A circle and a square can intersect at how many points
SSSSS [86.1K]

If the circle has the same center as the diagonals of a square and the radius of the circle is smaller than 1/2 the diagonal of the square but larger than 1/2 the length of the side of a square, then there are 8 points of intersection -- 2 at each corner of the square.

If the radius of the circle is smaller than 1/2 the side length of the square and the center is as described above, there are no points of intersection.

If the circle is located outside the square it can have 1 tangent point or 2 intersection points depending on the location conditions of the circle in relation to the square.

If f(x) = 2x+4, which of the following is the inverse of f(x)?
Mrrafil [7]

By definition of inverse function,

f\left(f^{-1}(x)\right) = x

Given that f(x) = 2x + 4, solve for the inverse of f :

f\left(f^{-1}(x)\right) = 2 f^{-1}(x) + 4 = x \implies f^{-1}(x) = \dfrac{x-4}2

(I'm not entirely sure which answer that corresponds to from the choices provided...)

Given cos theta = √3/4 and sin theta < 0. What is the value of sin theta? ​
Diano4ka-milaya [45]

Answer:

\sqrt{ \frac{13}{16} }

Step-by-step explanation:

cos \: theta =   \frac{ \sqrt{3} }{4} \\ sin \: theta =  \sqrt{1 -  {cos}^{2} theta}  \\  =   \sqrt{1 - {( \frac{ \sqrt{3} }{4} ) }^{2}}  \\  =  \sqrt{1 -  \frac{3}{16}} \\  =  \sqrt{ \frac{13}{16} }
