Answer:
20.6 km
Step-by-step explanation:
Using (East, North) coordinates, the hiker's position ends up being ...
22.2(cos(-45°), sin(-45°)) +40.1(cos(65°), sin(65°))
We're only interested in the second coordinate of this total, which is ...
22.2sin(-45°) +40.1sin(65°) ≈ -15.698 +36.343 = 20.645 . . . km
The y-component of the hiker's position at the end of the second day is 20.6 km north of her starting location.
I don't know sorry I tried to work it but didn't work
Set to zero
0=4x^2+24x+11
factor
use ac method
muliplty 4 and 11
44
what 2 numbers multily to get 44 and ad to get 24?
2 and 22
0=4x^2+2x+22x+11
0=(4x^2+2x)+(22x+11)
0=2x(2x+1)+11(2x+1)
0=(2x+11)(2x+1)
set to zero
2x+11=0
2x=-11
x=-11/2
2x+1=0
2x=-1
x=-1/2
x=-11/2 and -1/2
Answer:
no
Step-by-step explanation:
because they didnt spin the same things
