Question2 Explain what a line of symmetry is.
2 answers:
A line of symmetry is a line that divides a figure into two parts such that each part is the mirror image of the other. In other words, if we flip one side of the figure over the line of symmetry, it should match up <em>exactly</em> with the other side.
Let's look at a 2 examples.
In the first image provided, notice that if we flip the left side of the figure over the right side, the two sides will not match up so this is not a line of symmetry.
In the second image, if we flip the left side of the line on to the right side, it matches up exactly so it's a line of symmetry.

Answer:
11.57 units east, 13.79 units upwards
11.57i + 13.79j
Step-by-step explanation:
V = 18 units at an angle of 50° to the positive x-axis
In component Form, this is how each component is calculated
a = 18cos50° = 11.57 units east
b = 18sin50° = 13.79 units upwards

In vector component form ai + bj = 11.57i + 13.79j
Answer:
right-handed gloves and
left-handed gloves were sold.
Step-by-step explanation:
Given: In one month, gloves were sold for a total revenue of
.
right-handed gloves cost and left-handed gloves cost
.
To find: How much of each type of gloves did they sell?
Solution: Let they sell right-handed gloves, and
left-handed gloves.
Now, cost of each right-handed gloves
cost of each left-handed gloves
Total revenue
So, we get
Also, in a month gloves were sold.
So, we get
Now, from we get,
.
Putting in equation
, we get
Now, putting in equation
, we get
Hence, right-handed gloves and
left-handed gloves were sold.
