This was one of my test questions today. Read it carefully.
A viewer knowledgeable in the science of fiction watching Star Wars can safely assume that:
A) The rebel heroes can see the light of an explosion in outer space.
B) The rebel heroes can hear the sound of an explosion outer...
Well here's a question.. how do you know which is the opposite and which is the adjacent? Let's say you are given a triangle with sides of 4, 5 and 6, and you are required to find the angles.. how do you know which method to use?
I have a test (today!) and I have no idea when my book will becoming so I really need to learn this. I thought about this problem more and here's what I've come up with:
so I draw a vector from origin (0,0) to (120, -60), an dfrom there I draw a line down to complete the right triangle. So...
I did.. thing is I don't know the formulas, or the method to solve it. I'm not looking for the answer, but rather for someone to explain how to tackle these problems. Thanks.
I haven't had precalc 2 yet, so I'm not too familiar with sin, cos, tan, but I need this for my physics class.
So if you guys don't mind giving me the formulas of sin, cos, and tan.. for example: Sin angle A = width/length etc. If I have a right triangle with a hypotonuse of 7, and an angle...
What is the formula? I have two problems:
1. What is the volume of a sphere with a radius of 5.0 m?
My initial guess was 5^3 = 125, but apparently the answer is 523.6.
2. The radius of the Earth is 6400 km. If the atmosphere is approximately 10 km high, then what is the volume of air...
Here's the problem.
Five children are pushing on a snowball, each pushing with a force of 10 N. Each is pushing at an angle of 45 relative to his neighbor. What is the net push on the ball?
Ok my prof went over this problem in class but moved through it so fast that I didn't understand...
It's true. First day of class he branded himself as a "learning assistor" and he wasn't kididng. He literally doesn't teach and requires us to read the book and learn it on our own. I have a test tomorrow, and I don't have a textbook (problems with ebay) but I do have review sheets so I have a...
Another concept my physics prof didn't teach the class. I would love to be able to attempt these problems but I have no idea what these concepts are or the formulas for them. I'm not looking for the answers to these problems here folks, but rather a method in which to solve them. Thanks!
1. A...
I've already started on the problem. As I'm new, I didn't know you had guidelines as to how to post questions for problems.
I already know let X be the number of oversized rackets, and let Y be the number of standard rackets.
The inequality part is what confuses me.
30 >= X >= 80 ...
This is really difficult, I have no idea how to go about this.
A manufacturer of tennis rackets makes a profit of $15 on each oversized racket and $8 on each standard racket. To meet dealer demand, daily production of standard rackets should be between 30 and 80 (inclusive), and prdouction of...
I can learn how to do the problems, but I never understand why I'm doing the problems. Exactly what am I proving or figuring out? I can do derivatives, but I really don't know what a derivative is, I just know how to solve a derivative problem. How do you figure the logic? I swear, Calculus was...
I am taking precalc now and yes I am very rusty on factoring, though FOIL is no problem for me. We made it past the chapter with all the factoring though, and now we are doing slops, intercepts, graphs, and synthetic division. Easy stuff.
What kind of math is in algebra based physics 1?
Precalc 2 is trigonometry with analytical geometry. Whatever that is... lol.
Biology 2 is just listed as General Biology 2. I don't know what it entails. My biology 1 class was horrid though... so many processes to memorize.. how cells split, both plant and animal, and we even had some organic...
