Answer:
-1/8
Step-by-step explanation:
When slopes are perpendicular that means it's completely opposite.
The opposite of 8 is 1/8
But 8 is positive that means we have to make the pereldicular slope negative
Therefore your answer is -1/8

Answer:
2√5
Step-by-step explanation:
Using the formula for calculating resultant
R = √Fx + Fy
\sum Fx = -2sin 45 + 4 cos 45
\sum Fx = 2cos45
\sum Fx = 2(1/√2)
\sum Fx = 2/√2
Similarly;
\sum Fy = 2 cos 45 + 4 sin45
\sum Fx = 2(1/√2) + 4(1/√2)
\sum Fx = 6/√2
Magnitude = √(2/√2)²+6/√2)²
Magnitude = √4/2 + 36/2
Magnitude = √2+18
Magnitude = √20
Magnitude = 2√5
Hence the magnitude of their sum is 2√5
Hey there!
Firstly, we are going to divide by

on each of your sides because it paired off with a variable
Here's what I meant!

We would have to cancel out the:

because it gives us
