\cos \beta + \sin \beta \tan \beta \\\\= \cos \beta + (\tan \beta \cos \beta) \tan \beta \\\\=\cos \beta + \tan^2 \beta \cos \beta \\\\=\cos \beta( 1+ \tan^2 \beta)\\\\= \cos \beta \sec^2 \beta\\\\= \dfrac 1{\sec \beta} \times \sec^2 \beta \\\\= \sec \beta

Step-by-step explanation:

\cos( \beta  )  +  \sin( \beta )  \tan( \beta )  =  \sec( \beta )

\cos( \beta )  +  \sin( \beta )  \frac{ \sin( \beta ) }{ \cos( \beta ) }

\cos( \beta )  +  \frac{ \sin {}^{2} ( \beta ) }{ \cos( \beta ) }

\frac{ \cos {}^{2} ( \beta ) }{cos \beta }  +  \frac{ \sin {}^{2} ( \beta ) }{ \cos( \beta ) }

\frac{1}{ \cos( \beta ) }

=  \sec( \beta )

madam [21]

Answer:

The total for the housewife's purchase should be 60 dollars. So it should be the vender who owes her money. The vender owes her 15 dollars.

Step-by-step explanation:

$5 = 1kg (eddoes) meaning a total of 2kg eddos =$10

$10 = 1kg (chicken) meaning a total of 5kg chicken = $50

When added together, it'd be 60 dollars.

Find the distance between the given points (4,1) and (-5, -2)
anyanavicka [17]

Answer:

3\sqrt{10} units I THINK

Step-by-step explanation:

using the distance formula, -2 - 1 = -3

-3 x -3 = 9

-5 - 4 = -9 x -9 = 81

81 + 9 = 90

sqrt 90 simplified is 3\sqrt{10}.

so im pretty sure that's the answer.

How do I solve this graph
Sunny_sXe [5.5K]
Plug in two values for x, say, 0 and 1.  



Lets start with solving the equation when x=0.  

y=2(0)-3
y=0-3
y=-3.

So, when x=0, y=-3.  Graph (0, -3)

Next, x=1

y=2(1)-3
y=2-3
y=-1

So, when x=1, y=-1.  Graph (1,-1)

Draw a line between the two points, and that should be your answer!  Hope this helped :)
