Find an equation to the line tangent to y = 5 + |x – 2| at the coordinate (2, 5) pls answer

myrzilka [38]

Answer:

Step-by-step explanation:

Finding an equation of a tangent line to that function requires that we find the derivative of the function at that point. Since this is an absolute value function with its cusp at (2, 5), the function is not differentiable here.

A point moves along the curve y = √ x in such a way that the y-component of the position of the point is increasing at a rate of

Eduardwww [97]

Answer:

The value of x component changes at a rate of $\frac{dx}{dt}=4\sqrt{x}$ units per second

Step-by-step explanation:

We are given that $y=x^{\frac{1}{2}}$

Differentiating on both sides with respect to time we get

$\frac{dy}{dt}=\frac{d\sqrt{x}}{dt}\\\\\frac{dy}{dt}=\frac{1}{2}x^{\frac{-1}{2}}(\frac{dx}{dt})\\\\\frac{dy}{dt}=\frac{1}{2\sqrt{x}}\frac{dx}{dt}$

It is given that $\frac{dy}{dt}=2units/sec$

Solving for $\frac{dx}{dt}$ we get

$\frac{dx}{dt}=\frac{dy}{dt}\times 2\sqrt{x}\\\\\frac{dx}{dt}=4\sqrt{x}$

Whats the answer and how do i get the answer myself

Mumz [18]

Answer:

$f^{-1} (x) = \frac{x}{3} - 3$

Step-by-step explanation:

Let here the given function f(x) = y

or, $x= f^{-1} (y)$

⇒ y = 3x+ 9

Now, solving for x, we get

3x+ 9 = y ⇒ 3x = y - 9

or, $x = \frac{y-9}{3} = \frac{y}{3} - \frac{9}{3}$

⇒ $x = ( \frac{y}{3}) - 3$

Now, substituting x and y

Hence, $f^{-1} (x) = \frac{x}{3} - 3$
