You can calculate the arc lenght by using this formula: 
arc length = 2π*r*(A/360) , where A=angle of the arc. 

So for you it would be: 
arc length = 2π*4*(72/360) = 5.03

I hope that helped.

yuradex [85]
40,000,000

Standard form means that you are just writing out the numbers regularly. In this case, we are switching from scientific notation to standard. The 10 is raised to the 7th power, so we have to move the decimal 7 places to the right.

Please help quarter ends tomorrow and I don’t know what to do I’m failing all my classes
Nutka1998 [239]

Step-by-step explanation:

x = -10, y = 10

y= -4x+4

m1×m2 = -1

-4 × m2 = -1

m2 = 1/4

y-y1 = m(x-x1)

y-10 = 1/4(x+10)

y-10 = 1/4x +10/4

(×4)

4y-40=x+10

4y=x+50

x-4y+50=0
