Answer:

It is A [1st option]

Step-by-step explanation:

Use process of elimination.

The last 2 would not work since 3^0 is 1 not 0.

Then you can eliminate the 2nd option as it says 2^3^2 is 2^5 which is wrong... it would be 2^6

Therefore, it is A

Answer:A= 7

Step-by-step explanation:

y=mx+b

512=114x+134

subtract 134 from both sides of the equation,

378=114x

Divide 144 from both sides of the equation to get x by itself

x=6.25

Consider the equations y = √x and y = x^2 - 1

<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.
