Question

If F = 6 & dx = - 20 then find fdx​

Answer 1

SOLUTION

GIVEN

$\displaystyle \sf{F = 6 \: , \: \sum dx = - 20}$

TO DETERMINE

$\displaystyle \sf{ \sum f \: dx }$

EVALUATION

Here it is given that

$\displaystyle \sf{F = 6 \: , \: \sum dx = - 20}$

Now

$\displaystyle \sf{F = \frac{\sum f \: dx }{\sum dx } }$

$\displaystyle \sf{ \implies \: 6 = \frac{\sum f \: dx }{ - 20 } }$

$\displaystyle \sf{ \implies \: \sum f \: dx = - 20 \times 6 }$

$\displaystyle \sf{ \implies \: \sum f \: dx = -1 20 }$

FINAL ANSWER

$\displaystyle \sf{ \: \sum f \: dx = -1 20 }$
