Answer: D: x = {-3, -1, 1}
<u>Step-by-step explanation:</u>
Domain refers to the x-values of the coordinates.
Coordinates are in the form (x, y) so we are looking for the values on the left side of the parenthesis.
(-3, -2) --> x = -3
(-3, 0) --> x = -3 <em>already listed above so no need to list it again</em>
(-1, 2) --> x = -1
(1, 2) --> x = 1
the x-values are: -3, -1, & 1
so the domain is: x = {-3, -1, 1}
Answer:
3.49 radians
Step-by-step explanation:
The arc length formula is s = rФ, where r is the radius and Ф is the central angle. We know s and r and need to calculate Ф.
From s = rФ we get Ф = central angle = s/r
Here, that central angle Ф is (31.4 cm) / 9 cm = 3.49 radians
Area of a triangle is = 0.5bh
if the height (h) is 4 less than base (b) then h = b - 4
48 = 0.5(b)(b - 4)
48/0.5 = b² - 4b
96 = b² - 4b
b² - 4b - 96 = 0
(b + 8)(b - 12) = 0
b must be either -8 or 12
since a distance can't be negative that means
the base is 12
