$|a|= \left\{\begin{array}{ccc}a&for\ a\geq0\\-a&for\ a \ \textless \ 0\end{array}\right\\\\Examples:\\|2|=2\ because\ 2\geq0\\|0|=0\ because\ 0\geq0\\|-5|=-(-5)=5\ because\ -5 \ \textless \ 0\\|-100|=-100\ because\ -100 \ \textless \ 0$

|-3| + |3| = 3 + 3 = 6

Find the coordinates of the point which divides the join of (-1,7) and (4.-3) in the ratio 2:3 ??

d1i1m1o1n [39]

<h2><u>Q</u><u>u</u><u>e</u><u>s</u><u>t</u><u>i</u><u>o</u><u>n</u><u>:</u><u>-</u></h2>

Find the coordinates of the point which divides the join of (-1,7) and (4,-3) in the ratio 2:3 ?

<h2><u>Solution</u>:-</h2>

Let the given points be A(-1,7) and B(4,-3)

Now,

Let the point be P(x, y) which divides AB in the ratio 2:3

Here,

<h3> ${ \bf x \: = \frac{m_1 x_2 \: + \: m_1 x_1}{m_1 \: + \: m_2}}$ </h3>

Where,

$m_1$ = 2 , $m_2$ = 3

$x_1$ = -1 , $x_2$ = 4

$\therefore$ Putting values we get,

x = $\frac{2 \: × \: 4 \: + \: 3 \: × \: -1}{2 \: + \: 3}$

x = $\frac{8 \: - \: 3}{5}$

x = $\frac{5}{5}$

x = 1

Now,

Finding y

<h3> ${ \bf y \: = \frac{m_1 y_2 \: + \: m_2 y_1}{m_1 \: + \: m_2}}$ </h3>

Where,

$m_1$ = 2 , $m_2$ = 3

$x_1$ = 7 , $x_2$ = -3

$\therefore$ Putting values we get,

y = $\frac{2 \: × \: -3 \: + \: 3 \: × \: 7}{2 \: + \: 3}$

y = $\frac{-6 \: + \: 21}{5}$

y = $\frac{15}{5}$

y = 3

Hence x = 1, y = 3

So, the required point is P(x, y)

= P(1, 3)

<h3>The coordinates of the point is P(1, 3). [Answer]</h3>

How do you evaluate logarithms? Explain using an example or mathematical evidence to support your answer.

kenny6666 [7]

Answer: Explanation below.

Step-by-step explanation:

First of all you need to know how to convert a logarithm into an exponential expression. The property is:

$log_Bx=n$

This is the same as: $B^n=x$

Example 1:

$log_99=$

We are trying to find what to raise 9 to, in order to get a result of 9.

$9^x=9$

When you have same bases, you equal exponents.

$x=1$

Therefore; $log_99=1$

Example 2:

$log_232=$

$2^x=32$

In this case, we have to make sure both sides have the same base. 32 can have a base of 2 if expressed as: $2^5$ which is 2*2*2*2*2

Rewriting this example we have;

$2^x=2^5$

Since we have the same base, we equal exponents.

$x=5$

Therefore; $log_232=5$

Example 3:

$log_3729=$

$3^x=729$

729 can have a base of 3 if expressed as: $3^6$

$3^x=3^6$

$x=6$
