Answer: V≈ 452.39

Step-by-step explanation:

First you have to plug in the values into the equation $\pi x^{2}$ x h. That would mean, pi 6^2x4. Do the math and you get around 452

Answer:

$144\pi$

Step-by-step explanation:

Formula for the volume of a cylinder is the Base Area x Height

$V= \pi r^{2} * h$

Plug in the values:

$V = \pi(6)^2 * 4$

$V = 36\pi *4 = 144\pi$

Solve this equation using all three methods 4x^ = 9

Bumek [7]

Answer:

$x=-\frac{3}{2}, x=\frac{3}{2}$

Step-by-step explanation:

(1) To solve by factoring,

Given equation: $4 x^{2}=9$

Subtract 9 from both sides of the equation.

$\begin{aligned}&4 x^{2}-9=9-9\\&4 x^{2}-9=0\\&(2 x)^{2}-3^{2}=0\\&(2 x-3)(2 x+3)=0\end{aligned}$

Using zero factor principle, $2 x-3=0,2 x+3=0$

The solutions are $x=-\frac{3}{2}, x=\frac{3}{2}$ .

(2) To solve by complete the square ,

Given $4 x^{2}=9$

Divide both sides of the equation by 4.

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

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

Square root on both sides.

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

$x=-\frac{3}{2}, x=\frac{3}{2}$

(3) To solve by quadratic formula,

$4 x^{2}-9=0$

Here, a = 4, b = 0, c = –9

Quadratic formula, $x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}$

$x=\frac{-0 \pm \sqrt{0^{2}-4 \times 4 \times(-9)}}{2 \times 4}$

$\begin{aligned}&\Rightarrow x=\frac{\pm \sqrt{144}}{8}\\&\Rightarrow x=\pm \frac{3}{2}\\&\Rightarrow x=\frac{3}{2}, x=-\frac{3}{2}\end{aligned}$

The relationship between number of animals owned and the number of vet bills is an example of what type of correlation

irakobra [83]

Answer:

The relationship between number of animals owned and the number of vet bills is an example positive correlation.

Step-by-step explanation:

Correlation:

Correlation is a technique that help us to find or define a relationship between two variables.
It is a measure of linear relationship between two quantities.
A positive correlation means that an increase in one quantity leads to an increase in another quantity
A negative correlation means with increase in one quantity the other quantity decreases.
+1 tells about a a perfect positive linear relationship and −1 indicates a perfect negative linear relationship.

Now, as the number of animals increase the number of vet bills will increase. Thus, it could be said that increase in one variable leads to increase in another variable.

Thus, the given relationship is an example of positive relationship or a positive correlation.
