Classify -6x5 + 4x3 + 3x2 + 11 by degree.

Mathematics
1 answer:
LenaWriter [7]3 years ago
4 0

Answer:

This is a 5th degree single variable polynomial.

Step-by-step explanation:

We have to classify the given polynomial - 6 x^{5} + 4x^{3} + 3x^{2} + 11 by degree.

This is a 5th-degree single variable polynomial. (Answer)

Note :

(i) ax + b is the general form of a single degree i.e. linear single variable polynomial.

(ii) cx² + dx + e is the general form of two degrees i.e. quadratic single variable polynomial.

(iii) px³ + qx² + rx + s is the general form of three degrees i.e. cubic single variable polynomial.

In this way, the degree of a polynomial increases with the maximum power of the variable.

vredina [299]

Answer:

x= -40

Step-by-step explanation:

Cost

C(x)=1,600+20x

P(x)=100-x

Revenue=x*p(x)

=x*(100-x)

=100x-x^2

Cost=Revenue

1600+20x=100x-x^2

1600+20x-100x+x^2=0

1600-80x+x^2=0

Solve using quadratic formula

Formula where

a = 1, b = 80, and c = 1600

x=−b±√b2−4ac/2a

x=−80±√80^2−4(1)(1600) / 2(1)

x=−80±√6400−6400 / 2

x=−80±√0 / 2

The discriminant b^2−4ac=0

so, there is one real root.

x= −80/2

x= -40

How could the distance formula and slope be used to classify triangles and quadrilaterals in the coordinate plane?
S_A_V [24]

~ Use the distance formula to measure the lengths of the sides.

~ Use the slope to check whether sides are perpendicular and form right angles.

~ Use the slope to check whether the diagonals are perpendicular to each.

I hope this helps ^-^

Find two numbers whos diffrence is 16 and the product is 720
antiseptic1488 [7]

Answer:

the numbers who's difference is 16 and the product is 720 is

36 &20

Explanation:

to finding numbers you have to express the equation in a quadratic equation then Factor it.

since the two numbers have a difference of 16 you can say that the first number is x and the second number is x -16 then their product is 720.

x(x-16)=720

x²-16x=720

x²-16x-720=0

(x-36)(x+20)

there are two possible value of x but since you are looking for the positive value of x, choose the positive value of x the first number is 20.

To find the second number

x-16=20

x=20+16

x=36

the second number is 36

<u>Now </u><u>to </u><u>check</u>

<u>3</u><u>6</u><u>-</u><u>2</u><u>0</u><u>=</u><u>1</u><u>6</u>

<u>2</u><u>0</u><u>*</u><u>3</u><u>6</u><u>=</u><u>7</u><u>2</u><u>0</u>
