Answer:
13.2 years
Step-by-step explanation:
The decay rate is 15%, so the decay factor is 1 - 15% = 0.85. Then the exponential equation for the value is ...
v(t) = 85000·0.85^t
We can set v(t) = 10,000 and solve for t:
10000 = 85000·0.85^t
10000/85000 = 0.85^t . . . . divide by 85000
log(2/17) = t·log(0.85) . . . . . .reduce fraction, take logs
t = log(2/17)/log(0.85) ≈ 13.2
It will take about 13.2 years for the value to fall below $10,000.

Such a question is nicely answered by a graphing calculator.
Volume of solid created = .
<u>Step-by-step explanation:</u>
We have , A new solid is created by cutting a right rectangular prism from a cube. The right rectangular prism has a length of 5 m, a width of 4 m, and a height of 2 m. The side lengths of the cube are 5 m . Volume of solid created = Volume of cube - Volume of rectangular prism
Volume of cube =
⇒
⇒
⇒
Volume of rectangular prism =
⇒
⇒
⇒
Now, Volume of solid created = Volume of cube - Volume of rectangular prism
⇒ Volume of solid created =
⇒ Volume of solid created =
⇒ Volume of solid created =
∴ Volume of solid created = .
