Identify the angles of rotational symmetry for the figure.

1 answer:

3 0

I saw 180, 90, 45. That’s only because 360/8=45 so it’s symmetrical when rotated by a multiple of 45. Hope that helps

Answer: $f'(1)=\dfrac{4}{2y+1}$

<u>Step-by-step explanation:</u>

To find the tangent, you need to find the derivative with respect to x.

Then substitute x = 1 into the derivative.

Given: 0 = 2x² - xy - y²

Derivative: 0 = 4x - y' - 2yy'

Solve for y': 2yy' + y' = 4x

y'(2y + 1) = 4x

$y'=\dfrac{4x}{2y+1}$

$\text{Substitute x = 1:}\quad y'(1)=\dfrac{4}{2y+1}$

Factors of 27: 1; 3; 9; 27

GCF(18; 27) = 9
