Wait let me know that the .12 means in the first question and i will fix the answer

int (x)(cosx) dx

u=x ----> take derivative du=dx
dv=cosx -----> take integral v=sinx

now use integration by parts

u v - int (v)du
x sinx - int (sinx) (1) dx=

x sinx - (-cos(x)) + c =

answer is = x sinx + cosx + c

There are 9 seniors.

Although there are several ways of solving this problem, I just did what was easiest for me in my head. I divided 36 by 4, which gave me 9.

The points (1,2),(1,-3),and (5,-3) form a triangle on the coordinate plane. b. What is the perimeter of the triangle?

Alexeev081 [22]

The perimeter of the triangle is 13.56 units.

The perimeter of a shape on a coordinate plane is found by finding the distance between all points, and then adding them together. It's easier to write it out than to type so I'll attach a photo of my work.
