How do you solve (Arc)QPT if <QZT = 120
yuradex [85]
By definition, the arc length is given by:
 arc = R * theta * ((2 * pi) / 360)
 Where,
 theta: angle in degrees
 R: radio
 We have then:
 (Arc) QPT if <QZT = 120:
 theta = 360-120 = 240 degrees
 R = 13.5 units
 Substituting values we have:
 (Arc) QPT = R * theta * ((2 * pi) / 360)
 (Arc) QPT = (13.5) * (240) * ((2 * pi) / 360)
 (Arc) QPT = 56.55 units
 Answer:
 
(Arc) QPT = 56.55 units

The table shows ordered pairs of the function . What is the value of y when ?
LiRa [457]

Answer:

(B) -8

Step-by-step explanation:

Given the 2-column table below:

\left|\begin{array}{c|c}x&y\\--&--\\-3&14\\-1&10\\1&6\\4&0\\8&?\\10&-12\end{array}\right|

Taking the pair (-3,14) and (-1,10)

Slope, m=\dfrac{10-14}{-1-(-3)} =\dfrac{-4}{2} =-2

Taking the pair (1,6) and (4,0)

Slope, m=\dfrac{0-6}{4-1} =\dfrac{-6}{3} =-2

Since the slope is constant, the table represents a linear function whose slope is -2. Therefore:

Taking the pair (8,y) and (4,0)

Slope, m=\dfrac{0-y}{4-8} =-2

\dfrac{-y}{-4} =-2\\y=-2*4=-8

Therefore, the value of ? on the y-column is -8.

Here is a table of values y=f(x).
Mariulka [41]

A. <u>False.</u> The range of f(x) is the set of values it can produce. In the table, f(x) produces values from 0 to 3. However, the range of all real numbers is all rational numbers, basically from -\infty to \infty, not just a few numbers in-between. So, the range of f(x) is not all real numbers.

B.  <u>True.</u> Looking at the table, when x=-3, f(x)=2. This is another way of saying that f(-3)=2, which is what B is saying.

C. <u>True.</u> The domain of f(x) is the set of values of x that produce some output in f(x). Looking at the table, all of the x values listed on it are in the set \{-5, -3, 0, 2, 6, 7, 9, 10, 13\}, which is what C is saying.

D. <u>False.</u> Looking at the table, when x=0, f(x)=3. This is another way of saying that f(0)=3, which is <em>not </em>what B is saying.
