Answer A. 17
Step-by-step explanation: The cost, in dollars is increasing by $1.05 by 1’s. To get from 1.05 to 2.10 is 1.05. So to find the Gallons of Gas, you would keep adding 1.05 until you get 17.85 or you can multiply the numbers in the answer choice by 1.05 to get your answer.
Answer:
Step-by-step explanation:
Use the Law of Cosines:
a² = b² + c² - 2ab·cos A
Substituting the given values, we obtain:
a² = (10)² + (7)² - 2(10)(7)·cos 52°
= 100 + 49 - 140·0.6157
= 149 - 86.1926
= 62.81
Taking the square root of both sides yields:
a = 7.925, or (to the nearest degree) 8
Answer:
- 627 miles north
- 747 miles east
Step-by-step explanation:
Bearing angles are measured east of north, so in (N, E) coordinates, the final position of the plane is ...
(1.5 h)(650 mi/h)(cos(50°), sin(50°)) = (975cos(50°), 975sin(50°)) mi
= (626.72, 746.89) mi
The plane will be 627 miles north and 747 miles east of its point of departure.
