Situation: A 25 gram sample of a substance thats used for to sterilize surgircal instruments has a k-value of 0.1205. N=Noe^-kt

Naya [18.7K]

Going by the formula, Half-Life = ln(.5) / k
Half-Life = .693147 / .1205
Half-Life = 5.75 days and rounded to nearest tenth,
Half-Life = 5.8 days

Which of the following are solutions to the graph

jarptica [38.1K]

Answer:

F. $\displaystyle (2, 6)$

C. $\displaystyle (-1, 0)$

B. $\displaystyle (-2, -2)$

Step-by-step explanation:

You first need to find the linear equation [in Slope-Intercept Form of course] of this graph, which is $\displaystyle y = 2x + 2.$ To do this, starting from the y-intercept of $\displaystyle (0, 2),$ you do $\displaystyle \frac{rise}{run}$ by either moving two blocks south over one block way or two blocks north over one block east [west and south are negatives]. This will give you your rate of change [slope] of 2.

* $\displaystyle y = mx + b → Slope-Intercept Formula$
