Answer:
$69.75
Step-by-step explanation:
60+0.15x is your expression.
Now, plug in 65 miles for x, as that is the changing value.
60+(0.15*65)
60+9.75
$69.75
 
        
             
        
        
        
Answer:
602
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).
