half the sum of 8 and r​

Answer:

if what you're asking if 0 belongs to anyone of the sets then zero belongs to whole numbers.

whole numbers is 0,1,2,3,4 etc

Natural numbers are 1,2,3,4 etc

integers are -3,-2,-1,0,1,2,3 etc

rational numbers are like fractions etc

irrational numbers are when you don't necessarily get a exact or whole numbers for example like π/pie

Answer:

(23/27, 11/9)

Step-by-step explanation:

Given the simultaneous equation;

-6x+5y=1..... 1

6x+4y=10.... 2

Add both equations

5y + 4y = 1+10

9y = 11

y = 11/9

Substitute y = 11/9 into 1;

From 1;

-6x+5y=1.

-6x + 5(11/9) = 1

-6x + 55/9 = 1

-6x = 1- 55/9

-6x = (9-55)/9

-6x = -46/9

x = -46/-54

x = 23/27

The solution to the system of equation is (23/27, 11/9)

Answer:

V = 6x^3 - 9x^2 - 6x (which matches the third answer choice)

Step-by-step explanation:

The volume of a rectangular prism of length L, depth W and height H is

V = L * W * H.

Thus,

in this case,

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

The order in which we multiply these quantities together is immaterial.

Working from left to right, we get:

V = (2x^2 - 3x - 2)(3x), and then:

V = 6x^3 - 9x^2 - 6x (which matches the third answer choice)

Answer:

846.06 units

Step-by-step explanation:

The amount of profit, y, made by the  company, is related to the selling price of each widget, x, by the given  equation as follows :

[tex]y = -4x^2 + 183x- 1247[/tex] ...(1)

We need to find out the maximum amount of profit  the company can make.

For maximum profit put dy/dx = 0

So,

[tex]\dfrac{d}{dx}(-4x^2 + 183x- 1247)=0\\\\-8x+183=0\\\\x=\dfrac{183}{8}\\\\x=22.87[/tex]

Put x = 22.87 in equation (1). So,

[tex]y = -4(22.87)^2 + 183(22.87)- 1247\\\\=846.06[/tex]

So, the maximum profit is 846.06 units.

Answer:

Step-by-step explanation:

Example 1:

Evaluate the following expression:

4 + (3x +y)

When x = 2 and y = 9

3 x 2 is 6 after that you just add 6+9+4 which is 19

Example 2:

Evaluate the expression when x=8 and y=9

x(y - 9)^3 + 2

=8(9-9)^3+2

=8(0)^3+2

=8(0)+2

=0+2

=0

the distance between Dan and jeff is 26 feet

Answer:

can i see the rest of it

Step-by-step explanation:

Given:

The three equations for the three numbers are

[tex]a=x^2-y^2[/tex]

[tex]b=2xy[/tex]

[tex]c=x^2+y^2[/tex]

To find:

The Pythagorean triple generated by using 4 for x and 1 for y.

Solution:

Substituting x=4 and and y=1 in the given equations, we get

[tex]a=4^2-1^2[/tex]

[tex]a=16-1[/tex]

[tex]a=15[/tex]

In the same way find b and c.

[tex]b=2(4)(1)[/tex]

[tex]b=8[/tex]

The third number is

[tex]c=4^2+1^2[/tex]

[tex]c=16+1[/tex]

[tex]c=17[/tex]

The required Pythagorean triple is 8, 15, and 17.

Therefore, the correct option is C.

Answer:

Some examples

Step-by-step explanation:

1.The vertices of triangle ABC are A(2,-3), B(-3,-5), and C(4,1). For each translation, give the vertices of triangle A'B'C'. When the transformation (-2,3). When the T (-4,-1) and T

C

2.Triangle ABC has vertices A(-3,0) B(0,6) C(4,6). Find the equations of the three medians of triangle ABC

Triangle ABC has vertices A(-3,0) B(0,6) C(4,6). Find the equations of the three altitudes of the same triangle

Triangle ABC has vertices A(-3,0) B(0,6) C(4,6). Find the equations of the three perpendicular bisectors of the same triangle.

A(−3, 0), B(0, 6), and C(4, 6)

using the midpoint formula:  we can find all of their midpoint which is necessary to complete question 1 and 2

Mid AB=(-1.5, 3), Mid BC=(2, 6), Mid AC=(0.5,3)

Next, we have to find the slope of from the vertex and the midpoint of each side. We use the slope formula: .

You would get -6, 6/5, and 6/11.

Next you substitute in the coordinates for the equation of each for example: y=-6x, you switch in the set of cords AB which is (-1.5, 3). 3=-6(-1.5)+z and find that z=6, so the equation is y=-6x+6. As for the rest, repeat the same process until you find all 3 cords. You should get an answer of

For question 2,

The line has to be perpendicular bisector to the midpoint, signifying that it has to split 2 angles into congruent angles and a side into half. In order to do that we need to first find the opposite reciprocal of each side's slope. Which means we need to once again use the slope formula and get the opposite reciprocal by . For all the opposite reciprocal slopes you get will be incorporated into the final formulas. That gives us the slopes of -1/2, 0 and -7/6.

I hope this helps! :)

Answer:

A 61

Step-by-step explanation:

Cos A = 0.4848

A = cos ^-1(0.4848)

A = 61

Answer:

Angle A is 52 degrees           Angle B is 78 degrees

Step-by-step explanation:

The angles all have to add up to 180.

2x + 3x + 50 = 180

5x + 50 = 180

Subtract 50 from both sides

5x = 130

Divide each side by 5

x = 26

Solve

A) 2 * 26 = 52

B) 3 * 26 = 78

--------Check--------

52 + 78 +50 = 180

180 = 180
