Quadratic Equations
The standard representation of a quadratic function is:
[tex]f(x)=ax^2+bx+c[/tex]
where a,b, and c are constants.
Solving with the quadratic formula:
[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
The discriminant is defined as:
[tex]d=b^2-4ac[/tex]
The sign of the discriminant defines the nature of the roots of the quadratic equation as follows:
If d is positive, both roots are real and differentIf d is negative, both roots are imaginary and conjugateIf d is zero, both roots are rational and equal.The diameter of a small grain of sand is about 0.00002 meters, which can be written as 2•10^n

What is the equation for this line?
Answers
Answer:
The equation of the line is y = 2x - 3
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
m is the slope of the line, [tex]m=\frac{y2-y1}{x2-x1}[/tex] b is the y-intercept (value y at x = 0)Let us take two points on the line to find its equation
∵ Points (3, 3) and (0, -3) lie on the line
∴ x1 = 3 and y1 = 3
∴ x2 = 0 and y2 = -3
→ Use the rule of the slope above to find m
∵ [tex]m=\frac{-3-3}{0-3}=\frac{-6}{-3}=2[/tex]
∴ m = 2
→ Substitute its value in the form of the equation above
∴ y = 2x + b
∵ b is the value of y at x = 0
∵ y = -3 at x = 0
∴ b = -3
→ Substitute it in the equation above
∴ y = 2x + -3
→ Remember (+)(-) = (-)
∴ y = 2x - 3
∴ The equation of the line is y = 2x - 3

The editor of a textbook publishing company is deciding whether to publish a proposed textbook. Information on previous textbooks published show that 20 %20% are huge successes, 30 %30% are modest successes, 30 %30% break even, and 20 %20% are losers. Before a decision is made, the book will be reviewed. In the past, 99 %99% of the huge successes received favorable reviews, 60 %60% of the moderate successes received favorable reviews, 40 %40% of the break-even books received favorable reviews, and 30 %30% of the losers received favorable reviews. If the textbook receives a favorable review, what is the probability that it will be huge success?
Answers
Answer:
[tex]Probability = 0.198[/tex]
Step-by-step explanation:
Given
Publish
[tex]Huge\ Success = 20\%[/tex]
[tex]Modest\ Success = 30\%[/tex]
[tex]Break\ Even = 30\%[/tex]
[tex]Losers = 20\%[/tex]
Favorable Reviews:
[tex]Huge\ Success = 99\%[/tex]
[tex]Modest\ Success = 60\%[/tex]
[tex]Break\ Even = 40\%[/tex]
[tex]Losers = 30\%[/tex]
Required
Determine the probability that a textbook is huge success and favorable
To do this, we simply multiply the probability of a textbook being huge success and being favorably reviewed. as follows;
[tex]Probability = 20\% * 99\%[/tex]

The 6th graders brought in 56 boxes of tissues 48 pads of loose leaf and 16 rolls of toilet paper. The t acher wants to divide the materials into the greatest amount of containers but wants each container to look the same how many containers can they fill how many of each item will be inside the containers
Answers
Answer:
The greatest amount of containers with each container to looking the same is 8 containers.
Step-by-step explanation:
We have:
56 boxes of tissues
48 pads of loose leaf
16 rolls of toilet paper.
To find the greatest amount of containers with each container to looking the same we apply the greatest common factor method
Step 1
We list the factors of 16, 48 and 56
The factors of 16 are: 1, 2, 4, 8, 16
The factors of 48 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
The factors of 56 are: 1, 2, 4, 7, 8, 14, 28, 56
The greatest common factor is 8.
Hence, the greatest amount of containers with each container to looking the same is 8 containers.

(x,y) → (x + 6, y - 6); (1, -5)
(x, y) + (x + 6, y + 6); (1,7)
Answers
Answer:
B. (x, y) (x - 6, y - 6); (-11,-5)
Step-by-step explanation:
Given the vertices of a rectangle are R(-5, -5), S(-1,-5), 7(-1, 1), and U(-5, 1). After translation, the coordinate R' is at the point (-11, -11), in order to know the translation factors used;
Let (x, y) be the translation coordinate added to the original coordinate R to get R'. To get the coordinate (x, y)
(x, y)+(-5, -5) =(-11, -11)
x - 5 = -11
x = -11+5
x = -6
Similarly;
y-5 = -11
y = -11+5
y = -6
Hence the coordinates added to initial vertices is (-6, -6)
To get the new coordinate U' after translation, we will add the coordinate (-6, -6) to the U(-5, 1) as shown;
(x, y) + (-5, 1) = (-6, -6)+(-5, 1)
= (-6-5, -6+1)
= (-11, -5)
Hence the coordinates of U' is (-11, -5) and the translation rule is (- 6+ x, -6+y) where (x, y) is (-6, -6).
Based on the above calculation, it can be seen that (x, y) (x - 6, y - 6); (-11,-5) is correct.
