<h2>
Answer:</h2>
Shown below
<h2>
Step-by-step explanation:</h2>
The most famous of the step functions is the greatest integer function, which is denoted by the parent function
.
So, this function is defined as:
.
These are the characteristics of this function:
- The domain of the function is the set of all real numbers.
- The range of the function is the set of all integers.
- The graph has a
at
and
in the interval
- The graph is constant between each pair of consecutive integers.
- The graph jumps vertically one unit at each integer value.
The function
represents the parent function shifted 2 units downward. Therefore, the correct option has been chosen in the attached figure.
A's area is 4x3=12, B=2x3=6, so yes, A is twice the area of B
a Answer: YES
b Answer: One side doubled, the other stayed the same, so area doubled.
I think it’s (3,4) the third answer
The picnic area is 20 inches wide in the drawing in her scale of 1 inch : 4 yards.
<h3>What is unitary method ?</h3>
Unitary method is a technique for first solving the value of a single digit unit and from there we can find the value of any given unit.
According to the given question lillian drew a scale drawing of a county park. the scale she used was 1 inch : 4 yards.
The picnic area is 80 yards wide in real life.
∴ The width of the picnic area in here drawing in inches will be
= 80/4 inches.
= 20 inches.
