Answer:

<h3>The answer is option D.</h3>

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

Slope of the line using points ( 5 , - 1) and

( - 5 , 2) is

m = 2+1/ -5-5 = - 3 / 10

Equation of the line using point ( 5 , - 1) is

y + 1 = -3/10(x - 5)

y = -3/10x + 3/2 - 1

The final answer is

<h3>y = - 3/10x + 1/2</h3>

Hope this helps you.

Find the inner product for (3,1,4) * (2,8,-2) and state whether the vectors are perpendicular.
erica [24]

Answer:

6

Not perpendicular

Step-by-step explanation:

Generally, when we have two vectors, (x1, x2, x3...xn) and (y1, y2, y3...yn) the inner product is given by x1*y1+(x2*y2)+(x3*y3).....(xnyn)

If the above sum is zero then the two vectors are perpendicular else they are not.

Given (3, 1, 4) and (2, 8, -2)

The inner product will be

(3*2)+(1*8)+(4*-2)=6+8-8=6

The inner product is 6 hence not perpendicular.
