B) (-4, -4)
When moving to the right you are moving to a more POSITIVE region on the x-axis; meaning, the y-value (vertical axis) does not get affected unless you’re moving up or down.
Remember: (-6, -4)
X = -6
Y = -4
If you move 2 units to the right (x-axis) you go from -6 + 2 which equals -4. And again, you’re not moving up and down so your
y-value stays the same and your new coordinates are (-4, -4)
Answer: B) 684m
Step-by-step explanation:
From 9 to 27 is a 3 times increase, from 27 to 108 is a 4 times increase. So following the pattern, we can determine that it will increase 5 times, and fall another 540m in second 4. Then, we simply add all the numbers together to get the answer!
The answer is in the attached image
Answer:
<h2>Side YZ is 8 units long.</h2>
Step-by-step explanation:
We can deduct form the graph that segment WO is a radius of the circle and XY is its diameters.
By given, we know that 
, which means 
, by radius definition.
An important characteristic of tangents about circles is that the tangent is always is perpendicular to the radius, that means 
and 
is a right triangle, that means we can use Pythagorean's Theorem to find the side YZ.
Where 
is the hypothenuse and 
, 
are legs of the triangle.
Replacing all given values, we have
However, by sum of segments, we have
, where 
and 
Therefore, side YZ is 8 units long.
