Answer:
constant term
Step-by-step explanation:
I guess ... the factors of constant term.
Answer:
4.5
Step-by-step explanation:
To find the instantaneous rate of chance, take the derivative:
![f(x) = {x}^{2} - \frac{2}{x} - 1 \\ \frac{d}{dx} f(x) = 2x + \frac{2}{ {x}^{2} }](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%20%7Bx%7D%5E%7B2%7D%20%20-%20%20%5Cfrac%7B2%7D%7Bx%7D%20%20-%201%20%5C%5C%20%20%5Cfrac%7Bd%7D%7Bdx%7D%20f%28x%29%20%3D%202x%20%2B%20%20%5Cfrac%7B2%7D%7B%20%7Bx%7D%5E%7B2%7D%20%7D%20)
Remember to use power rule:
![\frac{d}{dx} {x}^{a} = a {x}^{a - 1}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bd%7D%7Bdx%7D%20%20%7Bx%7D%5E%7Ba%7D%20%20%3D%20a%20%7Bx%7D%5E%7Ba%20-%201%7D%20)
To differentiate -2/x, think of it as:
![- 2 {x}^{ - 1}](https://tex.z-dn.net/?f=%20-%202%20%7Bx%7D%5E%7B%20-%201%7D%20)
Then, substitute 2 for x:
![2(2) + \frac{2}{ {2}^{2} } \\ 4 + \frac{2}{4} = 4.5](https://tex.z-dn.net/?f=2%282%29%20%2B%20%20%5Cfrac%7B2%7D%7B%20%7B2%7D%5E%7B2%7D%20%7D%20%20%5C%5C%204%20%2B%20%20%5Cfrac%7B2%7D%7B4%7D%20%20%3D%204.5)
Yes. Easiest way too find it is plug them into your calculator, both solutions are .55555556. But if you don't have a calculator you can try to make the bottom numbers the same by seeing what they have in common...9. So 45/5=9 and 27/3=9. Then do the same to the top 25/5=5 and 15/3=5. Now we have 5/9 and 5/9 which are the same so they have the same proportions
5 is b because 3/6 is equivalent to 1/2
6 is a because 1/6 is less than half
It is called being proportional,
Ex. so every three grapes you eat, i eat four
every 6 you eat, I eat 8, etc. etc.
