Answer:

\triangle d=47.69 Knots

Step-by-step explanation:

Distance of Ship A from B d_1=10 West

Speed of Ship A V_a=17 knots West

Speed of Ship A V_b=25 knots North

Generally the equation for Rate of distance change is mathematically given by

\triangle d=\frac{1}{2\sqrt{(17t+10)^2+(25t)^2}}*\triangle t[17t+10^2+25t^2]

\triangle d=\frac{578+340+1250}{2\sqrt{(17t+10)^2+(25t)^2}}

Therefore with

t=>4PM

We substitute

\triangle d=\frac{882(4)+420+648(4)}{2\sqrt(21(4)+10^2)+(18(4))^2}

\triangle d=47.69 Knots

What is the exact circumference of the circle? Circle A with diameter 60 feet. 10π feet 20π feet 40π feet 60π feet
Gelneren [198K]
The circumference of a circle is 2•3.14(Pi)•R(radius) or 3.14(Pi)•D(diamater).
Since we have our diameter, 60, we need to multiply it by Pi.
60Pi is your answer.

I hope this helps!

What is the endpoint formula given midpoint?
zysi [14]

Answer:

  B = 2M -A

Step-by-step explanation:

For given endpoint A and midpoint M, the other endpoint B can be found using the definition of the midpoint:

  M = (A+B)/2

  2M = A+B . . . . . multiply by 2

  2M-A = B . . . . . subtract A

The second endpoint can be found by subtracting the given endpoint from twice the midpoint:

  B = 2M -A
