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. False. 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. True. 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. True. 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.
