We will use the Pythagorean theorem to determine the height:

Finally:

Answer Ladder will reach the height of 14.59 feet ( to the nearest hundredths).
Answer
Option (A) is correct .
Reason
The formula for the slope.

As given
Line AB contains (0, 4) and (1, 6) .
put in the slope formula


Slope of the AB is 2.
As given
Line CD contains points (2, 10) and (−1, 4).
put in the slope formula


Slope = 2
Slope of the CD is 2.
As the slope of the AB contains (0, 4) and (1, 6) Line CD contains points (2, 10) and (−1, 4) is 2 .
Therefore the option (A) is correct i.e the lines are parallel because the slopes are the same.
Answer:
D: -35
Step-by-step explanation:
Take the sign of the larger which is negative.
subtract 99-64 to get 35.
Add your negative sign to get -35.
5x[$25.85-($25.85 x 0.10) ] + (5 x 2.50)=$128.83 compared to[ 5 x 27.36( $27.36 x 0.15)]+ 10.00= 126.28 is the least amount.
answer is ------> $126.28
