urine completed the square to solve the equation 0 = 3x to the square root of 2 - 9x + 27
Yes, Urie correctly completed the square to solve the equation 0 = 3x + 9 to the square root of 2 - 9x + 27.
How to solve square root equation? A square root equation is an equation that contains a square root of a variable, typically represented by the radical symbol √. To solve a square root equation, you must isolate the radical symbol on one side of the equation and then square both sides of the equation.For example, if the equation is √x + 3 = 7, you would need to subtract 3 from both sides to isolate the radical symbol on the left side of the equation. This would give you √x = 4. Then, square both sides of the equation to get rid of the radical symbol. This would give you x = 16, which is the solution to the equation.In general, to solve a square root equation, you must first isolate the radical symbol on one side of the equation. Then, square both sides of the equation to get rid of the radical symbol, which will give you the solution to the equation. It is important to remember to always square both sides of the equation, so that the equation is still balanced after the radical symbol is removed.To learn more about square root of equation refer to:

What are the zeros of quadratic function 2x² 7x 3?
The zeros of quadratic function 2x² - 7x + 3 = 0 are 3 and 1/2.
There are several methods for solving a quadratic equation of the form ax² + bx + c = 0. In our case, use the quadratic formula x = (-b ± √(b² - 4ac)) / 2a to find the zeros or the solutions for x.
Plug in the values to the formula and solve for x.
x = (-b ± √(b² - 4ac)) / 2a
x = (--7 ± √(-7² - 4(2)(3))) / 2(2)
x = (7 ± √49 - 24) / 4
x = (7 ± √25) / 4
x = (7 ± 5) / 4
x = 3 ; x = 1/2
Hence, the zeros of quadratic function 2x² - 7x + 3 = 0 are 3 and 1/2.

A population of field mice is 120. The population increas es at a rate of 9% a year. Write an exponential function that models
this situation:
Answer:
Population(year x) = 120*(1.09)^x
Step-by-step explanation:
Let x be the number of years from the time the population is 120 (year 0).
Population(year x) = 120*(1.09)^x
The 1.09 represents the growth for 1 year added to the initial population. E.g., year 1 would have a population of 120*(1.09)^1 or 140.8 (141). Year 2 would be 120*(1.09)^2 or 142.5 (143). And so on.
Each new year bilds on the prior year's ending population. In longhamd, this would be:
Year Pop.
0 120 120*(1.09)^0
1 141 120*(1.09)
2 120*(1.09)(1.09) or 120*(1.09)^2
3 120*(1.09)(1.09)(1.09) or 120*(1.09)^3

The perimeter of a rectangle is 172 feet. Find the length and width if the length is an integer and the width is 2 times the next consecutive integer.
The length and width of the rectangle is 28 feet and 58 feet respectively.
How to find the sides of a rectangle?A rectangle is a quadrilateral with opposite sides equal to each other and opposite sides parallel to each other.
Therefore, the perimeter of a rectangle is the sum of the whole 4 sides of the rectangle.
Hence, the perimeter of a rectangle is 172 feet.
perimeter of a rectangle = 2(l + w)
where
l = lengthw = widthl = x
w = 2(x + 1) = 2x + 2
Therefore,
172 = 2(x + 2x + 2)
172 = 2(3x + 2)
divide both sides by 2
172 / 2 = 3x + 2
86 = 3x + 2
86 - 2 = 3x
3x = 84
divide both sides by 3
x = 84 / 3
x = 28
Therefore,
length = 28 feet
width = 2(28) + 2 = 58 feet

Rewrite g (x) = 3^-x when x = 7/5. Write this as an expression with a positive rational exponent and as an expression involving a radical. Show where g (7/5) would be located on the graph.
Step-by-step explanation:
g(x) = 3^-x
x = 7/5
so,
3^-(7/5)
the "-" says "1/...", therefore
1/(3^(7/5))
that is the expressing with the positive rational exponent.
with a fractional a/b exponent, "a" means "to the power of", and "b" means "pull the bth root".
so,
1/(3^(7/5)) =
[tex] \frac{1}{ \sqrt[5]{ {3}^{7} } } [/tex]
that is the expression with a radical.
to find the point find the origin (0, 0) point. from there go eighth on the x-axis to 7/5 = 1.4. and from there you go straight up to the curve. that is the point of g(7/5).
1/(3^(7/5)) = 0.214798005...
that is what the y value would be of that point.

Logarithmic equations with negative logs have no solution. Always use the original logarithmic equation to check for solved values.
What are the rules of Logarithms?The rules apply to any logarithm logbx, with the exception that any occurrence of e must be replaced with the new base b. Equations (1) and (2) defined the natural log. It is acceptable for x to be 0 or negative. However, when substituted or evaluated into the original logarithm equation, it is not allowed to have a logarithm of a negative number or a logarithm of zero, 0.
If we solve for x using log rules and properties, then plug those x values into the original equation, the equation should be satisfied. Also, keep in mind that the log's argument after plugging in the x values must be positive. There is no solution because the log's argument is negative.

How do I know if my cervix is dilating?
Knowing if your cervix is dilating typically involves a physical examination by a healthcare provider.
During labor, a healthcare provider will check the dilation of your cervix by performing a pelvic exam. They will use their fingers to feel the cervix, which is located at the top of the vagina, and determine the degree of dilation.
Cervical dilation is measured in centimeters, and full dilation is considered to be 10 centimeters. Before labor begins, the cervix is typically closed and has a firm consistency. As labor progresses, the cervix will start to soften and thin out, and will eventually open, or dilate.
Some women might experience Braxton Hicks contractions, which are sometimes referred as "false contractions" as they can be mistaken for the start of labor, but Braxton Hicks contractions do not cause cervical dilation.
It's important to note that dilation is just one of the factors that indicate that labor is imminent. It is not the only factor and some women can have a fully dilated cervix for days before going into active labor.
In conclusion, knowing if your cervix is dilating typically involves a physical examination by a healthcare provider, who will perform a pelvic exam to feel the cervix and determine the degree of dilation.
Cervical dilation is measured in centimeters, with full dilation being 10 centimeters. Be aware that dilation is just one of the factors that indicate labor is imminent.

The slope of the given equation y = -5x is -5.
The equation y = -5x is a linear equation, which means that it is a function that can be represented in the form y = mx + b, where m is the slope and b is the y-intercept. The slope of a linear equation is the coefficient of x in the equation. In this case, the coefficient of x is -5, so the slope of the equation is -5.
It's worth noting that the slope represents the rate of change of the y-coordinate with respect to the x-coordinate, in other words, the steepness of the line. A slope of -5 means that for each unit increase in the x-coordinate, the y-coordinate will decrease by 5 units.
