Suppose bug B lands on the end of the wiper blade closest to the pivot. Assume the wiper turns through an angle of 120°. In one

adelina 88 [10]

Answer:

s = 8*π in

Step-by-step explanation:

Given:

- The complete data is given in the figure (attached):

Solution:

- The bugs lands on the end of the wiper blade closest to the pivot. The arc length (s) swept by a wiper in one cycle i.e θ = 120° would be given by:

s = 2*r*θ

- Where, r: The distance between the bug and the pivot = 6 in

θ : Angle swept in radians

- The distance travelled by the bug is s:

s = 2*(6)*( 120 / 180 ) * π

s = 8*π in

Please help with this I am completely stuck on it

vaieri [72.5K]

Answer:

$f(x)=\sqrt[3]{x-4} , g(x)=6x^{2}\textrm{ or }f(x)=\sqrt[3]{x},g(x)=6x^{2} -4$

Step-by-step explanation:

Given:

The function, $H(x)=\sqrt[3]{6x^{2}-4}$

Solution 1:

Let $f(x)=\sqrt[3]{x}$

If $f(g(x))=H(x)=\sqrt[3]{6x^{2}-4}$ , then,

$\sqrt[3]{g(x)} =\sqrt[3]{6x^{2}-4}\\g(x)=6x^{2}-4$

Solution 2:

Let $f(x)=\sqrt[3]{x-4}$ . Then,

$f(g(x))=H(x)=\sqrt[3]{6x^{2}-4}\\\sqrt[3]{g(x)-4}=\sqrt[3]{6x^{2}-4} \\g(x)-4=6x^{2}-4\\g(x)=6x^{2}$

Similarly, there can be many solutions.
