Answer:
[4, positive infinity)
Step-by-step explanation:
since there is a closed circle on 4, we include 4 in the continuous interval, and we assume that the arrow represents continuity after the graph ends, so the interval of continuity is from 4 to positive infinity.
Explanation:
If your actual answer is very far from your estimate, you probably made a mistake somewhere.

<em>Additional comment</em>
50 years ago, when a slide rule was the only available calculation tool, making an estimate of the result was a required part of doing the calculation. Not only were the first one or two significant digits needed, but also the power of 10 that multiplied them. Use of a slide rule required the order of magnitude be computed separately (by hand) from the significant digits of the result.

You may also find it useful to estimate the error in your estimate. That is, you may want to know the approximate answer to 2 (or more) significant digits in order to gain confidence that your calculation is correct.
Answer:
She would have to work for 33 hours.
Step-by-step explanation:
239.25/7.25=33. Since we are going with hours, this would be 33.
Step-by-step explanation:
135 = <2 + 86 [exterior angle of triangle is equal to the sum of its oppsite two interior angles]
or, <2 = 135 - 86
so, <2 = 49°
Answer:
Plan B
Step-by-step explanation:'
First u have to divide each one to see how much each piano lesson costs.
Plan A- 31.50/6=5.25
Plan B- 20.60/4=5.15
So since Plan B is less then Plan B would be the answer.
