Answer:
e^-1.6094 = 0.2
Step-by-step explanation:
The inverse of In is e
If In 0.2 = -1.6094
Then e^-1.6094 = 0.2
Without the tip it was $60. If you are being asked to add the tip it will be $69
67.943
= 60.000 + 7.000 + 0.900 + 0.040 + 0.003
0 = 0
The input is an identity: it is true for all values
Answer:
see explanation
Step-by-step explanation:
Given
tan a =
= 
We require the hypotenuse h
Using Pythagoras' identity
h² = 9² + 40² = 81 + 1600 = 1681 ( take square root of both sides )
h =
= 41 , thus
sin a =
= 
cos a =
=
