If sin theta = 4/5 and theta is in quadrant 2, the value of cot theta is . If necessary, use the slash mark ( / ) for a fraction bar.

The value √10 and √15 are plotted on the number line

Given the two similar triangles, how do i find the missing length? if a=4, b=5, and b'=7.5 find a'

Me! i really need to get this right before 9. prove the divisibility of 7^6+7^5-7^4 by 11. use factoring so you get a number times 11. just tell me the number. i need this done asap
