Answer:
Step-by-step explanation:
we know that
The formula to calculate the depreciated value is equal to
where
V is the depreciated value
P is the original value
r is the rate of depreciation in decimal
x is Number of Time Periods
in this problem we have

substitute
.85*36,000=30,600
30,600*0.09=2754
30,600-2754=$27,846
Answer:
~ B
Explanation:
~ It’s B because it has a question mark, and a polynomial is an equation that has two or more variables, all the options on top have 2 or more variables
~ A polynomial cannot have a root, fraction of anything else, hence I believe it’s B
Answer:
5.131 × 10¹⁴ Hz
Step-by-step explanation:
<u>Planck relation</u>

where:
- E = Energy of the photon (J).
- h = Planck's constant (J · s).
- f = frequency of light produced (Hz).
Given values:
- E = 3.4 × 10⁻¹⁹ J
- h = 6.626 × 10⁻³⁴ J · s
Substitute the given values into the formula and solve for f:
