Arrange the fraction in asending and desending order 4/5 , 2/15 , 2/30

Andrej [43]

Answer:

See below

Step-by-step explanation:

Given fractions

4/5, 2/15, 2/30

To arrange the fractions we need to bring them to common denominator

LCM(5,15,30) = 30
4/5 = 24/30
2/15 = 4/30
2/30

In ascending order

2/30, 4/30, 24/30

Reverse order

24/30, 4/30, 2/30

What is the general form of the equation of a circle with center at (a, b) and radius of length m?

pochemuha

The equation of a circle with center (h,k) and radius r is
$(x-h)^2+(y-k)^2=r^2$

convert it to that form by comleting the square for the x and y terms
or, we can just expand what we know

expand $(x-a)^2+(y-b)^2=m^2$ and make it equal to 0
so expanding we get
$x^2-2ax+a^2+y^2-2by+b^2=m^2$
minus m^2 from both sides
$x^2-2ax+a^2+y^2-2by+b^2-m^2=0$
arranging in decreasing power order with m² at the end
$x^2+y^2-2ax+-2by+a^2+b^2-m^2=0$
that is option A

answer is A
