The shape is composed of three squares and two semicircles.Select all the expressions that correctly calculate the perimeter of
1 answer:
Answer:
100+20π
Step-by-step explanation:
Refer to the attached diagram.
Perimeter of a square = 4L
where L represents the length of a square's side
According to the diagram;
L = 10
Thus, Perimeter of one square = 4(10) = 40
Consequently, the perimeter of three squares combined = 3(40) = 120
Two semicircles create one full circle
The perimeter of a circle is given by the formula 2πr
Here, the radius of the circle equals the length of a side of the square.
Area of the circle = 2π(10)= 20π
The complete perimeter of the shape is therefore the perimeter from the two semicircles combined with that of the four squares = 100+20π

Detailed Explanation:
We have two distinct functions to analyze:
This function delineates the earnings based on units of x
Then the second function is
which illustrates the quantity of gallons of ice cream produced by Barrett each hour, with x representing the hours worked.
Our aim is to determine the composite function
resulting from substituting the output of as input for
. Within this framework, the function
signifies the amount of money accrued per number of working hours, x.
By substituting g(x) into the x variable of f(x), we obtain:
