(-3,-3) and at (0,6)
Step-by-step explanation:
The solution to the system of equations is where the graphs intersect
The graphs intersect at (-3,-3) and at (0,6)
Answer:
there are 3 roots at x=+-1, +3, +4
Step-by-step explanation:
Given:
To find:
The quadrant of the terminal side of 
and find the value of 
.
Solution:
We know that,
In Quadrant I, all trigonometric ratios are positive.
In Quadrant II: Only sin and cosec are positive.
In Quadrant III: Only tan and cot are positive.
In Quadrant IV: Only cos and sec are positive.
It is given that,
Here cos is positive and sine is negative. So, 
must be lies in Quadrant IV.
We know that,
It is only negative because lies in Quadrant IV. So,
After substituting , we get
Therefore, the correct option is B.
Answer:
18%
Step-by-step explanation:
413-350=63%
(63/350)*100=18%
Answer: B
Step-by-step explanation:
After adding the new data set to the median, we re-arrange in ascending order
23, 26, 26, 29, 30, 33, 40
Median is the midpoint value in the data set, therefore, median is still 29.
I hope this helps.
