Answer:

Step-by-step explanation:

f(0) = -2

f(1) = 3*(f(1 - 1)) - 2*1

f(1) = 3(-2) - 2

f(1) = - 6 - 2

f(1) = - 8

f(2) = 3*(f(1)) - 2*2

f(2) = 3*(-8) - 4

f(2) = -24 - 4

f(2) = - 28

f(3) = 3*(f(2)) - 2*3

f(3) = 3*-28 - 6

f(3) = -84-6

f(3) = - 90

f(4) = 3*f(3) - 2 * 4

f(4) = 3*-90 - 8

f(4) = -270 - 8

f(4) = -278

As a freshman, suppose you had to take two of four lab science courses, one of two literature courses, two of three math courses

Sergeeva-Olga [200]

Answer:

We have 252 different schedules.

Step-by-step explanation:

We know that as a freshman, suppose you had to take two of four lab science courses, one of two literature courses, two of three math courses, and one of seven physical education courses.

So from 4 lab science courses we choose 2:

$C_2^4=\frac{4!}{2!(4-2)!}=6$

So from 2 literature courses we choose 1:

$C_1^2=\frac{2!}{1!(2-1)!}=2$

So from 3 math courses we choose 2:

$C_2^3=\frac{3!}{2!(3-2)!}=3\\$

So from 7 physical education courses we choose 1:

$C_1^7=\frac{7!}{1!(7-1)!}=7$

We get: 6 · 2 · 3 · 7 = 252

We have 252 different schedules.
