What is the explicit equation for f(0)=8; f(×)=f(×-1)*3

Mathematics

Hello from MrBillDoesMath!

Answer:

f(x) = 8 * 3^x

Discussion:

x = 0: f(x) = 8

x = 1: f(1) = f(0) * 3 = 8*3

x = 2: f(2) = f(2-1)*3 = f(1) * 3 = (8*3)*3 = 8 * 3^2

x=3 : f(3) = f(3-1)*3 = f(2)*3 = (8 * 3^2) * 3 = 8 * 3^3

Based on this we guess that

f(x) = 8 * 3^x

Thank you,

MrB

Use properties of operations to determine whether 4r + 4t and 4(r+t) are equivalent. Explain your answer.

Vikki [24]

There is only one property used to determine whether

$4r+4t=4(r+t)$ .

The property is called the distributive property and in a nutshell it states, $a(b+c)=ab+ac$ , which means $a$ is distributed through $b+c$ using multiplication. So $4(r+t)$ says, distribute $4$ to $r$ and $t$ which then translates into $4r+4t$ .

A triangle with sides of lengths 16,30,and 35 is a right triangle? a. true b. false

Anon25 [30]

-- The square of the shortest side . . . 16² = 256
-- The square of the medium side . . . 30² = 900
-- Their sum . . . (256 + 900) = 1,156

-- The square of the longest side = 35² = 1,225

1,156 and 1,225 are not equal, so these 3 numbers
can be the sides of a triangle, but it's not a right one.

The statement is false. (choice 'b')
