Select the correct answer.
which function's domain consists of all real numbers except -2?​

Answer:

14

Step-by-step explanation:

Make the two function equal to eachother and then, bring -8 to the right which will be added with 20 to get 28. Now you left with 2x on the left side, divide both sides by 2 to solve for (x). Thus x= 14.

Step-by-step explanation:

just subtract starting with the numbers after the decimal place

Answer and Step-by-step explanation:

To get this answer you need to understand what a function is, a function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output. If this is false, this is NOT a function. So, knowing that, the correct answers are, All functions have a dependent variable, All functions have an independent variable, and A horizontal line is an example of a functional relationship. So this 1st, 2nd, and 5th options.

Answer:

A I did the same quiz it’s A

Step-by-step explanation:

The correct option is "option A".

A function is graphed in the given figure.

We have to tell that which option is correct related to the graph.

What is a function ?

The function is the description of how the inputs relate to the output.  Each input has only one output.

According to the figure / graph ;

When x < 3

Then , y = [tex]x^{2}[/tex] + 6

Also , at , x = 3

We get an open interval.

So, we can say that ;

y = [tex]x^{2}[/tex] + 6 is valid for x < 3 not at x =3

Also , y = -x + 6 is valid for x ≥ 3 , here we get a close interval.

Thus , the correct option will be "option A" i.e.,

y = { x² + 6 , x < 3

and

y = { -x + 6 , x ≥ 3

Answer:

1920 rings

Step-by-step explanation:

We need to simply find the volume of the package and the volume of the cube and then divide the volume of the package by the volume of the cube.

The package is a rectangular prism. The volume of a rectangular prism is:

V = L * W * H

where L = length

W = width

H = height

The volume of the package is:

16 * 10 * 12 = 1920 [tex]in^3[/tex]

The volume of a cube is:

V = L^3

where L = length of side

The volume of the cube is:

V= 1^3 = 1 [tex]in^3[/tex]

The number of rings the jewelry store received is:

1920 / 1 = 1920 rings

Answer:

346 cm²

Step-by-step explanation:

Area of square:

Area = [tex]Length*Length[/tex]

A = 20*20

A = 400 cm²

Area of rectangle:

Length = 3 cm

Width = 20-2 = 18 cm

Now, The Area:

Area = [tex]Length * Width[/tex]

Area = 3 * 18

Area = 54 cm²

Now, The difference in their areas:

=> 400-54

=> 346 cm²

Answer:

Step-by-step explanation:

An isosceles triangle has two equal sides and two equal base angles.

Given that : AK = KC and MN∥ AC

ΔMNB is similar to ΔACB (congruence property)

ΔANB = ΔANC (SAS congruence property)

ΔCMB = ΔCMA (SAS congruence property)

[tex]\frac{AB}{BN}[/tex] = [tex]\frac{AC}{CN}[/tex] (Angle bisector theorem)

So that:

<BAC = <ACB (base angle property of an isosceles triangle)

/AB/ = /BC/ (side property of an isosceles triangle)

Therefore, ΔABC is an isosceles triangle.

Answer:

The surface area of the cylinder is 276.32m²

Step-by-step explanation:

To solve this problem we have to calculate the circle area and the lateral area

To calculate the area of ​​the circle we use the following formula

a = area

r = radius = 2m

π = 3.14

a = π * r²

we replace with the known values

a = 3.14 * (2m)²

a = 3.14 * 4m²

a = 12.56m²

The area of the circle is 12.56m²

To calculate the lateral area of ​​the cylinder we use the following formula

a = area  =

h = heighti = 20m

r = radius = 2m

π = 3.14

a = 2 * π * r * h

we replace with the known values

a = 2 * 3.14 * 2m * 20m

a = 6.28 * 40m²

a = 251.2m²

The lateral area of ​​the cylinder is 251.2m²

Now we add the lateral area of ​​the cylinder with 2 times the area of ​​the circle and obtain the area of ​​the cylinder

251.2m²  + (2 * 12.56m²) = 276.32m²

The surface area of the cylinder is 276.32m²

The experimental probability is [tex]\frac{10}{15+10+40+20+40}=8\%,[/tex] while the theoretical probability, assuming random selection, is [tex]\frac{1}{5}=20\%,[/tex] so the theoretical probability is greater than the experimental probability.

Answer for 1. 72

Answer for 2.536

Answer for 3.195

Answer:

In standard form: x - 2y = -10

In slope intercept form: y = (1/2)x + 5

Step-by-step explanation:

y = total cost

y = flat cost + mileage cost

The flat cost is $5, so you get

y = 5 + mileage cost

The mileage cost depends on the number of miles, x.

1 mile costs $0.50

2 miles cost $0.50 * 2

3 miles cost $0.50 * 3

x miles cost $0.50 * x, or simply 0.5x

Now we add the mileage cost to our expression.

y = 5 + 0.5x

y = 0.5x + 5

In standard form:

0.5x - y = -5

x - 2y = -10

In slope intercept form:

y = (1/2)x + 5

Answer:

Step-by-step explanation:

area of triangle = 1/2 * base * height = 1/2 * 9 = 9/2

area  of semicircle = 22/7 * {3 root 2 / 2}^2 = 22/7 *18 / 4 = 22/7 *9/2 = 198/14=99/7

area of figure =  99/7 + 9 /2 =18.6mm2

mark me as the brainliest

Answer:

area of figure= area of semi circle + area of triangle

area of semi circle= 1/2πr²

1/2×3.14×2.12×2.12

1/2×14.11

= 7.06

area of triangle = 1/2×base×height

but I am going to use the Pythagoras theorem to find the its height

= hypotenus² = base²+height²

3²=2.12²+h²

9=4.5+h²

9-4.5=h²

√4.5=√h²

h= 2.12

so area of triangle= 1/2×4.24×2.12

=4.5

area of figure = 70.6+4.5

= 75.1mm²

Answer:

Option (1). (6, 0)

Step-by-step explanation:

The given question is incomplete; here is the complete question.

Which is the ordered pair for the point on the x-axis that is on the line parallel to the given line and through the given point (–6, 10)?

(6, 0)

(0, 6)

(−5, 0)

(0, −5)

Line in orange color is passing through two points (-8, 6) and (4, -4)

Slope of this line = [tex]\frac{\triangle y}{\triangle x}[/tex]

                            = [tex]\frac{6+4}{-8-4}[/tex]

                            = [tex]-\frac{10}{12}[/tex]

                            = [tex]-\frac{5}{6}[/tex]

Other line parallel to this line will have the same slope 'm' = [tex]-\frac{5}{6}[/tex]

Parallel line passes through a point (-6, 10).

Let the other point through which the parallel line passes is (a, b)

Now, [tex]-\frac{5}{6}[/tex] = [tex]\frac{10-b}{-6-a}[/tex]

-5(-a - 6) = 6(10 - b)

5a + 30 = 60 - 6b

5a = -6b + 60 - 30

5a = -6b + 30

a = [tex]-\frac{6}{5}b+6[/tex]

By satisfying with all the options we find only (6, 0) satisfy this equation.

6 = [tex]-\frac{6}{5}(0)+6[/tex]

6 = 6

Therefore, (6, 0) is the other point lying on the parallel line.

Option (1) will be the answer.
