First find slope.
slope=change in y/change in x (y2-y1/x2-x1)
slope=4-3/-2-(-4)=1/2
Now we need to find the x intercept.
y=mx+b
3=1/2(-4)+b
b=5
So the equation is y=1/2x+5.
12
Square of 13 equals 169
Square of 5 equals 25
169-25= 144
144 square root equals 12
Answer:
7
Step-by-step explanation:
7x4=28
6x4=24
So it cant be 6 or anything less
Answer:
a. When vector is added to vector , the resultant is vector such that its magnitude and direction is proportional to the resultant magnitude and direction of the component vectors.
b. ∅ = (Rx/Ry)
Step-by-step explanation:
Vectors are used to express physical quantities with magnitude and direction. Vectors can be added by the parallelogram method or the triangular method of addition. the magnitude and direction of the resultant vector is usually proportional to the magnitude and direction of the component vectors.
The direction of the angle is found as
tan∅ = Rx/Ry
∅ = (Rx/Ry)
