given that m=8-5/r
1.make r the subject of the relation
2.find the value of r when s=7m=2 and 3=3​

Answers

Answer 1

Explanation:

Given that,

[tex]m=8-\dfrac{5}{r}[/tex]

(1) We need to find the value of r.

Subtract 8 from both sides,

[tex]m-8=8-8-\dfrac{5}{r}\\\\m-8=-\dfrac{5}{r}\\\\r(m-8)=-5\\\\r=\dfrac{-5}{(m-8)}[/tex]

So, the value of r is equal to [tex]\dfrac{-5}{(m-8)}[/tex].

(2) Put m=2 in the value of r. So,

[tex]r=\dfrac{-5}{(2-8)}\\\\r=\dfrac{5}{6}[/tex]

Hence, this is the required solution.

Residents who are unconscious may still be able to?

Answers

Unconscious residents may be able to hear. Hearing is the last sensory function a resident loses. Talk to the resident just as you would if they were alert.

While unconscious individuals might not be able to react or speak normally, they might still be able to process sensory data and have bodily reactions.

For instance, individuals can retract a limb when touched or show reflexive reactions to pain or stimulation. Additionally, a comfortable and relaxing setting, relaxing noises, and the presence of familiar voices or loved ones may be beneficial to unconscious residents since they can provide them a sense of safety and security.

Even if the patient is unable to actively engage or vocally express themselves, it is crucial for healthcare professionals and carers to offer compassionate and appropriate care, keep a calm environment, and make sure the patient's bodily requirements are addressed.
