Rewrite the equation as follows:

           P(B|A) = P(A and B) / P(A)

Therefore, P(B | A) conditional probability formula is compiled from two dependent events P (A and B).
