Perpendicular means the slopes are opposite inverse of each other
If line a is slope 2, the perpendicular line to Line a would have a slope - 1/2
Difference in y over difference in x gives slope. If they are opposite inverse values the lines are perpendicular. ( in this case the answer is true.)
Answer:
5units
Step-by-step explanation:
The triangle inscribed in the circle is a right angled triangle with angle C being 90°.
The diameter of the circle AB is the hypotenuse of the triangle.
Before we can get the radius, we need to get the diameter AB using Pythagoras theorem.
|AB|² = |AC|²+|BC|²
|AB|² = 6²+8²
|AB|² = 36+64
|AB|² = 100
|AB| = √100
|AB| = 10
Diameter of the circle = 10units
Radius = diameter/2 = |AB|/2
Radius = 10/2
Radius = 5units
Answer: x + 3x = 11
Step-by-step explanation:
Two cities A and B
Both cities receive 11 inches of rainfall in total
Amount of Rainfall in inches received by city A = x
Amount of Rainfall in inches received by city B = 3x
Therefore given the details above, total rainfall is best expressed using the equation ;
Rainfall in city A + Rainfall in city B = 11 inches
x + 3x = 11
2.38 I think that’s it might be wrong tho
