Find the derivative of [tex]\frac{dy}{dx}[/tex] to get [tex]\frac{d^2y}{dx^2}[/tex] .
4[tex]\sqrt{y^2+7x^2}[/tex] = 4([tex]y^{2}[/tex]+7[tex]x^{2}[/tex])^1/2
[tex]\frac{d^2y}{dx^2}[/tex] = 4(1/2)([tex]y^{2}[/tex]+7[tex]x^{2}[/tex])^-1/2 * (2y[tex]\frac{dy}{dx}[/tex] +14x)
Plug in x=1 and y=3.
2(9+7)^-1/2 * (6[tex]\frac{dy}{dx}[/tex] +14)
2(1/4) * (6[tex]\frac{dy}{dx}[/tex] +14)
(1/2) (6[tex]\frac{dy}{dx}[/tex] +14)
3[tex]\frac{dy}{dx}[/tex] +7
Plug in [tex]\frac{dy}{dx}[/tex].
3(4[tex]\sqrt{y^2+7x^2}[/tex] ) +7
Plug in x=1 and y=3.
3(4[tex]\sqrt{9+7}[/tex] ) +7
3(4[tex]\sqrt{16}[/tex] ) +7

Select the two recommendations that would decrease the margin of error of the interval.
From the options given, the only option which would result on having a reduced error margin, is to increase the sample size.
Recall :
Margin of Error = Zcritical × σ/√n
Increasing the mean would have no impact on the margin of error as it is not a part of the factors which affects the margin of error value. Increasing the standard deviation, which is the Numerator will result in an increased margin of error value. By raising the confidence level, the critical value of Z will increase, hence widening the margin of error. The sample size, n being the denominator, would reduce the value of error margin.Hence, only the sample size will cause a decrease in the margin of error of the interval.

A story with multiple narrators will usually have a(n) ____________ plot.
Answer:
nonlinear
Explanation:
It has become increasingly popular in young adult novels to have
multiple narrators. Often, this is done through alternating
chapters. One chapter is told from one perspective, while the
next chapter is told from another. This can be done with either
first person or third person limited.
Multiple Narrators
This will likely mean that the plot is nonlinear in such a novel. The
reader will jump from one character and event to another (and
sometimes even see the same event twice, but from different
perspectives).
This is also sometimes called "alternating point of view".
Stories could either have a single or multiple narrator(s). Hence, stories having multiple narrators would usually have a non-linear plot.
Multiple narrators in a story means that characters in the story are numerous, hence, acts and scenes would have to be passed on to these characters from time to time. As for single narrator, this is not the case as the number of actors are very limited.Hence, because multiple narrators often hinders a story to be chronologically ordered, then it would result in a non-linear plot.

Which of the following devices is used in this experiment to separate the different wavelengths emitted by the light source?.
A spectrometer employs diffraction to divide light into a spectrum, which is a collection of wavelengths.
What different wavelengths emitted by the light source?A light source beam's wavelengths are spectrally isolated using monochromators. A monochromator separates poly chromatic light into a variety of distinct wavelengths.
The most common application of a spectrometer is to measure the wavelengths of electromagnetic radiation (light) that have interacted with a sample.
A sample may reflect, absorb, or transmit incident light; the way the incident light changes as it interacts with the sample is a characteristic of the sample.
When calculating the concentration of a colored solution, the wavelength of maximum absorbance is used because at this wavelength even a small change in concentration can result in a large change in light absorption.
Therefore, spectrometer devices are used in this experiment to separate the different wavelengths emitted by the light source.

On january 1, 2019, a company issued $400,000 of 10-year, 12% bonds. The interest is payable semi-annually on june 30 and december 31. The issue price was $413,153 based on a 10% market interest rate. The effective-interest method of amortization is used. What is the book value (carrying value) of the bond liability as of june 30, 2019 (to the nearest dollar)?.
The book value of the bond liability is $409811
First of all we have to calculate the cash that was paid for interest
This interest is payable semiannually that is 6 months out of 12 months
6/12 = 0.5
The bond is 12% = 0.12
= 400000 * 0.12 * 0.5
= 24000 dollars
The interest =
413153 * 10% * 0.5
= 20658 dollars
The reduction = 24000-20658
= 3342 dollars
The carrying value after the first payment
= 413153-3342
= $409811
The book value of the bond liability is $409811

Which of the following best describes the process of translation?.
Answer:
Translation is a universal process in biology where a protein formed of amino acids is made by using messenger Ribonucleic acid (mRNA) to dictate the order of amino acids. Following transcription (the conversion of DNA into mRNA) an mRNA strand leaves the nucleus and enters the cytoplasm via the nuclear pore.
Explanation:
Your welcome!
Translation is the conversion of genetic information from the language of nucleic acid to protein, hence option 6 is correct.
Ribosomes, which are huge complexes of proteins and RNA, catalyze the translation process. Ribosomes read the RNA transcript and translate it one amino acid at a time into a protein.
Peptide bonds are used to connect the amino acids to produce a polypeptide chain. Following that, the polypeptide chain folds into its ultimate shape, which determines its function.
Translation is the process through which an RNA transcript is converted into a protein. This procedure takes place in the cell's cytoplasm.
Thus, the option 6 is correct.

4 t-shirts and a hat costs £31. 00 2 t-shirts and a hat costs £17. 0. How much does a t-shirt cost? how much does a hat cost?.
Answer:
T-Shirt Cost = £7
Hat Cost = £3
Explanation:
Important Information:
4 t-shirts and a hat costs £31.00
2 t-shirts and a hat costs £17.00.
Here we assume t-shirt be x and hat be y.
Explanation/Solution:
Based on the above information, the calculation is as follows:
4x + y = 31
2x + y = 17
Now subtract equation 2 from 1
2x = 14
x = 7
So y is
4(7) + y = 31
28 + y = 31
y = 3
Therefore we can conclude that The t-shirt cost £7 and Hat cost £3.
A cube with volume 8 $\text{cm}^3$ is cut in half by a plane which contains two edges of the cube. What is the area of the rectangle formed by the intersection of the plane and cube? express your answer in simplest radical form.
The area of the rectangle formed by the intersection of the plane and cube is [tex]4\sqrt{2}cm^2[/tex]
The diagram of the cube and the cutting plane is shown in the figure.
Since the cube has a volume of [tex]8cm^3[/tex], the sides are [tex]2cm[/tex] each.
From the diagram, the red rectangle is the rectangle formed from the intersection of the plane and the cube. It has an area given by
