WILL GIVE BRAINLIEST!!! Find the length of DF

Leto [7]

Answer:

190.4

Step-by-step explanation:

Solve the following system:

{2 y - 3 x - 8 = 3 y + 4 x - 1 | (AB=DE)

4 y + 10 x + 3 = -2 y - 17 x + 9 | (BC=EF)

x = -16/5, y = 77/5

DF=AC=-27x+5y+27=190.4

There you go, have a great day

Order: give Ceclor (cefaclor) 250 mg PO every 8 hours.

irinina [24]

Hello!

The answer is: 15 mL

Why?

From the statement we have that 250 mg need to be given every 8 hours, we can calculate how many mg will be given each day (24 hours):

$\frac{24Hours}{8Hours} = 3$

So,

$3*250mg=750mg$ a day

We also know that there are 50 mg cefaclor every 1mL,

So, to know how many mL will be given with 750mg, we just need to divide it by 50

$\frac{750}{50} = 15$

Therefore,

15mL or 750 mg of cefaclor will be given each day.

Have a nice day!

Determine whether the series is convergent or divergent by expressing sn as a telescoping sum (as in Example 8). [infinity] 6 n2

vekshin1

Answer:

Step-by-step explanation:

given

$\sum\limits^\infty_{n=3}\frac{6}{n^2-1}=\sum\limits^\infty_{n=3}\frac{6}{(n-1)(n+1)}\\\\=\sum\limits^\infty_{n=3}\frac{6}{2}(\frac{1}{n-1}-\frac{1}{n+1})\\\\=\frac{6}{2}\sum\limits^\infty_{n=3}(\frac{1}{n-1}-\frac{1}{n+1})\\\\=3[(\frac{1}{2}-\frac{1}{4})+(\frac{1}{3}-\frac{1}{5})+(\frac{1}{4}-\frac{1}{6})+(\frac{1}{5}-\frac{1}{7})+...]\\\\=3[\frac{1}{2}+\frac{1}{3}]=3[\frac{3+2}{6}]=3[\frac{5}{6}]\\\\=\frac{15}{6}=\frac{5}{3}$
