Answer:

6 roots

Step-by-step explanation:

we know that

The number of roots is determined by the degree of the polynomial. They may be real or complex.

In this problem we have

$f(x)=3x^{6}+2x^5+x^4-2x^3$

The degree refers to the highest exponent of the polynomial

Since this is a 6th degree polynomial, it will have 6 roots

What is the equation of the circle with center (0, 0) that passes through the point (–4, –6)?

eimsori [14]

Answer:

Option 4: x^2+y^2 = 52

Step-by-step explanation:

Given

Centre at origin

Point on circle = (-4, -6)

The distance between origin and point on circle will be the radius of the circle

So,

$r = \sqrt{(x_2-x_1)^{2}+(y_2-y_1)^{2}}\\r= \sqrt{(-4-0)^2+(-6-0)^2} \\r = \sqrt{(-4)^2+(-6)^2}\\r = \sqrt{16+36} \\r = \sqrt{52}$

As the center is at origin the standard equation will be:

$x^2+y^2 = r^2\\$

Putting the value of r

$x^2+y^2 = (\sqrt{52})^2\\x^2+y^2 = 52$

Hence, last option i.e. Option 4 is correct ..
