Step-by-step explanation:
n + n^2 = 6 n^2 + n - 6 = 0 factoring ___ (n + 3)(n - 2) = 0 n + 3 = 0 ___ n = -3 n - 2 = 0 ___ n = 2 two solutions
Answer:
n = -3, 2
Step-by-step explanation:
We're given:
The sum of a number and its square is 6Let the number be n.
The sum of a number and its square is 6⇒ [tex]n+n^2=6[/tex]
[tex]n+n^2=6[/tex]
⇒ Move everything to one side of the equation:
[tex]n+n^2-6=0[/tex]
⇒ Organize in [tex]ax^2+bx+c=0[/tex] form:
[tex]n^2+n-6=0[/tex]
⇒ Factor:
[tex]n^2-2n+3n-6=0\\n(n-2)+3(n-2)=0\\(n+3)(n-2)=0[/tex]
⇒ Use the zero-product property to find n:

1. Find the value of x in this figure.
Answers
Answer:
x = 30º
Step-by-step explanation:
Let's call the midpoint of OP, R.
The triangle of OQR would be an equilateral triangle since OQ = OR as they are both radii and is OQR and ORQ are 60º, ROQ is also 60º, making the triangle equilateral. Because tangents meet a circle at 90º, the angle RQP would be 30º and since angles on a straight line add to 180º, the angle QRP would be 180-ORQ which is 120º. Now we know the 2 angles in triangle of QRP so we can work out the final angle since angles in a triangle add to 180º. So:
180 - 120 - 30 = 30º.
x = 30º
This would also prove that QR and RP are the same since base angles in an isosceles triangle are equal.

Select one:
а. 1.7936
b. 0.7852
c.0.9633
d. 0.0367
Answers
The probability when x is greater than 120 is 0.0367. Then the correct option is D.
What is a normal distribution?The Gaussian Distribution is another name for it. The most significant continuous probability distribution is this one. Because the curve resembles a bell, it is also known as a bell curve.
The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.
The mean is 95 and the standard deviation is 14. Then the probability when x > 120 will be
The z-score will be
z = (120 - 95)/ 14
z = 1.7857
Then the probability will be
P(x > 120) = P(z > 1.7857)
P(x > 120) = 1 - P(x<120)
P(x > 120) = 1 - 0.96293
P(x > 120) = 0.0367

The similarities and differences in a non-fiction text look at how the subject or events are portrayed.
What is a non-fiction text?Comparing non-fiction texts can focus on the similarities between the texts - things they have in common. You can also contrast texts and focus on their differences - things that set the texts apart from each other. You could compare and contrast the following:
Form – What types of text (letter, news report, etc) are they?
Purpose – What job (persuading, informing, advertising) is each text doing?
Audience – Who is the intended reader of the text?
Subject matter – What are the texts about?
Language choices – What kinds of words, images or rhetorical devices are being used?
Structure – How is the text ordered?
Tone – What is the overall tone or mood of the writing?
Non-fiction texts are all around us, and comparing them can help you become more aware of how language is being used in society. Comparing non-fiction texts can often prompt you to notice things that you might not have considered about a text in isolation.
Hence the similarities and differences in a non-fiction text look at how the subject or events are portrayed.

What is a dilation?
A dilation is a type of transformation that resizes an object.
To apply a dilation ( find the coordinates of a point after a dilation ) you must multiply the x and y values of the coordinates by the scale factor
Applying the dilation rule
We want to find the coordinate of vertex B after a dilation with a scale factor of 2. To do so we multiply the x and y value of vertex b by the scale factor or 2
Current coordinates of the triangle :
A(1,1) B(1,3)C(3,1)Coordinates after dilation
A' = (1,1) ===> (1×2,1×2) ===> (2,2)
B' = (1,3) ===> (1×2,3×2) ===> (2,6)
C' = (3,1) ===> (3×2,1×2) ===> (6,2)
The coordinate of the vertex B after the dilation is (2,6)
