Answer:

Step-by-step explanation:
<u>The ordered pairs for the given relation are:</u>
=> {(6,2)(-1,2)(-1,-1)(4,3)}
Domain => x-inputs of the ordered pairs
Domain => (6,-1,4)
Range => y-inputs of the ordered pairs
Range = (2,-1,3)
Since, <em>the values in the domain (-1) are being repeated, this relation is not a function.</em>

The answer to this question is 4y+4
Lets get started :)
The First question:
Diameter = 20 ft
Radius =

of 20 (diameter) = 20 ft
Area formula of a circle is
A =

r²
=

(10)²
=100

ft²
≈ 314 ft²The answer will be the second optionThe Second question:
radius of circle = 12mm divided into 20 sectors area
A =

r²
=

(12)²
= 144

ft²
Divide into 20 equal sector areas =
≈ 22.6 mm²Your answer will be the third optionThe Third Question:
90°, sector area = 36

, Radius = ?



and

cancels out
We can now cross multiply
360 × 36 = 90r²
12960 = 90r²
Divide by 90 on either side

144 = r²
Take squareroot
x = 12 inYour answer will be the third option
Answer:
B: 39 degrees
Step-by-step explanation: The angles in a triangle add up to 180 degrees. 180 - 30 - 24 = 126.
126 = (3x-9).
126 - 9 = 117.
117 / 3 = 39
