I was trying to figure it out but all i got was the meaning of the upside down U. so in the theory of a 9th grader i think...

you would have to distribute A' in to ( C U B)

because with the information i got it has to be in all so by distributing it would be in "all".

being a 9th grader i don't know if this helped but i hope it did just a little! and i deeply apologize if it doesn't.

<u>ANSWER TO PART A</u>

The given triangle has vertices $J(-4,1), K(-4,-2),L(-3,-1)$

The mapping for rotation through $90\degree$ counterclockwise has the mapping

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

Therefore

$J(-4,1)\rightarrow J'(-1,-4)$

$K(-4,-2)\rightarrow K'(2,-4)$

$L(-3,-1)\rightarrow L'(1,-3)$

We plot all this point and connect them with straight lines.

ANSWER TO PART B

For a reflection across the y-axis we negate the x coordinates.

The mapping is

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

Therefore

$J(-4,1)\rightarrow J''(4,1)$

$K(-4,-2)\rightarrow K''(4,-2)$

$L(-3,-1)\rightarrow L''(3,-1)$

We plot all this point and connect them with straight lines.

You can use GP in many ways.

Suppose you invested some money at somewhere.The money increases in a constant ratio.You can use geometric sequence in order to find your money after some years.
In science you can use it to find growth of bacteria which is exponential.

The square of a number, x, is 16 less than eight times the number. What is the number? Type the correct answer in the box. Use n

liraira [26]

Given :

The square of a number, x, is 16 less than eight times the number.

To Find :

The value of x .

Solution :

The mathematical equation with all given data is :

$x^2=8x-16\\\\x^2-8x+16=0\\\\x^2-4x-4x+16=0\\\\x(x-4)-4(x-4)=0\\\\(x-4)^2=0\\\\x=4$

Therefore , the value of x is 4 .

Hence , this is the required solution .
