Answer:
a) The model for the sales of Garmin is represented by 
.
b) The average sales of Garmin from 2008 through 2013 were $ 2.5 billion.
Step-by-step explanation:
a) The model for the sales of Garmin is obtained by integration:
(1)
Where 
is the integration constant.
If we know that 
and 
, then the model for the sales of Garmin is:
The model for the sales of Garmin is represented by .
b) The average sales of the Garmin from 2008 through 2013 (
) is determined by the integral form of the definition of average, this is:

The average sales of Garmin from 2008 through 2013 were $ 2.5 billion.
Answer: the answer is the first one ,the third one , and the fourth
Step-by-step explanation:5x5 25
15x15 225
2/3x+3=6
2/3x=3
x= 3*3/2
x=9/2=4.5

Answer:
Step-by-step explanation:
y = -3(x-3)^2 + 4
Given that, a sphere has a surface area of about 999 square millimeters.
Formula to find the surface area of sphere is,
S= 4πr² Where r = radius of the sphere and S= surface area.
Given S= 999 square millimeters.
So, we can write:
4πr² = 999
4 * 3.14 * r² = 999 Since, π = 3.14
12.56 *r² = 999
Divide each sides by 12.56.
r² = 79.53821656
r = √79.53821656 Taking square root to each sides of equation.
r = 8.918420071
So, r = 8.918 Rounded to nearest thousandth.
So, radius of the sphere is 8.918 millimeters.
Hope this helps you!
