Answer:

Answers are below

Step-by-step explanation:

The axis of symmetry for f(x) is at x = 4 because it splits the function in half. I found it by looking at the vertex of the parabola and using the x-value as the axis of symmetry.

The axis of symmetry for h(x) is at x = -2 because it splits the function in half. I found it by looking at the vertex of the parabola and using the x-value as the axis of symmetry.

N is an odd number.

Answer:

True:

Step-by-step explanation:

First, you should know that the square of any odd number is also odd.

The easiest way to go about this is to plug in an odd number for n. Lets use 3:

Plug 3 into A:

$3^{2} -1=9-1=8$

Plug 3 into B:

$3(3-1)=9-3 = 6$

Plug 3 into C:

$(3-2)^{2} = 2^{2} = 4$

Plug 3 into D:

$3^{2} +2 = 9+2=11$

Plug 3 into E:

$3(3-2) = 9-6 = 3$

Plug 3 into F:

$(3-2)^{2}=1^{2} =1$

90units needed 8 units per case what's the #of cases & # of additional units

Kobotan [32]

Answer:

# of cases: 11

Additional units: 2

Step-by-step explanation:

If each case can hold 8 units, and we want to find the total # number of cases, we have to divide the # of units (8) for one case by the total # units (90).

As you can see, after dividing by 8, we have a total of 11 cases and a remainder of 2 units. The remainder will be the # of additional units because we cannot have another case filled with 8 units.
