Answer:
-89 is rational
√101 is irrational
Step-by-step explanation:
An irrational number is a number that <u>cannot</u> be expressed as a fraction in terms of whole numbers.
-89 = -89/1 which is a fraction and is therefore rational
√101 does cannot be put into a fraction of whole numbers and is therefore irrational
First we define the variable to be used:
x: half-life time period
The equation for this problem can be modeled as:
y = A * (b) ^ x
Where,
A: initial amount
b: decrease rate.
For example:
if there are 100 atoms, after one half-life time period, 50 atoms remain:
y = 100 * (0.50) ^ x
after one half-life time period (x = 1):
y = 100 * (0.50) ^ 1
y = 50
The equation that models the problem is:
y = 16 * (0.50) ^ x
The table is:
1 8
2 4
3 2
4 1
5 0.5
Answer:
That is tough
Step-by-step explanation:
Answer:
it is true. any whole number has a 0 following the decimal
(5)(3)(4(2)-2(3))=
15(8-6)=
15(2)=
30. Hope this helps!
