The correct answer is D, since a rotation of 360 has no effect, since the figure does a whole turn and returns where it was.

So here if a is -2 and b is 6 .
1. 6a -b =
Here you have to apply this method called substitution, the meaning is that you have exchange the variables with numbers given you above . So is going to be 6(-2) - 6 which is equal to -12 - 6, this the answer but if the question said find and solve the answers it will be -6

A cup of coffee contains about 100 mg of caffeine. Caffeine is metabolized and leaves the body at a continuous rate of about 12%
Mamont248 [21]

Answer:

a. A = C_{0}(1-x)^t\\x: percentage\ of \ caffeine\ metabolized\\

b. \frac{dA}{dt}= -11.25 \frac{mg}{h}

Step-by-step explanation:

First, we need tot find a general expression for the amount of caffeine remaining in the body after certain time. As the problem states that every hour x percent of caffeine leaves the body, we must substract that percentage from the initial quantity of caffeine, by each hour passing. That expression would be:

A= C_{0}(1-x)^t\\t: time \ in \ hours\\x: percentage \ of \ caffeine\ metabolized\\

Then, to find the amount of caffeine metabolized per hour, we need to differentiate the previous equation. Following the differentiation rules we get:

\frac{dA}{dt} =C_{0}(1-x)^t \ln (1-x)\\\frac{dA}{dt} =100*0.88\ln(0.88)\\\frac{dA}{dt} =-11.25 \frac{mg}{h}

The rate is negative as it represents the amount of caffeine leaving the body at certain time.

Answer:

10^6^*^3\\\\or\\\\10^1^8

Step-by-step explanation:

the 6th power of 10 would be 10^6, then you'd multiply it by 3 which would make it 10^6*3

you could then simplify it and say 10^18 (multiply the exponents [6 and 3])
