Answer:

She needs 4 more marbles for the 9th jar.

Step-by-step explanation:

Multiples of 8:

M = {0, 8, 16, 24, 32, 40, 48, 56, ...}

First, she puts in the greatest possible number of marbles into each of the 1st 8 jars.

The total is the greatest multiple of 8 below 50, which is 48.

In each jar:

48/8 = 6

The remaining marbles are then put into the 9th jar.

50 - 48 = 2 in the 9th jar.

How many more marbles does she need for the 9th jar such that every jar has the same number of marbles?

All others have 6, the 9th has 2.

6 - 2 = 4

She needs 4 more marbles for the 9th jar.

$\qquad\qquad\huge\underline{\boxed{\sf Answer☂}}$

Let's solve ~

$\qquad \sf \dashrightarrow \: log_{4}(39.2)$

$\qquad \sf \dashrightarrow \: log_{4}( {2}^{3} \times {7}^{2} \times 10 {}^{ - 1} )$

$\qquad \sf \dashrightarrow \: log_{4}( {2}^{3} ) + log_{4}( {7}^{2} ) + log_{4}(10 {}^{ - 1} )$

$\qquad \sf \dashrightarrow \: log_{ {2}^{2} }( {2}^{3} ) + log_{ {2}^{2} }( {7}^{2} ) + log_{ {2}^{2} }(10 {}^{ - 1} )$

$\qquad \sf \dashrightarrow \: \frac{3}{2} log_{2}(2) + \frac{2}{2} log_{2}(7) - \frac{1}{2} log_{2}(10)$

$\qquad \sf \dashrightarrow \: \frac{3}{2} + a - \frac{b}{2}$

That's the required result ~

also you can take it's LCM and write it as :

$\qquad \sf \dashrightarrow \: \dfrac{2a - b + 3}{2}$

florin(x) contains the point (0,1), so the inverse of florin(x) must contain the point , which is not on the line g(x). The func

Alex787 [66]

Answer:

The function g(x) will not contain point (0,1).

Step-by-step explanation:

If a function contains a point then its inverse also contains the point.

Now, in this question florin(x) is a function that contains the point (0, 1).

And the inverse of the function florin(x) will also contain the point (0, 1).

But this inverse function is not g(x).

So, the function g(x) will not contain point (0,1). ( Answer )
