Let i = sqrt(-1) which is the conventional notation to set up an imaginary number
The idea is to break up the radicand, aka stuff under the square root, to simplify
sqrt(-8) = sqrt(-1*4*2)
sqrt(-8) = sqrt(-1)*sqrt(4)*sqrt(2)
sqrt(-8) = i*2*sqrt(2)
sqrt(-8) = 2i*sqrt(2)
<h3>Answer is choice A</h3>
Answer:
216mx meters
Step-by-step explanation:
m is in minutes so convert it in hours = 60m hrs
Speed is in metres per second, convert it in kilometers per hour= 18x/5
Now we’ve time and speed, put it in the formula
Distance = speed x time
= 18x/5 x 60m
= 216mx meters
Hope it helps
Answer:
b) all of the cupcakes in the bakery
Explanation:
in statistics, the population is a group of people/things that are in the same category for collecting data. c) and d) are thus wrong since no data is collected about the other goods or the employees, while a) is wrong because that is just a sample (which helps to test for a large population) and not the actual population.
i hope this helps! :D
I am pretty sure it is B.
