Consider a non-right triangle. a=39 b=25 c = 24.(a,b,c are the sides) Find A,B,C. (these are the degrees of the triangle) I know theres an equation: b^2= a ^2 + c^2 - 2accos(B) and sinA/a = sinB/b = sinC/c but when i do the problem i get A= 74.55 B = 38.16 C = 36.68 but that ...

Use implicit differentiation to find the slope of the tangent line to the curve y/(x-2y) = y^3 +9 (1,10/21) ive done this problem around 10 times and i still cant get it.... when i did it the last time i got -9-y^3/ 3y^2 x - 8y^3 - 19 and the slope around 0.4754 but it is ...

Calc.
Let h(x)=16-4x-(x^3) Find g(96). My work: 96= 16-4x-(x^3) (-x^3)-4x-80=0 Using the rational roots theorm, I found that x=-4 so h(-4)=96, therefore g(96)=-4. Find g'(96). My work: g'(96)= 1/(dh/dx at x=-4) 1/((-3(-4)^2)-4)= -1/52 Does this look ok? Also, my math teacher wanted ...
