Mathematics
1 answer:
Anna007 [38]4 years ago

Answer:

t=8

Step-by-step explanation:

Subtract 12t from both sides

(12t-12t) + 16 = (13t-12t) + 24

16 = 1t (or just t) + 24

Then subtract 16 from both sides, and bring "t" over the equals sign making it a negative integer.

-t = 8

t = 8

Is the first one correct and what are the ages?
liraira [26]
For the first question (10a) I think 4x - 4 = 64 could also model the situation. For the ages, Ari is 17, Bill is 34, and Chris is 13. To check, we add them up and get a total of 64. Hope this helps.

131. A patient in a hospital needs to maintain a certain amount of a medication in her bloodstream to fight an infection. Suppos
Nikitich [7]

Answer:

Y=3n+10

Step-by-step explanation:

Hello,

The first thing we should know is that this exercise is modeled by equating a straight line, which is Y = mx + b

where Y, is the value in milligrams of the patient's dose, b is the intercept with the Y axis and x is the number of hours that pass, and m is the slope, taking into account the above we infer the following equation

Y=mn+b

Now what we do is find every 2 points of the line using the problem data, in order to find the complete equation and the slope,

N1=0   Y1=10mg

N2=1     Y2=10mg+4mg=14mg

b is the value of Y when n = 0 therefore b = 10

Now we remember the equation of the slope

m=\frac{Y2-Y1}{N2-N1} =\frac{14-10}{1-0} =4mg/hour

the ecuation is

Y=4n+10

Finally, the problem explains that the body loses 25% of the medication, therefore we multiply the equation by the 75% that remains in the body taking into account that the initial dose for N = 0 must be 10mg.

Y=0.75(4n+\frac{10}{0.75} )=3n+10\\\\

final ecuation

Y=3n+10

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!
Leviafan [203]

Answer:  \bold{(A)\ a_n=500,000(1.1)^{n-1}}

<u>Step-by-step explanation:</u>

From the data provided, we know the sequence is {500,000; 550,000; 605,000; ... }.  So, a_1 = 500,000\ and\ r = \dfrac{550,000}{500,000}=1.1

The explicit rule for a geometric sequence is: a_n=a_1(r)^{n-1}

So, the explicit rule for the sequence above is: a_n=500,000(1.1)^{n-1}
