So the first one is 1 square meter of ceiling, and it says 1 square meter of cieling is 10.75. <em>So the first one is just that, 10.75</em>
The second one says 10 square meters, so just multiply 10.75, by 10.
In which case you get <em>107.5.</em> So that's the answer.
Third one, it gives you how many ceiling tiles you have. So you divide the 100 tiles by 10.75, which gives you 9.30232558, which becomes <em>9.3</em>
I'm sure you can figure out the last one.
Step-by-step explanation:
The rule is add 5 to x
6+5=11
n=11
Using the critical point concept, it is found that a = -3 and b = 7.
<h3>What are the critical points of a function?</h3>
- The critical points of a function are the values of x for which:

In this problem, the function is:

Hence, the derivative is:

Then:







Since the critical point is at x = 2, we have that:




Then:

Critical point at (2,3) means that when
, then:

Answer: $35.35
Step-by-step explanation:
Facts
3 items
item 1: 8.95
item 2: 11.49
item 3: 12.75
6.5% sales tax
Step 1: Find the total cost of the items ,before tax
8.95+11.49+12.75= 33.19
Step 2: Apply the sales tax
6.5% of 33.19 = 2.15735 --> approximatley $2.16
Step 3: Add the sales tax amount to the total cost of the items to find the final total cost.
$33.19+$2.16= $35.35
Hence the answer is B
Hope this helps !! :)) And brainliest would be appreciated
