I am really not sure but i think the answer is 29 is there any choices?!?
I found that because i divided 130.50 by 4.5. =)
Hope that helped
Log(10-4x) = log(10-3x) this means that:
10-4x = 10-3x ===> after solving we find that 4x=3x , that means x = 0
ED and EG are proportional
16/44
EC (33) is the same proportion to Side EF
Therefore EF is 33• 16/44 = 12
F(x)=-9/x which is equal to:
f(x)=-9x^(-1) So the power rule for differentiation is used...
Power rule: f(x)=x^e, df/dx=ex^(e-1) so:
df/dx=-9(-1)x^(-1-1)
df/dx=9x^(-2) or if you prefer...
df/dx=9/x^2
df/dx(6)=9/36=1/4
