Find f(-2) f(x)=9x^2-5x+2

f(-2) means replace x in the equation with -2:

f(-2)=9(-2)^2-5(-2)+2

= 9(4) +10 + 2

= 36 +10 + 2

= 48

f(-2) = 48

A cylinder has a volume of 1884 cm^3. Find the same radius and height as the cylinder

astra-53 [7]

Answer:

628

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2h

The volume of a cone is

V = 1/3 pi r^2 h

If the radius and height are the same

The cone will have 1/3 the volume of a cylinder

The cone has 1/3 the volume of a cylinder given the same height and radius

1/3(1884) =628
