The number (√5+2)/(√5-2)

Mathematics
1 answer:
goldenfox [79]3 years ago
3 0

Answer:

b:  irrational

Step-by-step explanation:

  (√5+2)

--------------  is given.

  (√5 - 2)

If we multiply numerator and denominator by (√5+2), we succeed in removing the square root symbol from the denominator:

(√5+2)(√5+2)

---------------------

(√5+2)(√5- 2)

and the denominator becomes 5 - 2, or 3.  The denominator is now rational, but the numerator still involves the square root symbol, so overall the given number is irrational.

None of the given options are matching. For the expression after putting the value 2 on the place of x. We will get 10 for expression 1 and 0 for the expression 2.

<h3>How can we find the solution to an equation?</h3>

We do same operations on both the sides so that equality of both expressions doesn't get disturbed.

Solving equations generally means finding the values of the variables used in it for which the considered equation is true.

The given equation is;

Equation 1;

\rm 3x+4

Equation 2;

x+6-3x-2

After putting the value 2 on the place of x we get;

Equation 1;

\rm  = 3x+4

=3 \times 2+4 \\ =10

Equation 2;

= x+6-3x-2\\\\\ =2+6-3\times 2-2 \\\\ =2+6-6-2\\\\ =8-6-2 \\\\  = 0

Hence, the none of the given options are matching.

What is the linear diameter (in meters) of an object that has an angular diameter of 22
Mumz [18]

Answer: 0.15 m

Step-by-step explanation:

Using the small angle formula

D= kd/206265 where

k= 22 and d= 1400

D= 22 x 1400/206265

D=0.149 m

Hence the linear diameter is 0.15 m.
