Answer:

Step-by-step explanation:

V, r, h are the volume, radius, and height, respectively.

V = πr²h = 9πr²

The only error in your previous answers was that you forgot the π.

if r = 1, V = 9π1² = 9π ≅ 28 in³

if r = 2, V = 9π2² = 36π ≅ 113 in³

if r = 3, V = 9π3² = 81π ≅ 254 in³

What are the solution(s) to the quadratic equation 9x2 = 4?
Kaylis [27]

Answer:

Option B.

Step-by-step explanation:

The given quadratic equation is

9x^2=4

We need to find the solution of given quadratic equation.

Divide both sides by 9.

\frac{9x^2}{9}=\frac{4}{9}

x^2=\frac{4}{9}

Taking square root on both sides.

x=\pm\sqrt{\frac{4}{9}}

x=\pm\frac{2}{3}

The solution of given equation are x=\frac{2}{3} and x=-\frac{2}{3}.

Therefore, the correct option is B.

PLEASE HELP!! WILL MARK BRAINLIST ​
gayaneshka [121]

Answer:

3/50 7/50 40/50

Step-by-step explanation:

Ok. I'm not exactly a math wiz but I think you may be overthinking this. Experimental probability should be the probability from the experiment right. It's in the name. In chemistry if it's a well established value it's called a theoretical value or probability. So the answer should just be the probability from the said experiment. No other funky math terms are given here which clues me to the idea that it might just be this simple.

Describe how to transform the quantity of the sixth root of x to the fifth power, to the seventh power into an expression with a
bekas [8.4K]
<span>The power of the root of the power of a variable can be written as a rational power by creating a rational exponent that is the product of the powers divided by the root. The rational exponent should be reduced to lowest terms. For example, the seventh power of the sixth root of the fifth power of x will be x^(7*5/6) = x^(35/6).
hope it helps
