Assuming this is a triangle then the answer would be 10 but that's not an option. If you gave me more information or confirmed what shape I'm dealing with I may be able to help you.
Answer:
16/6 = 2 4/6 = 2 2/3
Step-by-step explanation:
the answer is two and two thirds assuming that this is a fraction :)
Answer:
The distance is minimized 22 minutes after 3:00 pm.
Step-by-step explanation:
Let t is the time for the 2 boats after 3:00 pm, we have the distance of:
- Boat 1: 20t
- Boat 2: 15t and its distance to the dock is given by (15-15t)
The paths of the boats form a right triangle, in which the hypotenuse (also the distance between the two boats) is:
D = (20t)² + (15 - 15t)²
<=> dD/dt = -2(15² )( 1-t ) +2 × 20² × t
<=> dD/dt = 2 (15² + 20²) × t -2 ( 15 )² = 0
<=> t = 2 ( 15 )² : 2 (15² + 20²)
<=> t = 0.36 hours = 0.36 × 60 = 21.6 minutes ≈ 22 minutes
Therefore, the distance is minimized 22 minutes after 3:00 pm.
If the line that passes through (5,-2) is parallel, then the slope will be the same, but 'b' aka the y-intercept will change. In order to do that you plug in the data point (5,-2) for x and y and solve for b. After you plug in the data point the equation would look like this:
-2 = 7(5) - b
After you solve for b, you would get b = 37. So the final equation would be y = 7x + 37.
