As a decimal, you would have to divide 275 by 100
275/100 = 2.75
The submarine would be 146
By using a tens number as you refer to a multiple of ten. As a multiple of ten you can just add it to another number easier than a ones number
Given:

To find:
The interval(s) on which the given function is positive.
Solution:
We have,





For zeroes, 


-1 and 5 divide the number line in three parts
.
Interval Selected Value
Sign
-2
+
0

6
+
So, the function is positive for interval
and
.
We can say that the function is positive for interval x < -1 and x > 5.
Therefore, the correct option is B.
Answer:
A
Step-by-step explanation:
5/(1-√3)=5*(1+√3)/(1-√3)(1+√3)= (5+5√3)/(1-3)= -(5+5√3)/2
Choice A is correct one
