Answer:

m<BAC = 29 degrees

m<BOC = 58 degrees

Step-by-step explanation:

<BAC, <BDC, and <BOC share the same arc.

<BAC and <BDC are inscribed angles, and will have the same angle measure, 29 degrees.

<BAC and <BDC are inscribed angles, so their measure is 1/2 of the measure of the arc.

The measure of arc BC is 58 degrees.

<BOC is a central angle. The angle measure of a central angle is equal to the measure of the arc.

The measure of <BOC is 58 degrees.

Step-by-step explanation:

BDC = BAC

BAC = 29°

BOC = 2BDC

= 2×29

= 58°

Consider the radical equation (3√6-x)+4=-8. Explain why the calculation in Problem 1 does not produce a solution to the equation

murzikaleks [220]

Answer:

See explanation below

Step-by-step explanation:

First we will solve the radical equation (which I guess was problem 1),

Let's start by simplifying it:

$3\sqrt{6-x}+4=-8\\ 3\sqrt{6-x}=-8-4\\ 3\sqrt{6-x}=-12\\\sqrt{6-x}=-4$

Now we will solve the equation by squaring both sides of the equation:

$\sqrt{6-x} =-4\\6-x=-4^{2} \\6-x=16\\-x=16-6\\-x=10\\x=-10$

So the calculation for x was that x = -10

However, this does not produce a solution to the equation: When we plug this value into the radical equation we get:

$3\sqrt{6-x} +4= -8\\3\sqrt{6-(-10)} +4=-8\\3\sqrt{16}+4 = -8\\ 3(4)+4 = -8\\12 + 4 = -8$

This happens because when we first squared both sides of the equation in the first part of the problem we missed one value for x (remember that all roots have 2 answers, a positive one and a negative one) while squares are always positive.

When we squared the root, we missed one value for x and that is why the calculation does not produce a solution to the equation.

Guthrie made the input-output table shown below.

Inga [223]

9514 1404 393

Answer:

C 3x +1 = y

Step-by-step explanation:

x-values increase by 1 from row to row.

y-values increase by 3 from row to row.

The slope of the linear function is the ratio of the y-increase to the x-increase:

m = ∆y/∆x = 3/1 = 3

The only offered choice with an x-coefficient of 3 is ...

C 3x +1 = y

If you check this against the table entries, you find it fits.

3(1) +1 = 4

3(2) +1 = 7

and so on.

Who is bigger 0.17 or o.165

Zepler [3.9K]

So... 0.170
0.165.

So at first it was 0.17. But if you add that imaginary 0 its 0.170. So now the answer is 0.170. Hope this helps! ;)
