A. To show how precise your measurements were
Explanation:
It is important to use the correct number of significant digits when reporting the results of an experiment because they show how precise measurement are.
- Precision is the ability to reproduce a particular set of results in an experiment.
- Every instrument have their precision level.
- The precision levels shows to what extent the values obtained can be trusted..
- Significant figures are not only important in recording measurements, they are also needed for calculations in science.

In order to find out if the exponential function represents a growth or a decay, let's look at the number that is base to the exponent x.
If the number is greater than 1, so the function represents a growth, and if the number is less than 1, the function represents a decay.
Since the number is 1.075, the function represents a growth.
To find the % increase, first let's convert the number to percentage, and then subtract 100%:

So the percent increase is 7.5%.
You have learned your lesson well, Suhay. Your statement is correct.
The light rays from the fish BEND when they flow out of the water into the air. But our primitive brain still believes that the light rays flow STRAIGHT from the fish. The result is that the fish does not APPEAR to be at that place where it really is.
Answer:
Part a)
P = 1200 Watt
Part b)
P = 480 W
Part c)

Explanation:
Part a)
Power consumed by blow dryer is given as

here supply voltage is given as

current rating of blow dryer is given as



Part b)
Power consumed by vacuum cleaner is given as

here supply voltage is given as

current rating of vacuum cleaner is given as



Part c)
Energy consumed in a given interval of time is given as

now we have to find the ratio of energy consumed in time interval of 11 minutes
so we have

now we have
