1 answer:

8 0

Standard Equation for trig function: y = A cos (B (x - H))+ K
*Here, we are just dealing with A (amplitude) and B (period)
Period = 2π/ b

8 = 2π/ b
Solve for b: 2π/8 or π/4

Equation: y = 2 cos (π/4 (x))

kupik [55]

Answer:

5/9 acres

Step-by-step explanation:

3 1/3 areas is 10/3

1/6 of the land is covered with beets

$\frac{10}{3} * \frac{1}{6} =\frac{10}{18}$

$\frac{10}{18}$ will simplify to $\frac{5}{9}$

Hence the answer is 5/9 acres
