Answer:
The expression that models the growth of users is:
The rate of change per quarter is 7.5%
Step-by-step explanation:
Since the number of users is growing at a rate of 30% per year, then initially we have 5400, but after the first year we will have:
After the second year we will have:
After the third year we will have:
This will continue as the years passes. Therefore:
The rate of change pre quarter of year is the rate of change pre year divided by 4,therefore:
Answer: B. it is a binomial with a degree of 3
<u>Step-by-step explanation:</u>
3xy² + 5x²y
There are two terms so it is a BINOMIAL
xy² has a degree of 1 + 2 = 3
x²y has a degree of 2 + 1 = 3
The largest sum of exponents in a term is three so DEGREE is 3
Answer:
x=−5

Answer:
1. 2268.
2. 12.
Step-by-step explanation:
1. Given the mathematical expression; 2 * 2 * 9 * 7 * 9
We would simplify the expression;
2 * 2 * 9 * 7 * 9 = 4 * 81 * 7
2 * 2 * 9 * 7 * 9 = 28 * 81
2 * 2 * 9 * 7 * 9 = 2268
2. Given the mathematical expression; 2² + 2 * 2²
From BODMAS (Bracket Of Division Multiplication Addition Substraction), we would first of all multiply before performing an addition operation.
Therefore,
2² + 2 * 2² = 4 + 2 * 4
2² + 2 * 2² = 4 + 8
2² + 2 * 2² = 12
