Answer:
Step-by-step explanation:
Given the definite integral
, we to evaluate it. Using integration by substitution method.
Let u = 1-2x⁵ ...1
du/dx = -10x⁴
dx = du/-10x⁴.... 2
Substitute equation 1 and 2 into the integral function and evaluate the resulting integral as shown;

![= \dfrac{-1}{10} \int\limits {\dfrac{du}{u^5} } \\\\= \dfrac{-1}{10} \int\limits {{u^{-5}du } \\= \dfrac{-1}{10} [{\frac{u^{-5+1}}{-5+1}] \\\\= \dfrac{-1}{10} ({\frac{u^{-4}}{-4})\\\\](https://tex.z-dn.net/?f=%3D%20%5Cdfrac%7B-1%7D%7B10%7D%20%5Cint%5Climits%20%7B%5Cdfrac%7Bdu%7D%7Bu%5E5%7D%20%7D%20%20%5C%5C%5C%5C%3D%20%5Cdfrac%7B-1%7D%7B10%7D%20%5Cint%5Climits%20%7B%7Bu%5E%7B-5%7Ddu%20%7D%20%20%5C%5C%3D%20%5Cdfrac%7B-1%7D%7B10%7D%20%5B%7B%5Cfrac%7Bu%5E%7B-5%2B1%7D%7D%7B-5%2B1%7D%5D%20%20%5C%5C%5C%5C%3D%20%5Cdfrac%7B-1%7D%7B10%7D%20%28%7B%5Cfrac%7Bu%5E%7B-4%7D%7D%7B-4%7D%29%5C%5C%5C%5C)

substitute u = 1-2x⁵ into the result

Hence

Open or closed? because if it's closed then the the answer is D
Answer:
1,800
Step-by-step explanation:
1,819
----^
1 is less than five so you round down even if you round the 19 to 20 it would still be needed to round down because it is less than 50.
Hope this helps, have a good day! :)

Answer:
D. a−b=10 a=3b+4
Step-by-step explanation:
Difference between a and b means to subtract b from a
We have,
a-b=10
a is 4 more than 3 times b
4 more than means to add 4
3 times b means to multiply b by 3
Therefore, a=3 times b + 4
a=3b+4
a - b=10; a=3b+4
