Math question

Answer 1

we can write this:
R= requested rate
\[R = \frac{{f\left( {\pi /2} \right) - f\left( 0 \right)}}{{\left( {\pi /2} \right) - 0}} = \frac{{5 - 3}}{{\frac{\pi }{2}}} = ...?\]

Answer 2

\[\Large R = \frac{{f\left( {\pi /2} \right) - f\left( 0 \right)}}{{\left( {\pi /2} \right) - 0}} = \frac{{5 - 3}}{{\frac{\pi }{2}}} = ...?\]

Answer 3

what us the rise in the curve between the points...?

then you know the run is \[\frac{\pi}{2}\]

Answer 4

2/1.57 ?

Answer 5

yes! better is: 4/pi

Answer 6

So the answer is D. 4/pi ?

Answer 7

leave it as an exact value

remember dividing by a fraction means you flip and multiply

\[2 \times \frac{2}{\pi} \]

Answer 8

that's right!
