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).
The answer is b because 7 plus 2 equals 9 and a equals whole amount then his current amount is A-9
Answer:
Pretty sure it's "only i"
Step-by-step explanation:
A constant rate of change means that something changes by the same amount during equal intervals.
$30 is the same amount whereas 10% could vary.
Hope this helps.
