Turn in #8 is due Thursday, Dec. 22, 2016!

On the Partial Fractions HW worksheet, #8 on the answer sheet has the -1 over the (x+4) and the 1 with the (x-1) but I don't understand why these are flipped because when you cover the (x+4) and put -4 into the other part of the expression, you get -1 and shouldn't that go over the (x+4) then because that's the part that was covered?
ReplyDeleteOops the answer sheet has 1 over the (x+4) and -1 over the (x-1), but I'm getting that the -1 should go over the (x+4) and the 1 over (x-1)
DeleteOn pg.312 #57c I keep getting k=48 when it's supposed to be 16, what equation do I use to solve for K?
ReplyDeletePlug in the initial condition immediately after taking the integral.
DeleteHow can I figure out where the graph is both decreasing and concave up? (1b)
ReplyDeleteFind where the first derivative is negative AND where the second dervative is positive. Pay close attention to the wording of the question.

I'm confused of how to draw the solution curve of slope fields...I can't tell the pattern of the field based on my sketches. Any tips? Question 4a
ReplyDeleteStart at the initial point and draw a short segment parallel to the slope at that point. Once you arrive at the next "tick" adjust your slope accordingly.
DeleteIf you do part b of that problem and solve for the equation it ends up giving you an equation that can be used for part a.

for 2c do we need to solve for c?
ReplyDelete- Andrew Saad
I think so because it tells you to use the given initial value and you wouldn't need that for 2c unless solving for c for h(x)
DeleteDoes 3b need an actual explanation to go with the question?
ReplyDeleteNot necessarily, you could provide an inequality that describes the region in the x-y plane.
DeleteHow do you know if the answer to 4c is positive or negative?
ReplyDeleteLook at the initial condition provided.
DeleteOn the turn in #1c is C a plynomial?
ReplyDeleteIt would be a polynomial if it contained multiple terms, sometimes raised to different powers, and is continuous always.

On the turn in p.312 #57, do you solve for h and then put h back into the original equation we were given?
ReplyDeleteon 312 #57, can we solve with related rates?
