.Jim opened an account with $400. The account pays three percent quarterly. How much is in the account at the end of two years?

podryga [215]

We may have this planned like this:
two years is 8 quarters
Assuming simple interest, 
You will use the formula
A = P(1+rt) 
= 400(1+8*.03) 
= 496
I think this is the answer:) Hope it helps a lot

A rectangular tank with a square base, an open top, and a volume of 8 comma 7888,788 ft cubedft3 is to be constructed of sheet

Vlad [161]

Answer:

26 ft square by 13 ft high

Step-by-step explanation:

The tank will have minimum surface area when opposite sides have the same total area as the square bottom. That is, their height is half their width. This makes the tank half a cube. Said cube would have a volume of ...

2·(8788 ft^3) = (26 ft)^3

The square bottom of the tank is 26 ft square, and its height is 13 ft.

_____

Solution using derivatives

If x is the side length of the square bottom, the height is 8788/x^2 and the area is ...

x^2 + 4x(8788/x^2) = x^2 +35152/x

The derivative of this is zero when area is minimized:

2x -35152/x^2 = 0

x^3 = 17576 = 26^3 . . . . . multiply by x^2/2, add 17576

x = 26

_____

As the attached graph shows, a graphing calculator can also provide the solution.

Write 0.00000000000801 in scientific notation.

Nana76 [90]

$801 \times {10}^{ - 14} = 8.01 \times {10}^{ - 12}$

Done...

Good luck ♥️♥️♥️♥️♥️.
