Answer:
Step-by-step explanation:
We are given the following in the question:
Let the equation:
be the linear equation that represent temperature at an elevation x.
Temperature at 6000-foot level = 76 f
Temperature at 12000-foot level = 49 f
Solving the two equation, we get,
Thus, we can write the linear equation as:
Answer:
- <u>14.4 mile</u>²
Explanation:
1. By driving 6 miles each, the cars will be 6 miles + 6 miles = 12 miles appart.
2. When one car stops and the other car makes a 90° left-hand turn and drive 8 miles, you can model the situation with a right triangle, where one leg is 12 miles, the other leg is 8 miles, and the hypotenuse is the distance that separates the cars.
Hence, you must use Pythagoras to find that distance.
3. Pythagoras
- hypotenuse² = leg₁² + leg₂²
- hypotenuse = (12 mile)² + (8 mile)² = 144 mile² + 64 mile² = 208 mile²
, which is rounded to the neartest tenth of a mile.
