Answer:
B
Step-by-step explanation:
we can see that the two lines intersect at the point (1,2)
thus this is the solutions to both lines which is answer B
Money per Charity = $0
Money Left = $814
<u>Give each charity $100</u>
Money per Charity = $100
Money Left = 314
<u>Give each charity $60</u>
Money per Charity = $160
Money Left = $14
<u>Give each Charity $2 </u>
Money per Charity = $162
Money Left = $4
We turn -5,12 into polar coordinates. It's a Pythagorean Triple so
r = 13 Ф=arctan(-12/5) + 180° ( in the second quadrant )
so -5 = 13 cos Ф, 12 = 13 sin Ф
12 sin x - 5 cos x = 6.5
13 sinФ sin x + 13 cos Ф cos x = 6.5
13 cos(x - Ф) = 6.5
cos(x - Ф) = 1/2
cos(x - Ф) = cos 60°
x - Ф = ± 60° + 360° k integer k
x = Ф ± 60° + 360° k
x = 180° + arctan(-12/5) ± 60° + 360° k
That's the exact answer;
x ≈ 180° - 67.38° ± 60° + 360° k
x ≈ 122.62° ± 60° + 360° k
x ≈ { 62.62°, 182.62°} + 360° k, integer k
