Answer:  1) c    2) a     3) d

<u>Step-by-step explanation:</u>

\cos \theta = \dfrac{adjacent}{hypotenuse}\quad \\\\\\\cos 42.1=\dfrac{4.7}{x}\\\\\\x=\dfrac{4.7}{\cos 42.1}\\\\\\\large\boxed{x=6.33}\\

******************************************************************************************

Reference angle is the angle measurement from the x-axis.  <em>There is no such thing as a negative reference angle.</em>

-183°  is 3° from the x-axis so the reference angle is  \large\boxed{3^o}

*******************************************************************************************

Coterminal means the same angle location after one or more<em> </em>rotations either clockwise or counter-clockwise.

To find these angles, add <em>or subtract</em> 360° from the given angle to find one rotation, add <em>or subtract</em> 2(360°) from the given angle to find two rotations, etc.

To find ALL of the coterminals, add <em>or subtract</em> 360° as many times as the number of rotations.  Rotations can only be integers. In other words, you can only have ± 1, 2, 3, ... rotations. You cannot have a fraction of a rotation.

Given: 203°

Coterminal angles: 203° ± k360°, k ∈ <em>I</em>

Write:<br> 3^-4 in standard form
pav-90 [236]

Answer:

\frac{1}{81}

Step-by-step explanation:

<u>Key skills: Exponents + Fractions</u>

Use the negative exponent property. If your number is x^-y then it would be the same as 1/x^y

3^-4 is the same as \frac{1}{3^{4}}

3^4 is 81, so your answer would be 1/81.

Hope you have a nice day and understood this!
