Rudik [331]

the domain is all the real numbers, or (-infinite <x<infinite)

the range is y>=-4

axis of symetry is x= -1

vertex is (-1,-4)

the parabola opens upwards

x intercepts (-3,0) and (1,0)

y intercepts (0,-3)

plsss helppp need it fastt .. what is the volume of this figure answer your answer in the box . 4ft 3ft 8ft 2ft 6ft
PolarNik [594]

Answer:

e

Step-by-step explanation:

The cube on the top, the one with the width of 4 is Cube 1.

The other one is Cube 2.

The length of the cube is 4, the width 2, and the height 5.

We know the length is 4 because we can look at the side, where both measurements 6 ft and 3 ft can be found.

We know that the height is 5 because for Cube 2, the height is 3. The total height is 8, so we subtract 3 from 8. We get our difference of 5.

V = l x w x h

V = (4)(2)(5)

V = (8)(5)

V = 40.

Cube 2 has a length is 6, the width 2, and the height 3.

V = l x w x h

V = (6)(2)(3)

V = (12)(3)

V = 36

We add the volumes of both cubes.

40 + 36 = 76

probs not right but hope it helped :)
