<u>Answer:</u>
Yes
<u>Step-by-step explanation:</u>
In above image use vertical line test to identify whether a relation is a function or not . Vertical line test means draw various vertical lines in graph and it must cut graph only once i.e. every vertical line must intersect graph only once . if lines intersects graph in more than 1 point than relation is not a function . In short, a relation is a function iff for every value of x there's only one value of y , for any case x has 2 or more than 2 values of y it's <u>not a function.</u>
Answer:
120 minutes
Step-by-step explanation:
the total bill was $58 so we have to subtract the $40 monthly bill part to find how much extra money she paid because her call was over 200 minutes
58-40=18
Then divide the $18 by $0.15 since the $18 is the total amount of each time she was charged $0.15 for going 1 minute over 200 minutes
18÷0.15 = 120
120 is te Amount Of minutes she went over her 200 minute limit
<span>Tan(x)=2
Or for x=45 tan(x)=1
then for tan(x)=2 ; x must be superior to 45
Then the answer is </span><span>d. 63.4 degrees</span>
