The vector PQ =(-3,2).Given that the point P is (1,4), find the coordinates of the point Q.

Yakvenalex [24]

Answer:

Q = (- 2, 6 )

Step-by-step explanation:

PQ = q - p ← q and p are the position vectors

Add p to both sides

q = PQ + P = (- 3, 2) + (1, 4) = (- 3 + 1, 2 + 4) = (- 2, 6 ), that is

Q = (- 2, 6 )

24. A farmstand collected $350 from sales on Wednesday. This amount was $75

larisa [96]

Answer:

$100

Step-by-step explanation:

Given:

Wednesday sales = $350

If the amount collected from sales on Wednesday was $75 greater than the amount collected from sales on Tuesday, then Tuesday's sales were $75 less than Wednesday's sales:

Tuesday sales = $350 - $75 = $275

If the amount collected from sales on Wednesday was two times as great as the amount collected from sales on Monday, then Monday's sales were half Wednesday's sales:

Monday sales = $350 ÷ 2 = $175

To calculate how much more the farmstand collected from sales on Tuesday than it collected on Monday, subtract the Monday sales from the Tuesday sales:
