Make x the subject of the formula (mx^2=f)

wolverine [178]

Answer:

x = ± $\sqrt{\frac{f}{m} }$

Step-by-step explanation:

Given

mx² = f ( isolate x² by dividing both sides by m )

x² = $\frac{f}{m}$ ( take the square root of both sides )

x = ± $\sqrt{\frac{f}{m} }$

What is the value of −9/4 + |−8/5| − 2 1/2 ?

mariarad [96]

Answer:

$-2\frac{3}{4}$

Step-by-step explanation:

Given: −9/4 + |−8/5| − 2 1/2

Rewriting: $-\frac{9}{4} + |-\frac{8}{5} |-2\frac{1}{2}$

Absolute value: $-\frac{9}{4} + \frac{8}{5} -2\frac{1}{2}$

Improper fractions: $-\frac{9}{4} + \frac{8}{5} -\frac{5}{2}$

Common denominators: $-\frac{45}{20} + \frac{40}{20} -\frac{50}{20}$

Solving from left to right: $-\frac{5}{20} -\frac{50}{20}$

Solving from left to right part two: $-\frac{55}{20}$

Simplifying: $-\frac{55}{20}= -\frac{11}{4} =-2\frac{3}{4}$

Answer: $-2\frac{3}{4}$

Hope this is correct and helps, have a nice day! :D
