Answer:
0.9212 (Answer b)
Step-by-step explanation:
Note that sin 52 deg 47 min = sin (52 47/60 deg)
Using the fact that pi radians = 180 degrees, convert the argument of the sine function to radians:
sin ( [52 47/60][pi rad][180 deg] )
= sin ( 0.2932 pi) = 0.9212
Using a calculator to evaluate this, we get 0.2891
Answer:
Option 1, 2 and 4
Step-by-step explanation:
3x-4y-8= 12
3x-4y= 12+8 (bring constants to 1 side)
3x-4y= 20 (simplify)
For a point to be a solution of the above equation, substitute the x and y coordinates into 3x-4y and see if it equals to 20.
Option 1: (0, -5)
3(0)-4(-5)= 20
This is correct
2) (4, -2)
3(4)-4(-2)=20
This is correct
3) (8,2)
3(8)-4(2)= 16
This is incorrect.
4) (-16, -17)
3(-16)-4(-17)= 20
This is correct.
5) (-1, -8)
3(-1)-4(-8)= 29
This is incorrect.
6) (-40, -34)
3(-40)-4(-34)= 16
This is incorrect.
