If f(1) = 1 and f(n) = f(n-1)2 – 4 then find the value of f(4).

Pie

F(1) = 2

f(2) = -5f(2-1) = -5f(1) = -5(2) = -10

f(3) = -5f(3-1) = -5f(2) = -5(-10) = 50

So, f(4) = ?

The surface area A of a cube is equal to the sum on the areas of the 6 square faces that form the cube. If each face has side le

algol [13]

Answer:

18 units

Step-by-step explanation:

Hello, I can help you with this.

Step 1

identify

we have a equation, let's look it

A=6s2

The surface area A of a cube=6(area of a face)

area of face= side*side

Area=6*side*side

Step 2

isolate side from the equation

$side^{2}=\frac{Area}{6}\\side=+\sqrt{\frac{Area}{6}}$

we are looking for a distance, so , we will use only the positive root

Step 3

replace the value of 1944 square units into the equation

$side=+\sqrt{\frac{Area}{6}}\\side=+\sqrt{\frac{1944}{6}}\\side=\sqrt{324}\\\\side=18\\$

so, the value x of a side of a cube with a total

the side of a cube is 18 units when the surface area of the cube shown is 1944 units2

Have a good day.
