Answer:
Required value is 
.
Step-by-step explanation:
We have to find the value of,
where, 
To convert it in polar form let 
and substitute in (1) we get,
Assuming,
then,
![du=-\sin\theta d\theta\implies-du=\sin\thetad\theta[tex]For [tex]\theta=0, u=1](https://tex.z-dn.net/?f=du%3D-%5Csin%5Ctheta%20d%5Ctheta%5Cimplies-du%3D%5Csin%5Cthetad%5Ctheta%5Btex%5D%3C%2Fp%3E%3Cp%3EFor%20%5Btex%5D%5Ctheta%3D0%2C%20u%3D1)
and 
gives u=-1. Hence,
![=\Big[\frac{u^3}{3}\Big]_{-1}^{1}\times\Big[\frac{r^5}{5}\Big]_{0}^{5}](https://tex.z-dn.net/?f=%3D%5CBig%5B%5Cfrac%7Bu%5E3%7D%7B3%7D%5CBig%5D_%7B-1%7D%5E%7B1%7D%5Ctimes%5CBig%5B%5Cfrac%7Br%5E5%7D%7B5%7D%5CBig%5D_%7B0%7D%5E%7B5%7D)
Slope is rise over run, or the change in y over the change in x. So, you go up vertically then directly horizontal and whatever the change is is the slope.
For example, the first one is -1/3. It's slope is going down to the right, so it's negative . It goes down 1 (y value) and over to the right 3 (x value). Since it goes down and to the right it is a slope of -1/3.
I used example numbers. If you need any clarification, let me know.
If she answered all then she would have gotten 179 wrong. If I understand 200 questions and 11% on the test then 179 wrong and 21 right. So if you are asking how many she did not answer I would assume the questions she got wrong were the questions she did not answer which would be 179.
Answer:
The order of operations says that operations must be done in the following order: parentheses, exponents, multiplication, division, addition, and subtraction. You can also create a little phrase to go along with this, like "Please Excuse My Dear Aunt Sally." Whatever you choose, make sure that you know all six steps of the order of operations very well. The order of operations tells us the order to solve steps in expressions with more than one operation. First, we solve any operations inside of parentheses or brackets. Second, we solve any exponents. Third, we solve all multiplication and division from left to right.
