Find f'(a) f(t)=2t+1/t+3
GaryK [48]
I'm going to rewrite f(t) to make it a little easier to use the power rule:
f(t)=2t+t^{-1}+3

Now just take the derivative using the power rule:
f'(t)=2-t^{-2}

Since they ask for f'(a), we need to replace the t's with a's:
f'(a)=2-a^{-2}

PLEASE HELP ASAP!!! CORRECT ANSWERS ONLY PLEASE!!!
balu736 [363]

x equals 4 and y equals 5 . so the formula would be 5x+12y=80 and if we need 4 of the small boxes we sub x for 4 and we get 5(4) =20. Next, 80 minus 20 is 60, and the equation would now be 12y=60. we now divide both sides by 12 and we get left with y=5.  5x + 12y = 80  5(4) + 12(5)=80  20+60=80. That is all.  I hope that doesn't sound confusing

Beginning inventory10 units @ $10 per unit First purchase35 units @ $11 per unit First sale20 units Second purchase40 units @ $1
il63 [147K]

Answer:

option C

Step-by-step explanation:

given,

Beginning inventory             10 units @ $10 per unit

First purchase                        35 units @ $11 per unit

Second purchase                  40 units @ $12 per unit

Third purchase                       15 units @ $13 per unit

first sale = 20 units

second sale = 35 units

now,

unit left after first sale = 35 - 20 = 15 units @ $11 per unit

unit left after second sale = 40 - 35 = 5 @ $12 per unit

third purchase =  15 units @ $13 per unit

inventory  = 10 units @ $10 per unit + 15 units @ $11 per unit + 5 @ $12 per unit + 15 units @ $13 per unit

                = 100 + 165 + 60 + 195

                = $ 520

hence, the correct answer is option C
