Answer:

Step-by-step explanation:

A function has at most one y value for every x value. This means that for every vertical line, there can be at most one intersection.

This example clearly doesn't satisfy this requirement.

The perimeter of the triangle shown is 412 meters. Find the length of each side.

Fudgin [204]

Answer:

x meters= 35

5x meters= 175

6x - 8 = 202

Step-by-step explanation:

x + 5x + (6x - 8)= 412

12x - 8= 412

12x = 412 + 8

12x = 420

x= 35

5x = 35× 5

= 175

6x - 8= 6(35) - 8

= 210 - 8

= 202

Given:

Which Cylinders have the same volume as the cylinder below? Cheok all that apply, height- 20m and base- 32m:

Answer choices:

picture 1: 40m and 16

picture 2: 5m and 64

picture 3: 40m and 8

picture 4: 32m and 20

picture 5: 10m and 128

Formula for Cylinders:

V=Bh or V=πr²h

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

Diameter = Half of Radius {Divide by 2}

Original Cylinder:

20m and 32m

20/2 = 10

V=πr2h=π·102·32≈10053.09649

V ≈ 10053.1

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Picture 1: 40m and 16

40/2 = 20

V=πr2h=π·202·16≈20106.19298

V ≈20106.19

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

picture 2: 5m and 64

5/2 = 2.5

V=πr2h=π·2.52·64≈1256.63706

V ≈1256.64

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

picture 3: 40m and 8

40/2 = 20

V=πr2h=π·202·8≈10053.09649

V≈10053.1

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

picture 4: 32m and 20

32/2 = 16

V=πr2h=π·162·20≈16084.95439

V≈16084.95

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

picture 5: 10m and 128

10/2 = 5

V=πr2h=π·52·128≈10053.09649

V≈10053.1

How can x2 = x2 + 2x + 9 be set up as a system of equations? Y = x2 ? 9 y = x2 + 2x + 9 y = x2 y = x2 + 2x + 9 y = x2 + 2x y = x

weeeeeb [17]

Answer: B

Step-by-step explanation:

Set the left side of the equation equal to y AND set the right side of the equation equal to y to create two separate equations:

y = x²

y = x² + 2x + 9

The expression x²-14x+31=63 is a quadratic equation. To solve it, you must order it:

x²-14x+31-63=0

x²-14x-32=0

Then, you must apply the quadratic formula, which is shown below:

x=(-b±√(b^2-4ac))/2a

So you have the values of a,b and c:

a=1

b=-14

c=-32

When you substitute those values in the quadratic formula, you obtain:

x=(-(-14)±√((-14)^2-4(1)(-32))/2(1)

x1=-2

x2=16

So, the correct option is the third one: x=-2 or x=16
