A young couple purchases their first new home in 2002 for $120,000. They sell it to move into bigger home in 2007 for $150,000.

Fed [463]

Answer:

The exponential model for the value of the home is $V(t)=120000e^{0.045t}$ .

Step-by-step explanation:

According to the give information 2002 is the initial year and the value of the hom in 2002 is $120,000.

The model will have the form

$V(t)=V_0e^{kt}$

Where V₀ is initial value of home, k is a constant and t is number f years after 2002.

$V(t)=120000e^{kt}$

The value of home in 2007 is $150,000. Difference between 2007 and 2002 is 5 years. Therefore the value of function is 150000 at t=5.

$150000=120000e^{k(5)}$

$\frac{150000}{120000}=e^{5k}$

$\frac{5}{4}=e^{5k}$

Take ln both sides.

$ln(\frac{5}{4})=lne^{5k}$

$ln(\frac{5}{4})=5k$ ( $lne^a=a$ )

$\frac{ln(\frac{5}{4})}{5}=k$

$k=0.04462871\approx 0.045$

Therefore exponential model for the value of the home is $V(t)=120000e^{0.045t}$ .

Where t is number of years after 2002.

What is the decibel level of the sound of a ticking clock with intensity 10−9 watts per square inch? Use a logarithmic model to

In-s [12.5K]

Answer:

β = (-0.19 dB).

Step-by-step explanation:

The formula which is used to calculate the decibel level of a sound is given by :

$\beta=10\log (\dfrac{I}{I_o})$

I is intensity of the sound of a ticking clock

$I_o=10^{-12}\$ watts per square meter

Since, $1\ \text{inch}^2=\dfrac{1}{1550}\ \text{m}^2$

The intensity of a monster truck is converted into per square meter as follows:

$10^{-9}\ {W/in^2}= \dfrac{10^{-9}}{1550}\ W/m^2\\\\10^{-9}\ {W/in^2}=6.45\times 10^{-13}\ W/m^2$

So, Decibal level is :

$\beta=10\log (\dfrac{6.45\times 10^{-13}}{10^{-12}})\\\\\beta =-0.19\ dB$

So, the decibel level of the sound of a ticking clock is (-0.19 dB).

Which of the following explains how ΔAEI could be proven similar to ΔDEH using the AA similarity postulate?

umka2103 [35]

Answer:

∠AEI ≅ ∠DEH because vertical angles are congruent; rotate ΔHED 180° around point E, then translate point D to point A to confirm ∠IAE ≅ ∠HDE.

Step-by-step explanation:

tbh im not suuper sure but my educated guess is that by looking at it. Good Luck!
