Answer:
Part 1) The expression for the perimeter is or
Part 2) The perimeter when z = 15 ft. is
Step-by-step explanation:
Part 1)
we have
Find the roots of the quadratic equation
Equate the equation to zero
Complete the square
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Factor the leading coefficient
Complete the square. Remember to balance the equation by adding the same constants to each side
Rewrite as perfect squares
-----> root with multiplicity 2
so
The area is equal to
The length side of the square is
therefore
The perimeter is equal to
Part 2) Find the perimeter when z = 15 ft.
we have
substitute the value of z
The graph of g(x) is gotten by translating the function f(x) = |x| down by 3 units to get to function g(x)
<h3>How to graph the equation of the function?</h3>The equation of the function is given as; g(x) = |x| - 3
The above function is an absolute value function.
The parent function of an absolute value function is; f(x) = |x|
This means that the function f(x) is translated to get to function g(x)
In this case, the function is f(x) is translated down by 3 units to get to function g(x)
So, the graph of g(x) is gotten by translating the function f(x) = |x| down by 3 units to get to function g(x)
See attachment for the graph of g(x)
