Can someone help me with my Algebra 2 homework.?
Ok, my teacher explains things too fast. And I do not understand how to do this particular problen / step. Question: Write and equation in slope intercept form for the line that contains the given point and is perpendicular to the given line. problem : (3,-1), 12x + 4y = 8 If you guys can give a step by step instructions to how to do it I would gladly appreciate it :]
Can someone help me with my algebra 2 homework ?
Before I start, the angle variable "feta" is really spelled "theta." To calculate the amplitude of a sinusoidal function, look at the coefficient (the multiplier) outside of the function, if the function is sine or cosine. For example, the amplitude of y = 3 sin (theta) is 3. This is not the case with tangent, since it has a vertical asymptote at x = pi/2. So tangent has infinite amplitude. To find the period, look at what is inside the trigonometric function (inside the parenthesis). Divide 2*pi by the coefficient inside the parenthesis, and you will get the period. Remember, if there is no number inside the parenthesis, then the coefficient is one. Thus, the period for y = 3 sin (theta) is 2 pi (coefficient is 1). Also, the period for y = 6 sin (4*theta) is 0.5 pi (2 pi / 4). To find the phase shift, you have to look inside the parenthesis again. If you are adding to the angle, you will shift to the left. If you are subtracting from the angle, you will shift the function right. So for y = sin(theta + 90 degrees) + 2, the sine function will be shifted to the left 90 degrees. The vertical shift is found outside the trigonometric function. If you are adding to the function, you will move it up. If you are subtracting, you will move it down. This makes sense since you are adding or subtracting directly to the y value. For your example y = sin(theta + 90 degrees) + 2, you will move the sine function up 2 units. When you describe a transformation, you will need to apply all of the above characteristics: amplitude, period, phase shift, and vertical translation. Here's the first example y = 3 sin (3*theta) - 1 Amplitude: Increases by factor of 3 Period: Shrinks by a factor of 3 Phase Shift: None Vertical Translation: Down 1 unit Things get really tricky when you have an equation like this: y = 3 * (sin (3*(theta-180)) + 2) Is the vertical translation up 2 units? Not so fast. Multiply out the 3 so the equation looks like this: y = 3 * sin (3*(theta-180)) + 6 Now you can see the vertical displacement is really 6. You should do the same with the stuff inside the trigonometric function.
Math homework help?!? ALGEBRA 2!?
[-4,0) Unless this is restricted to the set of integers, it will be very hard to write in roster notation. Roster notation (assuming you only want integers): {-4, -3, -2, -1} Set Builder notation (assuming that you just have real numbers): {x|x is greater than or equal to -4 and less than 0} (10,21) Once again, if there are no restrictions, then it is very difficult to write in roster notation. Roster (assuming you only want the integers): {11, 12, 13, 14, 15, 16, 17, 18, 19, 20} Set builder (no restrictions): {x|x is greater than 10 and less than 21}

How can I help my son with his algebra homework when I don't even understand it?
Hello,Algebra is an interesting topic for student and teacher both. It is a little complicated but a good mental exercise.If you don’t get an idea of how to help your child. I have a simple and effective solution for you. 15 ways to do Algebra homework efficiently.I will give some certain tips on how you can teach your child a very effective way.A formula is a key for Algebra and max math problem. That should be memorized by the student.Do homework in step by stepSilence is more importance for study. Always work on that your child should study in a silent environment.Doing homework with a friend is also a good Idea. They will discuss the question and answer when they got stuck.Visit some online website regarding mathematics problems. That will give a clear Idea.That all are regarding how to teach your child if you don’t understand Algebra or Math problems.Thanks for reading.
Can anybody help me on my algebra 2 homework?
1.Let the no.of boys in the family be x+1 Therefore,each boy has x brothers(excluding the boy himself) and x sisters So the number of girls in the family is x Therefore each girl has x-1 sisters(excluding herslef,of course) and as assumed x+1 brothers But by the problem, (x-1)=(x+1)/2 +.2x-2=x+1 2x-x=1+2 +.x=3 Therefore there are 3 sosters amd 4 boys in the family and the no. of children is 7. so A is correct 2>Let the no. of children who lost 1 teddybear each be x Therefore,the no of children who lost two teddy bears each is 32-x According to the problem x+2(32-x)56 =>x+64-2x=56 or x=8 Therefore,8 children lost one teddy bear each A is correct
Please help me with my Algebra 2 homework!!?
Okay I need to know how to find a fourth-degree polynomial equation with integer coefficients, the roots of polynomial equations, the rational root theorem and how to use it to find possible rational roots, and acutual roots, and I also need to know of to find a third-degree polynomial equation with rational coefficients. Please help!! I'm horrible at math!!

I am overwhelmed with my Algebra 2 homework?
read ahead and do more problems; thats your only solution i promise, you will overcome your problem if you continuously PRACTISE those math problems! all it takes is drilling. i know this is hard to do because nobody likes to do that. its boring, dull and you have to look at math problems for at least half an hour straight? but if you want to have confidence again, do those problems in the textbook! it takes determination and hard work. just don't give in, and you will be able to understand. ask the teacher too! if you dont udnerstand ASK ASK ASK. its not embarassing; i bet you half the class will thank you for asking their question for them.
