Answer:

\theta=\frac{2A}{r^{2} }

Step-by-step explanation:

The given formula is

A=\frac{\theta r^{2} }{2}

We have to solve the formula for \theta. To do that, we first need to past the divisor 2 to the other side, as follows

2A=\theta r^{2}

Then, we have to move the squared radius to the other side with the opposite operation, that is, dividing

\frac{2A}{r^{2} } =\theta \\\theta=\frac{2A}{r^{2} }

Threfore, the given expression solved for \theta is

\theta=\frac{2A}{r^{2} }

Answer:

\theta=\frac{2A}{r^2}

Step-by-step explanation:

Given : The formula A=\frac{\theta r^2}{2}

We have to rearrange the given formula for \theta

Consider the given formula A=\frac{\theta r^2}{2}

Multiply both side by 2, we have,

2A={\theta r^2

Divide both side by r^2 , we have,

\frac{2A}{r^2}= \frac{\theta r^2}{r^2}

Simplify, we get,

\frac{2A}{r^2}=\theta

Thus, \theta=\frac{2A}{r^2}

Anyone have these or know them???

The answer would be y = 6x.

The reason for this is that when we add a number in front of x, it makes it go up vertically by the factor of that number. So if we are to stretch the graph vertically, the only way we can do it is by making 6 the coefficient.
