Answer:

M' : ( -9,9)

N' : (9, 9)

P' :  ( -9,-9)

Step-by-step explanation:

Dilation if not fraction means multiply or bigger

Answer:

The median is 8.

How you get that is that you have to order these from smallest to biggest.

0,3,8,8,11,13,14

Next, you cut one from each side until you get one single number left. If you get two, then you add them together and divide it by 2.

Answer:

the vertex  of 3x^2-12+8 is (2,-4)

Answer:

(x + 1)(x + 2)(2x + 1)(x - 3).

Step-by-step explanation:

From the leading and last coefficients, 2 and -6  the values +/- 1, +/-2 , +/- 3 could be roots of this equation ( well, up to 4 of them).

Try x = 1:

f(1) = 2(1)^4 + 1^3 - 14(1)^2 - 19(1) - 6 = -36 so its not 1.

f(-1) = 2 - 1 - 14 + 19 - 6 = 0 do x = -1 is a root.

Therefore (x + 1) is a factor  (By the factor theorem)

Try x = 2:

f(2) =  32 + 8 -56 - 38 - 6 = -6o so x =2 not a root.

f(-2) = 32 - 8 - 56 + 38 - 6 = 0 so x = -2 is a root and (x + 2) is a factor.

(x + 1)(x + 2) = x^2 + 3x + 2.

Long division:

                        2x^2 - 5x - 3   <-----------Quotient

                      --------------------------------------------

x^2 + 3x + 2 )     2x^4  +   x^3   -14x^2 -  19x  -  6

                          2x^4  + 6x^3 +  4x^2  

                                      -5x^3  - 18x^2 - 19x

                                      -5x^3  - 15x^2 - 10x

                                                      -3x^2 - 9x  - 6

                                                      -3x^2  - 9x - 6

                                                       .......................

2x^2 - 5x - 3 = (2x + 1)(x - 3)

So Finally,   the factors are (x + 1)(x + 2)(2x + 1)(x - 3).

Answer:

80 sq ft

Step-by-step explanation:

this is a trapezoid and the formula for area is:

1/2 x height x (sum of the bases, which are parallel)

A = 1/2(10)(10+6)

= 5(16)

A' = (4, 3) B' = (7, 9) C' = (10, 5)

Step-by-step explanation:

Basically take the points you are given and add the "new" translation to your new points.

For example, A is (1, 1). So you can use your translation points to get (1+3, 1 + 2), or (4, 3)

Answer:

27 and 77

Step-by-step explanation:

Given

Let

[tex]n \to[/tex] number

[tex]n\ \%\ 2 = 1[/tex]

[tex]n\ \%\ 25 = 2[/tex]

[tex]n <100[/tex]

Required

Find n

[tex]n\ \%\ 2 = 1[/tex] implies that the number is odd and the possible solutions are:

[tex]\{3,5,7,9,......99\}[/tex]

The possible solutions to [tex]n\ \%\ 25 = 2[/tex] are:

[tex]\{27,52,77\}[/tex]

Testing 27, 52 and 77 with [tex]n\ \%\ 2 = 1[/tex], we have:

[tex]27\ \%\ 2 = 1[/tex] --- true

[tex]52\ \%\ 2 = 0[/tex] ---- false

[tex]77\ \%\ 2 = 1[/tex] --- true

Hence, the possible numbers are 27 and 77

Answer:

x = 10/7 or x = -10/7

Step-by-step explanation:

By using the completing the squares method, we have to divide the coefficient of the x term by 2, square it and add to both sides

From what we have here, the coefficient of the x term is 0

Thus, we have it that;

0 = 100 - 49x^2

We can proceed to use the difference of two squares here;

Whereby;

a^2 - b^2 = (a-b)(a + b)

0 = (10-7x)(10+7x)

10 - 7x = 0 or 10 + 7x = 0

7x = 10 or 7x = -10

x = 10/7 or x = -10/7

Answer:

The answer is 0

Answer:

BC ≈ 20.9

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

BC² + AC² = AB²

BC² + 7² = 22²

BC² + 49 = 484 ( subtract 49 from both sides )

BC² = 435 ( take the square root of both sides )

BC = [tex]\sqrt{435}[/tex] ≈ 20.9 ( to the nearest tenth )

Step-by-step explanation:

21x.30=6.3

21-6.3= 14.7

If  shirt cost $21 last month and the price decreased by 30% then the new price is $14.7.

percentage, a relative value indicating hundredth parts of any quantity.

Given that a  shirt cost is $21 last month.

The  price decreased by 30% in this month.

We have to find the new price.

To find this we have to find 30 percentage of 21.

Convert 30 % to decimal value by dividing with 100 and then multiply the decimal value with $21.

30/100× 21

0.3×21

$6.3

So the amount decreased is $6.3

The new price we get by subtraction $6.3 from $21.

21-6.3

New price = $14.7

Hence, if  shirt cost $21 last month and the price decreased by 30% then the new price is $14.7.

The equation -4x + 1 = 5x + 4 can be used to form a system of linear equations

The solution of x is x = -0.33

The equation is given as:

-4x + 1 = 5x + 4

Split the equation into a system of equations

y =-4x + 1

y = 5x + 4

Next, we plot the graph of both equations

From the graph (see attachment), we have the solution to be:

(x,y) = (-0.33, 2.33)

Remove the y value

x = -0.33

Hence, the solution of x is x = -0.33

Answer:

V = pi * R^2 * h

R = (V / (pi * h))^1/2 = (141.3 / (3.14 * 5))^1/2 = 3 cm

The radius of the cylinder is 3 cm.

Given,

The volume of the cylinder is 141.3 cubic centimeters.

We need to find what is the approximate radius of the cylinder.

Use 3.14 for the approximation of pi.

It is given by:

V = π r² h

h = height of the cylinder

r = radius of the cylinder.

We have,

V = 141.3 cm³

π = 3.14

h = 5 cm

V = π r² h

141.3 = 3.14 x r² x 5

141.3 / 3.14 x 5 = r²

r² = 9 cm²

r = 3 cm

Thus the radius of the cylinder is 3 cm

==========================================================

Explanation:

We have 3 even values (2,4, and 6) so this is the number of choices we have for the units digit. Recall that a number is even if the units digit is 0,2,4,6 or 8.

Once we have the units digit selected, we have 6-1 = 5 choices for the first slot, 6-2 = 4 choices for the second slot, and so on until we get down to 6-5 = 1 choice for the fifth slot

We could write it out like this

Multiply those values out: 5*4*3*2*1*3 = 360

There are 360 different even numbers possible.

Answer:

Obtuse triangle

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. There are different types of triangles such as right angled, acute, obtuse and isosceles triangle.

In right angle triangle, one angle is 90°. The square of the longest side (hypotenuse) is equal to the sum of the square of the two sides.

An acute triangle is a triangle with acute angles (less than 90°). The square of the longest side is less than the sum of the square of the two sides.

An obtuse triangle is a triangle with one obtuse angle (greater than 90°) and two acute angles (less than 90°). The square of the longest side is larger than the sum of the square of the two sides.

An isosceles triangle is a triangle with two equal sides.

Given a triangle whose side lengths are 8, 16, and 18, the longest side is 18.

Since no two sides are the same hence it is not an isosceles triangle.

Also, 18² > 16² + 8²; therefore this is an obtuse triangle

Answer:

the slope is 5/-3 , the way i did this is in the picture

Answer:

y = x-4

Step-by-step explanation:

The standard form is;

y = mx + b

where m is the slope and b is the y-intercept

we have the two points as (0,-4) and (5,1)

so we find the slope using the slope formula;

m = (y2-y1)/(x2-x1)

m = (1 + 4)/(5-0) = 5/5 = 1

The y-intercept value is the value of y when x = 0

We already have a point (0,-4) and the equation would be:

y = 1(x) + (-4)

y = x-4
