What is the leading coefficient of the polynomial function? <br><br> y=-x^4+4x^2

attashe74 [19]

<h3>Answer: -1</h3>

Explanation:

The given equation is the same as y = -1x^4+4x^2

The leading term is the term with the largest exponent, so it's -1x^4

The leading coefficient is the coefficient of the leading term.

In short, we circle the first coefficient we see. This is assuming that the polynomial is in standard form where the exponents decrease when going from left to right.

A 60 room hotel is filled to capacity every night at a rate of $40 per room. The management wants to determine if a rate increa

Oxana [17]

Answer: to maximize profit the management must continue charging $40 per room because it will obtain a profit of $1,920 better than $1,870 if it rises the rate.

Step-by-step explanation:

<u>Profit without the increase</u>

60 (number of rooms) * $40 (rate per room) = $ 2,400

costs of day to service = 60 (rooms) * $8 (costs day to service)= $480

Total Profit = $2,400 - $480 = $1,920

<u>Profit with the increase</u>

55 (5 fewer than before) * 42 (rate with the increase) = $ 2,310

costs of day service 55 (rooms) * 8 ( costs day to service) = $440

Total Profit = $2,310 -$440 = $1,870

A project on Kickstarter.com was aiming to raise $15000 for a precision coffee press. They ended up with 714 supporters, raising

Leni [432]

For this, we can set up a proportion.
Their aim was 15000, so if they raised 100% of their goal, they wouldve raised exactly 15000.
They raised 557%, so how much did they make?

Proportion:

$15000 100%
$x 557%

Our expression would be x=$15000*557% divided by 100%, which would be $83550, so... a lot of money.

(we did an “x” formation with the proportion, ie “connected” x with 100, and “connected” 15k and 557. The number connecting to x is what we divide the equation by, and the other two are multiplied and then divided by the first number connecting to x. Otherwise we couldve calculated 557% of 15000 and gotten the same result. Whichever way is easier for you :) )
