What is the remainder when the polynomial f(x)=3x^3-4x^2+2x+8 is divided by (x-5)

allsm [11]

Answer:

remainder = 290

Step-by-step explanation:

$\frac{3x^3-4x^2+2x+8}{x-5}$

= 3x² + 11x + 57 + $\frac{290}{x-5}$

quotient = 3x² + 11x + 57 and remainder = 290

Is each line parallel, perpendicular, or neither parallel nor perpendicular to a line whose slope is −34?

Zigmanuir [339]

Given:

The slope of a line is $-\dfrac{3}{4}$ .

To find:

The lines in the options are parallel, perpendicular or neither parallel nor perpendicular to the given line.

Solution:

We know that the slopes of parallel lines are equal.

The slope of line Q and the slope of given line are same, i.e., $-\dfrac{3}{4}$ . So, the line Q is parallel to the given line.

The slope of a perpendicular line is the opposite reciprocal of the slope of the line because the product of slopes of two perpendicular lines is -1.

The slope of a line is $-\dfrac{3}{4}$ . It means the slope of the perpendicular line must be $\dfrac{4}{3}$ . So, the line N is perpendicular to the given line.
