@Loser66 What is the length of the tangent to the circle (x+2)^2 + (y-3)^2 = 4 drawn from the point A(6,0) ?

OpenStudy (anonymous):

I will ask calculus as well

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

d= in root (x1-x2)^2 + (y1-y2)^2

OpenStudy (anonymous):

ohhhh ok then which will be

OpenStudy (anonymous):

root 73 but I dont have it at the answers

OpenStudy (anonymous):

ohhhh sorry its 5

OpenStudy (anonymous):

thank you man

OpenStudy (anonymous):

I owe you

OpenStudy (anonymous):

can you help me more please :D

OpenStudy (anonymous):

I just dont know how to draw or make a snapchat for the questions

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

yeah but it is not root 73

OpenStudy (anonymous):

its 5 I think

OpenStudy (anonymous):

oopppssss my bad its root 73

OpenStudy (anonymous):

there has been a mistake mate . it was A(-6,0) sorry for that

OpenStudy (anonymous):

yeah but I didnt understand that part how you found the radius

OpenStudy (anonymous):

ohhh ok you mean its from the centre

OpenStudy (anonymous):

right ?

OpenStudy (anonymous):

ok so OB is 2 with pythagoras it will be

OpenStudy (anonymous):

just one more question

OpenStudy (anonymous):

the answer will be root 21

OpenStudy (anonymous):

but why the 90 degree became what you called as B ?

OpenStudy (anonymous):

Yoou mean because of the tangent

OpenStudy (anonymous):

which passes through the circle always make it 90 degrees .

OpenStudy (anonymous):

Thanks a lot men . Do you mind If I will ask you more questions . Because I really do need your help for my exam

OpenStudy (anonymous):

thanks mate

OpenStudy (anonymous):

to here

OpenStudy (anonymous):

or?

OpenStudy (loser66):

here

OpenStudy (loser66):

I will delete the previous problem to save the time to scroll down, ok?

OpenStudy (anonymous):

ok The remainders when a polynomial P(x) is divided by x-2 and x+1 are respectively 3 and -2. The remainder when P(x) is divided by (x^2-x-2)is K(x). What is the value of K(-4) ?

OpenStudy (anonymous):

Did you get the question ?

OpenStudy (loser66):

Yes, I am thinking.

OpenStudy (anonymous):

ok.

OpenStudy (anonymous):

anything :D

OpenStudy (loser66):
