Answer:
8000
Step-by-step explanation:
I did a simple way, I divided 4800 by 3 and got 1600, then multiplied 1600 by 5. Because 2x5 =10 (or 100%)
I’ve done these questions before and i’ve gotten confused because I have trouble with nagative numbers but i’ve gotten better st it. It’s -5

Answer:
w = π/2
Step-by-step explanation:
I used trig identities (double angle) to solve this problem.
Step 1: Rearrange problem
2cos²(w) - cos(w) - 1 = 0
2cos²(w) - 1 - cos(w) = 0
Step 2: Trig Identity
cos2w - cos(w) = 0
Step 3: Combine like terms
cosw = 0
Step 4: Solve
w = cos^-1(0)
w = π/2
I may have done it wrong so don't rely too much on me
