Answer:
36
Step-by-step explanation:
4*6=24
3*4=12
24+12=36
X/4 = 4.3/2.5
x/4 = 1.72
x = 1.72 x 4
x = 6.88
S= 70w + 750
s(19) = 70w x 19+350= 1680
so its 1680
Answer:
c
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).
