Complete Question
If minor arc AB measures 9 inches, what is the length of the radius of circle C? Where the radians is 0.75 radians
If necessary, round your answer to the nearest inch. 6 inches 12 inches 18 inches 24 inches
Answer:
12 inches
Step-by-step explanation:
The formula for Arc length =
Arc length = r θ
θ = 0.75
Arc length = 9 inches
Hence:
r = 9/ θ
r = 9/0.75
r = 12 inches
Answer:
True.
Step-by-step explanation:
y = -3x + 20
Put x as 5, then y output should be 5.
y = -3(5) + 20
y = -15 + 20
y = 5
True, the line with slope -3 passes through points (5, 5).
Answer:
a = 0.
Step-by-step explanation:
2(a - 4) = 2a - 8 + 4a
2a - 8 = 2a - 8 + 4a
2a - 2a - 4a = -8 + 8
-4a = 0
a = 0.
We have the following system of equations:
y = -6x-6
y = x2-5x-6
Matching we have:
x2-5x-6 = -6x-6
Rewriting we have:
x2-5x-6 + 6x + 6 = 0
x2 + x = 0
Rewriting:
x (x + 1) = 0
The solutions are:
x = 0
x = -1
For x = 0
y = -6 (0) -6 = 0-6 = -6
y = -6
For x = -1
y = -6 (-1) -6 = 6-6 = 0
y = 0
The solutions are:
(x, y) = (0, -6)
(x, y) = (- 1, 0)
Answer:
The solutions of the system are:
(-1, 0) and (0, -6)
