Answer:

[B] 4k²+ 6k - 1

Explanation:

(4k² + 8k + 2) - (2k + 3)

Remove Parenthesis

4k² + 8k + 2 - 2k + 3

-2k + 3: -2k - 3

= 4k² + 8k + 2 - 2k - 3

Simplify

4k² + 8k + 2 - 2k - 3: 4k²+ 6k - 1

= 4k²+ 6k - 1

Given tan of theta = -2 and pi/2; find cos(2theta)
Nata [24]

Given tan of theta = -2 and pi/2; find cos(2theta)
The identity of cos (2 theta)= cos(2\theta )=\frac{1-tan^2\theta }{1+tan^2\theta }
Given tan of theta = -2 and pi/2.
So, let's plug in tan theta= -2
cos(2\theta)= \frac{1-(-2)^2}{1+(-2)^2}
=\frac{1-4}{1+4} (Squaring)
=\frac{-3}{5} (simplifying)
So, cos ( 2 theta) = -3/5.
Now we can plug in tan theta = π/2
cos(2\theta)= \frac{1-(π/2)^2}{1+(π/2)^2}
= \frac{1-pi^2/4}{1+pi^2/4} (Squaring)
=\frac{4-pi^2}{4+pi^2} Simplifying
So, cos ( 2 theta)= -3/5 and (4-pi^2)/(4+pi^2)

20 POINTS! 1 question PERPENDICULAR LINES
garik1379 [7]
If the line is perpendicular, that means the slope has to be opposite, so it will have a slope of -1/2

Fill in the point that it has to pass through on y and x

1=-1/2(0) + b

1=0+b

1=b

Then go back to the standard form y=mx + b and fill in the slope and y intercept

Y= -1/2x + 1
