Answer:

\boxed{\sf 200\pi}

Step-by-step explanation:

We know that the volume of a cone:-

\boxed{\sf  \pi r^2\cfrac{h}{3}}

(r = 10) (h = 6)

\sf \pi \times 10^2\times\cfrac{6}{3}

<u>Divide numbers:-</u>

\sf \cfrac{6}{3}=\boxed{2}

\sf 10^2\times \:2\pi

\sf 100\times \:2\pi

<u>Multiply numbers:-</u>

\boxed{\sf 200\pi}

Therefore, your answer is 200π³

We could also multiply 200 by 3.14 which will give you 628 units³.

What is the quotient x-3/4x^2+3x+2
Elena L [17]

Answer:

STEP

:

Equation at the end of step 1

 (((x3) -  22x2) -  3x) +  2  = 0  

STEP

2

:

Checking for a perfect cube

2.1    x3-4x2-3x+2  is not a perfect cube

Trying to factor by pulling out :

2.2      Factoring:  x3-4x2-3x+2  

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1:  -3x+2  

Group 2:  x3-4x2  

Pull out from each group separately :

Group 1:   (-3x+2) • (1) = (3x-2) • (-1)

Group 2:   (x-4) • (x2)

Bad news !! Factoring by pulling out fails :

The groups have no common factor and can not be added up to form a multiplication.

Polynomial Roots Calculator :

2.3    Find roots (zeroes) of :       F(x) = x3-4x2-3x+2

Polynomial Roots Calculator is a set of methods aimed at finding values of  x  for which   F(x)=0  

Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers  x  which can be expressed as the quotient of two integers

The Rational Root Theorem states that if a polynomial zeroes for a rational number  P/Q   then  P  is a factor of the Trailing Constant and  Q  is a factor of the Leading Coefficient

In this case, the Leading Coefficient is  1  and the Trailing Constant is  2.

The factor(s) are:

of the Leading Coefficient :  1

of the Trailing Constant :  1 ,2

Let us test ....

  P    Q    P/Q    F(P/Q)     Divisor

     -1       1        -1.00        0.00      x+1  

     -2       1        -2.00        -16.00      

     1       1        1.00        -4.00      

     2       1        2.00        -12.00      

The Factor Theorem states that if P/Q is root of a polynomial then this polynomial can be divided by q*x-p Note that q and p originate from P/Q reduced to its lowest terms

In our case this means that

  x3-4x2-3x+2  

can be divided with  x+1  

Polynomial Long Division :

2.4    Polynomial Long Division

Dividing :  x3-4x2-3x+2  

                             ("Dividend")

By         :    x+1    ("Divisor")

dividend     x3  -  4x2  -  3x  +  2  

- divisor  * x2     x3  +  x2          

remainder      -  5x2  -  3x  +  2  

- divisor  * -5x1      -  5x2  -  5x      

remainder             2x  +  2  

- divisor  * 2x0             2x  +  2  

remainder                0

Quotient :  x2-5x+2  Remainder:  0  

Trying to factor by splitting the middle term

2.5     Factoring  x2-5x+2  

The first term is,  x2  its coefficient is  1 .

The middle term is,  -5x  its coefficient is  -5 .

The last term, "the constant", is  +2  

Step-1 : Multiply the coefficient of the first term by the constant   1 • 2 = 2  

Step-2 : Find two factors of  2  whose sum equals the coefficient of the middle term, which is   -5 .

     -2    +    -1    =    -3  

     -1    +    -2    =    -3  

     1    +    2    =    3  

     2    +    1    =    3  

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Theory - Roots of a product

3.1    A product of several terms equals zero.  

When a product of two or more terms equals zero, then at least one of the terms must be zero.  

We shall now solve each term = 0 separately  

In other words, we are going to solve as many equations as there are terms in the product  

Any solution of term = 0 solves product = 0 as well.

Parabola, Finding the Vertex:

3.2      Find the Vertex of   y = x2-5x+2

Parabolas have a highest or a lowest point called the Vertex .   Our parabola opens up and accordingly has a lowest point (AKA absolute minimum) .   We know this even before plotting  "y"  because the coefficient of the first term, 1 , is positive (greater than zero).  

Each parabola has a vertical line of symmetry that passes through its vertex. Because of this symmetry, the line of symmetry would, for example, pass through the midpoint of the two  x -intercepts (roots or solutions) of the parabola. That is, if the parabola has indeed two real solutions.  

Parabolas can model many real life situations, such as the height above ground, of an object thrown upward, after some period of time. The vertex of the parabola can provide us with information, such as the maximum height that object, thrown upwards, can reach. For this reason we want to be able to find the coordinates of the vertex.  

For any parabola,Ax2+Bx+C,the  x -coordinate of the vertex is given by  -B/(2A) . In our case the  x  coordinate is   2.5000  

Plugging into the parabola formula   2.5000  for  x  we can calculate the  y -coordinate :  

 y = 1.0 * 2.50 * 2.50 - 5.0 * 2.50 + 2.0

or   y = -4.250

Parabola, Graphing Vertex and X-Intercepts :

Root plot for :  y = x2-5x+2

Axis of Symmetry (dashed)  {x}={ 2.50}  

Vertex at  {x,y} = { 2.50,-4.25}  

x -Intercepts (Roots) :

Root 1 at  {x,y} = { 0.44, 0.00}  

Root 2 at  {x,y} = { 4.56, 0.00}

Can someone please help with this problem
notsponge [240]

Answer:

31 degrees

Step-by-step explanation:

well each three point of a triangle equals 180

so 20+35= 55   180-55= 125

now if the exterior angle is 156 and it should equal 180 the interior angle would be 24 degrees

now we have 24 and 125 so angle ? = 31

Assume that when adults with smartphones are randomly​ selected, 57​% use them in meetings or classes. If 9 adult smartphone use
forsale [732]

Answer: 0.9617

Step-by-step explanation:

Given : The proportion of adults use their phones in meetings or classes : p=0.57

Number of adults randomly selected : n= 9

Let x be the random variable that represents the number of adults use their phones in meetings or classes.

By using binomial probability formula, to find the probability of getting success in x trials.

P(x)=^nC_xp^x(1-p)^{n-x}

The probability that at least 3 of them use their smartphones in meetings or classes will be :-

P(x\geq3)=1-P(x

Hence, the required probability is 0.9617 .

What would be the difference at the end of one year between the simple interest earned on a deposit of $450 at 4.5% and the comp
Len [333]

Answer: $0

Step-by-step explanation:

The formula for simple interest is expressed as

I = PRT/100

Where

P represents the principal

R represents interest rate

T represents time in years

I = interest after t years

From the information given

T = 1 year

P = $450

R = 4.5%

Therefore

I = (450 × 4.5 × 1)/100

I = 2025/100

I = 20.25

For compound interest,

Initial amount deposited into the account is $450 This means that the principal,

P = 450

It was compounded annually. This means that it was compounded once in a year. So

n = 1

The rate at which the principal was compounded is 4.5%. So

r = 4.5/100 = 0.045

It was compounded for just a year. So

t = 1

The formula for compound interest is

A = P(1+r/n)^nt

A = total amount in the account at the end of t years. Therefore

A = 450 (1+0.045/1)^1×1

A = 450(1.045) = $470.25

Compound interest = 470.25 - 450 = 20.25

The difference is 20.25 - 20.25 = 0
