With some simplification,
cos⁻¹(x) - 5 cos⁻¹(x) - π/3 = 2π/3
becomes
-4 cos⁻¹(x) = π
or
cos⁻¹(x) = -π/4
However, the inverse cosine function has a range of 0 ≤ cos⁻¹(x) ≤ π, so there are no solutions to this equation.
The correct answer should be steeper
Answer:
2200 Square Yards
Step-by-step explanation:
Dimension of the Youth Soccer Field = 110 yards long and 60 yards wide.
- Therefore Area of the Youth Soccer Field = 110 X 60 =6600 Square Yards
Dimension of the professional soccer field =110 yards long and 80 yards wide.
- Area of the professional soccer field = 110 X 80 =8800 Square Yards
The difference in their Area = 8800-6600=2200 Square Yards
Therefore, the professional soccer field has an area of 2200 Square Yards more than the youth soccer field.
