Answer:
C. are made of electrons, protons, and neutrons
D. are the smallest unit of matter
Step-by-step explanation:
Answer:
Construct a line from A perpendicular to the x-axis, determine the distance from A to the x-axis along this perpendicular line, find a new point on the other side of the x-axis that is equidistant from the x-axis
Step-by-step explanation:
we know that
The rule of the reflection of a point across the x-axis is equal to
(x,y) -----> (x,-y)
That means ----> The reflected point will be located equidistant from the x-axis
so
Construct a line from A perpendicular to the x-axis
Determine the distance from A to the x-axis along this perpendicular line
Find a new point on the other side of the x-axis that is equidistant from the x-axis
therefore
A(-2,1) --------> A'(-2,-1)
The reflection point is A'
The distance of point A to the x-axis is equal to 1 unit
The distance from point A' to the x-axis is also 1 unit
Pythagorean Theorem:
states a^2 + b^2 = c^2
given triangle:
5^2 + 13^2 = 14^2
25 + 169 = 196
194 = 196 False so it isn't a right triangle
since C^2 (196) is greater than a^2 +b^2 (194)
the triangle would be Obtuse
Well the total would be -5
Answer:
B
Step-by-step explanation:
minimum = 1
first quartile = 12
median = 6
third quartile = 16
maximum = 19
