What is the image of the point (-8,3)(−8,3) after a rotation of 270^{\circ}270

Mathematics

Given:

The point is (-8,3).

To find:

The image of the given point after a rotation of 270 degrees counterclockwise about the origin.

Solution:

If a point is rotated 270 degrees counterclockwise about the origin, then the rule of rotation is:

(x,y)\to (y,-x)

Using this rule, we get

(-8,3)\to (3,-(-8))

(-8,3)\to (3,8)

Therefore, the  image of the given point after a rotation of 270 degrees counterclockwise about the origin is (3,8).

Write the composite function in the form f(g(x)).[Identify the inner function u = g(x)and the outer function
Vadim26 [7]

Answer:

a) (g(x), f(u)) = ( 7*√x , e^u )

b)   y ' = 3.5 * e^(7*√x) / √x

Step-by-step explanation:

Given:

- The given function:

                                       y = e^(7*√x)

Find:

- Express the given function as a composite of f(g(x)). Where, u = g(x) and y = f(u).

- Express the derivative of y, y'?

Solution:

- We will assume the exponent of  the natural log to be the u. So u is:

                                     u = g(x) = 7*√x

- Then y is a function of u as follows:

                                     y = f(u) = e^u

- The composite function is as follows:

                                    (g(x), f(u)) = ( 7*√x , e^u )

- The derivative of y is such that:

                                    y = f(g(x))

                                    y' = f' (g(x) ) * g'(x)

                                    y' = f'(u) * g'(x)

                                    y' = e^u* 3.5 / √x

- Hence,

                                   y ' = 3.5 * e^(7*√x) / √x
