Answer:

Answer:

50.2

Step-by-step explanation:

$ut = \sqrt{ {6}^{2} + {5}^{2} } \\ \sqrt{36 + 25} \\ \sqrt{61 } \\ using \: cosine \: rule \\ cos \: u = \frac{ {5}^{2} + 61 - 36 }{2 \times 5 \times \sqrt{61} } \\ \\ = \frac{25 + 61 - 36}{78} \\ \\ = \frac{50}{78 } \\ \cos \: u = 0.64 \\ \m∠U.: = 50.2$

Which of the following three vectors has the greatest magnitude: v + (−w), w − v, or

makvit [3.9K]

Answer:

All have same magnitude.

Step-by-step explanation:

Given that

Vector 1 = V+ (-W) = V - W

So the magnitude of vector 1, R₁

$R_1=\sqrt{(V-W)^2}$

R₁ = V -W

For vector 2

Vector 2 = W - V = W - V

So the magnitude of vector 2, R₂

$R_2=\sqrt{(W-V)^2}$

R₂ = V - W

For vector 3

Vector 3 = (-V) - (-W) = - V + W = W - V

So the magnitude of vector 3,

$R_3=\sqrt{(W-V)^2}$

R₃ = W -V

So all have same magnitude.

For part 2, you would use 3 thousands, as that is the biggest amount possible so far. The, you would use 1 ten [instead of 16 ones] and then 6 ones bacuse that is the smallest amount.

A store had 3 packs of paper $0.93. How much would it cost if you were to buy 4 packs?

sesenic [268]

Hey you!

If I understood your question correctly, here's your answer:

0.93/3 = 0.31

0.31 × 4 = 1.24

So, it would cost $1.24 for 4 packs.
