if f(x)=kx, f'(x)=ln(k)*kx. Therefore, the derivative of 2x is ln(2)*2x.
k + 5k = 6k 2 x 3 x k
4x-9=k 4x=k+9 Divide by 4 to isolate the x x=(1/4)k+(9/4) x=1/4 k+ 9/4
x = ¼x^4 + 4x + k where k can be any number
x to the ninth power OR x to the 9th power OR x^9

Let X have a Poisson distribution.Therefore Pr(X=x) = e^(-k) * k^x/x! where x = 0, 1, 2, ...Normally the parameter is the Greek letter, lambda, but this site does not allow any such symbols!Then the moment generating function of the Poisson distribution isE[exp(tx)] = Sum[e^(tx)*Pr(X=x)] where the sum is over all non-negative integers, x.= Sum[e^tx * e^(-k) * k^x/x!]= Sum[(e^t)^x * e^(-k) * k^x/x!]= e^(-k) * Sum[(e^t)^x * k^x/x!]= e^(-k) * Sum[(k*e^t)^x /x!]= e^(-k) * e^(k*e^t)= e^[k*(e^t - 1)]
Factor them. k2 = k x k k2 - 1 = (k - 1)(k + 1) k2 - 2k + 1 = (k - 1)(k - 1) Combine the factors, eliminating duplicates. k2(k + 1)(k - 1)(k - 1) = k5 - k4 - k3 + k2, the LCM
k = x y x = k/y
if f(x)=kx, f'(x)=ln(k)*kx. Therefore, the derivative of 2x is ln(2)*2x.
k and -k right? -k x -1 =k k+k= 2 k= 1 unless you mean multiply then that would be -k x-1 =k k x k= 2 1.4142 rounded to the nearest ten thousandth
Use the formula: power = voltage x current x power factor If you don't know the power factor, assume it is 1 - this is close enough for many devices. In units: power (in watts) = voltage (in volts) x current (in amperes)
The area under a curve (ie between the curve and the x-axis) is found by integrating the curve with respect to x: A = ∫ y dx When limits to the integration are given, then the value of the area is the difference between the value of the integral at the limits. The lower limit is where the curve y = √x meets the x-axis, ie at y = 0 → √x = 0 → x = 0 The upper limit is the line x = k → the area is given by ∫ √x dx between 0 and k To integrate √x write it in power format: √x = x^½, giving: ∫ √x dx = ∫ x^½ dx = ⅔x^(3/2) + c The difference between the limits is the area: (⅔k^(3/2) + c) - (⅔0^(3/2) + c) = 18 → ⅔k^(3/2) = 18 → k^(3/2) = 18 ÷ ⅔ = 27 → k = 27^(2/3) = (27^⅓)² = 9 Thus k = 9.
∫ 10x dx Factor out the constant: 10 ∫ x dx Therefore, by the power rule, we obtain: 10x(1 + 1)/(1 + 1) + k = 10x²/2 + k = 5x² + k
I'm assuming that by ' IT ' you mean ' It ' for 'total current'.-- The effective resistance of 2k and 1k in parallel is 2/3 k ohms.-- The power dissipation is I2R = 0.003 x 2/3 k = 2 watts
K-x. In red!
k + 5k = 6k 2 x 3 x k
