Jesslyn hypothesizes that the value of antique furniture can be modeled by exponential decay and that the value of a particular

piece will decrease at a rate of 0.15% each year. If the furniture was originally valued at $15,000 in 1990 what should Jesslyn expect the value of the furniture to be in 2010?

If this can be modelled by exponential decay, therefore the function must be in the form of:

A = Ao (1 + r)^t

where A is the final value, Ao is the initial = 15000, r is the rate of decay = -0.0015, t is time = 2010 – 1990 = 20

 

A = 15,000 (1 – 0.0015)^20

A = $14,556.36

What are the two things that happen to water molecules when heat energy is added to air?
yuradex [85]

Answer:

When the heat is raised (for instance, as water is boiled), the higher kinetic energy of the water molecules causes the hydrogen bonds to break completely and allows water molecules to escape into the air as gas. We observe this gas as water vapor or steam.

rewona [7]

Answer:

2nd option.

Step-by-step explanation:

3(8 - 4x) < 6(x - 5)

24 - 12x < 6x - 30

Part a)

MAD = median of absolute deviations

MAD = median of the set formed by : |each value - Median|

Then, first you have to find the median of the original set

The original set is (<span>38, 43, 45, 50, 51, 56, 67)


The median is the value of the middle (when the set is sorte). This is 50.


Now calculate the absolute deviation of each data from the median of the data.

1) |38 - 50| = 12
2) |43 - 50| = 7
3) |45 - 50| = 5
4) |50 - 50| = 0
5) |51 - 50| = 1
6) |56 - 50| = 6
7) |67 - 50| = 17

Now arrange the asolute deviations in order

(0, 1, 5, 6, 7, 12, 17)

The median is the value of the middle: 6.

Then the MAD is 6.

Part b) MAD represents the median of the of the absolute deviations from the median of the data.
