Answer:
4
Step-by-step explanation:
Answer: 5.5 seconds
Since the penny is dropped and not thrown, the initial velocity is 0 and the initial height is given as 150m. Plugging these into the given equation result in
. To find how long it will take for the penny to hit the ground we set the equation equal to zero and solve for t. Since this doesn't factor, you'll need to use the quadratic formula:
. Since time cannot be negative, the answer will be the positive 5.5 seconds.
Given:
A plane flying a straight course observes a mountain at a bearing of 35° to the right of its course.
The distance between plan and mountain is 10 km.
A short time later, the bearing to the mountain becomes 45°.
Here NM is the distance between the plane from the mountain when the second bearing is taken.
We need to find the measure of NM.

The sum of the supplementary angles is 180 degrees.





We know that the sum of all three angles of the triangle is 180 degrees.






Consider the sine law.

Take the equation to find the measure of NM.





Hence the measure of NM is 8.1 km.
The plane is 8.1 km far from the mountain when the second bearing is taken.
