(1 pt) At noon, ship A is 50 nautical miles due west of ship B. Ship A is sailing west at 15 knots and ship B is sailing north at 21 knots. How fast (in knots) is the distance between the ships changing at 4 PM? (Note: 1 knot is a speed of 1 nautical mile...

Consider the function f(x) whose second derivative is f(x)=9x+6sin(x). If f(0)=4 and f(0)=3, what is f(x)? Please do not include the constant (+C) in your answer.

Evaluate the following sum: 10 E (–1)^n–1(1n^2–9n–3) n=4

A thin rod 2.4 m long with a mass of 3.45 kg is rotated counterclockwise about an axis through its midpoint. It completes 3.9 revolutions every second. What is the magnitude of its angular momentum?

A pressure difference of 1.5x10^3 Pa draws water from a well. The water emerges from the pump with a speed of 17.0 m/s. What is the depth of the well?

thanks for helping me but it keeps telling me the answer 18.29 knots is wrong

oh im sorry it is f(0)=4 and f'(0)=3

and it's f''(x)=9x+6sin(x) sorry

i got the answer 1.5x^3-6sinx+9x+4

i got 5

hghgh

the answer to (a) is T2

its B B A

its gas no cap.

Cheez itz has big brain

the science guy

bro its obv 69.420

thank you izzy!!
