You are trying to decide whether to use Uber or Lyft during a vacation. Uber charges $3 to pick up plus an additional $0.25 for

each mile driven. Lyft does not charge to pick up but they have a rate of $0.75 for each mile driven.
Let x = the number of miles traveled and y = the total cost for the trip.

Will the cost of the two companies ever be the same? If so, at how many miles and what is that cost? If not, explain your reasoning. Show all work that leads to your answer.

The length of a rectangle is 8 inches longer than the width. If the area is 295 square inches, find the
sladkih [1.3K]

Answer:

L=21.6in and w=13.6

Step-by-step explanation:

If the length is 8 inches longer than its width, we can write the width as "w" and the length as the width w+ 8

Area is (width)(Length) = (width)(width+8)

W

----------

| |

| |

| | L = w+8

| |

| |

-----------

A = (w+8)(w)

A = w2 + 8w = 295.

(Problem states that area is 295 sq in)

Need to solve this quadratic equation

w2 +8y - 295 = 0

Factor:

(w - 13.64) (w + 21.64) = 0

So

w - 13.64 = 0. or. w + 21.64= 0

Solve these and get

w = 13.64. or. w = -21.64

Only one that makes sense in real life is the poitive one.

So the dimensions are

Width = 13.64 inches

Length = 21.64 inches

Convert the polar coordinates (120.2, 119°) into rectangular coordinates. Round the rectangular coordinates to the nearest hundr
Alchen [17]
The conversion is
  x = magnitude × cos(angle)
  y = magnitude × sin(angle)
or
  (x, y) = 120.2(cos(119°), sin(119°)) ≈ (-58.27, 105.13)

Solve the right triangle. Round to the nearest degree and nearest tenth of a unit. What is the right angleV?
N76 [4]

Answer:

  m∠V ≈ 61°

Step-by-step explanation:

The hypotenuse and the side opposite the angle of interest are given. The relevant trig relation is ...

  Sin = Opposite/Hypotenuse

  sin(V) = XW/XV = 7/8

The inverse sine function is used to find the angle:

  V = arcsin(7/8) ≈ 61°
