Since the height is different on both ends, we can assume that the wall is a trapezoid. Knowing that, we can replace the measures we know in the formula and our onky variable is the length of the wall - we only need to isolate it.
A= ((b+B)h)/2
26.4=((2+2.4)h)/2
52.8=4.4h
h=12
The equation describes a function whose maximum value is 5. The data set describes a function whose maximum value is also 5. Comparing the maximum values, we must conclude ...
... It is the same for both functions.
_____
Please note that the premise is that g(x) is a quadratic function. It is definitely NOT a quadratic function in the usual sense of the term.
Answer: height = 6, radius = 8, Volume = 401.92
Explanation:
Height = 6 given
Find radius:
Use Pythagorean’s theorem to find the side of the right triangle:
a^2 + b^2 = c^2
b^2 = c^2 - a^2
b^2 = 10^2 - 6^2
b^2 = 100-36
b^2 = 64
b = 8
And since length b is also the radius of the circle then radius = 8
Find volume:
V = pi x r^2 x h/3
V = 3.14 x 8^2 x 6/3
V = 3.14 x 64 x 2
V = 401.92
Domain is ur x values
y = 2x...when x = -1
y = 2(-1)
y = -2.....(-1,2) satisfies this equation
y = 2x....when x = 0
y = 2(0)
y = 0....(0,0) satisfies it
y = 2x....when x = 1
y = 2(1)
y = 2....so (1,2) satisfies it
y = 2x....when x = 2
y = 2(2)
y = 4....(2,4) satisfies it
y = 2x...when x = 3
y = 2(3)
y = 6.....(3,6) satisfies it
y = 2x...when x = 4
y = 2(4)
y = 8.....(4,8) satisfies it
Answer:
D. false; if a = 1, b = 2, and c = 3, then 1(2 + 3) ≠ 1(2) + 2(3)
Step-by-step explanation:
A is false, because the a is being distributed/ being multiplied to all terms inside the parenthesis, and not the term b.
B is also false. There is no indicated negative signs.
C is also false because 1(1 + 1) is EQUAL to 1(1) + 1(1)
D is true.
