Make x the subject of the formula for Q20.

saul85 [17]

Answer:

$x = \sqrt{m(\frac{a}{b})^{2} +n }$

Step-by-step explanation:

$a\sqrt{(\frac{x^{2} - n }{m}) } = \frac{a^{2} }{b}$

$\sqrt{\frac{x^{2} - n }{m} } = \frac{a}{b}$ [Divide both sides by $a$ ]

$\frac{x^{2} - n}{m} = (\frac{a}{b} )^{2}$ [Square both sides]

$x^{2} -n = m(\frac{a}{b} )^{2}$ [Multiply both sides by m]

$x^{2} =m(\frac{a}{b} )^{2} + n$ [Bring n to the right]

$x = \sqrt{m(\frac{a}{b})^{2} +n }$ [Square root both sides]

In the right triangle shown, AC = BCAC=BCA, C, equals, B, C and AB = 6AB=6A, B, equals, 6.

alexandr402 [8]

Answer:

$|AC|=|BC|=3\sqrt{2}$

Step-by-step explanation:

In a right triangle, the hypotenuse is always the longest side. Since AC = BC, AB is the Hypotenuse.

Using Pythagoras theorem

$|AB|=6,|AC|=|BC|\\|AB|^2=|AC|^2+|BC|^2\\6^2=2|AC|^2\\36=2|AC|^2\\18=|AC|^2\\|AC|=\sqrt{18}=3\sqrt{2} \\Therefore, |AC|=|BC|=3\sqrt{2}$
