Answer:

Area of rectangle, f(x)=2x^2-2x-4.

Step-by-step explanation:

We are given with side lengths of a rectangle are (2x-4) units and (x+1) units. It is required to find the area of rectangle.

The area of a rectangle is equal to the product of its length and breadth. It is given by :

A=L\times B

Let us consider, L = (2x-4) units and B = (x+1) units

Plugging the side lengths in above formula:

A=(2x-4)\times (x+1)

A=2x^2+2x-4x-4\\\\A=2x^2-2x-4

So, the function that models the area of a rectangle is f(x)=2x^2-2x-4.

The rent for an apartment is represented by R(a) = 2.00a + 50.00, where a is the area of the apartment in square feet. The rent
QveST [7]

Answer:

<em>The correct option is:  D)  S(a) = 2.00a + 100.00; shift 50 units up</em>

Step-by-step explanation:

The rent for an apartment is represented by  R(a) = 2.00a + 50.00

Now, the rent increases by $50.00 when the apartment is furnished. So, the rent of a furnished apartment will be:  (2.00a+50.00+50.00) = (2.00a+100.00) dollar

Thus the new function will be:   S(a)= 2.00a+100.00

<u>As the output of the original function is increased by 50.00, so the graph of the original function will shift 50 units upward</u>.

Please help and EXPLAIN

Okay, all of these pairs add up to 1 or 100%, except for one pair. I'll convert them all to decimals, so all must add up to 1.

3/8 = 0.375
0.625 + 0.375 = 1

62% = 0.62
0.38 + 0.62 = 1

7/8 = 0.875
0.875 + 0.125 = 1

70% = 0.70
1/3 <span>≈</span> 0.33
0.70 + 0.33 = 1.03

So the last pair of probabilities(70%, 1/3) does not belong with the other three because it does not add up to 1 like the others.
