Answer:
-22.5

Explanation:
Use the average rate of change equation
f(b)-f(a) / b-a
f(b) = f(0) = 3(.25)^0 = 3
f(a) = f(-2) = 3(.25)^-2 = 48

(3-48)/ 0-(-2)
(-45) / 2
-22.5

!!!!Cosines / sines . Find a and round to the nearest 10th.

I think Erica said I messed this one up. It looks the same. Oh yeah I think this was the one I thought $a=1.8=3\sqrt{2}-\sqrt{6}$ , Answer: 1.8.

Let's do it again.

$\dfrac{a}{\sin(180 - (15+105))}=\dfrac{2}{\sin 105^\circ}$

$a = \dfrac{2 \sin(60)}{\sin 105^\circ}$

$a \approx 1.8$

Yes, same as before.
