Which of the following correctly describes the end behavior of the polynomial
galben [10]

Answer:

A. Both ends go down.

General Formulas and Concepts:

<u>Algebra II</u>

  • End behavior - what the y-values are approaching as x approaches negative infinity or infinity

Step-by-step explanation:

If we graph the function, we can see that when x goes to -∞, y also goes to -∞.

We also see that when x goes to ∞, y <em>still</em> goes to -∞.

Therefore, both ends of the graph would head towards -∞, making A. the correct answer choice.

Tim's electricity costs 4.3 ¢ a kilowatt hour. How much will it cost to run the following appliances for 10 hours? (round to the
steposvetlana [31]

Answer:

a Dryer @ 4,000 watts. Cost = 172 cents

a Heater @ 1,500 watts. Cost = 64.5 cents

a Radio @ 40 watts. Cost =  1.72 cents.


Step-by-step explanation:

Given that cost of 1 kilowatt hour = 4.3 cents.

Then cost of 1 kilowatt for 10 hours = 4.3*10 = 43 cents.


4000 watts = 4000/1000 kilowatt = 4 kilowatts

Then cost for running a Dryer for 10 hours = 4*43 = 172 cents.

-----------

1500 watts = 1500/1000 kilowatt = 1.5 kilowatts

Then cost for running a Heater for 10 hours = 1.5*43 = 64.5 cents.

-----------

40 watts = 40/1000 kilowatt = 0.04 kilowatts

Then cost for running a Radio for 10 hours = 0.04*43 = 1.72 cents.
