A ship's course is set at a heading of 192°, with a speed of 30 knots. A current is flowing from a bearing of 112°, at 14 knots.
telo118 [61]
What you need to do here is a vector addition of the ship's velocity with respect to the water (V1), plus the velocity of the water with respect to land (V2). 
Also remember that:
<span>i = unit vector east </span>
<span>j = unit vector north </span>

<span>V1 = 30 sin 192 i + 30 cos 192 j </span>
<span>V2 = 14 sin 112 i + 14 cos 112 j. </span>
The formula will look like this
<span>V1 + V2 = ?
Now please use the data to put the values into correct places and there you go! Hope this helps</span>

How many times smaller is 2 × 10^9 than 4 × 10^6? A. 20,000 B. 200,000 C. 200 D. 2,000
bagirrra123 [75]
To find this, we have to find a value x such that 2*10^9 * x = 4*10^6. This is so that if we find x, 2*10^9 is x times smaller than 4*10^6. Then, using the multiplicative property of equality, we can divide both sides by 2*10^9 (to separate x) to get 4*10^6/2*10^9=x. Since 4/2=2 and 10^6/10^9=1/10^3 (since for every power of 10, we add 1, so we have 10*10*10*10*10*10/(10^6)*(10^3) and the 10^6’s therefore cross out), our answer is 2/10^3=2/1,000. However, this is clearly not the answer we’re looking for, and even if we find out how many times larger 2*10^9 is than 4*10^6 by switching the denominator and numerator, we end up with 500. Thus, you must have entered something wrong.

Feel free to ask further questions, and good luck!

Answer too a and b plz don't understand at all
Arisa [49]
Greetings!

Arrange the equation in slope y-intercept form to calculate the rate of change (hourly rate):
y=mx+b

Isolate for y:
45x-3y=-30

Add -45x to both sides:
(45x-3y)+(-45x)=(-30)+(-45x)

-3y=-45x-30

Divide both sides by -3:
\frac{-3y}{-3}= \frac{-45x-30}{-3}

The Equation Is:
\boxed{y=15x+10}

The Hourly Rate (Represented by the slope) is: $15
The Signing Bonus (Represented by the y-intercept) is: $10

<em>The Graph for this Equation is attached below:

</em>I hope this helped!
