Explanation;
Sales tax is computed as the product of the price times the tax rate in % divided by 100:
- Sales tax = price × tax rate / 100
Here is each compute:
- $299 × 4% = $299 × 4/100 = $11.96
- $6,750 × 7% = $6,750 × 7/100 = $ 472.50
- $76.50 × 5.2% = $76.50 × 5.2/100 = $3.98
- $18.32 × 3.9% = $18.32 × 3.9/100 = $0.71
- $5.95 × 6.2% = $5.95 × 6.2/100 = $0.37
- $13.89 × 4.3% = $13.89 × 4.3/100 = $0.60
- $768.43 × 3.7% = $768.43 × 3.7/100 = $28.43
- $6.49 × 5.8% = $6.49 × 5.8/100 = $0.38
- $23.86 × 7.1% = $23.86 × 7.1/100 = $1.69
Answer:
steps below
Step-by-step explanation:
cot 10° * cot 20° * cot 70° * cot 80° * cot 45°
= (cos 10°/sin 10°)*(cos 20°/sin 20°)*(cos 70°/sin 70°)*(cos 80°/sin 80°)* (1)
= (cos 10°*cos 80°)(cos 20°*cos 70°) / (sin 10°*sin 80°)(sin 20°*sin 70°)
= (1/2*(cos60°+cos90°)*1/2(cos50°+cos90°))/(1/2*(cos60°-cos90°)*1/2(cos50°-cos90°)) ... cos90° = 0 cos60° = 1/2
= (1/8*cos50°) / (1/8*cos50°)
= 1
