3 0
Answers:
a) 75ml/hr
b) 0ml left

Explanation:
a) 750ml - 450ml = 300ml (This is how much we know the bag drained within 4hrs)

300ml/4=75ml

so now we know the rate of drain is 75ml/hr

b) since rate is 75ml/hr:
75*6=450
450-450=0

Hence there will be no fluid left for the patient.

Use the graph to determine the domain and range of the relation, and whether the relation is a function.
Westkost [7]

Answer:

A

Step-by-step explanation:

We can use vertical line test to determine if a relation is a function.

<em>If a vertical line passes the graph at any point only once, then the relation is a function, if there is even 1 line that passes the graph at 2 points, then it is NOT a function.</em>

<em />

The domain is the set of allowed x-values of the function. The range is the set of allowed y-values of the function.

  • Looking at the graph, we see that there are a lot of vertical lines that cuts the graph two times. Suppose x=3, x=4, x= 5 etc. So it is not a function.
  • As for domain, we see that curve swings from x = -8 to x = 8, so the domain is from -8 to 8.
  • As for range, we that the curve stretches all the way from negative infinity to positive infinity, so the range is the set of all real numbers.

Correct answer is A

A. $6800 + $1360= $8160 total cost

b.
$68.85 each * 165 bracelets = $11360.25
$11360.25- $8160 total cost = $11278.75 profit

$11278.75 profit/$8160 total cost= 1.38218
1.38218= about 138%

Final answer: 138%
Warning: This answer will vary if you find the percent over cost (not including duty).
