<h3>Answer:</h3>
(x, y) ≈ (1.49021612010, 1.22074408461)
<h3>Explanation:</h3>
This is best solved graphically or by some other machine method. The approximate solution (x=1.49, y=1.221) can be iterated by any of several approaches to refine the values to the ones given above. The values above were obtained using Newton's method iteration.
_____
Setting the y-values equal and squaring both sides of the equation gives ...
... √x = x² -1
... x = (x² -1)² = x⁴ -2x² +1 . . . . . square both sides
... x⁴ -2x² -x +1 = 0 . . . . . polynomial equation in standard form.
By Descarte's rule of signs, we know there are two positive real roots to this equation. From the graph, we know the other two roots are complex. The second positive real root is extraneous, corresponding to the negative branch of the square root function.
The triangle that does not have the y angle, equate all of its angles to 180 degrees and solve for x. Once you solve for x, substitute that value to the angles in the other triangle, and then add them all up and equate it to 180 degrees to solve for y.
It would be B (530.7) because if you do 3.14 x 13 x 13 (Or to the second power) Then you get 530.66, the round to the nearest tenths
Answer:
The answer is "0.765 and 0.2353".
Step-by-step explanation:
Please find the complete question in the attached file.
In point a:
P(a substantive term only)
P(major health insurance only) 
P(both)
P(renewal) =P(insurance and renewal term only)+P (substantial and renewable health insurance only)+P (both and renew)

In point b:
In reality, the probability of having both life and major medical insurance provided the policyholder would renew next year


The graph went left 1 and up 6. You could complete the square to find out or just graph it!
Hope this helps!
