URGENT (Pre-Cal) For f(x)=8x-7 and g(x)=x+7 / 8 find the following functions?
A. (f * g)(x)=
B. (g * f)(x)=
C. (f * g)(8)=
D. (g * f)(8)=
I am taking my final exam for pre-cal RIGHT NOW. My average is 71. I'm pretty sure I'm going to pass but I'd love it if someone would help me out by giving me the answer or telling me how to solve this. It's a comprehensive final and I simply do not remember how to solve this from 4 months ago.

1 AnswerMathematics7 years agoURGENT! (Pre-cal) 1/8[5log(x+9)-logx-log(x^2-16)]?
It says: Use properties of logarithms to condense the logarithmic expression. Write the expression as a single logarithm whose coefficient is 1. Where possible evaluate logarithmic expressions.
I'm taking my pre-cal final exam online RIGHT NOW. My current average is a 71, whether I graduate depends of this test. Yes I know it is cheating, just please help.
1 AnswerHomework Help7 years ago(Pre-Cal) How can I get the partial fraction decomposition of (10x^2 - 18x - 15) / ((x+8)(x+5)^2) with WolframAlpha.?
I will need to solve several problems similar to this for my homework, as well as for an upcoming test.
WolframAlpha gives me the partial fraction expansion, but NOT the decomposition, which is what I need.
If someone could tell me how I can get the P.F.D. using WolframAlpha, that would be perfecto.

1 AnswerMathematics7 years agoUse synthetic division and the remainder theorem to find the indicated function value.?
f(x)=6x^3 - 2x^2 - 3x + 4; f(-4)
Could someone please help me solve this? Does it mean I am simply supposed to replace f(x) with f(-4) and solve?
2 AnswersMathematics7 years agoHow do I solve this with Wolfram Alpha?
I'm not looking for the answer, but rather how I can get the answer with Wolfram Alpha...
The following function is given.
f(x)=x^3 - 5x^2 - 4x + 20
A. List all rational zeros that are possible according to the Rational Zero Theorem.
B. Use synthethic division to test several possible rational zeros in order to identify one actual zero.

Software8 years agoQuestion about becoming a conscientious objector?
I will have to register for the Selective Service soon. I don't want to register but I hear that I have too since I'm enrolled at a public college. Therefore I wish to register as a conscientious objector. I'm gravely sorrowful of American foreign policy, it's bad enough that my tax dollars have to kill people, I will not take part in the bloodshed any further. I realize the draft is not in effect but following what's going on, it's easy to see how things might get out of hand, like another Vietnam. I will not fight in a preemptive war of aggression. What kind of questions will they ask me? What is required of me to gain conscientious objector status?
3 AnswersMilitary9 years agoHow long does it take wine to ferment?
I took a 2 liter of Grape Juice and added a packet of Baker's yeast. It's been sitting for about 3-4 days. I've heard that the yeast will survive until ~15% alcohol content, which is about what I am trying to achieve. I'm not really concerned with taste or aging, just want some booze for when I'm bored. I had about 12 ounces last night and it felt like I drank maybe 1/2 bottle of beer so clearly the alcohol content is pretty low at this point, perhaps 5%. I added a cup of sugar to the mix in hopes of speeding up the process, if nothing else it will improve the taste at the end. How much longer will it take before the alcohol content is maxed. If it wasn't obvious why I'm going through all this trouble for what is almost surely going to be a shi*** tasting wine, it's because I'm not 21.

For the situation described, determine the amount of the loan's discount, the net amount of the money you receive, and the loan's actual interest rate, to the nearest tenth of a percent. Show work. This is a homework question, I can't find out how to work in my text book. Will choose best answer.
2 AnswersPersonal Finance9 years agoInformation about immigrating to Canada?
I'm an American citizen lived here my whole life and have become quite fed up with the state of affairs and ashamed of my country's aggression toward other nations. I plan on moving to Canada in the semi-near future, I was thinking either BC or Toronto. Currently I'm a student doing very well in junior college and planning to go to med school (possibly in Canada) after I finish my 2 year associate of science. Ultimately I'd like to become a citizen. I've read some on the government website but having a hard time wading through all the jargon. What would be the best way to work toward this goal?
