Answer:

15y8 – 7y3 + y; eighth degree trinomial

Step-by-step explanation:

To write the polynomial in standard from, the degrees of the monomials need to decrease from left to right. Reorder the monomials to get 15y8 – 7y3 + y.

The polynomial has three terms, which makes it a trinomial. The monomial with the greatest exponent is 15y8, an eighth degree term. This makes the expression an eighth degree trinomial.

Juliette [100K]

Answer:

Yes, more than half are being used. (292 out of 546 used)

Step-by-step explanation:

The first part of this problem is to determine the total amount of seats on the plane so we can determine what half of the seats would be.

1st class has 14 seats.

Business-class has 64 seats.

And the 4 economy classes have 117 each, meaning 117 * 4 = 468

So the total amount of seats are 14 + 64 + 468 = 546

So half that amount would be 273.

Now we can determine the number of seats being used.

1st class has (6/7) * 14 = 12 seats used

Buisness-class has (7/16) * 64 = 28 seats being used

Economy has 4 * (7/13) * 117 = 4 * 63 = 252 seats being used

So the total amount of used seats would be 12 + 28 + 252 = 292.

Note that 292 is greater than 273, so there is indeed more than half the seats on the plane being used.

Cheers.

Rectangle ABCD has a perimeter of 32 units and will

AlladinOne [14]

Answer:

Check below

Step-by-step explanation:

1) Check the rectangle below with a line k, the axis of rotation in the center of the figure.

2) Since it has a perimeter of 32 units and it is to be rotated about the line, the solid to be created it is a cylinder. As you can see below.

3) Let's calculate its radius, based on the information given, i.e. the perimeter:

$2p=32\\2p=b+b+h+h\\2p=2(b+h)\\2(b+h)=32\\b+h=16\\b.h=60\\\\b=10\: and \:h=6$

Since the line of rotation is the center, and the radius is half the line segment of the basis, then the radius is 5.
