Answer:

11. It will take about 26 minutes to install a singular tile.

12. It will take about 10 more minutes to install a light than it does to install a cable.

Step-by-step explanation:

11. Since installing 15 new tiles took a total of 390 minutes and each tile took the same amount of time, you can divide the total amount of time by the number of tiles.

390/15= 26 minutes

It will take about 26 minutes to install a single tile.

12. By looking at the chart it can be assumed that installing a light takes about 22 minutes since it is in the middle of 20 and 24 minutes. Installing a cable only takes 12 minutes.

22-12= 10 minutes

It takes about 10 minutes longer to install a light than it does a cable.

What is the difference between Laplace Transform and fourier Transform?
marta [7]

Real time mapping of a function to a new function is known as Fourier transforms. The new mapped function is defined for an interval of (-∞, ∞).

<span>While the Laplace transform is the counterpart, in which a function is mapped to a new function on complex plane. Functions defined for span t≥0 are used by Laplace transformation. </span>

How deep is a well that takes eight cranks on the six- inch diameter windlass to raise the bucket?
Nookie1986 [14]
In order to answer this, you would need to find the circumference of the windlass. This would represent the distance of one rotation. When you know the distance of one rotation, you would then multiply it by eight for all eight Kranks. This is knowing each crank is a complete turn. Here is the formula C= pi times the diameter. So, 3.14 x 7 is 18.84 inches for 1 crank. 18.84 inches times 8 equals 150.72 inches. This is an approximation because pi is an approximation.

For accounting purposes, the value of assets (land, buildings, equipment) in a business are depreciated at a set rate per year.
zloy xaker [14]
This is exponential decay of the form:

f=ir^t, f=final value, i=initial value, r=rate, t=time in this case:

V(t)=408000((100-18)/100)^t

V(t)=408000(0.82)^t  so

Vo=408000 and b=0.82

....

V(8)=408000(0.82)^8

V(8)=$83400.95  to nearest cent
