In 1992, there were 120 students in the freshmen class. in 2005, there were 224. find the rate of change from 1992 to 2005.

answers given are: a) -1/8 b)8 c)-8 d)1/8

me and show all work. : )

b) 8

they were asking you about the rate of increase in students per year

so you take increase in students/years= (224-120)/(2005-1992)=104/13=8

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1
