Answer: p x (3q - 5 - 2pq)
The sum of two vectors is (- 0.5, 10.1)
<u>Explanation:</u>
To add two vectors, add the corresponding components.
Let u =⟨u1,u2⟩ and v =⟨v1,v2⟩ be two vectors.
Then, the sum of u and v is the vector
u +v =⟨u1+v1, u2+v2⟩
(b)
Two vectors = ( 3, 4 )
angle 2π/3 = 120°
In x axis, the vector is = 7 cos 120°

In y axis, the vector is = 7 sin 120°
= 7 X 0.866
= 6.062
The second vectors are ( -3.5, 6.062)
Sum of two vectors = [( 3 + (-3.5) ), (4 + 6.062)]
= (- 0.5, 10.1)

Answer:
$63.84
Step-by-step explanation:
A book shop offers a discount on a book = 24%
The original price of the book = $84.00
we have to calculate 24% of $84 and then subtract the discount price in the original price.
Sam purchases this book = 84 -(24% × 84)
= 84 - ( 0.24 × 84)
= 84 - 20.16
= $63.84
Sam has to pay $63.84 if he purchases book.
