Wendell is looking over some data regarding the strength, measured in Pascals (Pa), of some building materials and how the strength relates to the length. The data are represented by the exponential function f(x) - 2 where x is the length. Explain how he can convert this equation to a logarithmic function when strength is 8 Pascals

The graph shows the prices of different numbers of bushels of corn at a store in the current year. the table shows the prices of different numbers of bushels of corn at the same store in the previous year. previous year number of bushels price of corn (dollars) 2 10 4 20 6 30 8 40 part a: describe in words how you can find the rate of change of a bushel of corn in the current year, and find the value. part b: how many dollars more is the price of a bushel of corn in the current year than the price of a bushel of corn in the previous year? show your work.

Solve the system of equations. y= 2x y= x^2 - 15

Which shows the correct substitution of the values a,b and c from the equation 1=-2x+3x^2+1
