Answer:
Part a) The table in the attached figure (see the explanation)
Part b) see the explanation
Step-by-step explanation:
Let
y ----> the total cost of Lift Tickets
x ----> the number of days
we know that
The linear equation in slope intercept form is given by

where
m is the slope or unit rate of the linear equation
b is the initial value or y-intercept pf the linear equation
In this problem we have
The slope is equal to

The y-intercept is equal to

substitute

<u><em>Complete the table</em></u>
Find the value of y for each value of x
For x=0 day

For x=1 day

For x=2 days

For x=3 days

For x=4 days

For x=5 days

For x=6 days

Part b) Explain how you know the data in the table above is linear
The data in the table is linear, because satisfy the equation of the linear equation

where
x is the variable independent or input value (the number of days)
y is the variable dependent or output value (the total cost of Lift Tickets)
The area of semi-circle is 8π cm² with diameter of 8cm.
What is area of semi-circle?
- The area that the semicircle occupies is that which is contained inside its perimeter. Half of a circle is a semicircle.
- The area of a semicircle will therefore be equal to half that of a circle. Both the radius and the diameter can be used to get the semicircle's area.
- The formula used to determine a semicircle's area in terms of radius "r" is written as follows:
Area of circle = πr²/2
- Area of semi-circle= πd²/8 is the formula used to determine a semicircle's area in terms of its diameter.
- The value of the constant is 22/7, or 3.14.
Given:
Diameter = 8cm
Area of semicircle = πd² / 8
=π8² / 8
= 8π cm²
Hence, the area of semi-circle is 8π cm².

The ratio of circumference to diameter of a circle is π, about 3.14. The diameter of the circular park will be about (62.8 m)/3.14 = 20 m.
The park is 20 m across at the widest point.
