What's the difference between a independent variable and dependent variable

Travka [436]

Answer:

The dependent variable depends on the independent variable.

Step-by-step explanation:

The variable whose values are deliberately changed by the researcher in order to obtain the desired outcome is called independent variable...
The values of the independent variable can be changed as per requirement, by the researcher...
Manipulation can be done in the values of independent variable, but the researcher observes the value of a dependent variable during an experiment.
An independent variable is a presumed cause whereas dependent variable is a measured effect.
In a simple linear regression, ‘y’ denotes dependent variable while ‘x’ denotes independent variable, which means y depends on x

Find the area of a circle with a circumference of 2 pie

shusha [124]

We know that formula for circumference is 2πr

Since we have circumference of 2π, that would means 2π = 2πr.

We need to solve for r. We can divide both sides by 2π:

2π / 2π = 2πr / 2π

1 = r

So radius is 1.

Now the formula for area of circle is πr². So plug in r=1 and that would be

π(1)²

π

So area of circle is π.

Hope this helps.

I need help!! please, you don’t even have to do it all just explain to me how to do the first one I’ll catch on

Hi there!

What we need to know:

The three main trigonometric ratios are sine, cosine and tangent:

$\displaystyle sin\theta=\frac{opposite}{hypotenuse}$ $\displaystyle cos\theta=\frac{adjacent}{hypotenuse}$ $\displaystyle tan\theta=\frac{opposite}{adjacent}$

"Opposite" refers to the side opposite the angle that is not the hypotenuse.

"Hypotenuse" refers to the side opposite the right angle of a right triangle.

"Adjacent" refers to the side next to the angle that is not the hypotenuse.

"θ" is read as "theta". It just represents the angle.

Keep in mind that these three ratios only apply to right triangles.

You can use the mnemonic "soh-cah-toa" to help you remember these ratios.

First question

For the first question, we're given the angle with a measure of 56 degrees and the length of the hypotenuse. We must calculate a, which represents the side adjacent to the given angle.

Given the hypotenuse and the adjacent side, we know that we must use the cosine ratio:

$\displaystyle cos\theta=\frac{adjacent}{hypotenuse}$

Plug in the given information:

$\displaystyle cos56=\frac{a}{13}$
