Answer:

(1/2)sin(2x) + C

Step-by-step explanation:

$y=2x\\\frac{dy}{dx} =2\\\ dx=\frac{dy}{2} \\\int\limits {cos 2x} \, dx \\\int\limits {cos(y) } \, \frac{dy}{2} =\frac{1}{2} \\\int\limits {cos(y) } \, dy=\frac{1}{2}sin(y) \\ substitute / y=2x\\\int\limits {cos 2x} \, dx = \frac{1}{2}sin(2x) +C$

(05.05)On a coordinate plane, the coordinates of vertices R and T for a polygon are R(−6, 2) and T(1, 2). What is the length of

ICE Princess25 [194]

Answer:

The length of Side RT of the polygon is $7\ units$

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

we have

$R(-6,2)\\T(1,2)$

substitute the values

$d=\sqrt{(2-2)^{2}+(1+6)^{2}}$

$d=\sqrt{(0)^{2}+(7)^{2}}$

$dRT=7\ units$
