Given that P = (-5, 5) and Q = (-13, 10), find the component form and magnitude of 2 vector PQ.
tester [8842]
Define the unit vectors along the x and y axes as \hat{i}, \, \hat{j} correspondingly.

Consequently, the vector from P to Q is
\vec{PQ} = (-13+5)\hat{i} + (10-5)\hat{j} = -8\hat{i} + 5\hat{j}
In terms of components, vector PQ is represented as (-8,5).

The magnitude of vector PQ can be calculated as
√[(-8)² + 5²] = √(89) = 9.434

Answer:
Thus, vector PQ is (-8, 5), and its magnitude equals √89 (or 9.434).

lawyer [9240]

Answer:

Shane must have gathered a minimum of 911 cans.

Step-by-step explanation:

Let S represent the number of cans Shane collected.

Since Abha collected 178 more cans, her total is S + 178.

The combined total should be at least 2000:

S + (S + 178) ≥ 2000

2S + 178 ≥ 2000

2S ≥ 2000 - 178

2S ≥ 1822

S ≥ 911

Therefore, Shane must have collected at least 911 cans.

What does distributions from owners int non adr mean?
AnnZ [9099]
Distributions from owners refer to payments that business owners take out from profits the firm earns, commonly issued as dividends. An ADR, or American Depositary Receipt, is a type of stock bought and sold within the U.S. market that represents a specific number of shares in a foreign company. Therefore, the owner’s payments do not originate from the ADR shares.

Inessa [9000]

Answer:

tan−1(StartFraction 6.9 Over 9.8 EndFraction)

Step-by-step explanation:

tan−1(StartFraction 6.9 Over 9.8 EndFraction)

The tangent is defined as opposite over adjacent, thus 9.8/6.9

The inverse tangent operates as 1 / tan and equals 1 / (9.8 / 6.9) = 6.9 / 9.8
