Simplify the expression to a + bi form

Gnesinka [82]

-√4 + √(-48) + √121 + √(-108)

= -√(2²) + √(-1 • 3 • 4²) + √(11²) + √(-1 • 2² • 3³)

= -2 + 4√3 i + 11 + 6√3 i

= 9 + 10√3 i

What is an equation of the line that is perpendicular to y-3 =-4(x+2)

serg [7]

Answer:

$y - 3 = \frac{1}{4}(x+2)$ or choose any line with slope 1/4

Step-by-step explanation:

The slope of this line is -4. The slope of the line perpendicular to this line will be the negative reciprocal or 1/4.

Write the equation using the slope m=1/4 and the point slope form.

$y-y_1=m(x-x_1)\\y-3=\frac{1}{4}(x+2)$

This is the equation of the line that is perpendicular and passes through the same point (-2,3) as the equation listed.
