Assume x and y are functions of t. Evaluate StartFraction dy Over dt EndFraction dy dt for 22xyminus−22xplus+33ycubed3equals=n egative 105−105, with the conditions StartFraction dx Over dt EndFraction dx dtequals=minus−99, xequals=33, yequals=minus−33.

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years

step-by-step explanation:

lol.

it's ok we all do this sometimes.

-aparri

substitute,

circle 1 = 5

circle 2 = 20

circle 3 = 44

in this case no matter how you add, you will always get a perfect square..

hence proved

happy to

pls mark as brainliest
