Answer:

plot a graph and count it

Step-by-step explanation:

midpoint is the middle point of the line. it can be found by dividing the length of the line by 2 then counting inwards by that number.

PLEASE HELP ASAP!!! CORRECT ANSWERS ONLY PLEASE!!!
soldi70 [24.7K]

Answer: D

<u>Step-by-step explanation:</u>

An on-line electronics store must sell at least $5000 worth of computers and printers per day.

  • "at least" means ≥

Each <u>printer costs $350</u> and each <u>computer costs $750</u>.

  • 350p
  • 750c

This equation is: 350p + 750c ≥ 5000

The store can ship a maximum of 20 items per day

  • "maximum" means "no more than" which is ≤

This equation is: c + p ≤ 20

an airplane flies in the path shown by the vector line UV on the graph below. what is the magnitude and direction of line UV? (1
GaryK [48]

The magnitude and direction of line UV is 19.7° South of West for 8.1 miles

<h3>How to find the magnitude of the vector line UV?</h3>

The magnitude of the vector line UV is given by the length of the line UV,

d = √[(x₂ - x₁)² + (y₂ - y₁)²] where

  • (x₁, y₁) = (2, 3) and
  • (x₂, y₂) = (-2, -4)

Substituting the values of the variables intot he equation, we have

d = √[(x₂ - x₁)² + (y₂ - y₁)²]

d = √[(-2 - 2)² + (-4 - 3)²]

d = √[(-4)² + (-7)²]

d = √[4² + 7²]

d = √[16 + 49]

d = √65

d = 8.06 miles

d ≅ 8.1 miles

So, the magnitude of vector line UV is 8.1 miles

<h3>How to find the direction of the vector line UV</h3>

The direction of the vector line UV is given by Ф = tan⁻¹[(y₂ - y₁)/(x₂ - x₁)] where

  • (x₁, y₁) = (2, 3) and
  • (x₂, y₂) = (-2, -4)

Substituting the values of the variables into the equation, we have

Ф = tan⁻¹[(y₂ - y₁)/(x₂ - x₁)]

Ф = tan⁻¹[(-4 - 3)/(-2 - 2)]

Ф = tan⁻¹[(-7)/(-4)]

Ф = tan⁻¹[7/4]

Ф = tan⁻¹[1.75]

Ф = 60.26°

Ф ≅ 60.3°

Its bearing from the north-south line is α = 90° - Ф

= 90° - 60.3°

= 19.7°

So, its direction is 19.7° South of West

So, the magnitude and direction of line UV is 19.7° South of West for 8.1 miles
