(g\circ f)(x)=g(f(x))\\\\\text{We have}\ f(x)=3x-2\ \text{and}\ g(x)=x^2.\ \text{Substitute:}\\\\(g\circ f)(x)=(3x-2)^2\\\\(g\circ f)(3)\to \text{put the value of x = 3 to the equation of the function}\\\\(g\circ f)(3)=(3\cdot3-2)^2=(9-2)^2=(7)^2=7\cdot7=49\\\\Answer:\ \boxed{(g\circ f)(3)=49}

The completed construction of a regular hexagon is shown below. Explain why ACF is a 30º-60º-90º triangle.
LuckyWell [14K]

We know that one regular hexagon is consist of the six equilateral triangles.

One of this is ΔAFM every angle in this triangle worth 60°, according to this

∡AFM=60°.

ΔABC is isosceles triangle with angle ∡ABC=120°, because every interior angle in regular hexagon worth 120°.

Angles ∡BAC=∡BCA=30°. Total sum of angles in one triangle is 180°.

∡ACF≅∡BCA=30° at the end we can conclud that angle ∡FAC=90° WHY?

Good luck!!!

PLEASEE Can someone help me with this and show the work
Orlov [11]

Answer:

The vertex form is: y =  3(x-2)^2 + 7 . The vertex is (2, 7)

Step-by-step explanation:

Write the function: y = 3x^2 - 12x + 11 in vertex form

The vertex form of a quadratic equation is:

y = m(x - a)^2 + b where (a,b) is the vertex

For y = 3x^2 - 12x + 11

Solve for m

y = 3(x^2 - 4x) + 11

Complete the Square:

y = 3(x^2 - 4x + 4) + 11 - 4

y = 3(x - 2)^2 + 7

The vertex then is (2, 7)

Points C and D are equidistant from point A. Complete the following table to prove that AEC≅ AED
inna [77]
To prove that <span>AEC≅ AED, we need to write following proofs or statement reasons.

It is given that points C and D are equidistant to point A. Hence,
</span><span>AD ≅ AC

Next, </span><span>CAE ≅ DAE. AE is the common side or the included side. 
</span><span>
Then, </span><span>AE ≅ EA by Reflexive Property of Congruence as it is congruent to itself.

Lastly, </span><span>EAD ≅ EAC by Symmetric Property of Congruence as these triangles are mirror image of each other.
</span>
Therefore, we can conclude that AEC≅ AED by SSS or Side-Side-Side. That is when all sides of triangles are congruent then both triangles are deemed to be equal.
