Answer:
B. y=sin(x) and y=-1/2
Step-by-step explanation:
We have been given the following trigonometric inequality;
2sin(x)=>-1
The above inequality can be re-written as;
sin(x)=>-1/2
after dividing both sides by 2.
We can then formulate two separate equations, one containing the expression on the right hand side and the other containing the expression on the left hand side;
From the left hand side we form the following equation;
y = sin(x)
From the right hand side we form the following equation;
y = -1/2
Therefore, the above two equations can be graphed to help solve the given trigonometric inequality
Let the length of one of the shorter pieces be
. Then, we know that two of the pieces are that length, and the third piece is
. Since these are all pieces of a rope, all we need to do to figure out the lengths is add all those together, solve for
, and then plug that back in to the desired lengths:
Shorter pieces:
Longer piece:
20 edges
F=12, V=10
V -E+F=2
10-E+12=2
-E+22=2
-E=-20
E=20
Answer:
7
Step-by-step explanation:
It is a pattern where you add 3 each time
The lower quartile is the mean of the lower half of the data set, not incuding the median value. In this case, the lower half is 5, 8, 10, 20 and the median is 9.
