natka813 [3]

Answer:

C. 4 radians

Step-by-step explanation:

$20=\frac{\pi (Ctrl.Angle)(5)}{180}$

Ctrl Angle = ∅

∅ = $\frac{(20)(180)}{5\pi } =\frac{3600}{5\pi } =\frac{720}{\pi }$

in radians:

VARVARA [1.3K]

Answer:

$39811.77

Step-by-step explanation:

If we put y as the unit of year, the function will be 50000x0.975^y (100%-2.5% is 97.5%). And so from 2001 to 2010, nine years has passed, so the equation will be 50000x0.975^9 And if you calculate and round the answer to the nearest hundredth (cent), you will find $39811.77.
