Answer:
cosA + sinA
Step-by-step explanation:
Using trig. identities :
cos(A + B) = cosAcosB - sinAsinB
cos2A = cos²A - sin²A
cos2A = (cosA + sinA)(cosA - sinA)
Therefore, your question is :
=> cos2A/(cosA - sinA)
=> (cosA + sinA)(cosA - sinA)/(cosA - sinA)
=> cosA + sinA
Answer:
<em>36%</em>
Step-by-step explanation:
"8 kg of mixed nuts containing 26% peanuts"
weight of peanuts: 26% * 8 kg = 0.26 * 8 kg = 2.08 kg
"5 kg ... that contain 52% peanuts"
weight of peanuts: 52% * 5 kg = 0.52 * 5 kg = 2.6 kg
Total weight of peanuts: 2.08 kg + 2.6 kg = 4.68 kg
Total weight of mixed nuts: 8 kg + 5 kg
percent of peanuts: (4.68 kg)/(13 kg) * 100% = 36%
