Magnitude of force= |F|= 5 lb
In the direction of vector,let say M=5i-3j
As, we know that vector consists of magnitude and direction( unit vector)
F=|F| M(unit vector).........1
In order to find the unit vector, divide the vector M by its magnitude.
M(unit vector)=(5i-3j)/√34
Now, the eq. 1 becomes
F=5(5i-3j)/√34
F=(25i-15j)/√34
As, the object moves from point let say P=0i+6j to Q=7i-4j
so,
PQ=Q-P
=(7-0)i+(-4-6)j
=7i - 10j
So,
W= F.PQ
=((25i-15j)/√34).(7i-10j)
=(7*25/√34)+(-10*-15/√34)
=55.7 lb*ft
=56 lb*ft
Option C is correct
Answer:
cones cylinder sphere
Step-by-step explanation:
P = 300 $; r = 0.06; t = 20; n = 1
A = P ( 1 + r/n)^n*t
= 300 ( 1 + 0.06) ²⁰
= 300 ( 1.06) ²⁰
= 962.14
Answer: 150%
Step-by-step explanation:
A store buys a television for $120.
The store then sells the television for $300.
The makeup is the amount they increased the cost price by to get to the selling price.
= 300 - 120
= $180
In percentage terms it is:
= 180/120 * 100%
= 150%
