The number of camera phones shipped globally can be modeled by the function y=1.28e^1.31x where x is the number of years since 1
erik [133]
The first thing you should know for this case is how many years there are from 1997 to 2014.
 The number of years is:
 x = 2014-1997 = 17
 Then, you must replace this value in the given equation:
 y = 1.28e ^ 1.31x
 y = 1.28 * e ^ (1.31 * (17))
 y = 6011018736
 answer:
 the number of camera phones shipped in millions in 2014 is
 y = 6011018736

A circular flower bed is 24 m in diameter and has a circular sidewalk around it that is 2 m wide. Find the area of the sidewalk
Doss [256]
The area of the sidewalk is 144.44 m².

The 2-m wide walk adds 4 m to the diameter, making it 21+4=25.

Since the radius is half the diameter, r = 25/2 = 12.5.

The area of the entire bed with walkway is 3.14(12.5)² = 490.625 m².

The diameter of the bed is 21, so the radius is 21/2 = 10.5.
The area of just the flower bed is 3.14(10.5)² = 346.185.

The difference between the two is 490.625-346.185 = 144.44 m². This is the area of the walkway.

Solve the following inequality: 10t + 7 , 200 > 21 , 000
Alla [95]

Answer:

t > 1380

Step-by-step explanation:

Subtract 7200 from both sides

10t + 7200 - 7200 > 21000 - 7200

Simplify

10t > 13800

Divide both sides by 10

10t/10 > 13800/10

Simplify

t > 1380
