Answer: 2(0) + 8 does not equal 12, not a solution.

2(2) +8 = 12 yes it is a solution

2(-3) + 8 does not equal 12, not a solution

2(5) + 8 does not equal 12, not a solution.

Step-by-step explanation:

Looks like you need to plug in each y value given and multiplied by 2 and add 8

2(0) + 8 does not equal 12, not a solution.

2(2) +8 = 12 yes it is a solution

2(-3) + 8 does not equal 12, not a solution

2(5) + 8 does not equal 12, not a solution.

ANSWER

\sqrt{13}  = 3.606

to the nearest thousandth.

EXPLANATION

The given irrational number is

\sqrt{13}

We use the calculator to evaluate this to obtain,

\sqrt{13}  = 3.605551...

To round to the nearest thousandth means we are rounding to 3 decimal places.

The third decimal place is 5.

The next number is 5 so we round up.

\sqrt{13}  = 3.606

PLEASE HELP ASAP!!
V125BC [204]

Answer:

D

Step-by-step explanation:

Calculating the volumes of both solids

Volume of a cube = s³ ( where s is the side length )

here s = 10, hence

V = 10³ = 10 × 10 × 10 = 1000 in³

Volume of a cylinder = area of base × height

Area of circular base = πr²

here r = 10 and h = 12, hence

V = π × 10² × 12 = 1200π ≈ 3769 .9 in³

The volume of the cylinder is greater than the volume of the cube → D
