F(n) = 2• (-3)^n

Mashutka [201]

Answer:

$f(1)=-6$

$f(n)=f(n-1)(-3)$

Step-by-step explanation:

We are given that

$f(n)=2\cdot (-3)^n$

We have to complete the recursive formula of f(n).

Substitute n=1

$f(1)=2\cdot (-3)$

$f(1)=-6$

$f(2)=2\cdot (-3)^2=18$

$f(3)=2\cdot (-3)^3=-54$

$\frac{f(2)}{f(1)}=\frac{18}{-6}=-3$

$\frac{f(3)}{f(2)}=\frac{-54}{18}=-3$

It forms geometric sequence because the ratio of two consecutive terms are equal.

Therefore, the recursive formula

$f(n)=f(n-1)r$

$f(n)=f(n-1)(-3)$

The lines graphed below are perpendicular. The slope of the red line is -2. What is the slope of the green line?

timurjin [86]

The slope of the green line would be 1/2

Perpendicular lines have opposite and reciprocal slopes. This means we first have to take the -2 and make it opposite to its current sign (2). Now we can take the 2 and flip it as a fraction (1/2).

This gives us the slope
