Answer:
Step-by-step explanation:
5. x/7 = 9/x
x^2 = 63
x= 3
6. x/84 = 16/x
x^2 = 1344
x=8
7. x/12 = 12/16
16x=144
x=9
8. x/48 = 48/64
64x=2304
x=36
Answer:
Absolute minimum = 1.414
Absolute maximum = 2.828
Step-by-step explanation:

For absolute minimum we take the minimum values of
and
.

Plugging in the minimum values in the function.

Absolute minimum value will be always positive.
∴ Absolute minimum = 1.414
For absolute maximum we take the maximum values of
and
.

Plugging in the maximum values in the function.

Absolute maximum value will be always positive.
∴ Absolute maximum = 2.828

We convert degrees to radian by multiplying by (
)
= (345) × (
)
= (
) × (π)
= 1.9166π
= 1.9166 × 3.14
= 6.018 rad
≈ 6.02 rad
