Consider the two functions described below. Function 1 describes the cost, y, to park in a parking lot for x hours. There is a f
Len [333]

Statement B explains correctly that the parking garage charges a higher rate per hour than the parking lot. Statements B and D are the same.

Step-by-step explanation:

Step 1:

For the parking lot, there is a flat fee of $7.00 and then a charge of $1.00 every hour.

So if a vehicle was parked for 1 hour charges are 7 + 1 (1) = $8,

If parked for two hours charges are 7 + 1 (2) = $9.

Step 2;

To understand the pricing of the parking garage, we must plot the points of the graph.

The points on the graph are (0, 4), (1, 6), (2, 8), (3, 10), (4, 12), (5, 14)...

So for the parking garage, there is a flat fee of $4 and then a charge of $2.00 every hour.

So if a vehicle was parked for 1 hour charges are 4 + 2 (1) = $6,

If parked for two hours charges are 4 + 2 (2) = $8.

Step 3:

Comparing both the parking lot and the parking garage, we get that the flat fee for the parking lot is higher while the parking charges for an hour are higher for the parking garage which is statement B.

Statement B and D are the same.

What is an important requirement for an emergency fund​
wariber [46]

Answer:

According to most financial experts, it's wise to save at least six months of net living expenses in an emergency fund. So if a family requires $3,000 a month to pay all of its expenses, then it should strive to accumulate $18,000 in an interest bearing emergency savings account.

Basically, you are asked to find the equation for total revenue. In economics, total revenue is equal to the the quantity multiplied with price.

Total Revenue = Price*Quantity
Thus,
R(x) = P(x) * N(x)
R(x) = (0.6x + 5)(<span>−0.2x</span>³<span> + x</span>²<span> − 2x + 9)
R(x) = -0.12x</span>⁴ + 0.6x³ - 0.12x² + 5.4x - x³ + 5x² - 10x + 45
<em>R(x) = -0.12x⁴ - 0.4x³ + 4.88x² - 4.6x + 45</em>
