a. 1 : 40000 = x : 500000

x = 12.5 cm

b.1 : 40000 = 2 : x

How to find vertex form
Nikolay [14]
Y = x^2 - 6x + 7
a = 1
b = -6
c = 7

Before you get the A.O.S, you must first solve for the vertex.
The vertex formula is \frac{-b}{2a} 

Plug in the numbers:
-(-6) / 2(1)
--6 = 6 and 2*1 = 2
6/2
Vertex (or x) = 3

Now you have to plug in the x in order to find the vertex (or y)
Your equation should now look like this;
y = (3)^2 - 6 (3) +7
Solve each part separately and then add it up...

3^2 = 9
-6 * 3 = -18
+7

9 - 18 + 7
A.O.S (or y) = -2

Find the length of segment x. If necessary, round your answer to the nearest tenth (1 decimal place).
sineoko [7]

The length of the segment x is 16.2

Step-by-step explanation:

Here apply the Pythagorean relationship which states that the sum of squares of the sides is equal to the square of the hypotenuse.

Mathematically,

a²+b²=c²

where a=15, b=6, c=r

Hence;

15²+6²=c²

225+36=c²

√261=c

16.16

x⇒16.2
