1 hr 38 min

Step-by-step explanation:

The start time is 7:20. The end time is 8:58.

When 1 hour passes by, the time is 8:20.

8:58 - 8:20 = 38 minutes

Please help with this I am completely stuck on it

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.

The volume of a cylinder with height h h and radius r r can be found using the formula V = ? r 2 h V=?r2h Find the volume of a c

Pavel [41]

Answer:

5.000 ft

Step-by-step explanation:

The formula for the volume of a cylinder is

V = πr²h

Data:

V = 785.4 ft³

h = 2r

Calculations:

V = πr²h = πr²(2r) = 2πr³

Divide each side by 2π

$\frac{V }{2\pi } = r^{3}$

Take the cube root of each side

$r = \sqrt[3]{\frac{V }{2\pi}}$

$= \sqrt[3]{\frac{785.4 }{2\pi }}$

$= \sqrt[3]{125.00}$

= 5.000 ft

The radius of the cylinder is 5.000 ft.
