So for this, we will be completing the square to solve for m. Firstly, subtract 8 on both sides:
![2m^2-16m=-8](https://tex.z-dn.net/?f=2m%5E2-16m%3D-8)
Next, divide both sides by 2:
![m^2-8m=-4](https://tex.z-dn.net/?f=m%5E2-8m%3D-4)
Next, we want to make the left side of the equation a perfect square. To find the constant of this perfect square, divide the m coefficient by 2, then square the quotient. In this case:
-8 ÷ 2 = -4, (-4)² = 16
Add 16 to both sides of the equation:
![m^2-8m+16=12](https://tex.z-dn.net/?f=m%5E2-8m%2B16%3D12)
Next, factor the left side:
![(m-4)^2=12](https://tex.z-dn.net/?f=%28m-4%29%5E2%3D12)
Next, square root both sides of the equation:
![m-4=\pm \sqrt{12}](https://tex.z-dn.net/?f=m-4%3D%5Cpm%20%5Csqrt%7B12%7D)
Next, add 4 to both sides of the equation:
![m=4\pm \sqrt{12}](https://tex.z-dn.net/?f=m%3D4%5Cpm%20%5Csqrt%7B12%7D)
Now, while this is your answer, you can further simplify the radical using the product rule of radicals:
- Product rule of radicals: √ab = √a × √b
√12 = √4 × √3 = 2√3.
![m=4\pm 2\sqrt{3}](https://tex.z-dn.net/?f=m%3D4%5Cpm%202%5Csqrt%7B3%7D)
<h2>Answer:</h2>
In exact form, your answer is ![m=4\pm \sqrt{12}\ \textsf{OR}\ m=4\pm 2\sqrt{3}](https://tex.z-dn.net/?f=m%3D4%5Cpm%20%5Csqrt%7B12%7D%5C%20%5Ctextsf%7BOR%7D%5C%20m%3D4%5Cpm%202%5Csqrt%7B3%7D)
In approximate form, your answers are (rounded to the hundreths) ![m=7.46, 0.54](https://tex.z-dn.net/?f=m%3D7.46%2C%200.54)
Answer:
The error interval for x is:
[3.65,3.74]
Step-by-step explanation:
The number after rounding off is obtained as:
3.7
We know that any of the number below on rounding off the number to the first decimal place will result in 3.7:
3.65 3.66 3.67 3.68 3.69 3.70 3.71 3.72 3.73 3.74
( Because if we have to round off a number present in decimals to n place then if there is a number greater than or equal to 5 at n+1 place then it will result to the one higher digit at nth place on rounding off and won't change the digit if it less than 5 )
Hence, the error interval is:
[3.65,3.74]
YESI had to reread it a couple of times.
N/d = 2/3 -------------------> 3n = 2d
(n + 2)/(d + 2) = 3/4 ------> 4n + 8 = 3d + 6
