Let the origin of the coordinate system be the position of ship B at noon. Then the distance between the ships as a function of t (in hours) is
.. d = √((30 +23t)² +(17t)²)
.. = √(818t² +1380t +900)
The rate of change of distance with respect to time is
.. d' = (1/2)(2*818*t +1380)/√(818t² +1380t +900)
.. = (818t +690)/√(818t² +1380t +900)
At t=4, this is
.. d' = (818*4 +690)/√(818*16 +1380*4 +900)
.. = 3962/√19508
.. ≈ 28.37 . . . . . knots
The distance between the ships is increasing at about 28.37 knots at 4 pm.
To <u>convert an integer to a fraction</u> you must choose an expression that does not alter the numerical value. You can do this with multiples of the number, for example, for 100:
100/1 = 200/2 = 300/3 = 400/4 = 100
- The numerical value is not altered and the result will always be 100
Another example, for 500:
500 = 500/1 = 1000/2 = 1500/3 = 2000/4
<h2>{ Pisces04 }</h2>
For this case we must write as a percentage the following expression:

Dividing we have to:

Now we multiply by 100%. So:

We run the decimal two spaces to the right, finally we have:
84%
Answer:
84%
Answer: There is no difference as the difference equals 0.
Step-by-step explanation:
Parking lot a is 1/4 Mile Long and 3/16 miles wide
Area = length × width
= 1/4 × 3/16
= 3/64
Parking lot B is 3/8 mile long and 1/8 mile wide
Area = length × width
= 3/8 × 1/8
= 3/64
Difference between the areas of parking lot A and B will be:
3/64 - 3/64
= 0
There is no difference.
