Graphing is good to graph a line. Substitution is good because you have to subtitute the value whichis easy and elimination is good just to find oone variable first and the other variable

Graphing is a good method when you have small integers or fractions as your slope.
Substitution is a good method when you have two equations, and when one of the coefficient of the variables is one.
Linear combinations is a good method when you have the same coefficient for the same variable in 2 different equations.

f(5)=12 for a geometric sequence that is defined recursively by the formula f(n)=0.3*f(n-1), where n is an integer and n>0. F
ElenaW [278]

Answer:

f(7) = 1.08

Step-by-step explanation:

Given that:

f(5) = 12

A geometric sequence that is defined recursively by the formula

f(n) = 0.3 \cdot f(n-1)       .....[1 ] where, n is an integer and n> 0.

Substitute n = 6 in [1] we have;

f(6) = 0.3 \cdot f(5)

Using f(5) = 12 we have;

f(6) = 0.3 \cdot 12

⇒f(6) =3.6

We have to find f(7).

Substitute n = 7 in [1] we have;

f(7) = 0.3 \cdot f(6)

Substitute the given values f(6) = 3.6 we have;

f(7) = 0.3 \cdot 3.6

Simplify:

f(7) = 1.08

Therefore, the value of f(7)to the nearest hundredth is, 1.08
