Half life can be used to solve for the amount (A) of a substance left after t time by using the following equation: A=A0⋅(12)th If the half life of a substance is 4 weeks, how long will it take for 400 mg of this substance to decay to 25 mg? Select one: A. 16 weeks B. 8 weeks C. 13 weeks D. 6 weeks

its d. the first coordintaes are 10,32

step-by-step explanation:

no this is a nonlinear negative

answer: 0,6

step-by-step explanation:

this would make it the y intercept.

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
