To convert from rectangular coordinates (x,y) to polar coordinates (r, θ), the following equations should be used:
r = sqrt( x^2 + y^2)
<span>θ = tan^-1 (y/x)
</span>
Substituting (-3,3) accordingly to the equations, we obtain r equal to 3*sqrt(2) and θ equal to -π/4. Thus, the polar coordinates equivalent to (-3,3) is (3*sqrt(2), -π/4).
3.341 to the nearest tenth is 3.3
The correlation coefficient r of the data set is <em>-0.28</em>
A trapezium is a quadrilateral. The option that is true for the trapezium is A, D, and E.
<h3>What is Trapezium?</h3>
A trapezium is a quadrilateral which is having a pair of opposite sides as parallel and the length of the parallel sides is not equal.
The given trapezium is an isoceles trapezium. Therefore, the properties of the trapezium that are true for KLMJ are:
- KL is parallel to JM
- ∠J is supplementary ∠K
- ∠J is congruent to ∠M (Valid only for isoceles trapezium).
Hence, the option that is true for the trapezium is A, D, and E.
