The Black Hills of South Dakota is an example of an eroded "batholith".

Magma does not generally achieve the surface. In the event that gas weights are not sufficiently extraordinary to constrain the magma to the surface, or if overlying rocks can't be infiltrated by it, the magma may gradually cool and frame an extensive pool of stone. Stone is effortlessly unmistakable by its extensive gem structure and blend of minerals, including light-hued quartzes and darker feldspars and micas. An expansive district of intru-sive molten shake, found profound inside the outside, is known as a batholith. Batholiths can frame the center of a mountain run. This batholith, once framed profound inside Earth's outside layer, is presently uncovered at an elevation surpassing 3300 meters (10,000 ft) above ocean level. The Black Hills of South Dakota are another exemplary case of this sort of geologic development.

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

hence option (b) is correct.
