Answer:

4 • (3x4 + 2)

 ———————

      x2    

Step-by-step explanation:

Step  1  :

            8

Simplify   ——

           x2

Equation at the end of step  1  :

  8    

 —— +  12x2

 x2    

Step  2  :

Rewriting the whole as an Equivalent Fraction :

2.1   Adding a whole to a fraction

Rewrite the whole as a fraction using  x2  as the denominator :

           12x2     12x2 • x2

   12x2 =  ————  =  —————————

            1          x2    

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

8 + 12x2 • x2     12x4 + 8

—————————————  =  ————————

     x2              x2  

Step  3  :

Pulling out like terms :

3.1     Pull out like factors :

  12x4 + 8  =   4 • (3x4 + 2)

Polynomial Roots Calculator :

3.2    Find roots (zeroes) of :       F(x) = 3x4 + 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  3  and the Trailing Constant is  2.

The factor(s) are:

of the Leading Coefficient :  1,3

of the Trailing Constant :  1 ,2

Let us test ....

  P    Q    P/Q    F(P/Q)     Divisor

     -1       1        -1.00        5.00    

     -1       3        -0.33        2.04    

     -2       1        -2.00        50.00    

     -2       3        -0.67        2.59    

     1       1        1.00        5.00    

     1       3        0.33        2.04    

     2       1        2.00        50.00    

     2       3        0.67        2.59    

Polynomial Roots Calculator found no rational roots

Final result :

 4 • (3x4 + 2)

 —————————————

      x2

Find the distance between the two points.

Answer:

13

Step-by-step explanation:

(4,-5)(-1,7)

If you make a triangle and use the Pythagorean Theorem, the two legs have a distance of 5 and 12. 5^{2}+12{2}=25+144=169. The square root of 169 is 13.

I would like to get some information of how to do this...​
Inessa05 [86]

Answer:

The area is approximately 30.69 cm^2.

Step-by-step explanation:

To solve this problem, we first have to recognize that the side of the block is a rectangle with a semicircle missing.  This means that to find the area, we must find the area of the rectangle and then subtract the area of the semicircle.  Using the respective formulas, we get the following expression for area:

A = (length * width) - (1/2*pi*r^2)

Now, we must plug in the given values shown in the figure.  The length is 9 cm, the width is 4.5 cm, and the diameter is 5 cm.  However, the formula asks for the radius, which is simply half of the diameter, or 2.5 cm.  

A = (9 cm * 4.5 cm) - (1/2 * 3.14 * (2.5 cm)^2)

Next, we should perform the operations indicated inside the parentheses.

A = 40.5 cm^2 - 9.81 cm^2

Finally, we can subtract the two values (this represents taking away the area of the semicircle from the rectangle).

A = 30.69 cm^2

Therefore, the area of the side is approximately 30.69 cm^2.

Hope this helps!
