Answer:
[[. . 3 6 .][1 3 4 9 .][9 2 . 7 1][. 1 2 8 3][. 4 9 . . ]]
Step-by-step explanation:
It is helpful to remember that the first four digits {1, 2, 3, 4} total 10, and the last four digits {6, 7, 8, 9} total 30. It is also worthwhile to note that the smallest sum of two digits is 3 = 1+2, and the largest sum of 2 digits is 17 = 8+9. Some sums can only be made one way: 4 = 1+3, 16 = 7+9.
Here, we will refer to rows 1-5 from the top down, and columns 1-5 from the left to right.
__
Based on the above, column 5 can only be made one way: 1+3. Column 4 can only be made one way: 9+8+7+6. Then the choices for row 3B will be 1+7 or 5+3. We know it can't be 5+3 because 5 is not part of column 4. This makes our first fill-in (row, column) be (3,4)=7, (3,5)=1, (4,5)=3.
The sum of the remaining cells in row 4 must be 14-3 = 11, and cell (4,4) must be 6, 8, or 9. It cannot be 9, because that would require the remaining two cells to have a sum of 2, which they cannot. So, cell (4,4) is 6 or 8.
Cell (1,4) cannot be 9, either, because we cannot use 0 in cell (1,3). Then the only place for 9 in column 4 is in cell (2,4)=9.
With cell (1,4) being restricted to 6 or 8 (the two remaining numbers in column 4, cell (1,3) must be 3 or 1, and cell (2,3) must be 4 or 6. It cannot be 6 because that would require a sum of 2 in the first two cells of row 2, so (2,3)=4, (1,3)=3, and (1,4)=6. This makes (4,4)=8 and the remaining two cells of row 4 must be 1 and 2. 1 cannot go in (4,3), so we must have (4,3)=2 and (5,3)=9, (5,2)=4, (4,2)=1. That leaves 2 and 3 for rows 2 and 3 of column 2. The first two cells of row 2 must total 4, so must be 1 and 3. Cell (2,2) cannot be 1, so must be 3, leaving (2,1)=1, (3,1)=9, (3,2)=2 and that completes it.
The fill-ins are ...
[. . 3 6 .]
[1 3 4 9 .]
[9 2 . 7 1]
[. 1 2 8 3]
[. 4 9 . . ]

Find the nth term for the following sequences, 100,96,90,82,72.(an^2+bn+c)
Answers

Answer:
t(n) = -n^2 -n +102
Step-by-step explanation:
We can use the first 3 terms to find a, b, c.
a(1)^2 +b(1) +c = 100
a(2)^2 +b(2) +c = 96
a(3)^2 +b(3) +c = 90
Subtract the first equation from the other two:
3a +b = -4 . . . . . . [eq4]
8a +2b = -10 . . . . [eq5]
[eq5] can be reduced to
4a +b = -5 . . . . . . [eq6]
Subtracting [eq4] from [eq6] gives ...
(4a +b) -(3a +b) = (-5) -(-4)
a = -1 . . . . . . . . simplify
Filling that into [eq4], we get
3(-1) +b = -4
b = -1 . . . . . . . add 3
Putting the values for 'a' and 'b' into the first equation gives ...
-1 +-1 +c = 100
c = 102
Then the n-th term t(n) of the sequence is ...
t(n) = -n^2 -n +102

How could you determine the coordinates of the vertices of a translated image without using a graph?
Answers
Using translation concepts, it is found that:
a) For a translation 6 units horizontally, 6 is either added or subtracted to the x-coordinate of the ordered pairs.
b) For a translation 3 units vertically, 3 is either added or subtracted to the y-coordinate of the ordered pairs.
c) The coordinates of the vertices of the translated image will be given according to the following rule: (x,y) -> (x ± 6, y ± 3).
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
For a translation 6 units horizontally, we have that:
If it is left, x -> x - 6.If it is right, x -> x + 6.Hence 6 is either added or subtracted to the x-coordinate of the ordered pairs.
For a translation 3 units vertically, we have that:
If it is down, y -> y - 3.If it is up, y -> y + 3.Hence 3 is either added or subtracted to the y-coordinate of the ordered pairs.
The coordinates of the vertices of the translated image will be given according to the following rule: (x,y) -> (x ± 6, y ± 3).

Step-by-step explanation:
the change rate is expressed by y/x (like the slope of a line).

17. ____________ Order: Penicillin, 350,000 U. Available: Penicillin, 400,000 U/5 mL.
How many mL will be administered to the patient per dose?
Answers
The ratio of mass required to concentration or rate gives the number of the units or time a medicine is to be administered
The quantities and time of medication are:
1. It will take 8 hours to infuse the fluid
2. The number of tsps is approximately 2 tsps
3. The maximum number of tablets is 6 tablets
4. The patient will receive 6 mL in 24 hours
5. The client will receive 32 capsules
6. 125 drops/minute per minute are needed so that the IV finishes
7. The volume of Penicillin per dose is 4.375 mL
The reason the above values are correct is as follows:
Required;
1. The volume of saline required to infuse, V = 1000 mL
The rate at which the saline is infused, r = 125 mL/hr
The number of hours it will take to infuse the fluid, t, is given as follows;
[tex]t = \mathbf{\dfrac{V}{r}}[/tex]
Therefore;
[tex]t = \mathbf{\dfrac{1000 \ mL}{125 \ \dfrac{mL}{hr} } = 8 \ hr}[/tex]
The number of hours it will take to infuse the fluid, t = 8 hours
2. The mass in the order, m = 0.25 g
The concentration of the medication, C = 125 mg/(5 mL)
[tex]V = \mathbf{\dfrac{m}{C}}[/tex]
Therefore;
The volume of the concentration required, V, is given as follows;
[tex]V = \dfrac{0.25 \, g}{125 \times 10^{-3} \ \dfrac{mg}{5 \ mL} } = 10 \, mL[/tex]
The volume of 1 tsps = 4.92892 mL
10 mL = 1 tsps/(4.92892 mL) × 10 mL ≈ 2.03 tsps
Rounding to the nearest whole number gives;
The number of tsps to be given for each dose is approximately 2 tsps
3. The quantity the physician ordered every 4 hours = 650 mg
The quantity of the medication per tablet = 325 mg/tablet
Maximum mass the patient can take in 12 hour = 650mg × 12/4 = 1,950 mg
The maximum number of tablets the patient can receive = 1,950 mg/(325 mg/tablet) = 6 tablets
4. The mass of amoxicillin to be taken every 8 hours = 0.1 g
The concentration of the oral suspension of the drug = 250 mg/(5 mL)
The volume the patient will receive per 24 hour = (24/8)× (0.1 g/(250 mg/(5 mL)) = 6 mL
The amount in mL the patient will receive in 24 hours = 6 mL
5. The mass of Kanamycin to be taken every 6 hours = 1 g
The number of days the of medication = 4 days
The quantity of Kanamycin per capsule = 500 mg
The mass of Kanamycin required for 4 days = ((24 × 4)/6) × 1 g = 16 g
The number of capsules = (16 g)/(500 mg/capsule) = 32 capsules
The number of capsules the client will receive = 32 capsules
6. The volume of Lactated Ringer to be given in 12 hours = 3 Liters
The tubing drop factor = 15 gtt/mL = 15 drops/mL
The number of hours the IV has been running = 9 hours
The volume of IV remaining = 1,500 mL
The number of drops remaining = 1,500 mL × (15 gtt/mL) = 22,500 drops
The time remaining = 12 hour - 9 hour = 3 hours
3 hours = 3 hour × 60 minutes/hour = 180 minutes
The number of drops per minute needed is therefore;
Drops per minute needed = 22,500 drops/(180 minutes) = 125 drops/minute
7. The Penicillin required = 350,000 μ
The available Penicillin = 400,000 μ/(5 mL)
The volume of Penicillin per dose = 350,000 μ/(400,000 μ/(5 mL)) = 4.375 mL
