I’d say 485 discs are defective out of 41000
Answer:
Step-by-step explanation:
ive done this before and the answer to the equation is c and also truss me on this if you want. I wouldnt
10(y+2)-y=2(9y-8)
Mutiply the first bracket by 10
Mutiply the second bracket by 2
(10)(y)(10)(2)= 10y+20
(2)(9y)(2)(-8)= 18y-16
10y+20-y= 18y-16
10y-y+20= 18y-16
9y+20= 18y-16
move 18y to the other side
sign changes from +18y to -18y
9y-18y+20= 18y-18y-16
-9y+20= -16
move +20 to the other side
sign changes from +20 to -20
-9y+20-20=-16-20
-9y= -36
divide by -9
-9y/-9= -36/-9
y= 4
Answer: y= 4
f'(x) =
/ x -
lnx
Differentiate using the product rule
given f(x) = g(x)h(x) then
f'(x) = g(x)h'(x) + h(x)g'(x) ← product rule
g(x) =
⇒ g'(x) = - 
h(x) = lnx ⇒ h'(x) = 
f'(x) =
.
-
lnx
=
/ x -
lnx
