Answer:

The function y = ⌊x⌋ is called the "greatest integer value" function.

it works as follows: the input is any number x, the output is the greatest

integer smaller or equal to x.

For example:

⌊0.1⌋=0

⌊0.26⌋=0

⌊0.4678⌋=0

⌊0.8989⌋=0

⌊0.999⌋=0

⌊1⌋=0

⌊1.0001⌋=1

so, the value of ⌊x⌋, for the entire interval (0, 1] is 0.

Similarly,

the value of ⌊x⌋, for the entire interval (1, 2] is 1. and so on,

thus the graph of y = ⌊x⌋ is as shown in picture 1

the graph of y = ⌊x⌋ – 2 is the graph of y = ⌊x⌋ shifted 2 units down.

check picture 2.

Part A.) in another baseball game division, one team had a winning percentage of 0.444... what fractions of the game did the tea

sattari [20]

Answer:

4/9

Step-by-step explanation:

0.4444... can be written as a geometric series with first term 0.4 and common ratio 0.1. Each new digit is 0.1 times the previous digit.

0.4

Then 0.4444... = ------------ = 0.4/0.9 = 4/9

1 - 0.1

You may check this result by dividing 4 by 9 on a calculator.

PLEASE SEE ATTACHED IMAGE.
For this case what you should do is find the area of the triangle which will be given by:
A = (1/2) * (b) * (h)
Where
b: base
h: height
Substituting the values we have:
A = (1/2) * (25 1/2) * (15)
A = 191.25 feet ^ 2
Answer:
she will need 191.25 feet ^ 2 to cover the back of the cabin
