(10,27)
Step-by-step explanation:
Hope this helps!!! :)
Question #1:
a)
(4, 2)
Both of these are positive, and when x and y are both positive they're both in Quadrant 1.
b)
(x + 1, y - 5)
Add 1 to 'x', subtract 5 from 'y':
(4 + 1, 2 - 5)
(5, -3)
x is positive and y is negative, that means this will be in Quadrant 4.
c)
Reflection Across y-axis:
(-x, y)
Multiply -1 to 'x':
(5 * -1, -3)
(-5, -3)
Both of these are negative, if both x and y are negative it's located in Quadrant 3.
Question #2:
No, that can't tessellate a plane. We can't cover up space so there are no overlaps or gaps.
Answer:
<em>d)</em> times
Step-by-step explanation:
<u>Scientific Notation</u>
We are given two quantities and we must find the ratio between them and use scientific notation.
The diameter of a pearl is about
Converting to meters, we divide by 100
The diameter of an atom is about
The ratio between both diameters is:
Answer: d) times
