Same. You should use Desmos online graphing calculator if you have anymore problems like this. You just put it into the calculator and it graphs the line. In this case, the line must be perpendicular to the line CD, basically a horizontal version of the line. I put all of these into Desmos and the one that is perpendicular is -0.5x + 5.5. Hope this will help you in the future!
Answer: The sailboat is at a distance of 15 km from the port.
Step-by-step explanation: Given that a sail boat leaves port and sails 12 kilometers west and then 9 kilometers north.
We are to find the distance between the sailboat from the port in kilometers.
Since the directions west and north are at right-angles, we can visualize the movement of the sailboat in the form of a right-angled triangle as shown in the attached figure.
The sailboat moves leaves the port at P and reach O after sailing 12 km west. From point O, again it moves towards north 9 km and reach the point S.
PS = ?
Using the Pythagoras theorem, we have from right-angled triangle SOP,
Thus, the sailboat is at a distance of 15 km from the port.
Answer: B 2
Step-by-step explanation:
If you look at the graph, you can see it goes up every hour by 2.
So therefore your answer will be 2.
Hope this helps!
40/50 is the ratio because the cos formula is adjacent over hypotenuse and you can reduce it to 4/5 as a fraction :)
