Write each polynomial function in standard form , classify it by degree and determine the end behavior of its graph Y=12-x^4

1 answer:

4 0

In standard form, zero is always on the right:
y = 12 - x^4
y + x^4 - 12 = 0

End behavior:
As x approaches ∞, y approaches -∞
As x approaches -∞, t approaches -∞

The USS Enterprise was 1,123 feet in length.

Kitty [74]

Answer:

The scale for a model that is 30 inches long is 449.2 inches.

The scale for a model that is 2 feet long is 561.5 feet.

Step-by-step explanation:

Consider the provided information.

The USS Enterprise was 1,123 feet in length.

Part (A) What is the scale for a model that is 30 inches long?

1 feet = 12 inches.

First convert the length of USS enterprise in inches.

1×1,123 feet = 12×1,123 inches

1,123 feet = 13476 inches

Divide original length with the length of model.

The scale for the model is:

$\frac{13476}{30}=449.2\ inches$

Hence, the scale for a model that is 30 inches long is 449.2 inches.

Part (B) What is the scale for a model that is 2 feet long?

Since, both the units are in feet, so simply divide original length with the length of model.

The scale for the model is:

$\frac{1123}{2}=561.5\ feet$

Hence, the scale for a model that is 2 feet long is 561.5 feet.

A system of equations has 1 solution. If 4x – y = 5 is one of the equations, which could be the other equation?

postnew [5]

Answer:

D: 2y = 8x - 10

Step-by-step explanation:

A: y = 4x + 5. This has a slope of -4 Yes it could work.

B: y = 4x - 5. No It does not work

C: 2y = 8x - 10. The slope is 8/2 = 4. So No it could not work.

<u>D: -2y = 8x - 10. The slope is 8/-2 = -4. Yes This Does work! :)</u>

To rent a certain meeting room, a college charges a reservation fee of $19 and an additional fee of $6 per hour. The chemistry c

ivanzaharov [21]

T= # of rental hours

Multiply number of hours rented by the cost per hour, add that total to the reservation fee. The total needs to be less than $91.

Reservation + ($ per hr * # hrs) < $91

$19 + $6t < $91
subtract 19 from both sides

6t < 72
divide both sides by 6

t < 12

ANSWER: To spend less than $91, they need to rent the room less than 12 hours.

Hope this helps! :)

4x(3x − 7) − 19x2<br> the 2 behind the x is an exponent

marin [14]

Answer:

-7x(x + 4)

Step-by-step explanation:

Not sure exactly what you're doing with this, but I know you're not solving it for x because there's no " = " there so I am assuming you're simplifying it as much as possible. I'm going with that.

First thing is to distribute through the parenthesis by multiplying 4x by 3x and then 4x by -7 to get:

$12x^2-28x-19x^2$

Now combine like terms to get

$-7x^2-28x$

The last thing you could do now is pull out what's common between each of those terms which is -7x. When you do that, you're left with

-7x(x + 4)
