What's bigger 2/3 or 4/5

Answers

The best thing to do is either to find a common denominator or convert them to decimals.
I will find a common denominator.
A common denominator of 3 and 5 is 15.
You multiply the first fraction by 5
2*5= 10
This then becomes 10/15
You then multiply the second by 3.
4*3= 12
Therefore, this becomes 12/15
As the second of these fractions is larger, this means that 4/5 is larger.
The alternative method is to put them into decimals, in which case 2/3= 0.66 and 4/5= 0.8
Hope this helps :)

find the LCD (15) and change the fractions to: 10/15 and 12/15. compare the numerators, 12 is greater, so **4/5** is greatest

What is the radius of the circle given the equation x 2 - 6x + y 2 + 10y - 2 = 0?

Answers

we are given

$x^2-6x+y^2+10y-2=0$

Firstly, we will change it into standard equation of circle

that is

$(x-h)^2 +(y-k)^2 =r^2$

where r is radius

(h,k) is center

now, we can change our equation into this form

To change our equation into this form, we need to complete x square and y square

$x^2-6x+y^2+10y-2=0$

step-1: Move 2 on right side

$x^2-6x+y^2+10y-2+2=0+2$

$x^2-6x+y^2+10y=2$

step-2: Complete x square

$x^2-2*3*x+y^2+10y=2$

$x^2-2*3*x+3^2+y^2+10y=2+3^2$

$(x-3)^2+y^2+10y=2+3^2$

step-3: Complete y square

$(x-3)^2+y^2+2*5*y=2+3^2$

$(x-3)^2+y^2+2*5*y+5^2=2+3^2+5^2$

$(x-3)^2+(y+5)^2=2+3^2+5^2$

step-4: Combine right side terms

$(x-3)^2+(y+5)^2=36$

$(x-3)^2+(y+5)^2=6^2$

now, we can compare with our equation

and we will get

radius =r=6...............Answer

center=(h,k)=(3,-5)........................Answer

Which Exponential equation is equivalent to the logarithmic equation below?
C= in 3

Answers

Answer

e^c = 3

Step by step explanation

The general exponential equation is y = a^x, where "a" is the base and "x" is the exponent.

We are given c = ln 3

Here the base is "e"

e^c = e^ln 3

e^c = 3 [base "e" and "ln" get cancelled because they are inverse]

Therefore, the answer is e^c = 3

Hope you will understand the concept.

Thank you.
