Y'(x) = - (x^(-6/5))/5 + (x^(-4/5)) / 5 + 1
y'(32) = - (32^(-6/5))/5 + (32^(-4/5)) / 5 + 1 = -1/(64*5) + 1/(16*5) + 1 = (-1+4+320)/320 = 323/320
А) 1.2*100=120-7=113 +)
B) 1.2*(-15)=-18-7=-25 +)
C) 1.2*(-10)=-12-7=-19 -)
D) 1.2*300=3600-7=353 +)
(x-5)^2+(y-3)^2=R^2
(1-5)^2+(0-3)^2=R^2
R^2=25
R=5
ответ (x-5)^2+(y-3)^2=25
