Crater lake oregon is a roughly circular lake. the lake basin formed about 7000 years ago when the top of a volcano exploded in an immense explosion. hillman peak, garfield peak, and cloudcap are three mountain peaks on the rim of the lake. the peaks are located in a coordinate plane at h(-4,1), g(-2,-3), and c(5,-2). find the coordinates of the center of the lake.

The coordinates of the center of the lake are .

Step-by-step explanation:

It is given that Hillman Peak, Garfield Peak, and Cloudcap are three mountain peaks on the rim of the lake. The peaks are located in a coordinate plane at H(-4,1), G(-2,-3), and C(5,-2).

If we joint these points, then we get a triangle and the center of a triangle is known as centroid.

The formula for centroid of a triangle is

The centroid of the triangle H(-4,1), G(-2,-3), and C(5,-2) is

Therefore the coordinates of the center of the lake are .

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
