The Numerical expansion for the phrase is Negaquinary and Balanced Septenary added to Balanced Quaternary.

Simplification Answer : 6(Senary)

Step-by-step explanation:

  • The Numerical expression for the -5 is Negaquinary.
  • The Numerical expression for the +7 is Balanced Septenary.
  • The Numerical expression for the +4 is Balanced Quaternary.
  • STEP 1 : -5+7 = +5
  • STEP 2 : +5+4 = 6.
  • The Numerical expression for the 6 is Senary.

What are the coordinates of the vertex for the function shown below ?
Anuta_ua [19.1K]

Answer:

Step-by-step explanation:

We can answer this in two ways:  Differentiation and Graphing.

<u>Differentitate:</u>

The first derivative of a function yields a function that provides the slope for any point on the line of the original function.  The slope of a vertex is zero, so we can set the first derivative to 0 and solve for x.

f(x) = 3(x-1)^2 + 4

f(x) = 3(x-1)(x-1) + 4

f(x) = 3(x^2 - 2x + 1) + 4

f(x) = 3x^2 - 6x + 7

f'(x) = 6x -6

Set this = 0 and find x:

0 = 6x -6

x = 1

The value of y when x=1 in the original equation is:

f(1) = 3(1-1)^2 + 4

y = 4

The vertex is (1,4)

<u>Graph:</u>

You can use DESMOS to plot the function.  The result is attached.  Look for the vertex and read the coordinates.  (1,4) seems to work.

What is the degree of an angle in a regular heptagon
Ronch [10]
There is 360 degrees in a full revolution.
There are 7 sides/edges/vertices in a heptagon.
360/7 = 51.42857143
The degree of an angle in a regular heptagon is thus 51.42857143 degrees.

SVEN [57.7K]

Answer:

x = 30

Step-by-step explanation:

The sum of the 3 interior angles of a triangle = 180°, hence

x + x + 10 + 3x + 20 = 180

5x + 30 = 180 ( subtract 30 from both sides )

5x = 150 ( divide both sides by 5 )

x = 30
