Answer:
The answer is c because there is not suppose to be a negative number
Step-by-step explanation:
You need to find circumference, so you would multiply the diameter by pi. So your answer is 212pi feet or 666.02 feet
Answer:
The Slope is calculated Using the formula

The line passed through (5, 7) and (8, 8):
The slope is

The slope equals

I don’t understand your questions because it’s all connected together. Could you maybe separate the actual question in the comments for me to help?
Answer:
between x=-1.5 and x = 0
between x = 0 and x = 1.5
Step-by-step explanation:
For the interval -1.5 < x < 1.5, we can see that the slope is negative (i.e from top left to bottom right). Hence it can be said that the graph is decreasing during this interval.
For the other parts of the graph (as shown) the slope is positive (i.e from bottom left to top right). in those areas, the graph is increasing.
