What is 247,039 rounded to the nearest thousand

1 answer:

6 0

Answer:
247,000

Explanation:
To round a number to the nearest thousand, we check the digit in the hundreds position:
1- If the digit is less than 5, then we round down. This means that we simply convert all digits after the thousands to zero and that's it
2- If the digit is equal to or more than 5, then we round up. This means that we add one to the thousands digit and then convert all digits after the thousands to zero.

In the given number 247039, the number in the hundreds position is 0. This means that we will round down

Therefore, 246039 rounded to the nearest thousand would simply give 247000

Hope this helps :)

If x<0 and y>0, determine the sign of the real number x-y/xy ...?

Ludmilka [50]

If x<0 and y>0, then the sign of the real number x-y/xy would be positive. If x is negative and y is positive then x-y is negative and xy is negative. A negative number divided by another negative number would be positive. Hope this answers the question.

write the equation in standard form for the hyperbola with vertices ( – 12,0) and (12,0), and foci ( – 13,0) and (13,0).

Mashcka [7]

Standard form for the hyperbola with vertices ( – 12,0) and (12,0), and foci ( – 13,0) and (13,0) is $\frac{x^{2} }{144}-\frac{y^{2} }{25}=1$

Hyperbola is a plane curve generated by a point so moving that the difference of the distances from two fixed points is a constant.

Given,

The Vertices of the hyperbola = (-12,0) and (12,0)

Foci = (-13,0) and (13,0)

a=12

ac=13

c= $\frac{13}{12}$

We know,

c= $\sqrt{1+\frac{b^{2} }{a^{2} } }$

$c^{2}=1+\frac{b^{2} }{a^{2} } \\(\frac{13}{12} )^{2}=1+\frac{b^{2} }{144} \\\frac{169}{144}=1+ \frac{b^{2} }{144} \\\frac{b^{2} }{144} =\frac{25}{144}\\ b^{2}=25$

The equation of the hyperbola is

$\frac{x^{2} }{a^{2} }-\frac{y^{2} }{b^{2} }=1\\ \frac{x^{2} }{144 }-\frac{y^{2} }{25 }=1$

Hence, the standard form for the hyperbola with vertices ( – 12,0) and (12,0), and foci ( – 13,0) and (13,0) is $\frac{x^{2} }{144}-\frac{y^{2} }{25}=1$
