sin alpha = 7/25, alpha lies in quadrant ii, and cos beta = 2/5, beta lies in quadrant i. find cos(alpha-beta).
Ilia_Sergeevich [38]

Answer:

Therefore \cos(\alpha-\beta)=\frac{48+7\sqrt{25}}{125}

Step-by-step explanation:

Given values are

\sin \alpha=\frac{7}{25}

\cos \beta=\frac{2}{5}

\sin^2x+\cos^2=1

\cos \alpha=\sqrt{1-\sin^2\alpha}

\cos \alpha=\sqrt{1-(\frac{7}{25})^2}

\cos \alpha=\sqrt{1-\frac{49}{625}}

\cos \alpha=\sqrt{\frac{576}{625}}

\cos \alpha=\frac{24}{25}

\sin \beta=\sqrt{1-\cos^2\beta}

\sin \beta=\sqrt{1-(\frac{2}{5})^2}

\sin \beta=\sqrt{1-\frac{4}{25}}

\sin \beta=\frac{\sqrt{21}}{5}

\cos(\alpha-\beta)=\cos\alpha\cos\beta+\sin\alpha\sin\beta

\cos(\alpha-\beta)=\frac{24}{25}\times\frac{2}{5}+\frac{7}{25}\times\frac{\sqrt{21}}{5}

\cos(\alpha-\beta)=\frac{48+7\sqrt{25}}{125}

What are the domain and range of the algebraic function you found by graphing the equation y = 36 – 3x? Please hurry I'm being t
pychu [463]

Answer:

Domain =(-\infty,\ \infty)

Range =(-\infty,\ \infty)

Step-by-step explanation:

Domain : Domain of a function f(x) is the set of all possible values of x for which f(x) exists.

Range : range of a function f(x) is the set of all possible values of f(x).

Here f(x)=36-3x

x can be any value from -\infty to \infty.

\forall\ x=a\ there\ exists\ f(x)\ such\ that\ f(a)=36-3a

hence possible value of x can be any value between -\infty and \infty

domain =(-\infty,\ \infty)

let y=-f(x)

y=36-3x\\3x=36-y\\\\\\x=\frac{36-y}{3}\\

so \forall\ f(x)=y\ there\ exist\ x\ \in(-\infty,\ \infty).

hence f(x) can have any value between -\infty\ to\ \infty..

Range =(-\infty,\ \infty)
