Answer:
51 1/35 ft²
Step-by-step explanation:
Area of a rectangle = length x width
6 5/7 x 73/5
to multiply both figures, convert the mixed fractions to an improper fraction
to convert to improper fraction, take the following steps :
1. Multiply the whole number by the denominator
2. Add the numerator to the answer gotten in the previous step
3. divide the number gotten in the previous step by the denominator
47/7 x 38/5 = 1786 / 35
convert the improper fraction to a mixed fraction = 51 1/35 ft²
Answer:
Three zeros 
x-intercepts: (-4,0), (1,0), (6,0)
Step-by-step explanation:
Plot the graph of the function
on the coordinate plane. This graph intersects the x-axis at three different points (see attached diagram):
This means
are zeros of the function 
Period of sin wave = 1/2
Period of parent sine function is 2π.
This means the x value of sine function (sin(x)) has to be divided by 4π to get a period of 1/2 because 2π/4π = 1/2
Thus, our function will be of the form:

Maximum Value = 10
Minimum Value = -4
Amplitude of the function = (Maximum Value - Minimum Value)/2
So, amplitude of the function is 7
Thus, the function will be of the form:

The function has a y-intercept other than zero, this means the function will be of the form:

The y-intercept is 3. This means for x=0, y=3. Using the values, we get:
Thus the equation of the sinusoidal function becomes:
I think the answer is number 3
