Given:

Transformation is

$T:(x,y)\to (x-5,y+3)$

To find:

The image of A(2,-1).

Solution:

The rule of transformation is

$(x,y)\to (x-5,y+3)$

To find the image of A(2,-1). Put x=2 and y=-1 in the above rule of transformation.

$A(2,-1)\to A'(2-5,-1+3)$

$A(2,-1)\to A'(-3,2)$

Therefore, the image of A(2,-1) is A'(-3,2).

X^2 + 32x + 256 = 1<br>please show steps

$\boxed{x_{1}=-15} \\ \\ \boxed{x_{2}=-17}$

<h2>Explanation:</h2>

In this case, we have the following equation:

$x^2+32x+256=1$

But we can write this equation as:

$x^2+32x+256=1 \\ \\ Subtract \ -1 \ from\ both \ sides: \\ \\ x^2+32x+256-1=1-1 \\ \\ x^2+32x+255=0$

So this final result is a quadratic equation written in Standard Form ( $ax^2+bx+c=0$ ). We need to find the solutions to this equations, so let's use quadratic formula:

$x=\frac{-b \pm \sqrt{b^2-4ac}}{2a} \\ \\ a=1 \\ b=32 \\ c=255 \\ \\ \\ x=\frac{-32 \pm \sqrt{(32)^2-4(1)(255)}}{2(1)} \\ \\ x=\frac{-32 \pm \sqrt{1024-1020}}{2} \\ \\ x=\frac{-32 \pm \sqrt{4}}{2} \\ \\ x=\frac{-32 \pm 2}{2} \\ \\ Finally, \ two \ solutions: \\ \\ \boxed{x_{1}=-15} \\ \\ \boxed{x_{2}=-17}$

Answer:

The answers to the question above are given below:

Step-by-step explanation:

Question: What is a discrete probability distribution?

<u>Answer</u>

A discrete distribution is very important in data research as it shows in tabular form the probabilities that can be found in a list of distribution values and their individual probabilities in counted data. Usually, from the pool of distribution of numbers, the discrete distribution shows the probability of having countable numbers out of the pool.

<u>Question:</u> Choose the correct answer below. A. A discrete probability distribution exclusively lists probabilities. B. A discrete probability distribution lists each possible value a random variable can assume, together with its probability. C. A discrete probability distribution lists each possible value a random variable can assume. D. None of the above

The correct answer is: option B "discrete probability distribution lists each possible value a random variable can assume, together with its probability."

Question: What are the two conditions that determine a probability distribution?

<u>The correct answer is</u>:

1. Since each value may not be zero, each probability must include between 0 and 1.

2. When probabilities are totaled, it must give 1.

The perimeter of a rectangular field is 380 yd. the length is 70 yd longer than the width. find the dimensions.

GaryK [48]

P=2L+2W
380=2*70+2W
380=140+2W
2W=240
W=120

The dimensions are 70 yd and 120 yd

Hope this helps!
