The graph models the amount of radioactive element present over the cours of a 2 minute experiment. What is the avearge rate of change of the amount of the element over the 2 minute experiment?

a -12.5 g/min
b 2 g/min
c. 2.5 g/min
d. -3.75 g/min

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:

the ratios are reciprocals im positive

step-by-step explanation:

they are all positive numbers so it wouldn't be the other ones

y=-2x+1500

step-by-step explanation:

+1500

2 over one

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex
