2.145 is divisible by which numbers<br> 2<br> 6<br> 5<br> 3​
mariarad [96]

Answer:

  • 3 and 5 if "." marks thousands
  • 2, 3, 5, 6 if "." is a decimal point

Step-by-step explanation:

The number 2145 is not even, so will not be divisible by 2 or 6. It ends in 5 so is divisible by 5. Its sum of digits is 12, which is divisible by 3, so the number is divisible by 3.

2145 is divisible by 3 and 5.

2.145 is divisible by all of these numbers:

  2.145/2 = 1.0725

  2.145/6 = 0.3575

  2.145/5 = 0.429

  2.145/3 = 0.715

_____

Here, we take the mixed number to be divisible if the decimal representation of the quotient is a terminating decimal fraction.

Given the foci of (8,0) and the difference of the focal radii = 6, find the equation of the hyperbola
k0ka [10]

Given :

The foci of hyperbola are (8,0) and (-8,0) .

The difference of the focal radii = 6.

To Find :

The equation of the hyperbola.

Solution :

We know, distance between foci is given by :

2c = 8 - (-8)

c = 8

Also, difference between the foci or focal distance is given by :

2a = 6

a = 3

Now, we know for hyperbola :

b^2 +a^2 = c^2\\\\b^2={c^2-a^2}\\\\b^2 = 64-9\\\\b^2 = 55

General equation of hyperbola is :

\dfrac{x^2}{a^2}+\dfrac{y^2}{b^2}=1\\\\\dfrac{x^2}{9}+ \dfrac{y^2}{55}=1

Hence, this is the required solution.
