Answer:

I hope this helps-How to define a logarithmic unction-

Step-by-step explanation:

Therefore, the (multiple-valued) logarithmic function of a nonzero complex variable z=reiΘ is defined by the formula logz=lnr+i(Θ+2nπ)(n∈Z).

Some basic properties of the function logz are the following:

log(z1z2)=logz1+logz2.

log(z1z2)=logz1−logz2.

There may hold Log(z1z2)≠Logz1+Logz2.

What is an angle between a side of a polygon and the extension of its adjacent side

jek_recluse [69]

I would say that the angle would be an exterior angle because it's usually between the side of the polygon connected by a line as an extension of the adjacent side.

here's an example. hope it helps!

Answer:

The real zeros of f(x) are x = 0.3 and x = -3.3.

Step-by-step explanation:

Solving a quadratic equation:

Given a second order polynomial expressed by the following equation:

$ax^{2} + bx + c, a\neq0$ .

This polynomial has roots $x_{1}, x_{2}$ such that $ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})$ , given by the following formulas:

$x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}$

$x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}$

$\bigtriangleup = b^{2} - 4ac$

In this problem, we have that:

$f(x) = x^{2} + 3x - 1$

$a = 1, b = 3, c = -1$

$\bigtriangleup = 3^{2} - 4*1*(-1) = 13$

$x_{1} = \frac{-3 + \sqrt{13}}{2*1} = 0.3$

$x_{2} = \frac{-3 - \sqrt{13}}{2*1} = -3.3$

The real zeros of f(x) are x = 0.3 and x = -3.3.

What is the length of the hypotenuse? If necessary, round to the nearest tenth.

PolarNik [594]

Answer:

hypotenuse = 25 yards

Step-by-step explanation:

Use pythagorean theorem

c^2 = a^2 + b^2 where c = hypotenuse and 'a' and 'b' are the legs

hyp^2 = 24^2 + 7^2

hyp^2 = 625

hyp = 25 yd
