Y = log x / x
y ` = (( log x )` * x - (x)` * log x) / x²=
= (1/x * x - 1 * log x ) / x² =
= ( 1 - log x ) / x²
y ` = 0;
1 - log x = 0
log x = 1
x = e
The maximum value:
y max = log e / e = 1 / e
Answer:
False
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
here m = - , hence
y = - x + c ← is the partial equation
to find c substitute (- 3, 5) into the partial equation
5 = + c ⇒ c =
y = - x + ← equation of line
Answer:
13n+20
Step-by-step explanation:
If 20 is the flat rate, then you dont put x to it. X is how many books you are going to get and 13 is how much you have to pay for each book. If that makes sense.

Answer:
Step-by-step explanation:
t(1) = 4
t(n) = -4 * t(n - 1)
common ratio: -4
t(1) = -4 * t(0)
4 = -4 * t(0)
t(0) = -1
t(n) = -4n * -1
t(1) = -4 (1) * -1
= 4
t(n) = -4n * -1
t(6) = -4*6 * -1
t(6) = 24
