<em>Write the number as a fraction of 1 (one):</em>

Simultaneously multiply the numerator and denominator by 10 <em>as many times as the digits after the comma (separation between the integer part and the fractional part of the number):</em>

<em>Since we have</em> 3 numbers after the comma, multiply the numerator and denominator by 1000. So,

<em>Note that </em>multiplying by 10 is the same as moving the decimal <em>point one place to the right.</em>

Once this fraction is irreducible, that is, it is in reduced form, <em>we can no longer simplify it.</em><u> The answer is the previous fraction.</u>

Answer:

(a) $P" = (-4,-3)$

(b) $(x,y) \to (4,-8)$

Step-by-step explanation:

Given

$P = (4,3)$

Solving (a): Reflect across x and y-axis.

Reflection across x-axis has the following rules

$(x,y) \to (x,-y)$

So, we have:

$P' = (4,-3)$

Reflection across y-axis has the following rules

$(x,y) \to (-x,y)$

So, we have:

$P" = (-4,-3)$

Hence, the new point is: (-4,-3)

Solving (b): Rx . Do,2 (2,4)

$R_x \to$ reflect across the x-axis

Reflection across x-axis has the following rules

$(x,y) \to (x,-y)$

So, we have:

$(2,4) = (2,-4)$ ---- when P is reflected across the x-axis

$D_{o,2} \to$ dilate by a scale factor of 2

The rule is:

$(x,y) \to 2 * (x,y)$

So, we have

$(x,y) \to 2 * (2,-4)$

Open bracket

$(x,y) \to (4,-8)$

Rewrite the following expression as a single logarithm 2log(x+3)-3log(x-7)+5log(x-2)-log(x^2)

mixer [17]

The rewritten form of the expression as a single logarithm is; log {(x+3)²(x-2)^5}/(x-7)³(x²).

<h3>What is the rewritten form of the expression?</h3>

The expression given in the task content can be rewritten as a single logarithm by virtue of the laws of logarithms as follows;

2log(x+3)-3log(x-7)+5log(x-2)-log(x^2)

= log(x+3)² - log(x-7)³ +log(x-2)^5-log(x^2)

= log {(x+3)²(x-2)^5}/(x-7)³(x²)

Mr.Brown has 110 fiction books and 90 non-fiction books on his shelf. what percent of her library is non fiction?

Vanyuwa [196]

Answer:

45%

Step-by-step explanation:

Given

Number of fiction books = 110

Number of non fiction books = 90

Total number of books = 110 + 90 = 200

% of non fiction books

= number of non fiction books divided by the total number of books multiplied by 100%

That’s

90/200 x 100%

0.45 x 100%

45%

45% of her library is nonfiction

klemol [59]

Answer:

Each of the 4 people will get 1/24 of the original cake

Step-by-step explanation:

The fractional part of cake left out is 1/6

This remaining cake is to be divided among four people.

Thus, each person will get

fractional part of cake left/total number of people

i.e 1/6/4

= 1/24

Each of the 4 people will get 1/24 of the original cake
