Answer:

a) f(0)=2

b)f(2)=-4

c)f(0)+f(2)=-2

d)f(3)*f(-2)=-56

e)f(0):f(2)=-1/2

Step-by-step explanation:

f(x) =-3x+2

a) f(0)=-3*0+2=2

b) f(2)=-3*2+2=-6+2=-4

c) f(0)+f(2)=2-4=-2

d)f(3)*f(-2)=-7*8=-56

f(3)=-3*3+2=-9+2=-7

f(-2)=-3*(-2)+2=6+2=8

e)f(0):f(2)=2/(-4)=-1/2

Find the rectangular coordinates of the point with the polar coordinates (3,3/2_ )

meriva

Polar coordinates: $(r,\theta)$

$r=3,\theta= \frac{3\pi}{2}$

Rectangular coordinates: $(x,y)=(r \cos{\theta},r \sin{\theta})$

$x=r \cos{\theta}=3 \cos{ \frac{3\pi}{2} }=3 \times 0=0
\\ y=r \sin{\theta}=3 \sin{ \frac{3\pi}{2} }=3 \times (-1)=-3$

Rectangular coordinates are (0,-3).
