Area of a quarter circle = 1/4 * pi * r^2

= 1/4 * pi * 4^2 = 12.6 m to 3 sig figs.

perimeter = 4 + 4 + 1/4 * 2 pi * 4 = 14.3 to 3 sig figs.

A question on notation: Does sine inverse have an exponent? If not, why is there a negative one there? If so, why can't you just

NNADVOKAT [17]

Answer:

Step-by-step explanation:

When you write

-1

y = sin x, the "-1" is not an exponent, but rather an indication of "inverse function."

-1

y = sin x can also be written as y = arcsin x.

No exponentiation here, and no division here.

Given the three vertices W(−1, 4), X(−3, −2), and Y(3, −4), what are the coordinates of Z that make quadrilateral WXYZ a square?

prohojiy [21]

Answer:

I don't see how the three existing points could ever become a square with the addition of a foiurth point.

Step-by-step explanation:

See the attached image.

A square would require that all angles be 90 degrees. The given points are the top three points on the graph. If we enter the two equations that intersect these points (blue and black lines), we can see that the angle on top is not 90 degrees. I can't see that this could ever be a square with a fourth point, z. I did find a value for z that make the four points a parallelogram.
