I have a math test tomorrow, and I need some help?
Hi Sharon ! I wish you had given a sketch for the problem, as otherwise there could be some misunderstanding as to what exactly is meant I take it that the center of the arch at the LOWER END is 3m from the water while the top of the bridge is 4m from the surface of the water We can always choose the axes to suit our convenience, so let us choose the centre of the arch at the lower end as (0,0) with the positive direction of the x-axis going downwards towards the water (a) The equation of the parabola will then be y^2 = ax Plugging in the values, we get 25 = 3a, so a = 25/3 and the desired equation is y^2 = (25/3)x b) 2 metres from the centre of the bridge, 4 = (25/3)x or x = 12/25 = 0.48m To this we have to add 1m as the top of the bridge is 4m from the surface of the water while the arch is only 3m high Thus thickness of concrete 2m from the center of the bridge = 1.48m Hope this helps !

I have a math test tomorrow and don't understand any of the concepts.?
Well the answer is really dependent on a lot of things. For example: How much material will the exam cover? What was the last thing that you did understand? It may be the case that it is too late to help yourself, but there are a few strategies that may help. I would start by making note cards for all of the definitions listed in the material on the exam. Without understanding the definitions, you cannot understand any deeper concepts built on those. Quiz yourself on the definitions, and remember that in mathematics, each word in a definition has a purpose and the order of the words usually matters. Once you have definitions down, on one sheet of paper, make a list of all of the key concepts in the chapters (i.e. the subsections x.1, x.2, x.3, etc.). Then start working on each one, one at a time, crossing them off as you finish. Most books include a review section at the end of the chapter with exam level questions for practice. Focus on those instead of the problems after each section. This isn't ideal, but in one night, it's all you can do. Be prepared for very little sleep. The lack of sleep won't really hit you until later in the day, especially if you eat a full breakfast with a good amount of calories and protein. If your test is in the morning, it wouldn't hurt to drink a couple cups of coffee. If it is in the afternoon, stay away. You will have crashed by the time it rolls around. Also, make sure your lunch has adequate nutrients as well. Good luck. I hope I helped.
I have a maths test tomorrow and I forgot my books. What should I do?
If you can remember the topics covered by the exam, you can search the math lessons online and then try to learn from it. You can also search the topics on YouTube and find lesson videos.If you want to practice your Math skills, you can also search Math exercises online and try to answer it. It would be better if the exercise has an answer key so you will know what are the correct answers instantly.*Based on personal experience. When I was taking Math and Chemistry subjects in my 1st and 2nd year of college.
I'm nervous about a math test tomorrow?
Hey there! I get all worked up about tests and things too - I am a big stresser! I would look over all your notes that you have for this unit, you can also go on https://homeworkhelp.ilc.org/secure/login.php and view lessons on your topic.. this may help you! For the stressing part, just take deep breathes, get a good night sleep, and think positive.. I would also have a good breakfast tomorrow, as you will need your strength. Also, I know my teacher gives part marks if you explain your answers.. try to show all of your work, and put your answers in steps to make it look like you know what you are doing. Good luck!
I have a math test tomorrow but I don't know anything about it!!?
What grade are you in and what kind of expressions are you talking about? If you mean solving Algebraic expressions then that's quite easy. Example: y = (1 + 4x) / (7 - 9x) Multiply both sides by (7 - 9x) y(7 - 9x) = 1 + 4x Distribute 7y - 9xy = 1 + 4x Add 9xy to both sides to get the 2 terms with x on the right 7y = 1 + 9xy + 4x Subtract 1 from both sides 7y - 1 = 9xy + 4x Factor out an x on the right side 7y - 1 = x(9y + 4) Divide both sides by 9y + 4 x = (7y - 1) / (9y + 4) I suggest asking your parents or calling up a friend .
What can i do for my math test tomorrow that i haven't studied for.I am doomed,I AM GOING TO FAIL.?
