What are the period and phase shift for f(x) = 3 tan(4x + π)?

Y_Kistochka [10]

$\bf \qquad \qquad \qquad \qquad \textit{function transformations}
\\ \quad \\
% function transformations for trigonometric functions
\begin{array}{rllll}
% left side templates
f(x)=&{{ A}}sin({{ B}}x+{{ C}})+{{ D}}
\\ \quad \\

\end{array}$

$\bf \begin{array}{llll}
% right side info
\bullet \textit{ stretches or shrinks}\\
\quad \textit{horizontally by amplitude } |{{ A}}|\\\\
\bullet \textit{ horizontal or "phase" shift by }\frac{{{ C}}}{{{ B}}}\\
\qquad if\ \frac{{{ C}}}{{{ B}}}\textit{ is negative, to the right}\\
\qquad if\ \frac{{{ C}}}{{{ B}}}\textit{ is positive, to the left}\\
\end{array}$

$\bf \begin{array}{llll}


\bullet \textit{vertical shift by }{{ D}}\\
\qquad if\ {{ D}}\textit{ is negative, downwards}\\
\qquad if\ {{ D}}\textit{ is positive, upwards}\\\\
\bullet \textit{function period}\\
\qquad \frac{2\pi }{{{ B}}}\ for\ cos(\theta),\ sin(\theta),\ sec(\theta),\ csc(\theta)\\
\qquad \frac{\pi }{{{ B}}}\ for\ tan(\theta),\ cot(\theta)
\end{array}$

now.. with that template above in mind, let's see yours

$\bf \begin{array}{lllllll}
f(x)=&3tan(&4x+&\pi )\\
f(x)=&3tan(&4x+&1\pi )&+0\\
&\uparrow &\uparrow &\uparrow &\uparrow \\
&A&B&C&D
\end{array}$

A card is selected at random from a deck of 52 playing cards, the probability that a card 2 is selected will be ______________.

kkurt [141]

Answer:

b) 4/52

Step-by-step explanation:

Since there are only 4 playing cards in a full deck that are labeled '2', and there are 52 cards in total - then there is a 4 out of 52 chance that a '2' card will be selected!

Answer:

10²

Step-by-step explanation:

left triangle = 2 × 2 = 4 ÷ 2 = 2²

right triangle = 2 × 4 = 8 8 ÷ 2 = 4²

middle square = 2 × 2 = 4²

2 + 4 + 4 = 10²

Find BC the length not the angle<br><br><br>Round to the nearest tenth.

PSYCHO15rus [73]

Answer:

14.4

Step-by-step explanation:

We solve the above question using Cosine Rule

The formula is given as:

BC² = AB²+ AC²﹣2 × AB × AC cos A

BC² = 6² + 13²﹣2 × 6 × 13 × cos(91°)

BC = √6² + 13²﹣2 × 6 × 13 × cos(91°)

BC = 14.41258

Approximately

BC = 14.4
