Answer:
4π or about 12.56
Step-by-step explanation:
The circumference of a circle is calculated with diameter so we first need to find the diameter. Going from radius to diameter can be done by multiplying by 2, therefore 2*2=4 so the diameter is 4.
Now that we have the diameter we need to use the formula for circumference which is c=4*π. Because the question doesn't state to use 3.14 to multiply then you would usually use 4π as your answer but if you were to use 3.14 then you would get a circumference of 4*3.14=12.56.
Answer:
Product of powers
Step-by-step explanation:
Answer:
Step-by-step explanation:
The key here is to find out how much he makes per hour. We can find that out using the info given.
286 = 13x so
x = 22 dollars per hour. For 7 hours of work then,
7(22) = $154
The domain of a function are its possible input values
The domain of the function is <em>(b) all real numbers greater than or equal to 0.</em>
From the graph, we have the following observations
- <em>t represents time (it is plotted on the x-axis)</em>
- <em>t starts at 0</em>
- <em>t has no end</em>
The above observations imply that; the domain starts from 0
Hence, the domain of the function is the set of all real numbers greater than or equal to 0.
