Answer 1

Answer: 6.3093

Explanation:

`3^{(x)/(5)} = 4`

`ln3^{(x)/(5)} = ln4`

`(x)/(5) ln3 = ln4`

xln3 = 5ln4

`x = (5ln4)/(ln3)`

x = 6.3093

Answer: 5, 3,
`(1)/(5)`, D

Explanation:

a) x ≤ 0 so, f(-5) = | -5 | = 5

x ≤ 0 so, f(-3) = | -3 | = 3

x > 0 so, f(5) =
`(1)/(5)`

b) graph D

Answer:
`(\pi)/(12)`

Explanation:

`(25\pi)/(12) - \frac{2\pi}{}`

=
`(25\pi)/(12) - (24\pi)/(12)`

=
`(\pi)/(12)`
