If x -1/7,evaluate x²+1/x²​

Mathematics
1 answer:
SCORPION-xisa [38]3 years ago
6 0

Answer:

given \: x =  -  \frac{1}{7}

x {}^{2}  +  \frac{1}{x {}^{2} }

(  - \frac{1}{7} ) {}^{2}  +  \frac{1}{  (  - \frac{1}{7} ) {}^{2} }

\frac{1}{49}  +  \frac{1}{ \frac{1}{49} }

\frac{1}{49}  +  \frac{1 \times 49}{1}

\frac{1}{49}  + 49

\frac{2402}{49}  \: or \: 49.02

Quick anyone know the answer to this problem?
sweet-ann [11.9K]

Answer:

D

Step-by-step explanation:

Factor the numerators/ denominators

10 - 5 = 5(2a - 1) ← common factor of 5

4a² - 1 = (2a - 1)(2a + 1) ← difference of squares

[ Change ÷ to × and turn second fraction upside down ]

= \frac{2a+1}{5(2a-1)} × \frac{(2a-1)(2a+1)}{10a}

[ cancel the factor (2a - 1) on the numerator/denominator ] leaving

= \frac{(2a+1)^2}{5(10a)} = \frac{(2a+1)^2}{50a}

Convert the complex number z = 4 - 10i from rectangular form to polar form.​
mrs_skeptik [129]

ANSWER

r = 2 \sqrt{29} ( \cos(292 \degree)  + \sin(292 \degree))

EXPLANATION

The polar form of a complex number ,

z = x + yi

is given by:

z = r( \cos( \theta)  + i \sin( \theta) )

where

r =  \sqrt{ {x}^{2} +  {y}^{2}  }

The given complex number is:

z = 4 - 10i

r =  \sqrt{ {4}^{2}  +  {( - 10)}^{2} }

r =  \sqrt{16  + 100}

r =  \sqrt{116}  = 2 \sqrt{29}

And

\theta=  \tan^{ - 1}(\frac{ y}{x} )

\theta=  \tan^{ - 1}(\frac{  - 10}{4} )

\theta=  292 \degree

Hence the polar form is :

r = 2 \sqrt{29} ( \cos(292 \degree)  + \sin(292 \degree))

Explain why 1/6 is greater than 1/8 but less than 1/3
valentina_108 [34]
You can read fractions as one number divided by another. So 1/6 is equivalent to 1 divided by 6. It is then selfevident that the larger the denominator the smaller the number. If you have one cake and divide it between 3, 6 or eight people, three people will get a larger slice than 6 people sharing the same cake. And 6 people will get a larger slice than 8 people dividing the same cake.
