R^2+3r+5-r^3/r is a quadratic/cubic/linear polynomial?
Sergeu [11.5K]

r^2+3r+5-r^3/r is  a linear polynomial

S<u>tep-by-step explanatio</u>n:

based on the highest power of the variables of a polynomial, it can be classified as linear,polynomial, quadratic polynomial,cubic polynomial etc.

In a linear polynomial, the highest power of the variable is 1. The general form of a linear polynomial is ax+b

In a quadratic polynomial, the highest power of the variables is 2.The general form of quadratic polynomial is ax^2+bx+c

In a cubic polynomial,the highest power of variable is 3.The general form of cubic polynomial is ax^3+bx^2+cx+d.

Take the given question and simplify it

r^2+3r+5-r^3/r=r^2+3r+5-r^2\\=3r+5

It is of the form ax+b. Hence it is  a linear polynomial.

Container A is cylinder with a radius of 10 units and a height of 10 units. A right cone has been carved from its base and has a
sergij07 [2.7K]

Answer:

Step-by-step explanation:

The formula for determining the volume of a cylinder is expressed as

Volume = πr²h

Where

r represents the radius of the cylinder.

h represents the height of the cylinder.

From the information given,

Height = 10 units

Radius = 10 units

Volume = π × 10² × 10

The formula for determining the volume of a cone is expressed as

Volume = 1/3πr²h

Height = 10 units

Base = 10 units

Volume = 1/3 × π × 10² × 10

Since the cone has been carved from the cylinder, the statement that derives the formula to find the volume of container B is

π × 10² × 10 - 1/3 × π × 10² × 10

in 2014 the attendance at jefferson schools fall festival was 650 in 2015 the attendance was 575 what was the percent change
Gnoma [55]

There was 11.54% decrease in attendance.

Step-by-step explanation:

Attendance in 2014 = Old value = 650

Attendance in 2015 = New value = 575

Change = New value - Old value

Change = 575 - 650 = -75

The negative sign indicates a decrease in attendance.

Decrease percentage = \frac{Change}{Old\ value}*100

Decrease\ percent=\frac{75}{650}*100\\\\Decrease\ percent=\frac{7500}{650}\\\\Decrease\ percent=11.538\%

Rounding off to nearest hundredth

Decrease percent = 11.54%

There was 11.54% decrease in attendance.

The following cube has a volume of 8000 cm3. Find the length of one side of the cube.
Artemon [7]
<span>Vcube = Ledge^3
8000cm^3 = Ledge^3

use the cube root of each side and you have the measure of an edge in cm.

8000^(1/3) = 20
  every edge is 20 cm

20^2 = 400
The area of each face is 400 cm^2. </span>
