400$ is fivided between kas, jaspar, and jae so that kas has twice as much as jaspar and jaspar has three times as much as jae.
Fynjy0 [20]

Let jae have x dollars. Thus, we can make the  equation:-

x + 3x + 2*(3x) = 400

4x + 6x = 400

10x = 400

x = 40

So jae has  $40 and

jaspar has 3x =  3* 40

= $120 dollars  (answer

(Step to step work)<br><br> sin x(cotx + tanx)
11Alexandr11 [23.1K]

solving sin(x)(cot(x) + tan(x)) we get sec(x)

Step-by-step explanation:

We need to solve: sin(x)(cot(x) + tan(x))

Solving:

We know:

cot(x)=\frac{cos(x)}{sin(x)}\\ and\,\,tan(x)=\frac{sin(x)}{cos(x)}

Putting the values of cot(x) and tan(x):

sin(x)(cot(x) + tan(x))\\=sin(x)(\frac{cos(x)}{sin(x)}+\frac{sin(x)}{cos(x)})

Taking LCM:

=sin(x)(\frac{cos(x)cos(x)+sin(x)sin(x)}{sin(x)cos(x)})\\=sin(x)(\frac{cos^2(x)+sin^2(x)}{sin(x)cos(x)})

We know that: cos^2x+sin^2x=1

and using identity: cos(x)sin(x)=sin(2x)*1/2

=sin(x)(\frac{1}{sin(2x)\frac{1}{2}})\\=sin(x)(\frac{2}{sin(2x)})

Using identity: sin(2x)=2cos(x)sin(x)

=sin(x)(\frac{2}{2sin(x)cos(x)})\\Cancelling\,\,same\,\,terms\,\,in\,\,numerator\,\,and\,\,denominator:\\=\frac{1}{cos(x)} \\=sec(x)

So, solving sin(x)(cot(x) + tan(x)) we get sec(x)

Where are the astmptotes for the following function located f(x)=7/x^2-2x-24​
ira [324]

Answer:

Hence, the asymptotes of f(x) located at x=6 and x=-4.

Step-by-step explanation:

Since we have given that

f(x)= \frac{7}{x^2-2x-24}

We need to find the asymptotes for the above function:

Asymptotes occur when denominator becomes zero.

x^2-2x-24=0\\\\x^2-6x+4x-24=0\\\\x(x-6)+4(x-6)=0\\\\(x-6)(x+4)=0\\\\x=6,-4
