So, in order to round the the tens, we need to look at the ones place.
So we look at the underlined digit and see if it is 5 or higher (it is)
289<u>5</u>
So, since it's 5, we raise the next place up. so now the 10's place has 10, so we need to raise the next place up further.
2900
when 2 lines meet to make a 90 degree angle
6 + 8 = 14.
You have 6, then just count up 8 times, and then you will get 14.

Answer:
about 0.177 mg/mL
Step-by-step explanation:
The maximum is found where the derivative of C(t) is zero.
dC/dt = 1.35e^(-2.802t) -(1.35t)2.802e^(-2.802t) = 0
Solving for t gives ...
t = 1/2.802
So, the maximum C(t) is ...
C(1/2.802) = 1.35/2.802e^(-1) ≈ 0.177 . . . . . mg/mL
The maximum average BAC during the first 6 hours is about 0.177 mg/mL.

The maximum occurs about 21 minutes 25 seconds after consumption.
