The correct answer is B trustttttttt
Answer:
see explanation
Step-by-step explanation:
Assuming you require the derivative of f(x) from first principles, then
f' (x) =
![\frac{f(x+h)-f(x)}{h}](https://tex.z-dn.net/?f=%5Cfrac%7Bf%28x%2Bh%29-f%28x%29%7D%7Bh%7D)
=
![\frac{\frac{1}{(x+h)}-\frac{1}{x} }{h}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cfrac%7B1%7D%7B%28x%2Bh%29%7D-%5Cfrac%7B1%7D%7Bx%7D%20%20%7D%7Bh%7D)
=
![\frac{\frac{x-(x+h)}{x(x+h)} }{h}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cfrac%7Bx-%28x%2Bh%29%7D%7Bx%28x%2Bh%29%7D%20%7D%7Bh%7D)
=
![\frac{\frac{x-x-h}{x(x+h)} }{h}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cfrac%7Bx-x-h%7D%7Bx%28x%2Bh%29%7D%20%7D%7Bh%7D)
=
← cancel h on numerator/ denominator
= -
Answer:
10players
Step-by-step explanation:
Using the concept of probability
probability = expected outcome/total outcome
Total outcome s the numbers of players on the team
Given
Total number of trophy won = 7 (expected)
Fraction of those that won = 7/10 (probability)
Substitute
7/10 = 7/total outcome
1/10 = 1/total outcome
Reciprocate both sides
10/1 = total outcome
Swap
Total outcome = 10
Hence the number of players on the team is 10players
