Question

Please help me with my calculus homework, really appreciate it.

Answer 1

For this case we have the following expression:

`\sum ^(10)_(i=1)2i^2+4i-5`

Then we can replace and we have:

`2\cdot(10(10+1)(2\cdot10+1))/(6)+4\cdot(10(10+1))/(2)-5\cdot10=2\cdot385+4\cdot55-50`

Solving we have:

770+ 220 -50= 940
