Answer:

Step-by-step explanation:

f(x) = -2x² + 8x

f(3) = -2*(3)² +  8*3

     = - 2*9 + 24

     = - 18+ 24

f(3) = 6

f(1)= -2*(-1)² + 8*(-1)

   = -2*1  - 8

  = - 2 -8

f(1) = -10

A 2 cm x 2 cm x 2 cm cube holds 468 grains of rice. How many grains of rice would fit in a box with
Amiraneli [1.4K]
Let the Volume of the first cube be V1

V1 = 2 * 2 * 2

= 8 cm*3


Let the Volume of the second cube be V2

V2 = 6 * 2 * 12

= 144 cm*3


Now, cube1 with volume of 8 cm*3 holds 468 grains of rice.

Thus, 1 cm*3 volume can hold 58.5 grains of rice ( 468 / 8 = 58.5)

Cube2 has volume of 144 cm*3.

Hence, it can hold 8424 grains of rice ( 144 * 58.5 = 8424)
