The <em><u>correct answer</u></em> is:
Explanation:
An exponential function is of the form
, where a is the initial population, b is 1 plus the amount of yearly change, and x is the number of years.
For our problem, a, the initial population, is 1500.
The yearly change is 6.3%; 6.3% = 6.3/100 = 0.063. Since it is decreasing, this is negative; 1+(-0.063) = 0.937.
We use t as the number of years.
This gives us
Answer:
Third step is incorrect. The correct factored form is (x-1)(2x-5).
Step-by-step explanation:
The given expression is
We need to find the factored form of this expression.
Step 1: Given
Step 2: Splitting the middle term method, the middle term can be written as (-5x-2x).
Step 3: Taking out common factors from each parenthesis.
Step 4: Taking out common factors.
Therefore, the third step is incorrect. The correct factored form is (x-1)(2x-5).
