1x^2-15 final answer
A psychologist is a person who studies normal and abnormal mental states, by experimenting, observing, and recording how people relate to one another and their environments.
Answer: a = 4, b = - 0.25, c = 0.5
8 is the quotient of either a/c or c/a. Additionally, ac = 2. Therefore either a or c must be 0.5, while the other is 4. This is because 4/0.5 = 8; 4 x 0.5 = 2.
-16 is the quotient of either a/b or b/a. At the same time, ab = -1. Due to this a cannot be 0.5, which would make b -8. If b is -8, then -8 x 0.5 does not equal -1. a must be 4. If a is 4, then c is 0.5. Solve for b, and you will find it is -0.25 (4/-0.25) = -16.
As a final proof, do the final step. The quotient of b/c is -0.5. -0.25/0.5 is in fact -0.5.
Hey I'm a freshman in IB in celebration high school in central Florida. If you're considering the IB program it's probably because you're bright and school has always come easy to you. The hardest part of IB is for the smartest kids who have always had it easy (myself included), because now it's not so easy. It means studying (I had never studied before), it means not allowing yourself to get distracted at all or you will work till 1-2 am daily. It also means less free time ( this was hardest on me). It is ready once you changed your mindset to "school first, play second" (something I've never had). But in the end you're so prepared to heavy workloads and for college. Colleges know this when they see an IB diploma so they like these kids a lot and accept them often (if you're grades are at the very minimum C or B average. (Ivy league won't accept less than A's across the board usually). In the end you likely get to a good college and do well in college that is the plus.
Both have a thin, brittle shell. The crust of the earth is broken into pieces, like the cracked shell of a hard boiled egg. The mantle of the earth is like the egg white, and the core of the earth lies in the center, like the egg yolk.
