Answer:
C. Back 2N
Step-by-step explanation:
Let forward vectors be positive (+) and backward vectors be negative.
Now take the net force of the two vectors.
=> (+18) + (-20)
=> (-2)
=> (-) Negative sign indicates it backwards and magnitude is 2
=> Therefore sum of vectors is back 2N.
There are a total of 60 permutations makeable from those letters 3 at a time.
Answer:
t = - 24
Step-by-step explanation:
Given t varies inversely as a then the equation relating them is
t = 
← k is the constant of variation
To find k use the condition t = 2 when a = - 4
2 = 
( multiply both sides by - 4 )
- 8 = k
t = 
← equation of variation
When a = 
, then
t = 
= - 24
Answer:
4
1.5(x+4) - 3 = 4.5( x-2)-----------------------open brackets on both sides
1.5 x +6 -3= 4.5x- 9.................................collect like terms
3+9 = 4.5 x- 1.5x
12=3x..................................divide by 3 both sides to get x
12/3=x
x=4
