Answer:
The vector equation
The parametric equation
Step-by-step explanation:
Given
Required
The vector equation
First, we calculate the position vector of the point.
This is represented as:
The vector equation is then calculated as:
Open bracket
Collect like terms
Factorize
The parametric equation is represented as:
Where
By comparison:
First we would need to make a diagram, and from the given it would seem like it is a right triangle with the height as 760 ft. We have an angle given 89°18' which would need to be converted to degrees form, which is 89.3<span>°.
Now we would need to look for the ground distance, meaning the adjacent of the triangle. Since we have been given the angle and the height (which is the opposite side from the angle) we use the trigonometric function cotangent.
</span><span>760 Cot <span>[<span><span>(<span>89.3</span>)</span>∘</span>]</span>= 9.29 ft, that is the answer.</span>
Hello there,
There is the simple trick to convert repeating decimal into the fraction. For example,
0.11111111...
We see that 1 was repeating many times, so we just need to take 1 over 9 or 1/9 is your final answer.
Or
0.23232323...
You just need to put 23/99 to get that answer. Hope it help!
