x1=-(6/2)+√((6/2)²-6)= -3+√(3) or ≈ -1.267
x2=-(6/2)+√((6/2)²-6)= -3-√(3) or ≈ -4.732
The roots of the quadratic equation, x² + 6x = - 6 are between - 2 and - 1,
and 1 and 2.
What is a quadratic equaton?A quadratic equation is an algebraic expression in the form of variables and constants.
A quadratic equation has two roots as its degree is two.
Given, x² + 6x = - 6.
We know in ax² + bx + c = 0, x = ± √(b² - ac)/2a.
∴ x² + 6x + 6 = 0.
x = ± √(36 - 24)/2×1.
x = ± √(12)/2.
x = ± (2√3)/2.
x = ± √3.
We know √3 is between 1 and 2 and - √3 is between - 2 and - 1.

A store pays $ 56 for a cell phone. The store marks the price at 20%. What is the quantity of the mark?
Answer:
The quantity of the mark is $11.20
Step-by-step explanation:
Given that:
Amount paid by store for cell phone = $56
The store marks the price at 20%.
Quantity of the mark = 20% of 56
Quantity of the mark = [tex]\frac{20}{100}*56[/tex]
Quantity of the mark = 0.2 * 56
Quantity of the mark = $11.20
Hence,
The quantity of the mark is $11.20
Factor out the coefficient of the variable -3.6m + 10.8
Answer: -1
Step-by-step explanation: First, factor out 3.6. You should get -m+3. Since the coefficient is just the number being multiplied to the variable (which is m here), your coefficient should be -1 because m is being multiplied to -1 to make -m. Hope this helps!

What is the EP unit cost of bell pepper if the AP unit cost is 1.10 per pound and the yield percent is 85%?
Answer:
1.30
Step-by-step explanation:
The formula for EP cost is given as:
EP cost = AP cost / yield
From the Question,
AP unit cost = 1.10 per pound
The yield percent = 85%
EP cost = 1.10/85%
EP cost = 1.2941176471
Approximately
The EP unit cost of bell pepper = 1.30

How much interest will you earn on a $90 investment at an interest rate of 3.6% over 5 months?
Answer:
well ik Yearly it would be 93$ and monthly it would be 93$
Step-by-step explanation:
It is important to remember that these scenarios are hypothetical and that future rates of return can't be predicted with certainty and that investments that pay higher rates of return are generally subject to higher risk and volatility. The actual rate of return on investments can vary widely over time, especially for long-term investments. This includes the potential loss of principal on your investment. It is not possible to invest directly in an index and the compounded rate of return noted above does not reflect sales charges and other fees that investment funds and/or investment companies may charge.

What is the volume of a cylinder?The volume of the cylinder is the product of the height, pie, and square of the radius.
The volume of the cylinder = [tex]\pi r^{2} h[/tex]
A.
a) The height of the cylinder is given as 11 in and the radius is 6 in.
So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]
= 3.14 x 6^2 x 11
= 1244.07cubics in
b) The height of the cylinder is given as 30 in and the radius is 24 in.
So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]
= 3.14 x 24^2 x 30
= 54286.72 cubics in
c) The height of the cylinder is given as 21 in.
The radius of the base of the cylinder is given as 19 in.
So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]
= 3.14 x 19^2 x 21
= 23816.41 cubics in
B.
d) The height of the cylinder is 9ft the radius is 3 ft.
So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]
= 3.14 x 3^2 x 9
= 254.47 cubics ft
e) The height of the cylinder is 8 ft the radius is 13 ft.
So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]
= 3.14 x 13^2 x 8
= 4247.43 cubics ft
f) The height of the cylinder is 27 ft the radius is 16 ft.
So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]
= 3.14 x 16^2 x 27
= 21714.69 cubics ft
g) The height of the cylinder is 15 ft the radius is 10 ft.
So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]
= 3.14 x 10^2 x 15
= 4712.39 cubics ft

What is x if n≠m? Please help!
Answer: [tex]x = \frac{mn(q - p)}{n-m}\\\\[/tex]
================================================
Work Shown:
Part 1
[tex]\frac{x-m}{m} + p = \frac{x-n}{n} + q\\\\\frac{x-m}{m} - \frac{x-n}{n} = q - p\\\\\frac{n(x-m)}{mn} - \frac{m(x-n)}{mn} = q - p\\\\\frac{xn-mn}{mn} - \frac{xm-mn}{mn} = q - p\\\\\frac{xn-mn-(xm-mn)}{mn} = q - p\\\\[/tex]
Part 2
[tex]\frac{xn-mn-xm+mn}{mn} = q - p\\\\\frac{xn-xm}{mn} = q - p\\\\\frac{x(n-m)}{mn} = q - p\\\\x(n-m) = mn(q - p)\\\\x = \frac{mn(q - p)}{n-m} \\\\[/tex]
-------------------------------
Explanations:
There are quite a bit of steps. I decided to break things into two parts.The goal is to get x all by itself on its own side, which is why I subtracted (x-n)/n from both sides in part 1, step 2. I also subtracted p from both sides.Afterward, I gave each fraction the LCD mn. I multiplied top and bottom of the first fraction by n/n. I did a similar operation to the second fraction, but with m instead.From there, we distribute and simplify. The mn terms cancel on the left side numerator (second step of part 2).The n≠m is there to prevent the denominator (n-m) from being zero. We cannot divide by zero.

en un auditorio de un pueblo hubo 600 personas en un evento, en total se recaudaron 13 mil pesos. el precio de admision fue 25 pesos para los adultos y 15 pesos para los niños. plantea un sistema de ecuaciones que represente los sucedido
Answer:
There were 200 children and 400 adults in the auditorium.
Step-by-step explanation:
Given that there were a total of 600 peoples in the event.
Let there were n children in the event.
So, the number of an adult in the event = 600-n
As the admission price for one child = 15 pesos
and the admission price for one adult = 25 pesos.
So, total admission price = 15n+25(600-n)
As total money raised = 13000 pesos
So, 15n+25(600-n)=13000
15n+15000-25n=13000
10n=15000-13000=2000
n=2000/10=200
Therefore, number of children = 200
and the number of adults = 600-200=400.
Hence, there were 200 children and 400 adults in the auditorium.

The range of f(x) = |x| is y ≥ 0. If a < 0 and b ≠ 0 for g(x) = a|x| + b, what is the range of function g?
The required range of the function g(x) = a|x| + b is y ≥ 0.
Let's analyze the function g(x) = a|x| + b step by step to determine its range.
The function |x| represents the absolute value of x, which means it always yields non-negative values. Therefore, a|x| will also be non-negative for any value of x.
Adding b to a non-negative value will shift the entire range up by b units, but it will still be non-negative.
Since a < 0, a|x| will be negative when x is positive. However, the absolute value function ensures that it will be positive when x is negative, balancing out the effect.
Finally, adding the constant term b to a|x| makes the entire range of g(x) non-negative.
In summary, the range of g(x) = a|x| + b is y ≥ 0.
