Find the 52nd term of the given arithmetic sequence-30, -38, -46, -54...

torisob [31]

The sequence is given to be:

$-30,-38,-46,-54...$

The nth term of an arithmetic sequence is calculated using the formula:

$a_n=a_1+(n-1)d$

where a₁ is the first term, n is the number of terms, and d is the common difference.

From the given sequence, the following parameters can be gotten:

$\begin{gathered} a_1=-30 \\ d=-38-(-30)=-8 \end{gathered}$

Therefore, the parameters can be substituted into the formula to find the 52nd term:

$\begin{gathered} n=52 \\ \therefore \\ a_{52}=-30+(52-1)(-8) \\ a_{52}=-30+51(-8)=-30-408 \\ a_{52}=-438 \end{gathered}$

The 52nd term is -438.

The MD orders 50mg of an elixir to be given every 12 hours. Available is 125mg/5ml. How much should be administered every 12 hou

Jet001 [13]

FORMULA

D ( desired dose) x V ( vehicle- tablet or liquid)

H ( dose on hand)

D = Dose ordered

H = dose on hand or dose on container label

V = form and amount in which drug comes ( tablet, capsule, liquid)

D= 50mg H= 125mg V= 5ml

50 x 5

125

250 divided by 125 = 2ml

So, 2ml of elixir is administered every 12 hours :) brainliest pls

Answer:

Step-by-step explanation:

given that you look over the songs in a jukebox and determine that you like 14 of the 52 songs

Here each song is independent of the other song

i.e. p = Probability that you like any song = $\frac{14}{52} =0.2692$
