How to calculate the coordinate of point by reflection</h3>
A point if reflected across the line by means of the following formula:
(1)
Where:
- - Original point
- - x-Coordinate of point P
- - Resulting point
If we know that and , then the coordinates of the vertex is:

Answer:
Step-by-step explanation:
The given trapezoid has vertices at A(−1,4), B(0,2), C(1,2) and D(2,4).
The transformation rule for 90° counterclockwise rotation is
This implies that:
This is followed by a translation 3 units to the right.
This also has the rule:
Therefore:
To find the number of terms in the arithmetic sequence, we need to use the formula
where
is the nth number,
is the first number, n is the number of terms and d is the difference of the two consecutive numbers.
7373 = 1313 + (n - 1)(303)
7373 = 1313 + 303n - 303
7373 = 1010 + 303n
7373 - 1010 = 303n
6363 = 303n
6363 ÷ 303 = n
n = 21
Therefore, there are 21 terms in the arithmetic sequence given.
