Solving Square Root Equations
Solve the following equations. Be sure to label any extraneous solutions.
Answers
Answer:
Step-by-step explanation:
1) To solve the equation √(6x) = x, we can first square both sides of the equation to eliminate the square root:
(√(6x))^2 = x^2
6x = x^2
Next, we can rearrange the equation into standard quadratic form by subtracting 6x from both sides:
x^2 - 6x = 0
Now, we can factor out an x from the left-hand side of the equation:
x(x - 6) = 0
Setting each factor equal to zero, we find two solutions:
x = 0 or x - 6 = 0
Therefore, the solutions to the equation √(6x) = x are x = 0 and x = 6.
2)To solve √(5x-6) = x, we can square both sides of the equation:
(√(5x-6))^2 = x^2
5x-6 = x^2
Rearranging this quadratic equation to the standard form ax^2 + bx + c = 0, we get:
x^2 - 5x + 6 = 0
This can be factored into:
(x - 2)(x - 3) = 0
Therefore, the solutions to the equation √(5x-6) = x are x = 2 and x = 3.
We should check if these solutions satisfy the original equation:
When x=2: √(5x-6) = √(5(2)-6) = √4 = 2, which satisfies the equation.
When x=3: √(5x-6) = √(5(3)-6) = √9 = 3, which also satisfies the equation.
Therefore, the solutions are x = 2 and x = 3.
3) To solve the equation √(2x-1) = x-3, we can square both sides of the equation to eliminate the square root:
(√(2x-1))^2 = (x-3)^2
Simplifying the left-hand side gives:
2x-1 = (x-3)^2
Expanding the right-hand side gives:
2x-1 = x^2 - 6x + 9
Rearranging the equation gives:
x^2 - 8x + 10 = 0
We can solve this quadratic equation :
x^2 - 8x + 10 = 0
Now we can solve this quadratic equation by using the quadratic formula:
x = (-b ± √(b^2 - 4ac)) / 2a
In this case, a = 1, b = -8, and c = 10. Substituting these values into the formula:
x = (-(-8) ± √((-8)^2 - 4(1)(10))) / 2(1)
Simplifying:
x = (8 ± √(64 - 40)) / 2
x = (8 ± √24) / 2
x = 4 ± √6
Therefore, the solutions to the equation √(2x - 1) = x - 3 are x = 4 + √6 and x = 4 - √6.
4) has no real solutions.
when you have to remove the square root you have to power the both sides of the equation.
1)6x= x^2
0 = x^2 - 6x
0= x(x-6)
x=0 or x-6=0
x=6
2) \(\sqrt{5x-6}\) = x
5x-6=x^2
x^2 -5x+6=0
(x-3)(x-2)=0
x-3=0 or x-2= 0
x=3 or x=2
3)
\(\sqrt{2x-1}\) = x-3
2x-1 = (x-3)^2
2x-1= x^2 - 6x +9
x^2 -8x +10=0
this equation can't solve by factoring method easily. so we have to use the completing square method.
x^2-8x+10=0
x^2-8x= -10
x^2 - 8x+(-4)^2 = -10+ ( -4)^2
(x-4)^2 = 6
\(x= 4 +\sqrt{6}\) or \(x= 4 -\sqrt{6}\)
4) \(x= 2 + \sqrt{2x-11}\)
x^2= 4+4 \(\sqrt{2x-11}\) + 2x-11
x^2= 7+ 2x +4\(\sqrt{2x-11}\)
x^2-2x-7= 4\(\sqrt{2x-11}\)
(x^2-2x-7)^2= 16 (2x-11)
x^4 +4x^2 +49-4x^3 + 28x - 14x^2 = 32x-176
x^4 - 4x^3 - 10x^2 - 4x + 225= 0
x(x^3 -4x^2 - 10x-4)+225=0
this is a power 4 th equation this equation can solve by normal steps.

veronica is making a large table in the shape of a trapezoid. she needs to calculate the area of the table she is making the longest side
Answers
1. We can see that the number in the bottom box is: 13.5yd.
2. The number in the top box is: 7.5yd.
3. The area of the table = 78.75yd²
What is a trapezoid?A trapezoid, also known as a trapezium in some countries, is a quadrilateral shape that has only one pair of parallel sides. The parallel sides of a trapezoid are called the bases of the trapezoid, and the non-parallel sides are called the legs.
We see here that in order to get the number in the bottom box, we discover that the number in the top box is a square which means that all the sides are equal to 7.5yd.
Thus, the number in the bottom box = 3 + 7.5 + 3 = 13.5yd.
Thus, the area of the table, a trapezoid = 1/2(a + b)h
Where a = 7.5yd
b = 13.5yd
height, h = 7.5yd.
Thus, A = 1/2(7.5 + 13.5) 7.5 = 157.5/2 = 78.75
∴ Area of the table, A = 78.75yd²

The length of a rectangular poster is 2 more inches than two times its width. The area of the poster is 84 square inches. Solve for the dimensions (length and width) of the poster.
Answers
Step-by-step explanation:
w = width
2w + 2 = Length
Area = W x L = 84 = w (2w+2)
84 = 2w^2 + 2w

a = 2 b=2 c = -84
to find
W = 6 then L = 14 inches
In circle O, secants ADB and AEC are drawn from external point A
such that points D, B, E, and C are on circle O. If AD = 8, AE = 6,
and EC is 12 more than BD, the length of BD is
(1) 6
(2) 22
(3) 36
(4) 48
Answers
The length of BD is 22.
In the given scenario, let's consider the following information.
AD = 8
AE = 6
EC is 12 more than BD.
To find the length of BD, we can utilize the Intercepted Arcs Theorem, which states that when two secants intersect outside a circle, the measure of an intercepted arc formed by those secants is equal to half the difference of the measures of the intercepted angles.
From the given information, we know that AD = 8 and AE = 6.
Since these are the lengths of the secants, we can use them to calculate the intercepted arcs.
First, let's find the intercepted arc corresponding to AD:
Intercepted Arc ADB = 2 \(\times\) AD = 2 \(\times\) 8 = 16
Similarly, we can find the intercepted arc corresponding to AE:
Intercepted Arc AEC = 2 \(\times\) AE = 2 \(\times\) 6 = 12
Now, we know that EC is 12 more than BD.
Let's assume the length of BD as x.
BD + 12 = EC
Now, let's consider the intercepted arcs theorem:
Intercepted Arc ADB - Intercepted Arc AEC = Intercepted Angle B - Intercepted Angle C
16 - 12 = Angle B - Angle C
4 = Angle B - Angle C.
Since Angle B and Angle C are vertical angles, they are congruent:
Angle B = Angle C.
Therefore, we can say:
4 = Angle B - Angle B
4 = 0
However, we have reached an inconsistency here.
The equation does not hold true, indicating that the given information is not consistent or there may be an error in the problem statement.
As a result, we cannot determine the length of BD based on the given information.

For a 4-unit class like Statistics, students should spend average of 12 hours studying for the class. A survey was done on 25 students, and the distribution of total study hours per week is bell-shaped with a mean of 14 hours and a standard deviation of 2.5 hours. Use the Empirical Rule to answer the following questions. a) 68% of the students spend between hours and hours on Statistics each week. b) 95% of the students spend between hours and hours on Statistics each week. c) 99.7% of the students spend between hours and hours on Statistics each week.
Answers
68% of the students spend between 11.5 and 16.5 hours, 95% of the students spend between 9 and 19 hours, and 99.7% of the students spend between 6.5 and 21.5 hours studying for Statistics each week.
What is the mean and Standard deviation?
Standard deviation is: It is a measure of how spread out numbers are. It is the square root of the Variance, and the Variance is the average of the squared differences from the Mean.
The Empirical Rule states that for a normal distribution, approximately 68% of the data falls within one standard deviation of the mean, approximately 95% falls within two standard deviations of the mean, and approximately 99.7% falls within three standard deviations of the mean.
a) Using the Empirical Rule, we can find the range of hours in which 68% of the students spend studying for Statistics each week:
Mean = 14 hours
Standard deviation = 2.5 hours
One standard deviation from the mean is 14 ± 2.5, so:
14 - 2.5 = 11.5 hours
14 + 2.5 = 16.5 hours
Therefore, 68% of the students spend between 11.5 and 16.5 hours studying for Statistics each week.
b) Using the Empirical Rule, we can find the range of hours in which 95% of the students spend studying for Statistics each week:
Mean = 14 hours
Standard deviation = 2.5 hours
Two standard deviations from the mean is 14 ± 2.5 * 2 = 14 ± 5, so:
14 - 5 = 9 hours
14 + 5 = 19 hours
Therefore, 95% of the students spend between 9 and 19 hours studying for Statistics each week.
c) Using the Empirical Rule, we can find the range of hours in which 99.7% of the students spend studying for Statistics each week:
Mean = 14 hours
Standard deviation = 2.5 hours
Three standard deviations from the mean is 14 ± 2.5 * 3 = 14 ± 7.5, so:
14 - 7.5 = 6.5 hours
14 + 7.5 = 21.5 hours
Therefore, 99.7% of the students spend between 6.5 and 21.5 hours studying for Statistics each week.
Hence, 68% of the students spend between 11.5 and 16.5 hours, 95% of the students spend between 9 and 19 hours, and 99.7% of the students spend between 6.5 and 21.5 hours studying for Statistics each week.

How do you express a data set in interval notations?Interval notation is used to represent continuous intervals of numbers or values, like ranges on a number line.
The graph shows that from 8-9am, and 11-12pm, the cost from Swift Ride decreases.
We can represent it as (8am, 9am) U (11am, 12pm).
It increases at these times (12pm, 1pm) U (1pm, 2pm) U (2pm, 3pm).
And stays constant at : (9am, 10am) U (10am, 11am)
Cost increase from 12 to 3pm,We simply deduct the 12pm's cost from 3pm's cost.
So, we have
Cost increase = $3.5 - $1.5
Evaluate the difference
Cost increase = $2
Hence, the cost increase is $2

determine the longest wavelength photon (in nm) which can remove an electron from mercury metal if the work function of the metal is 4.475 ev (1 ev
Answers
To determine the longest wavelength photon which can remove an electron from mercury metal, we need to use the equation:
wavelength = hc/work function
What are photons?Photons are just light particles. Photons are basic subatomic particles that convey the electromagnetic force (and so much more). The photon is the basic unit of electromagnetic radiation, or the "quantum."
What is wavelength?A waveform signal that is carried in space or down a wire has a wavelength, which is the separation between two identical places (adjacent crests) in the consecutive cycles. This length is often defined in wireless systems in meters (m), centimeters (cm), or millimeters (mm) (mm).
To determine the longest wavelength photon which can remove an electron from mercury metal, you need to use the equation:
wavelength = hc/work function
where h is the Planck constant (6.626 x 10^-34 Js), c is the speed of light (2.998 x 10^8 m/s), and work function is the minimum energy needed to remove an electron from the metal, in this case 4.475 eV.
Plugging these values into the equation gives:
wavelength = (6.626 x 10^-34 Js)(2.998 x 10^8 m/s)/(4.475 x 1.602 x 10^-19 J/eV)
This simplifies to:
wavelength = 404.4 nm
So, the longest wavelength photon which can remove an electron from mercury metal is 404.4 nm.
