Answer:
A) y = 4
Step-by-step explanation:
Line AB is a vertical line, so a line perpendicular to it would have to be a horizontal line (perpendicular lines make an "x" shape with one another). Horizontal lines are written as y = ___ .
The perpendicular line also has to pass through the point (2,4). Points are written as (x, y). Therefore, the y-value in (2,4) is 4.
The perpendicular line has to be y=4 since it passes through both the Line AB and the given point.
Answer:
Mary would have a rise of 12 and a run of 4, making her slope, or rate of change, $3 a day. Julie would have a rise of 19 and a slope of 6, making her slope, or rate of change, $3.17 a day. Since Julie is raising money at a faster rate, she would get to the goal of $1000 first.

Answer:
14
Step-by-step explanation:
The law of cosines is a² = b²+c²-2bc(cos A).
We will use s in place of a, since it is the unknown side. This makes b and c 8 and 9.
Angle A will be the angle opposite side a, or in this case side s. This makes it 111.
This gives us
s² = 8²+9²-2(8)(9)(cos 111)
s² = 64+81-2(8)(9)(cos 111)
s² = 145-144(cos 111)
s² = 196.605
Take the square root of each side:
√(s²) = √(196.605)
s = 14.02 ≈ 14
Multiply the lengths of two sides together
