Answer:
B
Step-by-step explanation:
the arc length is calculated as
arc = circumference of circle × fraction of circle
= 2πr × 
= 2π × 16 × 
= 32π × 
= 
= 8π ft
Answer:x>7
Step-by-step explanation:
Its saying a nuber greater than 7 and 3 plus 8 would be 11
First use slope formula, y2 - y1 / x2 - x1 on the points, 4-2 / 4-3, the slope is 2. then plug this into the equation y = mx + b where m is the slope. use one of the points to solve for b, i will use (3, 2). 2 = 2(3) + b. Solving for b, you would get b = -4. so now you have everything you need, the equation would be y = 2x - 4
The range would be {3, 5, 7} because the range, is basically "y". It's all the possible "y" values in a function.
