<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.
Alright, lets get started.
In the question given that glacier receded 4 feet a day for a period of 25 days.
Which shows in 1 day, it recedes = 4 feet
means in 1 day, the height of the glacier gets shorter = 4 feet
So, in 25 days, the height of the glacier gets shorter = 4 * 25
So, in 25 days, the height of the glacier gets shorter
feet
It means the glacier will get 100 feet shorter at the end of the period of 25 days. : Answer
Hope it will help :)
Answer:
X=45
Step-by-step explanation:
X=180-[60+75]=45
Your answer is 40mm
3+12+12+13
=40
