Tan x= 3÷5 nearest tenth​

Mathematics
1 answer:
Daniel [21]4 years ago
4 0

Answer:

17.0°

Step-by-step explanation:

We want to solve

\tan(x)  =  \frac{3}{10}

We take inverse tangent of both sides using a scientific calculator to get:

x =  { \tan}^{ - 1} ( \frac{3}{10} )

x = 16.6992

We round to the nearest tenth to get;

x = 17.0 \degree

Therefore the value of x is 17.0°

(6+√-64)(3-√-16) Multiply. This is urgent, please explain this to me!
romanna [79]

Answer:

50

Step-by-step explanation:

\sqrt{-64} and \sqrt{-16} can be expressed in complex form, with \sqrt{-1} = i

\sqrt{-64} = \sqrt{64(-1)} = \sqrt{64} × \sqrt{-1} = 8i

\sqrt{-16} = \sqrt{16(-1)} = \sqrt{16} × \sqrt{-1} = 4i

the factors can then be expressed as

(6 + 8i)(3 - 4i) ← expand using FOIL

= 18 - 24i + 24i - 32i² [ i² = (\sqrt{-1} )² = - 1 ]

= 18 - 24i + 24i + 32 ← collect like terms

= 18 + 32 + 0

= 50
