Solving Equation with Root and Power. Can someone please step by step explain how to solve this problem please?
Answers
Answer:
[tex]x=1[/tex]
Step-by-step explanation:
First, square both sides.
[tex]\left(\sqrt{3+\dfrac{\left(4 + \sqrt{x+3} \, \right)^2}{6}}\, \right)^2= 3^2[/tex]
[tex]3+\dfrac{\left(4 + \sqrt{x+3} \, \right)^2}{6} = 9[/tex]
This eliminates the square root over the entire left side of the equation.
Next, multiply both sides by 6 to get rid of the fraction on the left side.
[tex]6\left(3+\dfrac{\left(4 + \sqrt{x+3} \, \right)^2}{6}\right) = 6( 9)[/tex]
[tex]6(3) + \left(4 + \sqrt{x+3} \, \right)^2 = 6(9)[/tex]
[tex]18 + \left(4 + \sqrt{x+3} \, \right)^2 = 54[/tex]
Then, subtract 18 from both sides to isolate the squared term.
[tex]18 + \left(4 + \sqrt{x+3} \, \right)^2 = 54\\\underline{-18 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \: } \ \ \ \ \ \underline{ - 18}[/tex]
[tex]\left(4 + \sqrt{x+3} \, \right)^2 = 36[/tex]
Now, we can square root both sides.
[tex]\sqrt{\left(4 + \sqrt{x+3} \, \right)^2} = \sqrt{36}[/tex]
[tex]4 + \sqrt{x+3} = \pm 6[/tex]
Remember to use apply the even root property, so that the right side (6) is positive or negative (indicated by the plus or minus sign).
Next, subtract 4 from both sides.
[tex]4 + \sqrt{x+3} = \pm 6 \\ \underline{-4\ \ \ \ \ \ \ \ \ \ \: } \ \ \ \ \ \underline{ - 4}[/tex]
[tex]\sqrt{x+3} = \pm 6 - 4[/tex]
Then, square both sides to get rid of the square root on the left side.
[tex]\left(\sqrt{x+3}\right)^2 = (\pm 6 - 4)^2[/tex]
[tex]x+3 = 2^2[/tex] OR [tex]x+3 = (-10)^2[/tex]
We can see that there are two resulting expressions, each of which we can solve individually.
[tex]x+3 = 4[/tex] OR [tex]x+3 = 100[/tex]
[tex]\boxed{x = 1}[/tex] [tex]\boxed{x\ne97}[/tex]
The reason that x = 97 is crossed out is because when we plug that x-value back into the original equation, it does not come out to be true. Therefore, 97 is an extraneous solution.
Also, see the attached image for another solution (that implores another method).
Answer:
x = 1
Step-by-step explanation:
You want to solve for x:
[tex]\sqrt{3+\dfrac{(4+\sqrt{x+3})^2}{6}}=3[/tex]
SolutionAt any stage where there is a root, you isolate the radical and raise both sides of the equation to a power sufficient to eliminate the radical. Repeat as necessary.
Outer radicalThe radical is already on one side of the equation by itself, so we simply square both sides:
[tex]3+\dfrac{(4+\sqrt{x+3})^2}{6}=9\\\\(4+\sqrt{x+3})^2=6^2\qquad\text{subtract 3, multiply by 6}\\\\|4+\sqrt{x+3}|=6\qquad\text{take the square root}[/tex]
Inner radicalAt this point, we note that the sum cannot be negative, so the absolute value bars are irrelevant. Isolating the radical and squaring both sides, we can finish the solution.
[tex]4+\sqrt{x+3}=6\\\\\sqrt{x+3}=2\qquad\text{subtract 4}\\\\x+3=4\qquad\text{square both sides}\\\\\boxed{x=1}\qquad\text{subtract 3}[/tex]
This is the only solution, as the attached graph shows.

Additional comment
Generally, the square root symbol means the positive square root. That is, √z is usually considered to be non-negative. This is why we use ±√z when we want both signs of the root.
In this problem, the only root we're taking as part of the solution is the root of a square. The possibility of a negative value for the term being squared is handled by using the absolute value brackets: √(z²) = |z|.
For solving these using a graphing calculator, we like to rewrite the equation to the form f(x)=0. That way, the solutions are the x-intercepts.

An aquarium can be modeled as a right rectangular prism and it can hold 1120 cubic inches of water when it is full. Its length is 20 in and width is 8 in. Find the height of the aquarium in inches. Round your answer to the nearest tenth if necessary.
Answers
The height of the right rectangular prism aquarium is 7 inches
How to determine the height of the aquariumWe can use the formula for the volume of a right rectangular prism to find the height of the aquarium.
The formula is V = l x w x h,
Where V is the volume, l is the length, w is the width, and h is the height.
In this case, we know that the volume of the aquarium is 1120 cubic inches, the length is 20 inches, and the width is 8 inches.
Therefore, we can write:
1120 = 20 x 8 x h
Simplifying the right side of the equation, we get:
1120 = 160h
Dividing both sides by 160, we obtain:
h = 1120/160 = 7
Therefore, the height of the aquarium is 7 inches.

What is mean in statistics?
In statistics, the mean is a measure of central tendency, which represents the average value of a set of numbers. It is calculated by adding up all the values in the data set and dividing the sum by the number of values. The mean is also called the arithmetic mean or the average. It is commonly used to describe the typical value of a group of numbers.
To determine which statement is supported by the data, we need to analyze the weights of the fish that Terri and her father caught. Here are some possible statements that could be supported by the data:
A. The average weight of the fish caught was less than 7 pounds.
B. The heaviest fish caught weighed more than 12 pounds.
C. The total weight of the fish caught was more than 60 pounds.
D. The range of weights of the fish caught was between 4 and 12 pounds.
To determine which statement is supported, we can calculate some basic statistics:
Mean (average) weight: (5.6 + 11.0 + 4.0 + 12.2 + 7.0 + 10.0 + 4.2) / 7 = 7.8 pounds
Maximum weight: 12.2 pounds
Minimum weight: 4.0 pounds
Range of weights: 12.2 - 4.0 = 8.2 pounds
Total weight: 5.6 + 11.0 + 4.0 + 12.2 + 7.0 + 10.0 + 4.2 = 54 pounds
Based on this analysis, we can see that statement C ("The total weight of the fish caught was more than 60 pounds") is not supported by the data, as the total weight was only 54 pounds.
Statement A ("The average weight of the fish caught was less than 7 pounds") is also not supported, as the average weight was 7.8 pounds.
Statement B ("The heaviest fish caught weighed more than 12 pounds") is supported, as the heaviest fish weighed 12.2 pounds.
Finally, statement D ("The range of weights of the fish caught was between 4 and 12 pounds") is also supported, as the weights ranged from 4.0 to 12.2 pounds.
Therefore, the correct answer is either B or D, depending on the context of the question.

If - 3y = 1 and 11y - x = -5, then what does x - 10y = ?
Answers
The answer for x - 10y = 14/3.
Solving for x and y by substitution methodTo solve for x and y, we can use the first equation to solve for y in terms of x:
-3y = 1
y = -1/3
Now we can substitute this value of y into the second equation and solve for x:
11y - x = -5
11(-1/3) - x = -5
-x = -5 + 11/3
-x = -4/3
x = 4/3
Now that we have found the values of x and y, we can substitute them into the expression x - 10y:
x - 10y = (4/3) - 10(-1/3)
x - 10y = 4/3 + 10/3
x - 10y = 14/3

The sink is completely full when Carissa begins scooping. One cup has a diameter of 6 in. and a height of 14 in. How many cups of water must Carissa scoop out of the sink with this cup to empty it? Round the number of scoops to the nearest whole number. One cup has a diameter of 10 in. and a height of 12 in. How many cups of water must she scoop out of the sink with this cup to empty it? Round the number of scoops to the nearest whole number. Answer:
Answers
By taking the quotient between the volume of the sink and the volume for each cone, we will see that both of your answers are correct.
How many coops does Carissa need to scoop out in each case?
First, we know that the sink has a volume V = (2000/3)*pi in^3
A) First she uses a cone of a diameter of 4 in and a height of 8 in.
Remember that the volume of a cone of diameter D and height H is:
V = pi*(D/2)^2*H/3
Then this cone has a volume of:
V' = (pi/3)*(4in/2)^2*8in = (pi/3) 32 in^3
The number of scoops needed to completely remove the water out of the sink is given by the quotient between the two volumes, it is:
Rounding it, we get 63, so she needs to scoop 63 times.
B) This time the diameter is 8 in and the height 8 in, so the volume of the cone is:
V'' = (pi/3)*(8in/2)^2*8in = (pi/3)*128 in^3
This time, she needs to scoop:
Rounding to the next number we get 16, she needs to scoop 16 times.
So yes, both of your answers are correct.
l be beneficial both in school and in other parts of your life.[1]
Answer:
Step-by-step explanation:
To determine how many conical cups of water Carissa must scoop out of the half-sphere sink to empty it, divide the volume of the sink by the volume of each cup.
[tex]\boxed{\begin{minipage}{4 cm}\underline{Volume of a cone}\\\\$V=\dfrac{1}{3} \pi r^2 h$\\\\where:\\ \phantom{ww}$\bullet$ $r$ is the radius. \\ \phantom{ww}$\bullet$ $h$ is the height.\\\end{minipage}}[/tex]
To determine the volume of conical cup 1 (in terms of π) given it has a diameter of 6 in and a height of 14 in, substitute r = 3 and h = 14 into the volume of a cone formula:
[tex]\begin{aligned}\implies V_{\sf cup\:1}&=\dfrac{1}{3} \pi (3)^2(14)\\\\&=\dfrac{1}{3} \pi (9)(14)\\\\&=\dfrac{126}{3} \pi\\\\&=42 \pi\;\sf in^3\end{aligned}[/tex]
Divide the given volume of the sink by the volume of conical cup 1 to calculate the number of cups of water Carissa must scoop out of the sink to empty it.
[tex]\begin{aligned}\implies \dfrac{4500}{3}\pi \div 42 \pi &=\dfrac{4500}{3}\pi \times \dfrac{1}{42 \pi}\\\\ &=\dfrac{4500 \pi}{126 \pi}\\\\&=\dfrac{4500}{126}\\\\&=35.7142867...\\\\&=36\;\sf(nearest\;whole\;number)\end{aligned}[/tex]
Therefore, Carissa must scoop out 36 cups of water to empty the sink.
To determine the volume of conical cup 2 (in terms of π) given it has a diameter of 10 in and a height of 12 in, substitute r = 5 and h = 12 into the volume of a cone formula:
[tex]\begin{aligned}\implies V_{\sf cup\:2}&=\dfrac{1}{3} \pi (5)^2(12)\\\\&=\dfrac{1}{3} \pi (25)(12)\\\\&=\dfrac{300}{3} \pi\\\\&=100\pi\;\sf in^3\end{aligned}[/tex]
Divide the given volume of the sink by the volume of conical cup 2 to calculate the number of cups of water Carissa must scoop out of the sink to empty it.
[tex]\begin{aligned}\implies \dfrac{4500}{3}\pi \div 100 \pi &=\dfrac{4500}{3}\pi \times \dfrac{1}{100 \pi}\\\\ &=\dfrac{4500 \pi}{300\pi}\\\\&=\dfrac{4500}{300}\\\\&=15\end{aligned}[/tex]
Therefore, Carissa must scoop out 15 cups of water to empty the sink.

Whats the easiest way to solve "two unit multipliers"?
Answers
The easiest way to solve problems involving "two unit multipliers" is to use a technique called unit conversion or dimensional analysis.
To solve such problems, you need to convert the given value from one unit to another by multiplying it by a series of conversion factors or unit multipliers. A conversion factor is a fraction that has the same value as one, but its numerator and denominator are expressed in different units.
For example, to convert 10 meters to feet, you can use the conversion factor:
1 meter = 3.28 feet
To convert 10 meters to feet, you would multiply 10 by the conversion factor:
10 meters * (3.28 feet/1 meter) = 32.8 feet
The meters unit cancels out, leaving you with the desired unit of feet.
In some cases, you may need to use multiple conversion factors to get from one unit to another. In these cases, you can multiply or divide the conversion factors to cancel out the unwanted units until you get to the desired unit.
Using unit conversion or dimensional analysis is an effective way to solve problems involving two unit multipliers because it ensures that the units cancel out correctly, and you end up with the desired unit in your final answer.

If the model is 18 inches long and the actual locomotive is 72 feet long, what is the similarity transformation to map from the model to the actual locomotive? Express the answer using the notation x* ax, where x is a measurement on the model and ax is the corresponding measurement on the actual locomotive.
Answers
Answer:
(1/48)ax
Step-by-step explanation:
We can use the proportion of the lengths of the model and the actual locomotive to determine the scale factor for this similarity transformation.
The model is 18 inches long, which is equivalent to 1.5 feet (since 1 foot = 12 inches). The actual locomotive is 72 feet long. So, the scale factor can be calculated as:
scale factor = actual length / model length
scale factor = 72 feet / 1.5 feet
scale factor = 48
This means that each measurement on the model is 1/48th the size of the corresponding measurement on the actual locomotive. We can express this similarity transformation using the notation x* ax as: x* (1/48)ax
So, if a measurement on the model is x, the corresponding measurement on the actual locomotive would be (1/48)ax.
Triangle with angles A= 30 degrees mB =60 degrees Mac = 90 degrees which is true
Answers
We have a right triangle with sharp angles measuring 30 and 60 degrees, proving the assertion "Triangle with angles A= 30 degrees, B= 60 degrees, C= 90 degrees" to be true.
How are triangles determined by angles?To assess whether the supplied angles may form a triangle, we can use the knowledge that the total of the angles in a triangle is always 180 degrees. Let's figure up the angles' total:
180 degrees is equal to A + B + C = 30 + 60 + 90.
The supplied angles can definitely form a triangle because the sum of the angles is 180 degrees. We can now utilise the data to identify the kind of triangle.
The angles indicate that a right triangle with a 90-degree angle (angle C) and acute angles of 30 degrees and 60 degrees (angles A and B) exists (angle B).
The measurements of angles A and B are compatible with the available information since the total of the acute angles in a right triangle is always 90 degrees.

x = -3 -> 3 units to the left of the y-axis.x = 1 -> 1 unit to the right of the y-axis.Hence the set containing the roots of the graphed quadratic function is given as follows:
{-3, 1}

Does it really matter if a person keeps failing math tests or is known to not be good in maths? how does that affect him/her?
Answers
Answer: It doesn't really matter
Step-by-step explanation: This is more of an opinion question, but failing math tests doesn't mean you aren't good at math, some people have different reasons why they don't try at math. Math tests don't define how good or bad you really are in math. You can fail a math test and be good at math, but not passing math tests might also create a lot of issues in the careers you're trying to persuade in because math is one of the most useful subjects. If colleges see your math scores and how badly you performed in them, they won't pick you, which is why is always nice to try no matter how easy or hard it is.

Explain about the traversal of parallel line?When a transversal divides two parallel lines, the resulting alternate interior angles are congruent.
The pairs of angles from outside two lines and on either side of a transversal that cuts two lines are referred to as the alternate external angles.Lines that never intersect and always remain the exact same distance apart are said to be parallel. A line that crosses 2 or more additional lines is referred to as a transversal.Alternative External Angles are congruent if a transversal cuts two parallel lines. When a transversal cuts two parallel lines, the resulting angles are congruent.Thus, m∠5 + m∠2 = m∠3 + m∠2, is the missing statement in step 4.

The experimental probability of choosing a nickel based on 13 trials would be 4 / 13
How to find the experimental probability ?The experimental probability can be found by the formula ;
= ( ( Probability of picking a Nickel x Number of trials ) + 1 ) / 13 trials
Probability of picking a Nickel - 1 / 4
Number of trials - 13 trials
The experimental probability for Landon picking a Nickel on the 13th trial is :
= ( ( 1 / 4 x 12 ) + 1 ) / 13
= ( 3 + 1 ) / 13
= 4 / 13
