For
ax^2+bx+c
the axis of symmetry is -b/2a


first one
-3/2=3, nope

2nd one
3/2=3? nope

3rd one
-6/2=3? nope

fourth
6/2=3? yes
answer is last one or

Answer:

Option 4th is correct

f(x) = x^2-6x-1

Step-by-step explanation:

A quadratic equation is in the form of: y=ax^2+bx+c.....[1]; then the axis of symmetry is given by:

x = \frac{-b}{2a}

As per the statement:

To find :

The graph of which function has an axis of symmetry at x = 3

From the given options:

Option 4th is the graph of a function which has axis of symmetry at x = 3

Consider a function:

f(x) =x^2-6x-1

On comparing with [1] we have;

a = 1  and b = -6

then;

x = \frac{-(-6)}{2 \cdot 1}

⇒x = \frac{6}{2} =3

Therefore, The graph of which function has an axis of symmetry at x = 3 is, f(x) = x^2-6x-1

Solve for c in the scientific formula C=Wtc/1000
Troyanec [42]

C = Wtc/1000

1000C = Wtc

Wtc = 1000C

W = (1000C) / (tc)


This is assuming that C and c are not the same.

If they are the same, we have:


W = (1000) / t, provided ,that C and c are not equal to 0.

15 POINTS PLEASE HELP!!! WILL MARK BRAINLIEST
dangina [55]

Given: ∠ DEF

To construct: ∠TSZ ≅ ∠DEF

Construction: Consider the attachment

Step-01: Draw a line XY and choose a point S on it as a vertex of the required angle. Further marks point T such that DE = ST

Step-02: Take an arc AB from point E in ∠DEF of any length and draw at point S which cuts at point P on XY line.

Step-03: Take another arc of length AB from point B in ∠DEF and draw from point P which cuts to the previous arc at Q.

Step-04: Now, join the point SQ and extend up to Z such that EF = SZ

Hence, ∠ TSZ will be the required congruent constructed angle to∠DEF
