Answer:

$sin105 = \frac{ \sqrt{6} + \sqrt{2} }{4}$

$cos105 = \frac{ - { \sqrt{6} + \sqrt{2} } }{4}$

$tan105 = - 2 - \sqrt{3}$

Answer:

Step-by-step explanation:

The y intercept is where x = 0.

X and y are both increasing by 5.

If you add five to the bottom row of the table we see that the next row of the table is x = 0 and y = 13.

This means that (0,13) is the y-intercept and 13 is your correct answer.

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)=10 $e^{-0.173*1}$

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
