Answer:
One root of f(x) = x³ + x² - 22x - 40 is 5. If 5 is a root of the function, then
✔ x - 5
is a factor.
The result of dividing (x3 + x2 – 22x – 40) by
(x – 5) is x2 + 6x + 8. Select all of the factor(s) of x2 + 6x + 8.
✔ (x + 4)
✔ (x + 2)
The completely factored form of the polynomial is f(x) =
✔ (x – 5)(x + 2)(x + 4)
Explanation:
Answer:
<u>x = 7</u>
Explanation:
Because 25 is a perfect square of 5, we can turn
= ![25^{x + 1}](https://tex.z-dn.net/?f=25%5E%7Bx%20%2B%201%7D)
into
= ![5^{2x + 2}](https://tex.z-dn.net/?f=5%5E%7B2x%20%2B%202%7D)
Since the bases are now both equal, we can completely ignore them, as we are only trying to find x. This leaves us with:
3x - 5 = 2x + 2
All we have to do now is solve for x:
x - 5 = 2 <em>Subtract 2x from both sides.</em>
<u>x = 7</u> <em>Add 5 to both sides.</em>

It is important to note that the direct of flow of the electricity current in the Linear Machine is anti-clockwise direction. The resultant effect of this is such that is stand at variance with the change in flux as force is going the right direction. See attached Image (Illustration I).
<h3>What is the magnitude of the current?</h3>
Recall that Force (f) = il xB
Given that Force (F) = 10N; and
Magnetic Field Density B = 0.5T
Hence,
10 = i x 0.2 x 0.5
[Note that Width is converted to Meters from millimeters that is 200 mmm = 0.2m]
10 = 0.1i
i = 10/0.1
i = 100A
<h3>
What is the Induced Voltage Across the metal bar?</h3>
Note that Vg = Vde + IR
Vg = 10 + 100 x 0.05
Vg = 10 + 5
Vg = 15v
<h3>
What is the final speed of the metal bar?</h3>
The final speed of the bar is given as V
Recall that Induced Voltage is VB x L
That is:
15 = V x 0.5 x 0.2;
15 = 0.1 V
make V the subject of the formula:
V = 15/0.1
V = 150m/s
<h3>
What is the status of the Machine? a motor or generator?</h3>
Given that the current being supplied is in DC hence the machine is a generator. [Vdc x i]
<h3>What is the electric power of the source?</h3>
The electric power of the source is:
Vdc x i
= 10 x 100
= 1,000 watts

The teaching intervention that the nurse would have to include would be to give the patient prescribed insomnia during dinner.
<h3>What is insomnia?</h3>
Insomnia is the term that is used to refer to the fact that a person is having issues with sleeping.
This may be due to underlying issues with health or with mental health. The patient can be helped by giving them prescribed pills that may help them to sleep.
In other to help the person that is suffering from this condition, A nurse would help them through the use of prescribed pills. The issue is that there are usually a lot of side effects when it comes to the use of pills to treat insomnia in a person.
Another way is through the use of sleep therapy to get them to readjust their sleep pattern. If this condition persists, it could be a cause for alarm for the patient.

Sorry but i really don't understand that question
