Answer:
14.35 grams
Step-by-step explanation:
Amount left, in grams = (970 grams)(1.000 - 0.277)^m, where m is the number of minutes. This is exponential decay.
Amout left = (970 grams)(0.723)^13 = (970 grams)(0.01475), or 14.35 grams
<span>Simplifying
4n + -19 = 13
Reorder the terms:
-19 + 4n = 13
Solving
-19 + 4n = 13
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '19' to each side of the equation.
-19 + 19 + 4n = 13 + 19
Combine like terms: -19 + 19 = 0
0 + 4n = 13 + 19
4n = 13 + 19
Combine like terms: 13 + 19 = 32
4n = 32
Divide each side by '4'.
n = 8
Simplifying
n = 8</span>

![x=-1.433](https://tex.z-dn.net/?f=x%3D-1.433)
<h2>Explanation:</h2>
The easier way to solve this problem is to graph the function using graphing calculator. Here we have the following function:
![y=f(x)= x^3 - x^2 + 5](https://tex.z-dn.net/?f=y%3Df%28x%29%3D%20x%5E3%20-%20x%5E2%20%2B%205)
So this is a cubic function that extends to
as x tends to
and
as x tends to
. This is so because the leading coefficient (the coefficient that accompanies
) is positive. Then, this graph will pass through a point in the x-axis which is the value of the only real solution. The graph shows that this value is:
![x=-1.433](https://tex.z-dn.net/?f=x%3D-1.433)
6.48 divide by 6 and u will get the answer
