NEED HELP ASAP: WILL MARK BRAINLIEST: The graph of a function g is shown below.
Use the graph of the function to find its average rate of change from x=-1 to x=3.
Simplify your answer as much as possible.
Step-by-step explanation:
the change rate is expressed by y/x (like the slope of a line).
for x = -1 we get y = -3
for x = 3 we get y = 5
so, while x is changing by 4 units (-1 to +3), y changes by 8 units (-3 to +5).
the average charge rate is therefore

Find the nth term for the following sequences, 100,96,90,82,72.(an^2+bn+c)
9514 1404 393
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

Additional comment
As you might guess, there is a generic solution for quadratic sequences. In terms of the first term (a1), first first difference (d1), and second difference (d2), the coefficients can be written as ...
a = d2/2b = d1 -3ac = a1 -d1 +d2This sequence has first differences of -4, -6, -8, -10, and second differences of -2. Putting the sequence values into the above formulas, we find ...
a = -2/2 = -1b = -4 -3(-1) = -1c = 100 -(-4) +(-2) = 102 . . . . . as abovePLEASE HELP WILL GIVE BRAINLIESTTTT

After a 90% reduction, you purchase a new clothes dryer on sale for $62. What was the original price of the clothes dryer?
Answer:
$7.20
Step-by-step explanation:
First, we would have to find out how much to subtract from $62.
We need to multiply 90% and 62 or 0.9 x 62
When we finish this equation we get 54.8, which is what we need to subtract from 62 to see what 90% off is.
62 - 54.8 = 7.2, so therefore our answer is $7.20

1. The physician has ordered 1000 mL of saline to infuse at 125 mL/hr. How many hours will it take to infuse the fluid?
2. The order is 0.25 g po qid. The medication is available as 125mg /5mL. How many tsps. will be given for each dose?
3. The physician has ordered ASA 650 mg p.o. Q 4 hr. for temperature higher than 101° F. The medication is supplied in 325mg tablets. What is the maximum number of tablets the patient can receive in any 12-hour period?
The physician has ordered amoxicillin 0.1 g p.o. Q8hr. Drug available is amoxicillin oral suspension, 250 mg/5mL. How many mL will the patient receive in 24 hours?
15. ____________ Order: Kanamycin (Kantrex) 1 g po Q6hr x 4 days. Available: Kanamycin capsules, 500 mg. How many capsules will the client receive in the 4 days he is to receive this medication?
16. ____________ Three liters of IV Lactated Ringer' is ordered to be given over 12 hours. The tubing drop factor is 15gtt/mL. The IV has been running for 9 hours. 1500 mL remain. How many drops per minute are needed so that the IV finishes in the required time?
17. ____________ Order: Penicillin, 350,000 U. Available: Penicillin, 400,000 U/5 mL.
How many mL will be administered to the patient per dose?
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

The sum for a 7-sided interior polygon is 900
126+158+120+125+121+139=789
900-789=111
Answer:
x = 111°
Step-by-step explanation:
x + 120+158+126+125+121+139= 900°
x + 789 = 900
x = 900 - 789
x = 111
Deshaun rented a truck for one day. There was a base fee of $18.95, and there was an additional charge of 89 cents for each mile driven.
Deshaun had to pay $171.14 when he returned the truck. For how many miles did he drive the truck?
Step-by-step explanation:
$171.14 in total.
minus the base price
171.14 - 18.95 = 152.19
this we now have to divide by the mile charge, to see how often that fits into the price paid. that will then tell us how many miles were driven.
152.19 / 0.89 = 171 miles were driven.

How could you determine the coordinates of the vertices of a translated image without using a graph?
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).
