Los angeles is 1,744 miles from chicago; chicago is 714 miles from new york; and new york is 2,451 miles from los angeles. The t
klemol [59]

Answer:

170°

Step-by-step explanation:

Let a be the distance from Los Angeles to Chicago = 1744 miles, b be the distance from Chicago to New York = 714 miles and c be the distance from New York to Los Angeles = 2451 miles.

A is the angle opposite to side a, B is the angle opposite to side b and C is the angle opposite to side c.

Therefore the angle at Chicago is  C.

From cosine rule:

c² = a² + b² - 2ab × cos (C)

2ab × cos (C) = a² + b² - c²

cos (C) = (a² + b² - c²) / 2ab

Substituting:

cos (C) = (1744² + 714² - 2451²) / 2×1744×741

cos (C) = -0.986

C = cos⁻¹ (- 0.986) = 170°

kaheart [24]

Answer:

positive slope

(0,3)

slope = 2

Step-by-step explanation:

  • Slope of the given line is positive
  • If the line is sloping upward from left to right, so the slope is positive (+).

or if the angle made by the line to the x axis is < 90 it's slope is positive.

  • y-intercept of the line is (0,3)
  • The y intercept is the point where the line crosses the y axis. At this point x = 0.
  • slope of the line is 2
  • slope = (y2 - y1) / (x2 - x1)

    lines passing through points (1,5) (0,3)

    slope = (3 - 5) / (0 - 1)

              = -2 / -1 = 2

If the car spends 2.5 hours going 35 miles per hour on the trip, how long does it spend going 55 miles per hour?
aleksklad [387]
Simple problem, just use a proportion:
2.5/35 = X/55
Now cross multiply:
137.5 = 35X
X = 3.928
