72/5 = 14.4 final answer
Answer:
38 quarters
Step-by-step explanation:
0.25 x 63 = 15.75
0.05 x 63 = 3.15
----------------------------
0.25 x 50 = 12.50
+ = $13.15
0.05 x 13 = 0.65
----------------------------
0.25 x 25 = 6.25
+ = $8.15
0.05 x 38 = 1.90
----------------------------
0.25 x 30 = 7.50
+ = $9.15
0.05 x 33 = 1.65
--------------------------
0.25 x 35 = 8.75
+ = $10.15
0.05 x 28 = 1.40
-------------------------
0.25 x 38 = 9.50
+ = $10.75
0.05 x 25 = 1.25
------------------------------
I hope this helps!
Answer:
Step-by-step explanation:
Applying the chain rule
Then it becomes
In x=0
![\frac{d[tex]f'(0)=-f'(0)\\f'(0)+f'(0)=0\\2f'(0)=0\\](https://tex.z-dn.net/?f=%5Cfrac%7Bd%5Btex%5Df%27%280%29%3D-f%27%280%29%5C%5Cf%27%280%29%2Bf%27%280%29%3D0%5C%5C2f%27%280%29%3D0%5C%5C)
f}{dx} =-\frac{df}{dx}[/tex]
Then
