Why is the product of negative reciprocals always -1?
erik [133]

Answer:

please check the explanation.

Step-by-step explanation:

Let suppose we have a number = n  

  • n≠0    

The negative reciprocal of 'n' = -1/n

Taking the product of 'n' and its negative reciprocal '-1/n':

n\left(-\frac{1}{n}\right)

remove parentheses: (-a) = -a

=-n\frac{1}{n}

\mathrm{Multiply\:fractions}:\quad \:a\times \frac{b}{c}=\frac{a\:\times \:b}{c}

=-\frac{1\times \:n}{n}

\mathrm{Cancel\:the\:common\:factor:}\:n

=-1

Canceling the common factor (the number itself) will bring -1.

It proves that the multiplication of any number and its negative reciprocal will always yield -1.

What is the value of x rounded to nearest tenth
Ivahew [28]

Answer:

6.5 cm

Step-by-step explanation:

Here, <em>the tangent line squared is equal to the secant line times the secant line outside the circle</em>.

That is <em>20.2² = 14.7 * (14.7 + 2x)</em> --> it is 2x because the secant goes through <em>the whole circle</em>.

Simplify: <em>408.04 = 216.09 + 29.4x</em>

Subtract: <em>191.95 = 29.4x</em>

Divide: <em>x = 6.528911565</em> ≈ 6.5 cm
