Answer:
The answer is 3.53
Step-by-step explanation:
The formula for a semicircle is pi x r2 divided by 2, so divide the diameter by 2, then plug that in as the radius into the formula.
Domain is X’s, Y’s are Range so
a) Domain: 4.2, 5, 7, 4.2
Range: 1.5,2,8,0
b) Domain:-1,-2,4,7
Range: 1,2,-4,-7
What does <em>x </em>stand for?
If you break it down it goes to 2 laps every 5 minutes. So any set that follows this "pattern" would be proportional
Answer: 
Step-by-step explanation:
Because it is asking for a line, it cannot be the first option (which is a quadratic) or the fourth option (which is an exponential).
This leaves us with the second and third options.
Since the line will have a negative slope (as the data is decreasing), this means that the only viable option is
