+152 \(a=\frac{v}{t}\) solve for t
\(A=\pi r^2\) solve for r
\(P=I^2R\) solve for I
+37163 a = v/t Multiply both sides of the equation by 't
at = v Divide both sides by 'a'
t = v/a
A=pi r^2 Divide both sides by pi
A/pi = r^2 Sqrt both sides
sqrt(A/pi) = r Do you see how it is done? Can you do the third one?
+37163 I think you are correct....can honestly say I have not found ONE SINGLE thing in the 'update' that was a good change.
+9479 Lol how about the hearts for points EP?
You gotta at least like them a little x)
+37163 Nope. Posted earlier that I thought the hearts were cheesy and the symbol should be something math-related like # or the pi symbol ! Just not feelin' the heart thingie ....
+9479 All "solve for" means is get the variable by itself on one side of the equal sign.
\(a=\frac{v}{t}\)
Multiply both sides of the equation by t.
\(ta=v\)
Divide both sides of the equation by a.
\(t=\frac{v}{a}\)
Hey! time = velocity / acceleration
\(A = \pi r^2\)
Divide both sides of the equation by pi.
\(\frac{A}{\pi} = r^2\)
Take the + square root of both sides.
\(\sqrt{\frac{A}{\pi}} = r\)
radius = the square root of (area / pi)
The third one is exactly the same as the second one just with different letters.
