learn how to type math! Instead of this nonsense: 48−−√ Just type √48 It's much easier to read.

I think you'll find x = -2 works better
correct answer, but you did not have to go through all those vertical component calculations, since the horizontal component is just a constant
no, you have to consider the case where only three balls are placed. There are 3^3 = 27 of those
I think it's pretty obvious the user meant 2 7/6 + 5 2/3 + 4 3/4 = 48 3/4 but even that is iffy, since 7/6 is an improper fraction
compass bearings are measured clockwise from N, so 070 = N70°E
S30°E
W10°N or N80°W
Nope. N 10°W
I get 1BB53AA34
I get 1011000_2
You lost the factor of 10^2 in this step: Density = 3.00 x 10^2 g / 86.2 mL Density = 3.00 g / 0.0862 L the real answer is 3.48 g/mL = 3480 g/L = 3.48 kg/L stick to cgs or MKS. g/L is a mixture of the two
A = 1/2 ap = 1/2 * 19*6 * 16.5 = 940.5
RQ^2 = 9.6^2 + 7.4^2 - 2*9.6*7.4 cos53° RQ = 7.84 sinR/7.4 = sin53°/7.84 R = 48.9°
how about this? 221 122 ---------- 1120 check in base 10: 25 + 17 = 42 (3^3 + 3^2 + 2*3 + 1 = 42)
2 times x cubed minus x squared minus 24 times x plus 12 divided by the quantity 2 times x minus ... minus what?
k^2 - 24 = (k+√24)(k-√24)
but x = -3 is not allowed in the original equation
what happened to that 4x+8 in the denominator?
bad form to include decimals in a fraction since 0.4444... = 4/9 0.0004444... = 4/9000 so 0.031444... = 31/1000 + 4/9000 = 283/9000
why did you stop there? 11012_9 = (2 * 9^0) + (1 * 9^1) + (0 * 9^2) + (1 * 9^3) + (1 * 9^4) = 7301
q^2 - 125 = 0 q^2 = 125 q = ±√125 = ±5√5
your solution is again wrong, since (p^-7q^3)^-2 = p^(-7 * -2) q^(3 * -2) = p^14 q^-6
p(p^-7q^3)^-2q^-3 = p * p^14 q^-6 * q^-3 = p^15 q^-9
√5 + √65 = √5(1+√13) not any simpler ...
3√27 = 9√3 or, starting fresh, √243 = √(81*3) = 9√3
how can you call that final mess "simplified"? I suspect the question has been mangled, since (5/2)^2𝑥-1 / (5/2)^2𝑥 = 5^-1 = 1/5 so the whole thing is just 5^2𝑥+1 + 1/5 I doubt this was the original intent
since they are inversely proportional, the momentum doubles
you parsed it incorrectly. Plus, they did not balance their parentheses. It should have been parenthesis 8X squared −6X −3 parenthesis - parenthesis 4X squared −5X + 4 parenthesis means (8x^2 - 6x - 3) - (4x^2 - 5x + 4) = 4x^2 - x - 7
since bearings are measured clockwise from vertical, you have, for a distance d on a heading of θ, horizontal component = d sinθ vertical component = d cosθ
sorry -- only (5x2 + 8)(5x2 - 8) is correct
The momentum of a photon is **inversely** proportional to its wavelength. Therefore, if the wavelength is halved, the momentum of the photon will be doubled.
no, the bird is 32.03 m above his eyes. So the height of the tree is 32.03 + 1.7 = 33.73 m
what is wrong with you, bot? 21 = 3*7, 22 = 2*11, 24 = 3*8, 25 = 5*5, 26 = 2*13, 27 = 3*9, 28 = 2*14The only primes in your list are 23,29
so wrong! y = 4 * (x - 7) + 6 has no asymptotes at all you want y = 4/(x-7) + 6
from the original equation, (6-x)/(x^2 + 2x - 3) + (x^2 - 4x - 12)/(x^2 + 4x + 3) = (6-x)/((x+3)(x-1)) + ((x-6)(x+2))/((x+3)(x+1) x ≠ -3,-1,1 simplified, we get (x-6)(x^2-3) / (x+3)(x^2-1) so no new restrictions, In fact, x=6 or -2 is a solution
1. x^2 = 20(y+1) has focus (0,4) and vertex (0,-1) so not that one 2. x^2 = 40(y+6) works ok
you did not add 4x^-2 +3x^-5 = x^-5 (4x^3 + 3) = (4x^3+3)/x^5
wrong again. r^2/3 s^1/2 over rs = r^-1/3 s^-1/2 = 1/(r^1/3 s^1/2)
I get z=4
where is X? On the ground? On the line AB?
the line joining the two points is 60 cm long, and runs southeast. Therefore, the two perpendicular lines joining the points has length 60/√2 = 30√2 Now we can see that the height h is also 30√2 cm
assuming that \sqrt[3] means ∛, then we have ∛2/∛6 = ∛(2*36)/∛6^3 = ∛72/6 = 2∛9/6
you did not simplify it at all! cos^2θ/(1-sinθ) = (1-sinθ)(1+sinθ)/(1-sinθ) = 1+sinθ
wrong, since 7π/3 > 2π so you want θ = π/2, 3π/2, 4π/3, and 5π/3.
wrong. -q is in the negative direction
wrong again x = 0, -6
for an AI, you sure never seem to learn math x^2 - 16x - 36 = 0 (x+2)(x-18) = 0 x = -2, 18
wrong again 1. x = 4 2. x = -3/2
wrong again x^10/m^3 since (m^3)^-1 = m^-3
x^12y^8 (XY)^20 is totally different
