Answer:

this \: paper \: needs \: to \: be \: folded \:  \\  \underline{ \boxed{twice \: (2 \: times)}}

Step-by-step explanation:

let \: the \: let \: the \: length \: be \to \: x \\when \: folded :  it \: becomes \to \:  \frac{x}{2}  \\hence : \to \\  93.5 \times  \frac{x}{2}  = (93.5 - 1) \\ 93.5x = 2(93.5 - 1) \\ 93.5x = 2 \times 92.5 \\ 93.5x = 185 \\ x =  \frac{185}{93.5}  \\  \boxed{x = 1.9786096257 }\\

What is the volume of the sphere?
Ilia_Sergeevich [38]

Answer:

V = 4/3 pi or approximately 4.187 ft^3

Step-by-step explanation:

The volume of a sphere is given by

V = 4/3 pi r^3

The radius is 1 ft

V = 4/3 pi (1)^3

V = 4/3 pi

We can approximate pi by 3.14

V = 4/3 (3.14)

V = 4.186666666 ft^3

Answer:

1. -8x² - 16x - 6      a = -8, b = -16, c = -6

1. 4x² - 1                  a = 4, b = 0, c = -1

Step-by-step explanation:

use the 'foil' method:

(4x + 2)(-2x - 3)

F: -8x²     O: -12x       I: -4x       L: -6

-8x² - 16x - 6

(2x + 1)(2x - 1)

F: 4x²     O: -2x       I: 2x       L: -1

4x² - 1

Andrea Is selling candles as a fundraiser she spent $50 on supplies for making the candles she plans to sell candles for $10 eac
dalvyx [7]

COMPLETE QUESTION:

Andrea is selling candles as a fundraiser. She spent $50 on supplies for making the candles. She plans to sell the candles for $10 each. Her profit can be modeled by C(x) = 10x - 50.

What type of function is this?

What is the domain and range of the function?

Answer:

- This function is one-to-one

- Domain D = {x: x is a whole number ≤ Z}

- Range R = {y: y is in -50, ..., (10Z - 50)}

Where Z is the number of candles she could produce with $50.

Step-by-step explanation:

Given that her profit is modeled by C(x) = 10x - 50

- This function is one-to-one, because it is in the form f(x) = y.

Let the number of candles she could make with $50 be Z.

Then the domain is the set of all whole numbers less or equal to Z.

D = {x: x is a whole number ≤ Z}

If there are infinite number of candles she could make with that money, then

D = (-infinity, infinity)

When x = 0, we have C = -50

When x = Z, we have C = 10Z - 50

The range is then given as

R = whole numbers from -50 up to (10Z - 50)

R = {y: y is in (50 -Z), ..., (10Z - 50)}

If there are infinite number of candles she could make with that money, then

R = (-infinity, infinity)
