Answer:
First, a absolute value function is something like:
y = f(x) = IxI
remember how this work:
if x ≥ 0, IxI = x
if x ≤ 0, IxI = -x
Notice that I0I = 0.
And the range of this function is all the possible values of y.
For example for the parent function IxI, the range will be all the positive reals and the zero.
First, if A is the value of the vertex of the absolute function, then we know that A is the maximum or the minimum value of the function.
Now, if the arms of the graph open up, then we know that A is the minimum of the function, and the range will be:
y ≥ A
Or all the real values equal to or larger than A.
if the arms of the graph open downwards, then A is the maximum of the function, and we have that the range is:
y ≤ A
Or "All the real values equal to or smaller than A"
Answer:
-4.2
Step-by-step explanation:
5x+14=-7
5x=-7-14
5x=-21
x=-21/5 or -4.2
Answer:
The percentage error is;
A. 1.79%
Step-by-step explanation:
The given parameters of the rectangular field are;
The length of the field = 62 feet
The width of the field = 25 feet
The width of the gate of the fencing = 9 feet
The actual length of fencing Pete used to fence the field, P₁ = 168 feet
The length of the fencing required in the design, 'P₂' is given as follows;
P₂ = 62 ft. + 62 ft. + 25 ft. + 25 ft. - 9 ft. = 165 ft.
The difference between the actual and design length of fence measurements = P₁ - P₂ = 168 ft. - 165 ft. = 3 ft.
The percentage error in the design measurements compared to the actual fence material used, % Error, is given as follows;
Therefore;
∴ The percentage error of Pete's design measurements compared to the actual fence material used, % Error ≈ 1.79 %.
