Answer:

B: 13

Step-by-step explanation:

we are given two points as

(2, - 12) and  (-11, - 12)

so,

x_1=2,y_1=-12

x_2=-11,y_2=-12

now, we can use distance formula

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

now, we can plug values

d=\sqrt{(-11-2)^2+(-12+12)^2}

d=\sqrt{(-11-2)^2+0}

d=13

So,

The distance is 13

Answer:

\sec x + c

Step-by-step explanation:

\int \frac{ \sin \: x}{ { \cos}^{2}x }  \: dx \\  \\  =  \int \frac{ \sin \: x}{ { \cos}x } . \frac{ 1}{ { \cos}x } \: dx \\  \\  =  \int  \tan x . \sec  x \: dx \\  \\  =  \sec x + c
