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 <span> 1.

Encuentre el radio y el área de círculos cuya circunferencias tienen las siguientes medidas
Vadim26 [7]

Answer:

Los radios de los círculos son r_{1} \approx 9.995, r_{2} \approx 2.013, r_{3} \approx 7.592, respectivamente.

Las áreas de los círculos son A_{1} \approx 313.845, A_{2} \approx 12.730, A_{3} \approx 181.077, respectivamente.

Step-by-step explanation:

La circunferencia (s) se calcula mediante la siguiente fórmula:

s = 2\pi\cdot r (1)

Donde r es el radio del círculo.

Una vez hallado el radio, se determina el área de la figura geométrica (A) mediante la siguiente fórmula:

A = \pi\cdot r^{2} (2)

Si conocemos que las circunferencias son s_{1} = 62.8, s_{2} = 12.65 y s_{3} = 47.7, respectivamente:

1) Radios de los círculos

r_{1} = \frac{s_{1}}{2\pi}, r_{2} = \frac{s_{2}}{2\pi}, r_{3} = \frac{s_{3}}{2\pi}

r_{1} \approx 9.995, r_{2} \approx 2.013, r_{3} \approx 7.592

2) Áreas de los círculos

A_{1} = \pi\cdot r_{1}^{2}, A_{2} = \pi\cdot r_{2}^{2}, A_{3} = \pi\cdot r_{3}^{2}

A_{1} \approx 313.845, A_{2} \approx 12.730, A_{3} \approx 181.077

What is the value of x in the proportion below? 1/2/4=x/28
True [87]

Answer:

depends on whether you meant (1/2)/4  or 1/ (2/4)

Step-by-step explanation:

1/2                 x

---------- = -------------

4                   28

Using cross products

1/2* 28 = 4x

14 = 4x

Divide by 4

14/4 = 4x/4

7/2 =x

If you meant

1                 x

---------- = -------------

2/4                   28

1 * 28 = 2/4 x

28 = 1/2 x

Multiply each side by 2

28*2 = 1/2x*2

56 =x

Choose all of the transformations that would change a triangle into one that is similar, but not congruent. Which transformation
Vsevolod [243]

You didn't supply a list.  The so-called rigid transformations of translation, rotation and reflection create congruent triangles.

Generally it's dilation by a factor about a point is preserves similarity but not congruency.  Any transformation which includes such scalings but is otherwise rigid also preserves similarity but not congruency.
