4, because 4 to the power of two means you multiply that number by itself so 4x4=16. And 16-16=0 <span />

Step-by-step explanation:

Given

f(x) = 4 $(3)^{x}$ , then

f(0) = 4 $(3)^{0}$ = 4 × 1 = 4 [ $a^{0}$ = 1 ]

Answer:

The table is attached!

Step-by-step explanation:

6 students play both musical instrument and a sport
3 students play neither a musical instrument nor a sport
14 students in total play a sport

Given: There are 24 students in the class

The number of students that does not play a sport is 24 - 14 = 10

The number of students that does not play a musical instrument but play a sport = 14 - 6 = 8

The number of printers sold since 2003 at Mike’s office supply store can be modeled by the function N(t) = 15t + 85 and the pric

fiasKO [112]

Answer:

The total amount of revenue is $82950

Step-by-step explanation:

* Lets explain how to solve the problem

- The number of printers sold since 2003 at Mike’s office supply store

can be modeled by the function N(t) = 15t + 85

∴ The number of printers is N(t) = 15t + 85

- The price per printer can be modeled by P(t) = 15t² - 32t + 126

∴ The price per printer is P(t) = 15t² - 32t + 126

- t is the number of years since 2003

- The amount of revenue is the product of the number of printers

sold and the price per printer

∴ Revenue = N(t) × P(t)

- We need to find the total amount of revenue generated by the

sales of printers in the office supply store in 2009

∵ t is the number of years since 2003

∴ In 2009 t = 2009 - 2003 = 6 years

∵ t = 6 years

∵ N(t) = 15t + 85

∴ N(6) = 15(6) + 85 = 175

∴ They sold 175 printers from 2003 to 2009

∵ t = 6 years

∵ P(t) = 15t² - 32t + 126

∴ P(6) = 15(6)² - 32(6) + 126 = 474

∴ The price per printer is $474

∵ Revenue = N(t) × P(t)

∴ Revenue = 175 × 474 = 82950

* The total amount of revenue is $82950
