Answer:

y = (1.1)x is exponential growth

I'm assuming that y = ()x is 1/4 because that's what I got. y = (1/4)x is Exponential decay.

3, 15, 75, 375, ... is a Geometric Sequence

0, 4, 4, 8, ... is an Arithmetic sequence

2, 9, 16, 23 is a recursive sequence.

Step-by-step explanation:

The first two I honestly just guessed but for recursive sequences, you have to look at each previous set of terms and run the math, whether that is Addition, Subtraction, Multiplication, or Division, whatever equation gets you to the next number in line is your equation, and you keep doing so until you've reached the end of the equation. Ex: 2+7=9, 9+16=23.

The area of a rectangular wall of a barn is 192 sq. Ft. It's length is 8 ft. Longer than twice it's width. Find the length and w
Novay_Z [31]

Answer: length = 24 ft

Width = 8 ft

Step-by-step explanation:

Let L represent the length of the barn.

Let W represent the width of the barn.

The area of a rectangular wall of a barn is 192 sq. Ft. This means that

LW = 192- - - - - - - - - - - - - - -1

It's length is 8 ft longer than twice it's width. This means that

L = 2W + 8

Substituting L = 2W + 8 into equation 1, it becomes

W(2W + 8) = 192

2W² + 8W = 192

2W² + 8W - 192 = 0

Dividing through by 2, it becomes

W² + 4W - 96 = 0

W² + 12W - 8W - 96 = 0

W(W + 12) - 8(W + 12) = 0

(W - 8)(W + 12) = 0

W = 8 or W = - 12

Since the width cannot be negative, then W = 8

L = 192/W = 192/8

L = 24
