Answer:
First option: cos(θ + φ) = -117/125
Step-by-step explanation:
Recall that cos(θ + φ) = cos(θ)cos(φ) - sin(θ)sin(φ)
If sin(θ) = -3/5 in Quadrant III, then cos(θ) = -4/5.
Since tan(φ) = sin(φ)/cos(φ), then sin(φ) = -7/25 and cos(φ) = 24/25 in Quadrant II.
Therefore:
cos(θ + φ) = cos(θ)cos(φ) - sin(θ)sin(φ)
cos(θ + φ) = (-4/5)(24/25) - (-3/5)(-7/25)
cos(θ + φ) = (-96/125) - (21/125)
cos(θ + φ) = -96/125 - 21/125
cos(θ + φ) = -117/125
Answer:
y = - 
Step-by-step explanation:
= 
( cross- multiply )
4y = - 7 ( divide both sides by 4 )
y = -

B.
He can advertise the position by emphasizing that a high initial compensation
will be offered since $13,000 is greater than the previous salary offered to
employees.
C. Yes, I agree because the previous
salary offered was just $10,000 but now it is being increased to $13,000.
