Answer:

Decide if estimation is appropriate. Estimating a fraction will give you the gist of the fraction. However, you'll seldom guess the exact answer with it. If you only need a general idea of the answer, estimations are helpful. However, if you need to give an exact answer, solve your equation with exact measurements. A good estimation will convey the general idea across quickly, and won't attempt to pass itself off as an exact answer.

1. Let a be a positive real number. In Part (1) of Theorem 3.25, we proved that for each real number x, jxj < a if and only i

krek1111 [17]

Answer:

(a)

if $x \geq 0$ then $x \geq a$ and if x<0 then $-x > a$

(b)

That is straightforward from what you showed on theorem 3.25

(c)

Following the same ideas from (a) x>a or -x > a.

Step-by-step explanation:

Remember how we define the absolute value of a number.

(a)

In general

$|x| = x \,\,\,\text{if} \,\,\,\, x \geq 0 \\|x| = -x \,\,\,\text{if} \,\,\,\, x < 0$

Therefore if $|x| \geq a$ you have two cases, if $x \geq 0$ then $x \geq a$ and if x<0 then $-x > a$

(b)

That is straightforward from what you showed on theorem 3.25

(c)

Following the same ideas from (a) x>a or -x > a.

What is the measure of the arc from A to B that does not pass through C?

sergeinik [125]

Applying the inscribed angle theorem, the measure of the arc from A to B is: 100 degrees.

<h3>What is the Inscribed Angle Theorem?</h3>

The inscribed angle theorem states that an inscribed angle in a circle is half the central angle.

Angle BAC = 40 degrees, so, central angle = 80 degrees. Arc BC would also be 80 degrees.

Measure of arc AC through point B = 180 degrees.

Arc AB = 180 - 80 = 100 degrees.
