Answer:
Step-by-step explanation:
-4x + 1 = -4x + 1
1 = 1
infinitely many solutions
10 oranges = $1
5 oranges = $?
To get from 10 to 5 you divide by 2 so that’s what you do with the $1 so it would be $0.50
I think the answer you are looking for is 99%.
100 + 10% = 110. 110 - 10% = 99. that’s how i got 99.
Take the deritivive
remember
the deritivive of f(x)/g(x)=(f'(x)g(x)-g'(x)f(x))/(g(x)^2)
so
deritiveive is ln(x)/x is
remember that derivitive of lnx is 1/x
so
(1/x*x-1lnx)/(x^2)=(1-ln(x))/(x^2)
the max occurs where the value is 0
(1-ln(x))/(x^2)=0
times x^2 both sides
1-lnx=0
add lnx both sides
1=lnx
e^1=x
e=x
see if dats a max or min
at e/2, the slope is positive
at 3e/2, the slope is negative
changes from positive to negative at x=e
that means it's a max
max at x=e
I realize I didn't find the max point, so
sub back
ln(x)/x
ln(e)/e
1/e
the value of the max would be 1/e occuring where x=e
4th option is answer (1/e) because that is the value of the maximum (which happens at x=e)
Answer:
20.4375 miles
Step-by-step explanation:
5 miles / 8 <u>km</u> * 32.7<u> km</u> = 20.4375 miles
( see how the units 'km' cancel out and you are left with 'miles' as your answer?)
