28. Expand as much as possible using the properties of logarithms: log ((R/4)^3) Reading this, it was my understanding I needed to use rules two and three http://www.purplemath.com/modules/logrules.htm I should be using rule 2) logb(m/n) = logb(m) – logb(n), and 3) logb(m^n) = n · logb(m) My answer ...
As the title suggests, I've have some trouble studying for my algebra exam upcoming in regards to solving for X. If my writing is unclear, you can view the problem in pdf format here: http://www.csus.edu/math/courses/IADPracticeExamFormC.pdf The first problem (20) I believed I was doing right, but I...
Well, I'm in college and having taken algebra2 both in hs and college, I cannot recall ever using SIN,COS, Tangent ever. So I'm assuming it's geometry related Anyways, to view the problem you will need to go here: http://www.csus.edu/math/courses/IADPracticeExamFormC.pdf and view problem #16. The pr...
Thanks, yes I did check my question and this was throwing me off...I was wondering why my X never worked out in the equations. Edit: After reading the 1st solution manual, could I have simply marked no solution as soon as I saw the negative exponent? All of this information is very important as my t...
Sorry , I meant the link. And I now realized thanks to you, that since roots have to be positive I could of just plugged 0 or 1 in for x and finished in 2 minutes
If the line passing through the points (a, 1) and (6, 5) is parallel to the line passing through the points (9, 6) and (a + 7, 1), what is the value of a? I know that they need to have either the same slope, but I have no idea how to do this problem My work 5-1/6-a = 4/6-a 1-6/a+7-9 = -5/a-2 After t...
