I have the first part of the question (0.061). I need the second part.

I believe it would be 42 I got that by multiplying her current height by the percentage that she grew. (36 in)(1.17%) The 1 being her current height and the .17 being what she grew = 1.17

108/87 = 1.2414 = 124.14% Then you subtract 100% of what you got because that was your original number 124.14% - 100% = 24.14% Its 24.14% increase

Another way you could do it is do 95/80 = 1.1875 x 100 = 118.75 Then subtract 100% from that 118.75% - 100% = 18.75% whoch rounds up to 18.8%

ok what is rho? I know the answer to this problem is 9.96 m because our teacher gave us the answer

f(x)= 12x ________ sinx+cosx thats how the problem is and i need to find f'(-pie)

ok how about this one: f(x)=12x/sinx+cosx find f'(-pie) this is what i did: 12(-pi)/(0+(-1)) = 12pi is that right what am i doing wrong and what would be the answer

thats not the answer

yeah its 12x/(sinx+cosx) but in my problem there is no ( ) but yeah its the same thing but what would the equation be to plug in (-pie)

im not saying it like that and i did the work but its not right answer the computer says when i put the answer in it says incorrect. this is what i did: 12(-pi)/(0+(-1)) = 12pi but its not right i don't know why?

f'(-pie) that's what i need to find

sorry about that and i said yes that was the way but in the computer it doesnt have the parenthesis but yeah its the same way that the problem im trying to solve

im confused on this problem and i really need some help if you can help me and yes that is the problem i am trying to solve i would appreciate it

yes i need to find the derivative of f'(-pie)

this is the equation: f(x)=12x/(sinx+cosx) and i need to find: f'(-pie)
