1. For the three-part question that follows, provide your answer to each question in the given workspace. Identify
1 answer:
Answer: a) 6 b) 11.53 c) the smallest number of significant digits is 4
<u>Step-by-step explanation:</u>
a)
Complete the subtraction and addition (you can do this manually by lining up the decimal ... or... using a calculator)
2.784 - 3.00079 + 10.671 + 1.0798 = 11.5340
→ there are 6 digits in the answer
b & c)
2.784 has 4 significant digits
3.00079 has 6 significant digits
10.671 has 5 significant digits
1.0798 has 5 significant digits
→ the smallest number of significant digits is 4 so round the answer from part a to 4 significant digits:

Answer:
Period ⇒ 40
Amplitude ⇒ 12
Mid-line ⇒ 32
Step-by-step explanation:
The table is counting by 4's and the period is the amount of space between 2 peaks. In this scenario, we can find the peaks by looking for two of the same highest value (44). We can see that x=40 has a value of 44 while the other is actually not shown because it would be located at x=0. Therefore the period is 40
<u />
The amplitude can be found by using the following:
Our maximum is 44 and our minimum is 20.
The amplitude is 12
The amplitude is the distance from the peak to the mid-line. To find the mid-line, we can either subtract our amplitude from our maximum value (44) or add our amplitude to our minimum value (20)
44 - 12 = 32
20 + 12 = 32
Therefore our mid-line is y = 32
~Hope this helps!~
