It's a reflection over the y axis because 'a' represents 'x' and if 'a' is negative it flips to the other side leave 'b/y' to remain the same
Answer:
Option D is the Answer
Step-by-step explanation:
Given : Benni wants to divide 48.6 by 0.7.
To find : In order to estimate the quotient, which is the best expression to use?
Solution :
In order to estimate i.e. an approximate calculation we round the numbers,
48.6 as tenth place is > 5 then it round completely
0.7 as tenth place is > 5 then it round completely
So the estimated expression is given by,
Therefore, option D is correct.
Answer:
44°
Step-by-step explanation:
The reference angle is the magnitude of the smallest angle between the terminal ray and the x-axis.
Your angle is one full circle clockwise plus 44° more (-360° -44° = -404°), so makes an angle of -44° with respect to the positive x-axis. The magnitude of that is 44°.
_____
<em>Using a function</em>
The attachment shows a calculator function that can be used to find the reference angle for any angle. (Replace the value -404 with the angle of your choice.)
