A Woman Leaves Home And Walks 3 Mi. West, And Then 2 Mi. South. What Is The Magnitude Of Her Displacement, and what direction mu
mojhsa [17]

Answer: 4 Mi Northeast

Step-by-step explanation:

  • west points left on a compass, and x points left on a graph so the value becomes x ⇒ ( 3x )
  • south points down on a compass, and y points down on a graph so the value becomes y ⇒ ( 2y )

Equation: V=3x +2 y

Solving Steps:

1. take the sum of the square of each vector component

3^2 + 2^2 = 9 + 4 = 13

2. take the square root of the result from from the last step

\sqrt{13}=3.60555127546

3. round to nearest whole number as told in your question

60555127546 ⇒ 4

4. find direction to go with number

- opposite of west is east

- opposite of south is north

direction is northeast

========================

ans = 4 Mi Northeast

A circle has an area of 50 square meters. Which answer is closest to the measure of its diameter?
gregori [183]
Area of a circle is computed by multiplying pi to the square of the circle's radius.

A = πr²
50m² = 3.14 r²
50m²/3.14 = r²
r² = 15.92m²
r = √15.92m²
r = 3.99m

Diameter is computed by multiplying the radius twice.
d = 2r
d = 2(3.99m)
d = 7.98m or rounded up to 8 m

ANSWER ASAP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
aev [14]

Answer:

Sequence 1: Translate 5 units to the right, and 5 units down

Sequence 2: Reflect across the origin, translate 1 unit down, 1 unit to the right

Step-by-step explanation:

Chose 1 point to focus in, such as (-1, 1)

Move that point 5 units to the right, and 5 units down. See how it matches up with the same corner of the red square?

Now, use that same point, and change the signs of both the x and y, this is to reflect across the origin. (In reality, you are just reflecting across the x and y axis)

So you originally have: (-1,1) -> (1, -1)

Now move this point one unit to the right, and 1 unit to the left.

It may seem that you made it touch the wring corner, but do the same thing with another corner's points. They all flipped!
