Answer:
10 hours
Step-by-step explanation:
Given:
Average speed of submarine = 10 mph
Speed of carrier in the opposite direction = 20 mph
Distance between the submarine and carrier = 300 mi
To find:
The time taken so that the distance between them is 300 mi ?
Solution:
The relative speed when they are traveling in opposite direction = 10+20 = 30 mph
Formula:


So, the answer is <em>10 hours</em>.
Answer:
Step-by-step explanation:
<h3>Given</h3>
- f(x) =

<h3>To find </h3>
<h3>Solution</h3>
<u>Change f(x) → x, and x → y, and solve for y:</u>
- x =

- x² = 7y - 21
- 7y = x² + 21
- y = 1/7x² + 3
<u>y = f⁻¹(x)</u>
