The corrosion of a certain metallic substance has been studied in dry oxygen at 500 degrees centigrade. in this experiment the gain in weight after various periods of exposure was used as a measure of the amount of oxygen that had reacted with the sample. the table presents the data:
percent gain
1.0 .02
2.0 .03
2.5 .035
3.0 .042
3.5 .05
4.0 .054
a. plot a scatter diagram.
b. fit a linear solution.
c. predict the weight gain when the metal is exposed for 3.2 hours.

() at a farm, animals are fed bales of hay and buckets of gain.each bale of hay is in the shape of a rectangular prism.the base side lengths 2 feet and 3 feet,and the height is 5 feet. each bucket of grain is a cylinder with diameter of 3 feet. the height of the bucket is 5 feet as the height of bale. a. which is larger in area, the rectangular base of the bale or the circular base of the bucket? explain how you know b. which is larger in volume, the bale or the bucket? explain how you know

Write an equation for the function that includes the points (2,100)and (3,100)

Write a description of each inequality. 1. -5a + 3 > 1 2. 27 - 2b < -6 (this < has a _ under it) 3. 1/2 (c + 1) > 5 (this > has a _ under it)
