A = LW
A = 28 × 7.1
A = 198.8
The correct answer is A.
The decimal multiplier to decrease by 30 is .7
Answer:
Step-by-step explanation:
Tan can be defined as: 
as it simplifies to opposite/adjacent. If you know a bit about the unit circle, you'll know that the x-coordinate is going to be cos(theta) and the y-coordinate is going to be sin(theta). Since the sin(theta) is defined as opposite/hypotenuse, and the hypotenuse = 1, so sin(theta) is defined as the opposite side, which is the y-axis. Same thing goes for cos(theta), except the adjacent side is the x-axis.
Using this we can define tan
Answer:
D
Step-by-step explanation:
the y intercept is negative 3, and the line is going down, and it would be negative 3 over 2.
Answer:
The line segments are parallel.
Step-by-step explanation:
First, I never have graph paper when it is needed so I suggest Geogebra.com.
Now slope is found by rise over run so I took the points on the graph and counted where they intersected with any other points on the line. AB was 2/1 which means 2. I did the same for the other line segment and found 2/1 : 2. so both of the slopes are the same so you have parallel lines.
