Suppose that F′(x)=f(x) and G′(x)=g(x). Which statements are true? A. If F and G differ by a constant, then f=g. B. If f and g d

Ksju [112]

Answer: The correct option is

(A) If F and G differ by a constant, then f = g.

Step-by-step explanation: According to the given condition, we have

$F'(x)=f(x)~~~\textup{and}~~~G'(x)=g(x).$

We are to select the correct statement.

Let F(x) = p(x) and G(x) = p(x) + c, c - constant.

Then, we get

$F'(x)=p'(x)~~~\textup{and}~~~G'(x)=p'(x).$

Therefore,

$F'(x)=G'(x)\\\\\Rightarrow f(x)=g(x)\\\\\Rightarrow f=g.$

Thus, if F and G differ by a constant, then f = g.

Option (A) is CORRECT.

Are 1/2 and 12/24 and 13/26 equivalent?

vesna_86 [32]

Yes because 12 is a half of 24 and 13 is a half of 26 which all equal to 1/2 . So the answer is YES

At what point on the paraboloid y = x2 + z2 is the tangent plane parallel to the plane 3x + 2y + 7z = 2? (if an answer does not

Nikitich [7]

If $f(x, y, z) = c$ represent a family of surfaces for different values of the constant $c$ . The gradient of the function $f$ defined as $\nabla f$ is a vector normal to the surface $f(x, y, z) = c$ .

Given <span>the paraboloid

$y = x^2 + z^2$ .

We can rewrite it as a scalar value function f as follows:

$f(x,y,z)=x^2-y+z^2=0$

The normal to the </span><span>paraboloid at any point is given by:

$\nabla f= i\frac{\partial}{\partial x}(x^2-y+z^2) - j\frac{\partial}{\partial y}(x^2-y+z^2) + k\frac{\partial}{\partial z}(x^2-y+z^2) \\ \\ =2xi-j+2zk$

Also, the normal to the given plane $3x + 2y + 7z = 2$ is given by:

$3i+2j+7k$

Equating the two normal vectors, we have:
</span>
$2x=3\Rightarrow x= \frac{3}{2} \\ \\ -1=2 \\ \\ 2z=7\Rightarrow z= \frac{7}{2}$

Since, -1 = 2 is not possible, therefore there exist no such point <span>on the paraboloid $y = x^2 + z^2$ such that the tangent plane is parallel to the plane 3x + 2y + 7z = 2</span>.
