Rasek [7]

Answer:

  • B. 1

Step-by-step explanation:

Multiply the first term by x^a, the second term by x^b, the third term by x^c.

<u>The first term becomes:</u>

  • x^a/(x^a+x^b+x^c)

<u>The second term becomes:</u>

  • x^b/(x^a+x^b+x^c)

<u>The third term becomes:</u>

  • x^c/(x^a+x^b+x^c)

<u>Their sum is:</u>

  • (x^a+x^b+x^c)/(x^a+x^b+x^c) = 1

Correct choice is B

12. The function M(h) = 10e-0.173h can be used to find the number of milligrams M of morphine that is
vodomira [7]

Answer:

Part A; Initial dosage is 10 milligrams

Part B:

8.4113 milligrams after 1 hour

5.0057 milligrams after 4 hours.

Step-by-step explanation:

It is given M(h)= 10 e^{-0.173h}

Initial dosage is the 10 milligrams

After 1 hour, plug in h as 1

So, M(1)=10e^{-0.173*1}

Simplify the right side

M(1)=10(0.84113)

M(1)= 8.4113 milligrams.

Now, after 4 hours

M(4)=10 e^{-0.173*4}

M(4)=10(0.50057)

M(4) =5.0057 milligrams

C(5,4)(.40)^4(1-.40)^1=5(.4)^4(.6)^1=0.0768

That's 7.68% = 7.7% (rounded)

Note: C(5, 4) is the number of combinations of 5 things taken 4 at a time. You may have seen this written as _5C_4

In general, C(n,r)=\frac{n!}{r!(n-r)!}
