Answer:
2.2
Step-by-step explanation:
41/9 is 2.15789473684
since you need it to the nearest tenth, just get rid of the other numbers past the five, you will then have 2.15
since you are looking for the nearest tenth, you need to look at the 2nd number after the decimal place to determine whether it rounds up or down. ( a helpful rule is 5 or above, give it a shove. 4 or below, leave it alone. because the 2nd digit is 5 you need to give the 1 a shove and turn it into a 2. Since you gave the 5 a shove, you need to get rid of that 2nd digit in your answer.
FINAL ANSWER: 2.2
Solution
Given the quadratic equation
we need to find the zeros of the equation
To do that, we use the completing the square method
Step 1. Add 38 to both sides
Step 2: add the square of half of the coefficient of x to both sides
That is;
Step 3: Simplify the above expression;
![\begin{gathered} \Rightarrow x-1=\pm\sqrt[]{39} \\ \\ \Rightarrow x=1\pm\sqrt[]{39} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5CRightarrow%20x-1%3D%5Cpm%5Csqrt%5B%5D%7B39%7D%20%5C%5C%20%20%5C%5C%20%5CRightarrow%20x%3D1%5Cpm%5Csqrt%5B%5D%7B39%7D%20%5Cend%7Bgathered%7D)
Answer:
3.64% (when rounded to the nearest hundredth)
Step-by-step explanation:
I'm assuming by 5700 you actually mean 57,000.
Calculate the percent change:
(57,000-55,000)/55,000 *100
(2000/55000)x100
0.036363x100
3.6363 rounded to the nearest hundredth is 3.64
