Homework Help: 2nd Grade

Post a New Question | Current Questions

HELP !!! Algebra 2
Try substituting those values, and you will see they do not fit either equation. looking at the 2nd equation, y = x+2, so x+2 = x^2+5x-3 x^2 + 4x - 5 = 0 (x+5)(x-1) = 0 x = -5 or 1 so, y = -3 or 3 the solutions are thus (-5,-3)(1,3)

#12 just plug in the numbers x = (6±√(36+160))/8 = (6±14)/8 = 6/8 + 14/8 or 6/8 - 14/8 = 5/2 or -1 #13 √-16 = √(16 * -1) = √16√-1 = 4i #14 since i*i = -1, 1/i = -i (-5+i)/2i = -5/2i + i/2i = 5/2 i + 1/2 or, in standard form, 1/2 + 5/...

domain: {-1,2} range: {2,4,6} domain is the x-coordinate (1st value) range is the y-coordinate (2nd value) f(x) is certainly not x^2 + 2 (-1)^2 + 2 = 3, not 4 (2,6) fits, but (2,2) does not. In fact, since (2,2) and (2,6) contain the same x-value, but different y-values, these...

as many as 4. If one number has fewer digits than the other, it's smaller. The number with the smaller first digit is smaller. If the first digits are the same, go on (3987,3762) similarly for the 2nd, 3rd, 4th digits

Physics (2nd question)
Apparently you have already answered question 1. If not, see the "related Question" below. Question 2: If the ball starts at a height of Ho = 44 m, if loses the available kinetic energy until it reaches the maximum height Hmax g*Ho + Vo^2/2 = g*Hmax (Hmax-Ho)= Vo^2/(...

physics
aq = (V-Vo)/t = (-9.3-15.5) 0.015=-1660 m/s^2. NOTE: The final velocity is in the opposite direction. Therefore, it is NEGATIVE. A 2nd interpretation: While the ball is in contact with the wall, its' velocity is o. a = (0-15.5) / 0.015 = 1033.3 m/s^2.

How far have you gotten? Copying and pasting the equations to solve? That's not too far. to solve polynomials, set everything on one side equal to zero: x^2 + 6x + 1 = 0 try using the quadratic formula for this one. For the 2nd one, since you have basically, a^2 = b^2, ...

You're in 8th grade. You can certainly at least try to answer those questions. Is 8th grade going to be too hard for you? Maybe you should rethink your dreams of going to college for 8 years or so.

Phys
no. once two opposite and equal forces are acting on the body, its net acceleration is zero. So, whatever velocity it had when the 2nd force started, it will keep that velocity.

7x^2 + 4x - 13 = 8 multiply by 7 to get a perfect square on the 2nd-degree term: 49x^2 + 28x = 147 49x^2 + 28x + 4 = 147 + 4 (7x+2)^2 = 151 7x = -2 ± √151 x = (-2 ± √151)/7
