The rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same. For example, when point P with coordinates (5,4) is reflecting across the X axis and mapped onto point P', the coordinates of P' are (5,-4).
Answer:
Width = 30
Step-by-step explanation:
Area = 18x * 10y = 180xy
Length = 6xy
Width = ?
Since the shape of the office complex is a rectangle,
Area of a rectangle = length × width
180xy = 6xy × width
Width = 180xy / 6xy
Width = 30

What is the recursive formula for this geometric sequence 2, -10, 50, -250, .... ?
The recursive formula for this geometric sequence is:
= 2;
= (-5) • 
Step-by-step explanation:
To find the recursive formula for a geometric sequence:
- Determine if the sequence is geometric (Do you multiply, or divide, the same amount from one term to the next?)
- Find the common ratio. (The number you multiply or divide.)
- Create a recursive formula by stating the first term, and then stating the formula to be the common ratio times the previous term.
The recursive formula is:
= first term;
= r •
, where
is the first term in the sequence
is the term before the nth term - r is the common ratio
∵ The geometric sequence is 2 , -10 , 50 , -250
∴
= 2
- To find r divide the 2nd term by the first term
∵ 
∴ 
- Substitute the values of
and r in the formula above
∴
= 2;
= (-5) • 
The recursive formula for this geometric sequence is:
= 2;
= (-5) •
