Help ASAP please!!!!

Answer:

There are 327,811 doctors.

Step-by-step explanation:

Percentage of female doctors = 16.9%

Number of female doctors = 55,400

Percentage of Male doctors = 100-16.9%

                                               =83.1%

So if 55,400 doctors are represented by 16.9 how many doctors are represented by 100%?

100% represents total number of doctors.

⇒\frac{55,400}{16.9} \times100

=327,810.65

Number of doctors has to be a whole number so we rounf off the number to nearest whole number:

Therefore there are 327,811 doctors.

Which is equivalent to sin^-1(tan(pi/4)) ? Give your answer in radians.
aleksklad [387]
We are to find the value of sin^{-1}(tan( \frac{ \pi }{4}))

First we evaluate tan(π/4). The value of tan(π/4) is 1. 

So, 

sin^{-1}(tan( \frac{ \pi }{4})) =sin^{-1} (1)

sin(π/2) = 1
So,
sin^{-1}(1)= \frac{ \pi }{2}

Thus, we can write:

sin^{-1}(tan( \frac{ \pi }{4}))= \frac{ \pi }{2} radians.

So, the answer to this question is π/2 radians.
