8-21
9- -16 i think lemme do the next ones
By the order of operations, it can be written as
(6*7)-(3^2)*9+(4^3)
Then do it
42-9*9+64=25
Answer:
- <u>200,000</u><em> 6-digit numbers can be constructed.</em>
Explanation:
Since the number is greater than 600,000, the first digit must be 6, 7, 8, or 9, so 4 different options: 4
The second, third, fourth, and fith digits can be either number 0 through 9, so 10 options for each one: 10 × 10 × 10 × 10.
Since the number must be odd and greater than 600,00, the last digit is odd, so it can be 1, 3, 5, 7, or 9, so 5 different options: 5.
Using the multiplication counting principle, you muliply the independent options to obtain the number of different combinations:
- 4 × 10 × 10 × 10 × 10 × 5 = 200,000.
Simplified form of an expression 7/9/2/3 is 7/6.
By considering given expression
7/9/2/3= 7/9 x3/2=7/6
Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows: Expression: (Math Operator, Number/Variable, Math Operator)
An expression or mathematical expression in mathematics is a finite combination of symbols that is well-formed in accordance with context-dependent rules.

Answer:
Step-by-step explanation:
Given
Initial population was people
By 2020, it becomes people
Suppose the population follows the trend
where, is the number of years after 2014
For year 2020 it is 6. Insert the values
Thus, the exponential population trend is
