an equation of the line tangent to the graph of f(x)=x(1-2x)^3 at the point (1,-1) is? 先翻译成中文:求函数f(x)=x(1-2x)^3在点(1,-1)处的切线方程.f'(x)=(1-2x)^3+3x(1-2x)^2*(-2)=(1-2x)^2*[(1-8x)]当x=1,f'(x)=-7所以切线方程为y+1=f'(x)(x-1)=-...

The value of tanθ of the line is the slope of the tangent and in the expression above, the right-hand side is the derivative of the function at that point.Answer and Explanation: We need to find the equation of the line tangent to the curve x2+y2=1...
The axis of symmetry always passes through the vertex and focus of the parabolic curve. So the x-coordinate of the vertex is the equation of the axis of symmetry. The standard quadratic function can be represented as: f(x)=ax2+bx+c,a≠0 ...
To find the inverse of a function we swap the x and y variables in {eq}y = f(x) {/eq} to obtain the equation {eq}x = f(y) {/eq}, solving the equation for x. If this can be done in a unique way, then the function is invertible and the solution found will give the ...
This is the equation for a simple linear regression. here, y = Dependent variable. β 0 = the intercept, it is constant. β 1 = Coefficient of independent variable. x = Indepentent variable. $ \epsilon$ = error or residual. We use this function to predict the value of a dependent var...
As a result, IV estimates of LATE for ACE/ARB use on 1-year survival for post-AMI patients should fall between the RCT estimates described previously. In addition, all else equal, if essential heterogeneity is occurring we expect that LATE estimates will be biased high and that the bias ...
And from that equation, I can see: y(t)=202−x2(t)−−−−−−−−−√y(t)=202−x2(t) However, in order to use the information appearing in the problem, replacingx(t)x(t)by 12 seems to make sense:
What is the pressure exerted on the surface? Write the formula. The time period of an object depends upon density, radius, and surface tension. Derive an equation for it. The surface tension Y , of a liquid, depends on the density, P , acceleration of gravity, g , and the height, h...
