Answer:
6
Step-by-step explanation:
We need to evaluate :-
Here the
is the sum operator . And here we need to find the sum from n = 1 to n = 4 . We can write it as ,
Now we know that for odd powers of -1 , we get -1 and for even powers we get 1 . Therefore ,
Now add the terms inside the brackets and then multiply it with the number outside the bracket . We will get ,
<u>Hence</u><u> the</u><u> </u><u>required</u><u> answer</u><u> is</u><u> </u><u>6</u><u>.</u>
Step-by-step explanation:
C≈62.83m
Using the formulas
C=2πr
d=2r
Solving forC
C=πd=π·20≈62.83185m
Answer:
See below
Step-by-step explanation:
So basically the product is the result of mulyplying ---> factor × factor = product. You need to replace the values given so basically
8 ×2/5(0.40) =3.2 which is between 0 and 8, making the first statement true. Hopefully, this gives you an idea on how to answer the rest!!
Since it is positive power, the answer is -1 so it is B.
