Step-by-step explanation:
18h=252
9h=?(x)
9×252=18x
2268=18x
2268/18=x
x=126
Answer:
<em>I </em>=2000(0.075)4= $600
Step-by-step explanation:
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).
