Answer:
See graph attached.
The path of the curve, as t increases goes from the top of the curve going down, following a parabola symmetric in y=5.
Step-by-step explanation:
We have the following parametrics equations:
We can graph the variables x and y in a xy-plane following the values of t within the interval defined.
To do that we compute the values for x and y for every t in the interval and graph it.
The path of the curve, as t increases goes from the top of the curve going down, following a parabola symmetric in y=5.
<h3>Answer: 35.4</h3>
====================================================
Explanation:
Let x be the reference angle where the question mark is located.
Opposite this angle x is 27. The adjacent side is 38.
Use the tangent ratio to tie the two sides together
tan(angle) = opposite/adjacent
tan(x) = 27/38
x = arctan(27/38)
x = 35.3947958 .... which is approximate
x = 35.4
Be sure that your calculator is in degree mode. The notation "arctan" refers to "arctangent" which is the same as inverse tangent. Your calculator should have a button labeled to help compute this.
