If the cube has a side length of 12 inches, what is the surface area of the cube?

Mathematics

The equation for surface area on a cube is 6 * L^2, where L is side length. Essentially, six squares of equal size
12^2=144
6 * 144=864
I hope you found this both helpful and explanatory

The value of a certain car, in dollars, x years from its model year can be predicted by the function f(x)=12,000(0.89)x . The va
scZoUnD [109]
An exponential decay function is:

f=ir^t, f=final amount, i=initial amount, r=common ratio, t=number of times ratio is applied...We can see the initial value is 17000 so all we really have to find is the common ratio, or "rate" as some call it :P  If we look at the second point, when t=1 we can see:

14280=17000r

r=357/425

r=0.84

So in five years the SUV will be worth more than the car by:

17000(0.84^5)-12000(0.89^5)

$408.73  (to the nearest cent)

Point (0, 3)

<u>Step 2: Find slope </u><em><u>m</u></em>

Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>

  1. Substitute in points [Slope Formula]:                                                            \displaystyle m=\frac{3-1}{0-3}
  2. [Fraction] Subtract:                                                                                         \displaystyle m=\frac{2}{-3}
