The slope of the equation is calculated as:

Where
is the height of the upper part of the slope and
is the height of the low er part.


So, the equation of the line is:


With this equation we can find the height of Alberto after having passed 10 sec.

After 10 seconds Alberto is 350 feet from the bottom of the slope.
Alberto's speed is:

The speed in miles per hour is:

Answer:
Prediction model for Jewelry sales 7.15 billion = 2 billion {1+r%}¹⁰
Jewelry sales in 2015 = 8.343 billion dollars
Step-by-step explanation:
The compound interest expression is used to describe the increase in Jewelry sales
A = P{1+r%}ⁿ = 7.15billion = 2billion {1+r%}¹⁰
Where A= Jewelry sales in 2013
P Jewelry sales in 2010
r= annual rate increase
n= number of years
r is then calculated from 7.15billion = 2billion {1+r%}¹⁰
Therefore 3.575billion = {1+r%}¹⁰
¹⁰√3.575 × 10⁹ = 1+r%
9.022514830966 = 1+r%
r% = 8.022514830966%
Jewelry sales by 2015 = A = P{1+r%}ⁿ where n= 2
A = 7.15×10⁹{1+8.022514830966/100}² = 8.34370097596 × 10⁹
Therefore Jewelry sales in 2015 = 8.343 billion dollars
