Domain: Set of all real numbers
Range:

where y is a real number
---------------------------------------------------
The domain is the set of real numbers because there are no restrictions on what to plug in for x. There are no gaps, holes, jumps, or asymptotes. The graph continues on in both directions stretching to both infinities (this is indicated by the arrows on the curve ends)
The range is the set of y values between -1 and 1 because this is the set of y outputs. The largest y can get is +1 or just 1. The smallest y can get is -1. The value of y can be any number in between as there are no gaps. <span />
Step-by-step explanation:
Given diameter of table (circular) =1.6m
radius =0.8m
area of circle = πr
2
=3.14×0.64=2.0096m
2
Now rate of polishing per meter square =15Rs
Cost of polishing table top = 15×2.0096
cost = 30.14m
2
15 - 8
8 + 2 is 10, so there are 5 leftover. 2 + 5 is 7, so 8 + 7 is 15.
Answer:
1/8
Step-by-step explanation:
Probability of pulling a nickel the first time: 5/10
Probability of pulling a nickel the second time: 5/10 (remember that you are replacing)
Probability of pulling a dime the third time: 5/10
Total probability: 5/10 * 5/10 * 5/10 OR 1/2 * 1/2 * 1/2 = 1/8
im pretty sure this is the answer! i hope this helps! <3
