Vertex of x^2 = (0,0)

Vertex of x^2 - 8x + 7

   Find the roots by factoring
   (x - 7)( x -1 )=0
   x= 7, x = 1
   middle: [7+1]/2 = 8/2 = 4
   g(4) = 4^2 -8(4) + 7 = 16 - 32 + 7 = -9
   Vertex = (4,-9)

Then the translation is right 4, down 9. This is the first option.

The vertex form of the function:
g ( x ) = x² - 8 x + 7 = ( x² - 8 x + 16 ) - 16 + 7 =
= ( x - 4 )² - 9
Answer:
C ) right 4, down 9.

ycow [4]

First round 15.25 to 15.30 and round 4.85 to 4.90 and then add you get 21.20 no it is not reasonable and you round to the decimal ones

If a x 10^n is scientific notation, then a must be between 1 and

Yanka [14]

Answer:

A) 10

Step-by-step explanation:

In the US, a number in scientific notation will have a mantissa (a) such that ...

1 ≤ a < 10

That is, the value of "a" must be between 1 and 10 (not including 10).

_____

Comment on alternatives

In other places or in particular applications (some computer programming languages), the standard form of the number may be a×10^n with ...

0.1 ≤ a < 1

In engineering use, the form of the number is often chosen so that "n" is a multiple of 3, and "a" is in the range ...

1 ≤ a < 1000

This makes it easier to identify and use the appropriate standard SI prefix: nano-, micro-, milli-, kilo-, mega-, giga-, and so on.

(15.2*0.25-48.51/14.7)/x=(13/44-2/11-5/66/2.50)1.2/(3.2+0.8(5.5-3.25)

goldfiish [28.3K]

Answer:

x = 41.67

Step-by-step explanation:

The above equation, would be simplified or divided into parts;

Therefore, the given equation becomes;

A/x = B/C

Where;

A = (15.2*0.25-48.51/14.7)

B = (13/44-2/11-5/66/2.50)1.2

C = 3.2+0.8(5.5-3.25)

x = unknown variable.

Part A

(15.2*0.25-48.51/14.7) = (15.2*0.25 - 3.3)

A = (3.8 - 3.3)

A = 0.5

Part B

(13/44-2/11-5/66/2.50)1.2 = (0.3 - 0.18 - 0.030) * 1.2

B = 0.09 * 1.2

B = 0.108

Part C

(3.2+0.8(5.5-3.25)

C = 4*(2.25)

C = 9

Substituting the values into the equation, we have;

0.5/x = 0.108/9

Cross-multiplying, we have;

9 * 0.5 = 0.108x

4.5 = 0.108x

x = 4.5/0.108

x = 41.67
