Answer:

f(x)=(x-5)^{2}+19

Step-by-step explanation:

we have

f(x)=x^{2}-10x+44

Group terms that contain the same variable, and move the constant to the opposite side of the equation

f(x)-44=x^{2}-10x

Complete the square. Remember to balance the equation by adding the same constants to each side.

f(x)-44+25=x^{2}-10x+25

f(x)-19=x^{2}-10x+25

Rewrite as perfect squares

f(x)-19=(x-5)^{2}

f(x)=(x-5)^{2}+19

Volume of sphere = 4/3 x pi x r^3

904.32 = 4/3 x pi x r^3

Divide both sides by 4/3

678.4 = pi x r^3

Divide both sides by pi:

216 = r^3

Take the cubic root of both sides

R = 6

I need help on c and d please

A

We can't really do this without seeing 28, but I can give you an educated guess. The best way for me to proceed is to solve c.

The conjecture is that x = a + b. You should always find that to be true. C is the clincher.

Here's how you do that.

x + c = 180o That's true because all straight lines have 180o. If two angles make up the straight line that means that they are always equal to 180o So x + c = 180o

Now we move to the next step. All triangles also have 180o. That means that a + b + c = 180o

So we have two conditions that equal 180o. Equalities can be equated to one another.

a + b + c = x + c Subtract c from both sides.

a + b = x.

Study what has happened. Put in mathese, the two remote interior angles equal the exterior angle, which is what you are trying to prove.

Summary

a cannot be solved without 28

b you should say that the two remote angles (a and b) will always total x

c The proof is provided for you.
