Find the magnitude of vector v that has an initial point of (1, 3) and a terminal point of (7, 1) v=2√10
v=2√14
v=4√2
v=4√5

It's totally correct with no doubt

been looking for the answer havent been able to find it   but good luck with it

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )
