May I plz get some help plz
mr_godi [17]

Step-by-step explanation:

5x +10° + 58° = 11x + 2°( Exterior angle of a triangle is equal to the sum of two opposite interior angles)

5x + 68° = 11x + 2°

11x - 5x = 68° - 2°

6x = 66°

x = 66° / 6

Therefore x = 11°

Hope it will help you :)

Which of the following rules is the composition of a dilation of scale factor 2, then a translation of three units to the right?
SIZIF [17.4K]

Answer:

The answer is C: (2x +3, 2y)

Step-by-step explanation:

When applying the dilation of a scale factor of 2, you have to apply it to both the x and y coordinate, which means you are multiplying the coordinates by 2.

Let's assume the coordinates you start with are (x, y). Apply the dilation of 2.

(x, y) -----> (2x, 2y)

Now you are moving the figure right. When moving right, this only effects the x coordinate since the x axis moves left and right. Moving right indicates you will add the number of units translated to the x coordinate.

Translation 2 units right:

(2x, 2y) -----> (2x +3, 2y)

Please help me to solve this ∫ 1/(x + √x) dx
skad [1K]

Answer:

\boxed{2ln (\sqrt{x}  + 1 ) + c}

Step-by-step explanation:

\int\limits {\frac{1}{x + \sqrt{x} } } \, dx

= \int\limits {\frac{1}{\sqrt{x} (\sqrt{x}  + 1 )} } \, dx

= \int\limits {\frac{2}{(\sqrt{x}  + 1 )} } \, d(\sqrt{x}  + 1 )

= 2ln (\sqrt{x}  + 1 ) + c
