What is 10 x 3 1/6 awnser plz

BARSIC [14]

The easiest way to do this is to convert both of the numbers to improper fractions. so 10 becomes 10/1 and 3 1/6 becomes 19/6. Then we multiply straight across so 10*19 is 190 and 1*6 is 6 and we get 190/6. This can be simplified to 95/3 which is 31 2/3. Hope this helps.

We must use substitution to do this second integral. We can use the substitution t = 7x, which will give dx = Correct: Your answ

Answer:

Therefore, the solution is:

$\boxed{\int \sin 7x\, dx=-\frac{\cos 7x}{7}}$

Step-by-step explanation:

We calculate the given integral. We use the substitution t = 7x.

$\int \sin 7x\, dx=\begin{vmatrix} 7x=t\\ 7\, dx=dt\\ dx=\frac{dt}{7} \end{vmatrix}\\\\=\int \sin t \cdot \frac{1}{7}\, dt\\\\=\frac{1}{7}\cdot (-\cos t)\\\\=-\frac{\cos 7x}{7}$
