Answer:
csc(θ) = 1.1662
cos(θ) = 0.5145
Step-by-step explanation:
I attach the image of your question in the picture below
We know the values of the adjacent and opposite cathetus
tan(θ) = Opposite / Adjacent
tan(θ) = 5/3 = 1.666
θ = tan^-1 (5/3)
θ = 59.0362 °
Now that we have the angle, we can easily find the value of the expressions needed
csc(θ) = 1 / sin(θ) = 1/ (0.85749) = 1.1662
cos(θ) = 0.5145
Using it's critical points, it is found that the least possible degree of the polynomial graphed above is 4.
<h3>What are the critical points of a function?</h3>The critical points of a function are the values of x for which:
At these critical points, the behavior of the function changes from increasing to decreasing or vice versa.
If a function has n critical points, the least possible degree is of n + 1.
From the changes in behavior of the graph, the function has critical points at:
.
The function has 3 critical points, hence the least possible degree of the polynomial graphed above is 4.
