Answer:

I suppose it should be

6b² and (6b²)²

or

6b² and 36b^{4}

Step-by-step explanation:

(a+b)² = a² + 2ab + b²

therefore

(6b²+2a)² = (6b²)² + 12ab² + 4a²

In the diagram A, B, and C are the points on the circle. Use the diagram to prove the theorem which states that:
nevsk [136]

9514 1404 393

Explanation:

Here's one way to go at it.

Draw segments AB and CO. Define angles as follows. (The triangles with sides that are radii are all isosceles, so their base angles are congruent.)

  x = angle OAB = angle OBA

  y = angle OAC = angle OCA

  z = angle OBC = angle OCB

Consider the angles at each of the points A, B, C.

At A, we have ...

  angle CAB = x + y

At B, we have ...

  angle CBA = x + z

At C, we have ...

  angle ACB = y + z

The sum of the angles of triangle ABC is 180°, as is the sum of angles in triangle ABO. This gives ...

  x + x + ∠AOB = (x+y) +(x+z) +(y+z)

  ∠AOB = 2(y+z) = 2∠ACB

This shows ∠AOB = 2×∠C, as required.

If f(x) = -x + 5 and g(x) = x^2, what is (g° (-1)?
ipn [44]

Answer:

(g\circ f)(-1)=36

Step-by-step explanation:

We are given the two functions:

f(x)=-x+5\text{ and } g(x)=x^2

And we want to find:

(g\circ f)(-1)

This is equivalent to:

=g(f(-1))

So, evaluating f(-1) first, we acquire:

f(-1)=-(-1)+5=6

Then by substitution:

=g(6)

So:

=(6)^2=36

Therefore:

(g\circ f)(-1)=36

Your answer is indeed correct.
