#3 AB and AD are tangent to the circle centered at point C. Find the value of x. *
dezoksy [38]

Answer:

x=4

Step-by-step explanation:

tangent lines from the same point to a circle are congruent in length, so we can say that

5x+8 = 8x-4

5x -5x +8 = 8x - 5x -4

8 = 3x - 4

8+4 = 3x -4 + 4

3x = 12

3x/3 = 12/3

x=4

Find the area of the figure. Use 3.14 for pie . Round your answer to the nearest tenth.
gizmo_the_mogwai [7]

Answer:

538.3

Step-by-step explanation:

First of all find the area of the rectangle

L*W

15*30

450

Now find the area of semi circle

1/2\pi r^{2}

Since radius is half a diameter divided 15 by 2=7.5

1/2\pi 7.5^{2}                            7.5 times 7.5= 56.25

1/2*3.14*56.25

56 times 3.14 is 176.625 now multiply 176.625 by 1/2

Answer is 88.3125

Now add 450 to 88.3125

Final answer: 538.3125

Which line has the greatest rate of change? A line passing through (-1, 4) and (1, 7). A line passing through (1, 3) and (5, 11)
Juliette [100K]

Answer:

A line passing through (1, 3) and (5, 11)

Rate of change = 2

Step-by-step explanation:

  • <em>Rate of change = change in y / change in x</em>
  • <em>r = Δy/Δx</em>

<u>Let's get the rate of change for each line:</u>

A line passing through (-1, 4) and (1, 7).

  • r = (7 - 4) / (1 -(-1)) = 3/2

A line passing through (1, 3) and (5, 11).

  • r =  (11 - 3) / (5 - 1) = 8/4 = 2

A line passing through (1, 1) and (4, -3).

  • r = (- 3 - 1) / (4 - 1) = -4/3

A line passing through (0, 6) and (12, 9)

  • r = (9 - 6) / (12 - 0) = 3/12 = 1/4

<u>Comparing the values of r, we can see the greatest one is</u> 2 for the line passing through (1, 3) and (5, 11)
