Answer:
273.7
Step-by-step explanation:
first fine the sides that isn't the base.
triangle area formula: (b*h)/2
(14*9)/2 = 63
since there are 3 sides you multiply this by three.
63*3=189
then find the base.
same formula since its a triangle.
(12.1*14)/2 = 84.7
now add them both up:
84.7+189 = 273.7
hope this helps!
Answer:
Only 16 problems correct
Step-by-step explanation:
Well I thought that since 80% is 4/5 then I should do 20 divided by 5 which will get me 4 and since I'm doing 4/5 I should go all the way up to 80% of 20 which will get me 16.
I'm not making that much sense but
Hope this helps :)
Answer:
the maximum concentration of the antibiotic during the first 12 hours is 1.185
at t= 2 hours.
Step-by-step explanation:
We are given the following information:
After an antibiotic tablet is taken, the concentration of the antibiotic in the bloodstream is modeled by the function where the time t is measured in hours and C is measured in 

Thus, we are given the time interval [0,12] for t.
- We can apply the first derivative test, to know the absolute maximum value because we have a closed interval for t.
- The first derivative test focusing on a particular point. If the function switches or changes from increasing to decreasing at the point, then the function will achieve a highest value at that point.
First, we differentiate C(t) with respect to t, to get,

Equating the first derivative to zero, we get,

Solving, we get,

At t = 0

At t = 2

At t = 12

Thus, the maximum concentration of the antibiotic during the first 12 hours is 1.185
at t= 2 hours.
