The milligrams of aspirin in a person's body is given by the equation a=500(3/4) ^t, where t is the number of hours since the patient took the medicine. How much aspirin will be in the patient's body after two hours?
Answers
The amount of aspirin that will be present in the patient's body after two hours is 281.25 milligrams.
How to evaluate a given mathematical expression with variables if values of the variables are known?You can simply replace those variables with the value you know of them and then operate on those values to get a final value. This is the result of that expression at those values of the considered variables.
For this case, we have:
Amount of aspirin in a person's body (in milligrams) after t hours of taking the medicine is:
[tex]a = 500\times(\dfrac{3}{4})^t[/tex] (in milligrams)
For t = 2 hours, we get:
[tex]a = 500\times(\dfrac{3}{4})^2 = 281.25 \: \rm milligrams[/tex]
Thus, the amount of aspirin that will be present in the patient's body after two hours is 281.25 milligrams.

what two numbers multiply to -36 and add up to 5
Answers
Answer:
9 and -4
Step-by-step explanation:
Finding these 2 numbers can be found by guessing and checking. By doing this, it will get you the numbers 9 and -4.
First, test if they multiply to -36:
9(-4)
= -36
Then, check if they add up to 5:
9 + (-4)
= 5
So, 9 and -4 are the 2 numbers that multiply to -36 and add to 5

What is the value of f(12)?
Answers
Answer:
116
Step-by-step explanation:
To find f(12), plug in 12 as x in the equation:
f(x) = 2/3x + 9x
f(12) = 2/3(12) + 9(12)
f(12) = 8 + 108
= 116
So, f(12) = 116

help idk how to do math
use the distributive property
Answers
Answer:
Distributive property is when you multiply or add the numbers in the parentheses equally to the number outside the parentheses.
That probably isn't a good answer, here's what I found on google:
To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.
Step-by-step explanation:
I'll do #10 as an example:
(x-5)y
distribute the numbers- y(x)-y(5)
without the parentheses- yx-y5
you can't really get an answer by multiplying a number and a variable, or a variable and a variable, so you just leave them and take the parentheses.
Here's #11:
-4(2a-3b+c)
distribute the numbers- (-4*2a)-(-4*3b)+(-4c)
solve- -4*2= -8
-4*3= -12
-8a-(-12)b+4c
*I dunno how to use parentheses for negative numbers but what I did for distributing is pretty much the same thing
Hope this helps you.
