You will have earned in $144 in interest.
Answer:
x= 0 , ,
Step-by-step explanation:
Given, equation is + = . →→→ (1)
Now, by cubing the equation on both sides, we get
( + )³ = ()³
⇒ (15x-1) + (13x+1) + 3×× ( + ) = 64 x.
⇒ 28x + 3×× () = 64x.
(since from (1), + = )
⇒ 12× × ()= 36x.
⇒ 3x = .
Now, once again cubing on both sides, we get
(3x)³ = ()³.
⇒ 27x³ = (15x-1)(13x+1)(x).
⇒ 27x³ = 195x³ + 2x² - x
⇒ 168x³ + 2x² - x = 0
⇒ x(168x² + 2x -1) = 0
⇒ by, solving the equation we get ,
x = 0 ; x = ; x =
therefore, solution is x= 0 , ,

Considering the volume of the cylinder, it is found that Cai has collected 327.9 grams of trace element.
<h3>What is the volume of a cylinder?</h3>
The volume of a cylinder of radius r and height h is given by:
.
In this problem, we have that the radius and the height are given, respectively, by:
r = 9.3 cm, h = 17 cm.
Hence the volume of the cylinder in cubic centimeters is given by:
A water sample shows 0.071 grams of some trace element for every cubic centimeter of water, hence the amount of trace element is given by:
0.071 x 4619 = 327.9 grams.
