integration

Help on this question please?

part ai you just multiplied the integral by root 8 so it would just be 10root8

part aii you just do the integral from 0 to 1 of root x

and then add 10 to that

part b you do the integral from 1 to a of root x

Then make it equal to 10 and solve for a

What about the a

Ooh nvm u just have to integrate it part b is where u need to find a

Isn't is just that part ai = 10

So then using that u can find a right ?

[lapis urchin]

in the question it gave u that the integral from 1 to a of sqrt x is 10

and it part ai its the same integral just multiplied by sqrt 8

so you just multiply the area given which is 10 by sqrt 8
