\int {\frac{3}{\sqrt{1-4x^{2}}}} \, dx
= 3\int {\frac{1}{\sqrt{1-4x^{2}}}} \, dx
= 3\int {\frac{1}{\sqrt{4(\frac{1}{4} - x^{2})}}} \, dx
= \frac{3}{2}\int {\frac{1}{\sqrt{\frac{1}{4} - x^{2}}}}\, dx

= \frac{3}{2}sin^{-1}(2x) + C

PLEASE HELP ME What is the measure of angle y?<br> 130°<br> 50°<br> 90°<br> 40°
QveST [7]

Answer:

m<y=50

Step-by-step explanation:

The total interior angles of a triangle is 180 degrees. This is a right triangle, the right angle measures 90 degrees. The given angle is 40 degrees.

Add 90 and 40.

90+40=130

Subtract 130 from 180.

180-130=50

m<y=50

Check:

90+40+50=180

90+90+180

180=180
