School and Work

The concept of it interests me, infrastructure and the like has always interested me. However the part that worries me is the math. I'm not terrible at math, never made less than a B but I am not great at it either where it all comes natural. With math, it usually takes me a bit of extra time to understand it and then I understand it. Algebra 1 and 2 i made about high B's. Adv. functions and modeling which had trig/algebra I made about a 98. When I have a calculator I usually do great.

So overall, I am worried about calculus and all of the other tough maths and I did not take pre-cal. As mentioned, I like the concept of building and helping shape urban environments it is just math I worry about failing. What do you think?

The problem is to subtract and simplify. . .

3 / (x^2+4x-5) - x / (x^2-1)

In the end I got . . .

(-x^2-2x+3) / (x+5)(x-1)(x+1)

If I'm wrong, can you show me how to do it please?
Thanks alot ! : )

Home >All Categories > Science & Mathematics >Physics >Open Question Britney Member since:February 23, 2011Total points:92 (Level 1)What are the conditions of a body which is acted upon by parallel co-planar forces?Answer Question

by dev Member since:December 25, 2010Total points:336 (Level 2)There are two conditions
(1) The vector sum of all the forces acting on the object must be zero.
Mathematically,?F vector=0. This condition ensures that the object remains at a
particular location and does not moving linearly (unless it is already in motion
with a constant uniform velocity).
(2) The algebraic sum of the torques about any axis of the object must be zero.
Mathematically ? torque vector=0, . This condition requires that the sum of the
counterclockwise torques must be equal to the sum of the clockwise torques
about the axis of rotation. Therefore when the net torque is zero, the object
remains in rotational equilibrium. This implies that either the object does not
rotate (rotational static equilibrium) or that it rotates with a constant angular
velocity (dynamic equilibrium)

Electric current is a flow of electric charge through a medium. This charge is typically carried by moving electrons in a conductor such as wire. (It can also be carried by ions in an electrolyte).

The SI unit for measuring the rate of flow of electric charge is the ampere, which is charge flowing through some surface at the rate of one coulomb per second. Electric current is measured using an ammeter
Mathematically it can be written as
Q = i * t ; where Q = charge in Coulomb, i = current in amp., and t = time in sec
so in your question Q = 10, 800 C, t = 1 hour = 60x60 = 3,600 sec
so 10,800 = i * 3,600 ; or
i = 10,800 / 3,600 = 3 amp. ---------- Answer

Hope this helped.

I had trouble swallowing pills for the longest time. First of all, see if you can get that ibuprofen in gel capsule form. Those don't taste as bitter and are much easier to swallow. Toss the pill into the back of your mouth, then take a gulp of water and swallow. If the pill doesn't go down right away, don't panic...take another gulp of water. You'll get it eventually.

Once you've gotten pretty good at swallowing gel capsules, it'll be easier to swallow actual pills. You can't keep those in your mouth for very long, though, because once they start dissolving they taste terrible.

My best advice is to stop psyching yourself up and DO IT! I hope that helps. Good luck!

let g = golf balls:

$12g + $42,000 = $15g
subtract $12g from both sides;

$42,000 = $3g

Divide both sides by $3

14,000 = g

Despite what the other posters are telling you, there actually is an answer. During the past somewhere, a university somewhere did some research into this and finally solved the problem. As it turns out, the chicken came first. The eggs from chickens are built from a chemical that is released from the inside of the chicken. Without that chemical release from the chicken, the egg would not be able to structually exist.

point-slope form:

y-7 = 9(x-9)
y - 7 = 9x - 81
y = 9x - 74

y = 9x - 74 is your answer
