From the given problem, I gather that there are only two groups of forces. These are:
13 lb, 35 lb, resultant force 30 lb
20 lb, 15 lb, resultant force 25 lb
We use the pythagorean theorem to determine if the three forces are grouped correctly, such that the resultant force is the hypotenuse.
Resultant Force = √(a² + b²)
So, for the first group,
30 ? √(13² + 35²)
30 ≠ 37.33
Thus, the first group does not pull at right angles to each other.
For the second group,
25 ? √(20² + 15²)
25 = 25
Thus, the second group does pull at right angles to each other.
a title. Hope this helped could I possibly get brainliest?
Answer:
Point B would be at 5.
Step-by-step explanation:
Given segment AC in which point A is at -3 and point C at 7, representing this on the number line shows that there are 10 points from A to C.
-3 -2 -1 0 1 2 3 4 5 6 7
A C
Since the segment AC is to be divided into a ratio 4:1, then moving from point A to B (at point 5) would be the required point. Therefore, point B that would divide segment AC in ratio 4:1 is at 5.
Thus, A is at -3, B is at 5, and C is at 7.
Answer:
You are transposing so
and
Step-by-step explanation:
Basically in transposing, you use reverse operations to get rid off attached or unnecessary terms till you get what you want on one side of the equal sign
