Step-by-step explanation:

and yes... I can out to my bestfriend of over six years and after me telling her I wasn't ready to come our completely she outed me to several people without my permission. This resulted in her very religious mother telling my very religious father as well as many other people. It was not only hurtful but wrong. I got my phone taken along with many of my friends numbers that I lost causing me to struggle with my already diagnosed depression and anxiety being I am homeschooled and now have near to no social interaction at almost 15. I handled this situation by keeping my head up and looking at positive things which did come along, including me getting into an arts high school, me finding more ways to cope, and some other things. I am still upset but have chosen to get over the situation. I also still very gay though so them going through all that did nothing.

Nancy and Harry are sliding a stone statue and moving it to a new location in their garden. Nancy is pushing the statue with a f

Nimfa-mama [501]

Answer:

197,8879 N.

Step-by-step explanation:

The magnitude of the horizontal force exerted on the statue can be calculated using trigonometric functions.

The question given says that Nancy is pushing the statue with a force of 120 N at a 60° angle to the horizontal and Harry is pulling the statue with a force of 180 N at a 40° angle with the horizontal.

With that information can be calculated the horizontal force exerted on the statue by Nancy, the horizontal force exerted on the statue by Harry and, adding that results, the total horizontal magnitude can be calculated.

The cosine function can be used to calculate the horizontal component of the forces exerted by Nancy and Harry, to determine the horizontal component of the force exerted on the statue.

F= (120 N cos 60°) + (180 N x cos 40°)

F= 197,8879 N

Solve for p. 9(p-4) = -18 p=

agasfer [191]

Step-by-step explanation:

9(p-4) = -18

9p - 36 = -18

9p = -18 + 36

9p = 18

p= 18/9

p = 2

Check:

9 ( 2 - 4 ) = - 18

9 (-2) = - 18

- 18 = - 18
