Answer:
The answer would be, 81cm.
Step-by-step explanation:
36÷4=9
9×9=81
To answer this you need to find the LCD (least common denominator) 2/3times4=8/12 and 3/4times3=9/12 and 9+8=17 then 17-12=5 so she bought 1 5/12 yards of ribbon
Answer:
tep-by-step explanation:
In order to find the integral:
we can do the following substitution:
Let's call
Then
which allows us to do convert the original integral into a much simpler one of easy solution:
Therefore, our integral written in terms of "x" would be:
The time when the maximum serum concentration is reached is obtained by equating the derivative of C(t) to 0.
i.e. dC(t)/dt = 0.06 - 2(0.0002t) = 0.06 - 0.0004t = 0
0.0004t = 0.06
t = 0.06/0.0004 = 150
Therefore, the maximum serum concentration is reached at t = 150 mins
The maximum concentration = 0.06(150) - 0.0002(150)^2 = 9 - 0.0002(22,500) = 9 - 4.5 = 4.5
Therefore, the maximum concentration is 4.5mg/L
