Georgia [21]

Answer:

D) x = √5

Step-by-step explanation:

\sqrt{x^{2}+4 }-1 = 2

\sqrt{x^{2}+4 } = 3

x^{2}+4 = 3^{2}

x^{2}+4 = 9

x^{2} = 9 -4

What is the approximate volume of one refraction cup? What’s its formula ?
Marizza181 [45]

Answer:

Volume = 0.1696 L

The formula is Area of base of refraction cup × Depth of the refraction cup

Step-by-step explanation:

The dimensions of a refraction cup are;

Diameter = 120 mm

Depth = 30 mm

Therefore, volume of the refraction cup = Area of base × Depth

Volume of the refraction cup = (π×120²/4)/2 × 30 = 169646.003 mm³

1 L = 1000000 mm³

Therefore, 169646.003 mm³ = 169646.003/1000000 m³ = 0.1696 L

The formula is Area of base of refraction cup × Depth of the refraction cup.
