The correct answer for the question that is being presented above is this one:
(1)
The triangle shows and equilateral triangle. Equilateral triangle has the same length of sides and angles.
60 = 1.5x
x = 40 degrees
7.1 = y + 3.4
y = 3.7 cm
(2) Isosceles Triangle
65 = 13x
x = 5 degrees
y + 2/3 = 7/8
y = 7/8 - 2/3
y = 21 - 16 / 24
y = 5/24 in
(3)
12 = x + 3.8
x = 8.2mm
The formula for the volume of a pyramid is,
V=1/3Bh
Since the base of the pyramid is a square, the base area is 11^2
which equals 121 sq. units
So, substitute 121
for B
and 6 for h, in the formula.
V=1/3(121)(6) = 242 cu. units
Or alternatively 1/3(11^2)(6) = 242 cu. units
Step-by-step explanation:
The domain of a function is all possible input x-values, and the range of function is all possible output y-values.
The domain of this function is (-6, 3) and the range is (-5, 5). Those are written like this:
D: (-6, 3)
R: (-5, 5)
I suppose I'll pick the first one: "The domain is (-6, -1)." This is wrong as the domain on the graph shown is (-6, 3).
