\bf \textit{arc's length}\\\\ s=r\theta ~~ \begin{cases} r=radius\\ \theta =angle~in\\ \qquad radians\\ \hrulefill\\ r=3\\ \theta =\frac{7\pi }{3} \end{cases}\implies s=3\cdot \cfrac{7\pi }{3}\implies s=7\pi

Answer:

D. 7pi inches

Step-by-step explanation:

The value of the arc length is calculated by the following formula,

s = rt

<u>Where:</u>

  1. s is the arc length
  2. r is the radius of the circle
  3. t is the central angle in radians

Since we were given both the central angle and the radius we can just plug it into the formula and solve for the arc length.

s = \frac{7\pi }{3} *3

s = 7\pi

Now we can see that the arc length has a value of 7\pi , making the answer of this question <u>D. 7pi inches</u>

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

Answer:

  -0.16

Step-by-step explanation:

The 'a' value can be found by looking at the difference between the y-value of a point 1 unit from the vertex, and the y-value of the vertex.

Here, that is a negative fraction of a unit. If we assume the value is a rational number that can be accurately determined from this graph, then we can find it by looking for a point where the graph crosses a grid intersection. It looks like such grid points are (-7, 0) and (3, 0). The vertex is apparently (-2, 4), so the vertex form of the equation is ...

  y = a(x +2)^2 +4

Using the point (3, 0), we have ...

  0 = a(3 +2)^2 +4 . . . . . fill in the values of x and y

  -4 = 25a . . . . . . . . . . subtract 4; next, divide by 25

  a = -4/25 = -0.16

Answer:

14/13

Step-by-step explanation:

19/13-5/13=14/13
