If log a = x and log b = y, then log (ab2) equals

mylen [45]

Answer:

The answer for log(ab²) is x + 2y.

Step-by-step explanation:

You have to apply Logarithm Law,

$log(a) + log(b) \: ⇒ \: log(a \times b)$

$log( {a}^{n} ) \: ⇒ \: n log(a)$

In this question, you have to seperate it out :

$log(a {b}^{2} ) = log(a) + log( {b}^{2} )$

$log( {b}^{2} ) = 2 log(b)$

$let \: log(a) = x$

$let log(b) = y$

$log(a {b}^{2} ) = log(a) + 2 log(b)$

$log(a {b}^{2} ) = x + 2y$

Both of them intersect at point (-3,5)

So, (-3,5) is the solution of the system of equations.

If the radius of a circle proportional to the circumference of the circle. Justify your answer. If the radius of a circle is 18

postnew [5]

circumference of a circle (C)

C = πd or 2πr ( because d 2 x r)

r= 18 miles given

d= diameter

r= radius

d = 2 x r

d = 2 x 18 = 36 miles

2) C = πd

C = 3.14 x 36 = 113.04 miles

3) approximate measure of C = 22/7 x 36= 113.14 miles
