We must add 2/3 and 2/7.
We have to convert these to fractions with "21" as the denominator.
14/21 plus 6/21 =
20/21 of the quizzes have been corrected.

You take a 200 milligram dosage of aspirin. During each subsequent hour, the amount of medication in your bloodstream decreases
shepuryov [24]

Answer: The level of aspirin (mg) will be in your bloodstream in 4 hours = 35.70 mg.

Step-by-step explanation:

If the amount is decreasing by r%, then the final amount is given by :-

A=P(1-r)^t

, where P = initial value , t= time

Given: P= 200 milligram, r= 35% = 0.35, t= 4 hours

The level of aspirin (mg) will be in your bloodstream in 4 hours = 200(1-0.35)^4

=200(0.65)^4\\\\=200\times 0.17850625\\\\=35.70125\approx35.70 \ mg

Hence, the level of aspirin (mg) will be in your bloodstream in 4 hours = 35.70 mg.

Pleas help me find the composition of goh and it’s domain
Ksivusya [100]

Solution:

The function is given below as

\begin{gathered} g(x)=\frac{x+4}{x-1} \\ h(x)=2x-1 \end{gathered}

To figure out

(goh)(x)

To do this , we will substitute x= 2x-1 in g(x)

\begin{gathered} g(x)=\frac{x+4}{x-1} \\ g(h)(x)=\frac{2x-1+4}{2x-1-1} \\ g(h)(x)=\frac{2x+3}{2x-2} \end{gathered}

Hence,

The composte function will be

(goh)(x)=\frac{2x+3}{2x-2}

Step 2:

To figure out the domain,

In mathematics, the domain of a function is the set of inputs accepted by the function.

Hence,

The domain of the function is

\begin{bmatrix}\mathrm{Solution:}\:&\:x1\:\\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:1\right)\cup \left(1,\:\infty \:\right)\end{bmatrix}

0.25 times 3.00 is 0.75 
minus 0.75 to 3.00 and it will be 2.25
0.20 times 2.25 will be 0.45
minus 0.45 to 2.25 
and u will get 1.80
