OKAY, guys give me a really brilliant explanation on how 2+2=4. It should be 22. It doesn't make sense.

answer:

it's a function

step-by-step explanation:

according to g00gle- in mathematics, a function is a binary relation between two sets that associates to each element of the first set exactly one element of the second set. typical examples are functions from integers to integers, or from real numbers to real numbers.

but the simple definition is that a function is when the x value isn't being repeated. and since in your case it isn't, the table is a function

another way to solve-

for this, we will put the pairs into a graph then perform the line test-

as you can see each point has its own individual line, therefore, meaning it passed the vertical line test

good luck :)

i hope this helps

brainliest would be highly appreciated

have a nice day!

Answer:

A) 127.16π m³

Step-by-step explanation:

Volume of a cylinder:

V = πr²h

Given:

r = 3.4

h = 11

Work:

V = πr²h

V = π(3.4²)(11)

V = π(11.56)(11)

V = 127.16π

Answer:

hey bestie, its 127.16

Step-by-step explanation:

3.4 squared is 11.56

and 11.56 times 11 is 127.16

Answer:

The angle is 90 degrees

Step-by-step explanation:

Required

Angle subtended by the diameter

The theorem to solve this is:

The angle subtended by an arc is twice the angle it subtends.

The diameter forms [tex]180^\circ[/tex] on the circle, so we have:

[tex]2*\theta = 180^\circ[/tex]

Where [tex]\theta[/tex] is the angle subtended

Solve for [tex]\thets[/tex][tex]\theta[/tex]

[tex]\theta = \frac{180^\circ}{2}[/tex]

[tex]\theta = 90^\circ[/tex]

Answer:

A. 12 ≥ w ≥ 33

Step-by-step explanation:

So as wide as 33, means that it could be less than or equal to 33. And as narrow as 12 means greater than or equal to 12, so put that together and we have our answer

if this is wrong let me know so I can fix it

hope this helps:)

Answer:

  a = 108°

  b = 24°

Step-by-step explanation:

a) The pentagon will have interior angles of 540°/5 = 108°.

 Angle a = 108°

__

b) The reflex angle at a vertex of the pentagon is 360° -108° = 252°. At the obtuse angle of the unshaded triangle, 120° of that amount is take up by two internal angles of the equilateral triangles. Those are 60° each. So, the obtuse angle in the unshaded triangle is ...

  252° -120° = 132°

That triangle is isosceles, so the angle at b is ...

  2b° +132° = 180°

  b = (180 -132)/2 = 48/2 = 24

  Angle b = 24°

Answer:

a = 108 °

b = 24°

Step-by-step explanation:

Answer:

V = 567 ft³

Step-by-step explanation:

V = Bh

[note: a capital 'B' represents the area of the base]

The right triangle is the triangular prism's base.

Because the triangle's height (9 ft) and it's base are the same value (9 ft), we can solve to find the area.

Area of triangular base:

 A = [tex]\frac{bh}{2}[/tex]

 A = [tex]\frac{1}{2}[/tex] (9 ⋅ 9)

 A = [tex]\frac{1}{2}[/tex] (81)

 A = 40.5

We have 'B' for the triangular prism's formula, so next we need 'h'. 14 ft is provided as the prism's height, so we just need to multiply 40.5 and 14 for our answer.

Volume of triangular prism:

 V = Bh

 V = (40.5)(14)

 V = 567 ft³

Step-by-step explanation:

173-10+3(25+1)=241

238-7=231

118-7=111

118-9=109

Answer: A. -6=n

Step-by-step explanation:

3(x - 2) =7x+n

3x-6=7x+n

-6=4x+n

-6=4(0)+n

-6=n

Let's solve your system by elimination.

8x+y=−16;3x−y=5

8x+y=−16

3x−y=5

Add these equations to eliminate y:

11x=−11

Then solve: 11x=−11 for x:

11x=−11

11x

11

=

−11

11

(Divide both sides by 11)

x=−1

Now that we've found x let's plug it back in to solve for y.

Write down an original equation:

8x+y=−16

Substitute: −1 for x in 8x+y=−16:

(8)(−1)+y=−16

y−8=−16(Simplify both sides of the equation)

y−8+8=−16+8(Add 8 to both sides)

y=−8

Answer:

x=−1 and y=−8

Answer:Multiply each equation by a suitable number so that the two equations have the same leading coefficient.

Subtract the second equation from the first.

Solve this new equation for y.

Substitute y = 2 into either Equation 1 or Equation 2 above and solve for x.

Step-by-step explanation:

[tex](4h^{2} -h+5) - (8h-3h+12)\\4h^{2} -h+5 - 8h+3h-12\\4h^{2}-9h+3h-7\\4h^{2}-6h-7\\[/tex]

The root is the x intercepts or the zeros of the problem

If I were to graph

(x-5)(x+4)=0

We need a number for x which makes this equation 0

The numbers are 5 or -4

These are the x intercepts of the parabola or roots

Answer:

The roots of a function are the x-intercepts. By definition, the y-coordinate of points lying on the x-axis is zero. Therefore, to find the roots of a quadratic function, we set f (x) = 0, and solve the equation, ax2 + bx + c = 0.

Percentage of Karaks= 40%

Step-by-step explanation:

Giving the following information:

The total number of Karaks involved in flower cultivation is 1000.

Total population= 2,500

To calculate the percentage of Karaks, we need to use the following formula:

Percentage of Karaks= (1,000 / 2,500)*100

Percentage of Karaks= 40%

Step-by-step explanation:

Answer:

Direction of travel.

Step-by-step explanation:

Given that two vehicles traveled 200 km in 3 hours ;

Distance apart after 3 hours = 400 km

A logical solution to this final distance between the two cars can be explained by their direction of travel.

Since the Cars both covered the same distance over the same period of time, the both cars must have started from a common point and traveled in opposite direction.

Meaning ;

Car 1 traveled 200 km in a certain direction

Car 2 traveled 200km in the opposite direction

Hence, distance between the cars will be :

Distance covered by car 1 + distance covered by car 2

200km + 200km = 400km
