Answer:
Chose forth and fifth answer
If one square takes 16.4 cm of wire, this means that to form 25 identical squares you need 25(16.4) cm of wire = 410 cm
To convert this to m you just need to divide it by 100 because there are 100 cm in one meter = 4.1 m
Therefore your final answer is: You need 4.1 m of wire to form 25 squares, each with a perimeter of 16.4 cm.
The coefficient of the squared expression is 1/9
<h3>How to determine the coefficient of the squared expression?</h3>
A parabola is represented as:
y = a(x - h)^2 + k
Where:
Vertex = (h,k)
From the question, we have:
(h,k) = (-2,-3)
(x,y) = (-5,-2)
So, the equation becomes
-2 = a(-5 + 2)^2 - 3
Add 3 to both sides
1 = a(-5 + 2)^2
Evaluate the sum
1 = a(-3)^2
This gives
1 = 9a
Divide both sides by 9
a = 1/9
Hence, the coefficient of the squared expression is 1/9
