Answer:

Thus, the dimensions of the desk in the drawing are 4 cm long and 2 cm wide.

Step-by-step explanation:

Scaling

The scale factor established to represent a desk 2 meters long and 1 meter wide is:

1 centimeter = 0.5 meter

We need to convert the real dimensions to the scaled dimensions. To complete the task, it's a good idea to multiply the real dimensions by the ratio:

[tex]\displaystyle \frac{1\ cm}{0.5\ m}[/tex]

to get the scaled dimensions.

The length of 2 meters is scaled to:

[tex]\displaystyle 2\ m\frac{1\ cm}{0.5\ m}=4\ cm[/tex]

And the width of 1 meter is scaled to:

\displaystyle 1\ m\frac{1\ cm}{0.5\ m}=2 cm

Thus, the dimensions of the desk in the drawing are 4 cm long and 2 cm wide.

Answer:

70.574

Step-by-step explanation:

7.1 × 9.94= A

9.94

7.1

-------

70.574

A= 70.574

(when multiplying decimals do not line up the dot and solve it as if there was no decimals point. when you get your answer count the amount of digits on the right side of the number going to the left on your answer.

in this case there are three digits on the right side of the decimals you count three spaces to the left of your answer wich is 574. put the decimal point infront of the 5 and you get you answer. 70.574

Answer:

x=2

Step-by-step explanation:

To find the axis of the simmetry of parabola ( the curve of the quadratic function) we have to find the x of the top point of the parabola.

The x= -12/-(2*3)= 2

So the axis of the symmetry is the line x=2

x=-3

Answer:

All x-values larger than or equal to 5 ([tex]x\geq 5[/tex])

Step-by-step explanation:

Notice that the graph of

[tex]f(x)=-\sqrt{x}[/tex]

is defined for all real x-values larger than or equal to zero, since the square root is defined only for such values.

When we shift the graph to the right 5 units, the function becomes:

[tex]f(x)=-\sqrt{x-5}[/tex]

then the radicand x-5 must be larger than or equal to 0 in order to render real values. Then we have:

[tex]x-5\geq 0\\x\geq 5[/tex]

which means that now the Domain becomes the following set (in set builder notation):

[tex]Domain=\left \{ x\,|\,x\geq 5 \right \}[/tex]

Trick question, either 8 legs because of the two chairs or none.

Step-by-step explanation:

The dogs and everything aren't on the ground. I think the anwser is either 8 or none.

Answer:

The number of legs on the ground are 10.

Step-by-step explanation:

Given information:

2 dogs , 4 horses and 1 giraffe and a duck are laying on the bed.

3 chickens are flying over two chairs .

Now, in the riddle the specific type of leg is not mentioned but the information is given about the bed and chair.

So, one need to consider the legs of bed and chair too, also the person entering in the room is on the ground so the legs of the person will also be counted.

Hence, total number of legs on the ground will be:

legs of (1 bed + 2 chairs + 1 person)

Hence

Number of legs (N) = 4+8+2

N=10

Hence, the number of legs on the ground are 10.

Answer:

0.502

Step-by-step explanation:

There are 327 members of a professional organization, of which 164 are over the age of 50.

The probability that a randomly selected member of the organization is over the age of 50 is calculated as:

Probabilty = 164 members/327 members

= 0.501529052

Approximately = 0.502

Therefore, the probability of the randomly selected member is over the age of 50 is 0.502.

Simplify   ———————————————————

                 2x - 1        

Checking for a perfect cube :

3.1    10x3 - 3x2 - 7x + 3  is not a perfect cube

Trying to factor by pulling out :

3.2      Factoring:  10x3 - 3x2 - 7x + 3  

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

Group 1:  -7x + 3  

Group 2:  10x3 - 3x2  

Pull out from each group separately :

Group 1:   (-7x + 3) • (1) = (7x - 3) • (-1)

Group 2:   (10x - 3) • (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 :

3.3    Find roots (zeroes) of :       F(x) = 10x3 - 3x2 - 7x + 3

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  10  and the Trailing Constant is  3.

The factor(s) are:

of the Leading Coefficient :  1,2 ,5 ,10

of the Trailing Constant :  1 ,3

Let us test ....

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

  10x3 - 3x2 - 7x + 3  

can be divided with  2x - 1

remainder                0

Quotient :  5x2+x-3  Remainder:  0  

Trying to factor by splitting the middle term

3.5     Factoring  5x2+x-3  

The first term is,  5x2  its coefficient is  5 .

The middle term is,  +x  its coefficient is  1 .

The last term, "the constant", is  -3  

Step-1 : Multiply the coefficient of the first term by the constant   5 • -3 = -15  

Step-2 : Find two factors of  -15  whose sum equals the coefficient of the middle term, which is   1 .

     -15    +    1    =    -14  

     -5    +    3    =    -2  

     -3    +    5    =    2  

     -1    +    15    =    14  

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Canceling Out :

3.6    Cancel out  (2x-1)  which appears on both sides of the fraction line.

Final result :

 5x2 + x - 3

The quotient when 10x³-3x²-7x+3 divided by 2x-1 is -21/8.

To calculate the quotient of the equation 10x³-3x²-7x+3 when it is divided by 2x-1, we use the quotient theorem.

Remainder theorem

The quotient theorem states that if f(x) is divided by x-a, then the remainder is f(a).

From the question,

Given:

The quotient is f(1/2), we substitute the value of x as 1/2 into equation 1

Hence, The quotient when 10x³-3x²-7x+3 divided by 2x-1 is -21/8.
