We are asked to solve the formula [tex]D=\frac{1}{2}fk[/tex] for [tex]f[/tex]. Starting off, we can divide both sides by [tex]k[/tex], so we are left with only the variable [tex]f[/tex] on the right-hand side. Next, we need to multiply the reciprocoal of [tex]\frac{1}{2}[/tex], which is [tex]2[/tex] to both sides. This gives us [tex]2*\frac{D}{k}=f[/tex], which, when simplified, gives us [tex]\boxed{f=\frac{2D}{k}}[/tex]. Hope this helped and have a phenomenal day!
