For the reaction M + X → 2 Y, determine the rate of change for the product Y if the rate of consumption for X is 3.8×10–4 M/s. Select the equation needed to determine the relative rate of change for X on the left and then calculate the rate of formation for Y on the right.

What is the value of f(x) = 2.2 for f(-2)?

M. xyz =radians. covert this radian measure to its equivalent measure in degrees.

Ariana starts with 100 milligrams of a radioactive substance. the amount of the substance decreases by 20% each week for a number of weeks, w. the expression 100(1−0.2)w finds the amount of radioactive substance remaining after w weeks. which statement about this expression is true? a) it is the difference between the initial amount and the percent decrease. b) it is the difference between the initial amount and the decay factor after w weeks. c) it is the initial amount raised to the decay factor after w weeks. d) it is the product of the initial amount and the decay factor after w weeks.
