From the function y=x^2-4x+7
to complete the square we proceed as follows:
The vertex form is given by:
y=(x-h)^2+k
where (h,k) is the vertex:
thus from the function we shall have:
y=x^2-4x+7
c=(b/2a)²
c=(4/2)²=4
thus adding an subtracting 4 in the expression:
y=x^2-4x+4-4+7
y=(x-2)^2+3
thus the vertex will be:
(2,3)

Answer:
!. Scale factor = 5
2. Scale factor = 
Step-by-step explanation:
scale = 
1. To increase the numbers, let the scale factor be
= 5. So that;
0.05 x 5 = 0.25
x 5 = 0.5 x 5 = 2.50
7 x 5 = 35.00
13 x 5 = 65.00
25 x 5 = 125.00
102 x 5 = 510.00
2. To decrease the numbers, let the scale factor be
. So that;
0.05 x
= 0.01
x
= 0.5 x
= 0.10
7 x
= 1.40
13 x
= 2.60
25 x
= 5.00
102 x
= 20.40
1946 times 3/100=58.38
58.38 times 5 =291.9
1946-291.9=165.41
165.41 is the answer. Please mark brainliest.
1 meter :12 cm
1 cubic meter = 1 x 1 x 1 : 12 x 12 x 12 = 1,728 cubic cm.
A. The smaller the number, the wider the graph. That equation had the smallest number, so therefore it will produce the widest graph.
