Answer:

x= -13

Step-by-step explanation:

Step-1 : Multiply the coefficient of the first term by the constant   1 • 13 = 13  

Step-2 : Find two factors of  13  whose sum equals the coefficient of the middle term, which is   14 .

     -13    +    -1    =    -14  

     -1    +    -13    =    -14  

     1    +    13    =    14    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  1  and  13  

                    x2 + 1x + 13x + 13

Step-4 : Add up the first 2 terms, pulling out like factors :

                   x • (x+1)

             Add up the last 2 terms, pulling out common factors :

                   13 • (x+1)

Step-5 : Add up the four terms of step 4 :

                   (x+13)  •  (x+1)

            Which is the desired factorization

Answer:

C) π/6

Step-by-step explanation:

The area under the curve from x=-π/2 to x=k is 3 times the area under the curve from x=k to x=π/2.

\int\limits^k_{-\frac{\pi }{2}} {cos\ x} \, dx = 3\int\limits^{\frac{\pi }{2}}_k {cos\ x} \, dx\\sin\ x\ |^{k}_{-\frac{\pi }{2}} = 3\ sin\ x\ |^{\frac{\pi }{2}}_k\\(sin\ k - (-1)) = 3\ (1 - sin\ k)\\sin\ k + 1 = 3 - 3\ sin\ k\\4\ sin\ k = 2\\sin\ k = \frac{1}{2}\\k = \frac{\pi}{6}

Two supplementary angles are in the ratio of 31:5 find angles​
ad-work [718]

Answer:

The angles are <u>155°</u> and <u>25°</u>.

Step-by-step explanation:

Given:

Two supplementary angles are in the ratio of 31:5.

Now, to find the angles.

The sum of two supplementary angles = 180°

Let the ratio of the angles be 31x\ and\ 5x.

So, according to question:

31x+5x=180\°

36x=180\°

<em>Dividing both sides by 36 we get:</em>

x=5

So, 31x=31\times 5=155\°.

And, 5x=5\times 5=25\°.

Therefore, the angles are 155° and 25°.
