Answer:
The answer to your question is dAC = 10 units
Step-by-step explanation:
Data
From the graph, take the coordinates of the points A and C.
A (3, - 1)
C (-5, 5)
Process
Use the formula of the distance between two points to find the length
d =
x1 = 3 y1 = -1
x2 = -5 y2 = 5
Substitution
dAC =
Simplification
dAC =
dAC =
dAC =
dAC = 10 units
b. Both forces act in the same direction, so add their magnitudes.
Net force: 2 N + 4 N = 6 N to the right
Change in motion: the box will move to the right.
c. The forces act in opposite directions, so subtract the magnitudes. The motion is in the direction of the force with greater magnitude.
Net force: 10 N - 8 N = 2 N to the right
Change in motion: the box will move to the right.
Using factorization method;
x²+13x+40=0
x²+13+40
Find two numbers that you can add together to give the co-efficient of variable x. (I.e 13 for this question). Also, you'll find two numbers that you can multiply with each other to give you the whole number as an answer. (I.e 40 in this question). The two numbers must be the same (i.e the two numbers that will be added to give the co-efficient of x and the two numbers that will be multiplied to give the whole number must be the same two).
The two numbers are +5 and +8
The equation will therefore be = x²+5x+8x+40
You'll then factorize (I.e use a common factor of both values to bracket them)
x(x+5)+8(x+5)
(x+8)(x+5)
x is therefore (x+8=0) or (x+5=0)
x=(x=0-8) or (x=0-5)
x= -8 or x= -5
