1. ### Gravitational field strength (ratios)

ah that make sense, thanks for everything!
2. ### Gravitational field strength (ratios)

Homework Statement A 6.2*10^2-kg satellite above Earth's surface experiences a gravitational field strength of magnitude 4.5-N/kg. Knowing the gravitational field strength at Earth's surface and Earth's radius, how far above Earth's surface is the satellite? (Use ratio and proportion.)...
3. ### The Product Rule

Homework Statement If f(2) = 3, f'(2) = 5, g(2) = -1, g'(2) = -4, find (fg)'(2). Homework Equations if F(x) = f(x)g(x) F'(x) = f'(x)g(x) + g'(x)f(x) The Attempt at a Solution I have no idea how to attempt his question :(
4. ### Logarithm: Compound interest problem

ohhhh okay thanks alot!
5. ### Logarithm: Compound interest problem

Homework Statement How long does it take for a sum of money to double if it is invested at 8% compounded semi-annually? Homework Equations A = P(1+i)n A: Compounded amount P: Initial amount i: Interest rate n: Period The Attempt at a Solution A = P(1+i)n (2x) = (x)[1+(0.08)]2n (2n because...
6. ### ADVICE: Physics or Engineering?

Good luck to you too! And thanks for the advice and time! i really appreciate it!!!
7. ### ADVICE: Physics or Engineering?

Anywhere that would accept me! haha U of T, Wloo, Queens, McMaster, Ryerson, Ottawa, and Western are the schools i'm going to apply to Haha trying not to but it's kind of hard when everyone around is stressing as much as you are! And the pressure is adding on! xP
8. ### ADVICE: Physics or Engineering?

I'm schooling in Canada as well! But what I mean by chem course i meant my grade 12 chem mark isn't quite up to par yet so, i'm not sure if i should use it to apply to uni! But also no doubt I'm not going to give up on it either! and again thanks for the advice and time!
9. ### ADVICE: Physics or Engineering?

THANKS FOR YOUR INPUT and sharing your experience! I really appreciate it! No one has answered me thus far for the entire night! But I did some research online and it says that to get into EE chemistry is required... And of course I'm going to continue studying chemistry, although if I could...
10. ### ADVICE: Physics or Engineering?

I am currently in my last year of highschool, and I'm kind of torn between going on to study physics or engineering (more specifically electrical engineering) in university. Also if I choose to study engineering in university I understand that it requires Grade 12 chemistry and as of now my...
11. ### Absolute within an absolute

Oh i meant to type 1, sorry for the typo :(
12. ### Absolute within an absolute

Solve: | |x+1| +2| - | x-2 | = 3 Relevant equations: if |x| = a, then x = a; x = -a My attempt: |x+1| +2 - (x-2) = 3 ; |x+1| + 2 - (x-2) = -3 (by theorem provided by teacher above) |x+1| = x- 1 ; |x+1| = x-7 if |x+1| < 0: -(x+1) = x -1 -x - 1 = x - 1 -2x = 0 x = 0...
13. ### Equations Involving Radicals Question

OHHHHH That make sense!! thanks!!
14. ### Equations Involving Radicals Question

the first one Sorry i don't really know how to use the square root sign, pretty new to this
15. ### Equations Involving Radicals Question

(√(x-7)) / (√(x) - 2) = √2 √(x-7) = √(2) (√(x) - 2) x-7 = (√2x - 2√2) ^2 <------- square both sides x-7 = (√2x)^2 - 2(√2x)(2√2) + (√8)^2 x-7 = 2x - 8√x + 8 0 = x - 8√x +15 0 = x^2 - 64x + 225 <----- squared both sides to get rid of radical and plug into quadratic eqn. :P
16. ### Equations Involving Radicals Question

Solve for: √(x-7) / √(x) -2 = √2 My attempt at a solution: I solved for x and it comes out to: 0 = x^2 - 64x +225 and then i plugged it into the quadratic formula: [-(-64)±√((64)^2-4(1)(225))]/2 and my answer comes out to be: 32±√799 although the answer on the back of...
17. ### Remainder/factor theorem question

:biggrin: Okay I get it now! Thanks everybody for all your help!!! :smile: :!!)
18. ### Remainder/factor theorem question

ouu okay I see! But is there a shorter method to this? Thanks in advance
19. ### Remainder/factor theorem question

The question is Find "a" and "b": f(x) is ax^3 - bx^2 + 2x - 12 Divisor is x^2 - 5x +6 Remainder is 2x - 3 So what I tried to do was divide f(x) with the divisor and take the the remainder that I got and let it = 2x - 3 but I always get stuck in the end. My teacher suggested using the...
