Make t the subject of k = \(m \sqrt \frac{t-p}{r}\)

A.

\(\frac{k^2r + p}{m^2}\)

B.

\(\frac{k^2r + pm^2}{m^2}\)

C.

\(\frac{k^2r - p}{m^2}\)

D.

\(\frac{k^2r + p^2}{m^2}\)

Correct answer is B

square both sides to remove the square root

k\(^2\) = m\(^2\) \(\frac{t-p}{r}\)

\(\frac{k^2r}{m^2}\) = t - p

t = \(\frac{k^2r}{m^2}\) + p

t = \(\frac{k^2r + pm^2}{m^2}\)

Find the value of x such that \(\frac{1}{x}\) +\(\frac{4}{3x}\) - \(\frac{5}{6x}\) + 1 = 0

A.

\(\frac{1}{6}\)

B.

\(\frac{1}{4}\)

C.

\(\frac{-3}{2}\)

D.

\(\frac{-7}{6}\)

Correct answer is C

\(\frac{1}{x}\) +\(\frac{4}{3x}\) - \(\frac{5}{6x}\) + 1 = 0
using 6x as lcm

→ \(\frac{6+8-5+6x}{6x}\) 

→ \(\frac{9+6x}{6x}\) = 0

9+6x = 0

6x = -9

x = \(\frac{-9}{6}\)  or \(\frac{-3}{2}\)
