Hope this helps. :D
Answer:
a1 =2/5
an = an-1 *5
Step-by-step explanation:
The first term is found when n=1
a1 = 2/5* 5^(1-1)
a1 = 2/5*5^0
= 2/5*1
=2/5
The recursive rule is based on the previous term
We are multiplying each term by 5.
a2 = a1 *5
a3 = a2*5
an = an-1 *5
The method of completing the square can be used to determine the vertex of a function. he unknown value is -162
<h3>Completing the square of a function</h3>
The method of completing the square can be used to determine the vertex of a function.
Given the quadratic function
-2x² + 36x
-2(x²-18)
Complete the square
-2(x² - 18x + ( -9)²+ 9²)
-2(x-9)² + -2(81)
-2(x-9)² - 162
Compare
On comparing with the expression, you can see that the unknown value is -162
