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

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

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

An example of a situation in which it is appropriate to use a rational number but not an integer

stepladder [879]

If Jerry, Joe, and David each get 1/3rd of a pizza, how can you express it as an integer?

Trick question - you can't! 1/3rd is 0.3 (with the 3 repeating) which can't be an integer

What is the surface area of this triangular prism? The base of each triangle is 42 m and the height of the triangular base is 20

shutvik [7]

<u>Given</u>:

The base of each triangular base is 42 m.

The height of each triangular base is 20 m.

The sides of the triangle are 29 m each.

The height of the triangular prism is 16 m.

We need to determine the surface area of the triangular prism.

<u>Surface area of the triangular prism:</u>

The surface area of the triangular prism can be determined using the formula,

$SA=bh+(s_1+s_2+s_3)H$

where b is the base of the triangle,

h is the height of the triangle,

s₁, s₂ and s₃ are sides of the triangle and

H is the height of the prism.

Substituting the values, we get;

$SA=(42)(20)+(42+29+29)(16)$

$SA=840+(100)(16)$

$SA=840+1600$

$SA=2440$

Thus, the surface area of the triangular prism is 2440 m²
