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

bazaltina [42]

Answer: Medication in Lexi's system on day t becomes,

$L=10.625(\frac{1}{2})^{t-4}$

Step-by-step explanation:

Since we have given that

Initial amount Sofia takes of a medicine = 10 mg

Concentration in blood decreases by a factor of one half every day.

So, it becomes,

$S=10(\frac{1}{2})^t\\\\here,\text{ t denotes number of days}$

According to question, four days later, it becomes,

$S=10(\frac{1}{2})^4\\\\S=\frac{10}{16}\\\\S=0.625\ mg$

We have given that Lexi takes 10 mg of the same medicine.

So, it becomes,

$10+0.625\\\\10.625\ mg$

Hence, Medication in Lexi's system on day t becomes,

$L=10.625(\frac{1}{2})^{t-4}$

NO LINKS!! Please help me with this Geometry part 15

The converse statement is; If I have two ears, then I am a bunny

The inverse statement is; "If I am not a bunny, then I don't have two ears."

The contrapositive statement is; If I don't have two ears, then I am not a bunny.

<h3>How to Interpret Conditional Statements?</h3>

A conditional statement is a statement that can be written in the form “If P then Q,” where P and Q are sentences

We are given the conditional statement;

If I am a bunny, then I have two ears

To form the converse of the conditional statement, we will interchange the hypothesis and the conclusion. The converse statement of "If it rains, then they cancel school" is expressed as "If they cancel school, then it rains."

Thus, the converse of our statement "If I am a bunny, then I have two ears." is;

If I have two ears, then I am a bunny

To form the inverse statement of the conditional statement, we will take the negation of both the hypothesis and the conclusion. The inverse of “If it rains, then they cancel school” is expressed as “If it does not rain, then they do not cancel school.”

Thus, the inverse of our statement "If I am a bunny, then I have two ears." is;

"If I am not a bunny, then I don't have two ears."

The contrapositive of our conditional statement is;

If I don't have two ears, then I am not a bunny.

Can x8 x y3 be written as a single power

NeX [460]

$x^{8} *y^{3}$ can only be written as $x^{8}* y^{3}$ or as $x^{8} y^{3}$ . One has the multiplication sign the other does not, which is why we put it together, because we know that if they are together they will be multiplied.
