We are looking for the inner perimeter of the track. Since there are two semicircles, these mix to form one full circle so we can use the formula to find the circumference of the circle with a diameter of 60 m, which was given to us. With a diameter of 60m, the radius will be 30m. Now we can solve this problem.
C = 2πr
C = 2π(30)
C = 60π
The semicircle ends of the track are a distance of 60π m, and now we just need to add the lengths of the inner track which are 100 m each. So:
P = 60π + 100m + 100m
P = 200 + 60π
P = 388.5 m
For a relation to be a function it must be
relation is not a function.
In the above options, C is
relation therefore cannot be a function.
The reason is that 3 alone maps onto -2 and 5, in the ordered pairs (3,-2) and (3,5). This disqualifies it from being a function.
Hence the graph of this relation will not pass the vertical line test
Answer:
12.5
Step-by-step explanation:
put them in order from least to greatest: 11, 11, 12, 12, 12, 13, 13, 14, 15, 16
the middle is 12 and 13 so you do 12+13 then divide by 2
to get 12.5
hope this helps
Answer:
72 degrees
Step-by-step explanation:
180-108=72
where I got 180: a supplementary angle is 180 degrees
Hello!
So let's first start out by solving the left side of the equation:
2 to the third power is 8
The right side now: -3 to the second power is -9
In total: 8- (-9)
So your answer is C) -1
I hope it helps!
