Sofia takes 10mg of a medicine whose concentration in blood decreases by a factor of one half every day. Let t be the number of

days since Sofia took the medication. The amount of medication in her system after t days is S = 10(½)t.
Four days later, Lexi takes 10mg of the same medicine. How much medication, L, is in Lexi’s system on day t?

L = 10(1/2)t

L = 10(1/2)t + 4

L = 10(1/2)t – 4

L = 10(1/2)4t

Answer:

L = 10(\frac{1}{2} )^{t-4}

Step-by-step explanation:

If t is the number of days since Sofia took the medication of 10 mg, then the amount of medication in her system after t days will be S = 10(\frac{1}{2} )^{t}.

So, the concentration of medicine in blood decreases by a factor of one half every day.

If we count the number of days from today and Lexi takes 10 mg of the same medicine four days later then the amount of medicine left on her body after t days will be L = 10(\frac{1}{2} )^{t-4}. (Answer)

Find the indicated limit, if it exists. (1 point) limit of f of x as x approaches 9 where f of x equals x plus 9 when x is less
Sunny_sXe [5.5K]

Answer:

Step-by-step explanation:

For the limit of a function to exist, then the right hand limit of the function must be equal to its left hand limit as shown;

If the function is f(x), for f(x) to exist then;

\lim_{n \to a^{+} } f(x) =  \lim_{n \to a^{-} } f(x) =  \lim_{n \to a } f(x)

Given the function;

f(x) = \left \{ {{x+9\ x

Lets check if the above statement is true.

The right hand limit of the function occurs at x> 9

f(x) = 9-x

\lim_{x \to 9+} (9-x)\\= 9-9\\= 0

The left hand limit occurs at x<9

f(x) = x+9

\lim_{x \to 9^{-} } (x+9)\\= 9+9\\= 18

From the above calculation, it can be seen that \lim_{x \to 9^{+} } f(x) \neq   \lim_{x \to 9^{-} } f(x), this shows that the function given does not exist at the given point.

What equations is equivalent to y = log x
saw5 [17]

"log" standing alone actually means "logarithm to the base 10."


Thus, y = log x   <=>   y = log      x
                                               10
                                                                           y
 Stated another way (inverse functions), x = 10

I think it is option A. Order matters; if the order is interchanged, the position of the figure will most likely change. You can try it out yourself too! Hope I helped! Happy Holidays!
