Papessa [141]2 years ago
5 0

Answer:

20

Step-by-step explanation:

(f + g)(x) = f(x) + g(x)

f(x) + g(x) = 3x² - 2 + 4x + 2 = 3x² + 4x

Substitute x = 2 into f(x) + g(x)

(f + g)(2) = 3(2)² + 4(2) = (3 × 4) + 8 = 12 + 8 = 20

ASHA 777 [7]

Answer:

3003

Step-by-step explanation:

We want to find out how many ways we can choose 10 players among 15 players (since the goalie is not interchangeable)

The number of different lineups you can have can be found by using combination:

^{15}C_{10} = \frac{15!}{(15 - 10)! 10!}\\ \\= \frac{15!}{5! * 10!} \\\\= 3003

There are 3003 different lineups that can be chosen.

SI = PRT /100

1. SI = 400*5*1/100
        = 2000/100
        = $ 20

2. SI = 1000*8.5*3/100
        = 25.5*1000/100
        = $ 255

3.  SI = 200*9*1/2*100
         = 900/100
         = $9

4.  SI = 20000*12*3/100
         = 200*12*3
         = 7200

5.  SI = 1200*4.5*6/12*100
         = 4.5*6
         = $27
  
Amount to pay = Principal + SI
                        = 1200+27
                        = $1227 ( But this answer isn't there in the options )
