Hi there!
Let me help you out a bit here. What we need to do is subtract the area of the smaller square from the area of the larger square. To do this, we first need to find the length of one of the larger sides. Since the outer polygon is a square, we can use the 45-45-90 relationship to determine that each side of the larger square is equal to

. Next, we can do the same thing for the smaller square, determining that one outer side of the smaller square is equal to

. To figure out the area of both squares, we need to square each of the outer lengths. This gives us 162 for the bigger square and 32 for the smaller square. Now, all we need to do is subtract 32 from 162. This gives us a value of 130cm^2 for the shaded area.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
Answer:
Option A.
Step-by-step explanation:
Consider the below figure attached with this question.
Scenario 1 represented by the graph.
From the graph it is clear that the line passes through the points (1,60) and (2,120).
Slope of the line is
The slope of line is 60. It means the speed is 60 miles per hour.
Scenario 2 defined by the equation,
If an equation defined as
, then m is slope and b is y-intercept.
The slope of line is 50. It means the speed is 50 miles per hour.
The slope of Scenario 1 is greater than slope of Scenario 2. So, the Scenario 1 shows the greater speed.
Hence, the correct option is A.
It is the second function:
y=(1/2)^(x-3)
When x=0, the exponent is -3. (1/2)^-3 is 8.
y = 8+1 = 9
