urgenttttt What is the value of x? A right triangle has a vertical hypotenuse labeled 6. A 30 degree angle is marked at the top
Anni [7]

Answer:

x=30degrees

Step-by-step explanation:

the diagram, if drawn comes as a square. when divided to two triangles, both of them have one right angle each. if the hypotenuse is thirty d on one side, the opposite angle has to be 60d . since the total of all angles is 180d and one side is 90d and the other 60d, the other angle must me 30d

HELP ME TO ANSWER THIS PLEASE JUST KINDA CONFUSED.
yulyashka [42]

Answer:

A = 5

B = 9

Step-by-step explanation:

This was very simple!

Nancy needs at least 15 boxes of travoprost but she only has 10. To find out how many she needs, we subtract 15 from 10 to get 5 boxes

Nancy also needs at least 12 boxes of latanoprost but she only has 3. To find out how many she needs, we subtract 12 from 3 to get 9 boxes

Therefore A = 5 boxes; B = 9 boxes

How do I evaluate this integral?<img src="https://tex.z-dn.net/?f=%20%5Cint%5Climits%20%7B%20%5Cfrac%7Bx%7D%7Bx%5E4%2B1%7D%20%7D

One thing you could try is to set x=\sqrt y. This makes y=x^2, so that \mathrm dy=2x\,\mathrm dx, and y^2=x^4. So the integral is

\displaystyle\int\frac x{x^4+1}\,\mathrm dx=\frac12\int\frac{\mathrm dy}{y^2+1}=\frac12\arctan y+C=\frac12\arctan(x^2)+C

A "trickier" way to do it is to write

x^4+1=(x^2+\sqrt2x+1)(x^2-\sqrt2x+1)

so you could decompose the integrand into partial fractions. But that's more work than needed.
