Answer:
3
Step-by-step explanation:
Given
f(x) = , then
f(12) = = = ± 3
There are 2 values 3 and - 3
The positive value of f(12) is + 3
1yr 47,000, 2nd yr 48,880, 3rd yr 51,617.28, 4th yr 57,346.7981 or 57,346.80
1yr 47,000
2nd yr 47,000 x 4% = 48,880
3rd yr 48,880 x 5.6% = 51,617.28
4th yr 51,617.28 x 11.1% = 57,346.7981 or 57,346.80
f = 119
e = 61
d = 90
109
line AB is 180 degrees because a circle is 360 degrees and half a circle is 180 degrees.
Add 42 degrees and 29 degrees. 42+29 = 71
Then subtract. 180 - 71 = 109
So therefore
Hope this helps:)
