Step-by-step explanation:
Answer:
(c) will be perpendicular to the line y = 3x+2
Step-by-step explanation:
We have given the the equation of line as y = 3x+2
We know the equation of line as y = mx+c , here m is slope and c is intercept
On comparing with standard equation of line m = 3
We know that slope of perpendicular line is
So the slope of the line which is perpendicular to y = 3x+2 will be
Now (a) Line is given as its slope is so it will be not perpendicular
(b) Line is given as its slope is so it will be not perpendicular
(c) Line is given as its slope is so it will be perpendicular to the line y = 3x+2
(d) Line is given as its slope is 3 so it will not perpendicular to the line y = 3x+2
Answer:
Geometric mean is the nth root of the product of n numbers
For two numbers it's the square root
for three numbers it's the cube root
for 4 numbers it's the fourth root
etc.
--------------------------
5 and 20
m = √(5 * 20) =
m = √100
m = 10
3 and 12
m = √(3 * 12)
m = √36
m = 6
do the rest the same way
