1. Three points are collinear if they lie on the same line. The diagram shows two triples of points that lie on the same line:
points B, C and D;
points A, C and E.
Thus, option B is true.
2. Another way to name the plane is to select three points which do not lie on the same line and write them consequently. As you can see from the diagram, points B, F and D lie on the plane M, but do not lie on the same line. Thus, another way to name plane M is BFD.
so the volume is 287 radius is 5 . The formula Volume = base area x height which we come to equate 287 =3.142x5x5 to get 287 divides by 78.55 answers round off to the nearest tenths 3.653 round off 3.7
Basically what is happening is: You start out with 15. That 1st week you have 22% more than 15, or in other words 15*1.22. The following week you have 22% more than 22% more of 15, which is 15*1.22*1.22.
Now we can write a function that models this situation: f(n): number of views n: number of weeks since you started
f(n) = 15(1.22^n)
We want to find out how many views there are after four weeks, so plug 4 in for n. f(4) = 15(1.22^4) f(4) = 33.23
This means after 4 weeks you can expect the video to have 33 views.
Surface Area of the figure is 1208 square centimeters a=20 b=13 c=12 d=5 e=8 Top face: A1=a×e=20×8 ae=160 Bottom face: A2(a+2d)×e=(20+2×5)×8=(20+10)×8=30×8 (a+2d)e=240 Front face: Rectangle a×c=20×12=240 Triangle: 12c×d=12×12×5=6×5=30 A3Rectangle +2 triangles 240+2×30=240+60=300 (a+d)c=300 Slant face: A4=b×e=13×8=104 be=104 Total surface area A=A1+A2+2(A3+A4) A1=160 A2=240 A3=300 A4=104 Thus, A=160+240+2(300+104) A=400+2(404) A=400+808=1208 Surface Area of the figure is 1208 square centimeters
