Answer:
72 square inches.
Step-by-step explanation:
Convert feet and inches.
36 feet = 36*12 inches
=432 inches
Width of the floor; Converted from feet to inches:
32 feet = 32*12 inches
= 384 inches
Calculate how many times the length (l) has been scaled down.
432 inches of length has been reduced to 9 inches.
Now the length has been scaled down 48 times.
Scale down the width (w) 48 times.
The width of the scale drawing = 8 in
Area of the Scale drawing = Scaled down length * Scaled down width
The answer is 1.
Im too lazy to show the work, but heres how I checked
-7(1 + 2) = -14 - 7
-7 + (-14) = -14 - 7
-21 = -21

Initial water volume + marble volume = final water volume
We have the following equation:
y = -2x2 + 2x + 2
We look for the vertex of the parabola. For this, we derive the given equation:
y '= - 4x + 2
We match zero:
0 = -4x + 2
We clear x:
4x = 2
x = 2/4
x = 1/2
We evaluate the function for x = 1/2:
y = -2 * (1/2) ^ 2 + 2 * (1/2) + 2
y = 2.5
The vertice of the parabola is:
(x, y) = (1/2, 2.5)
We now look for the value of the function for x = 6:
y = -2 * (6) ^ 2 + 2 * (6) + 2
y = -58
Answer:
The vertice of the parabola is:
(x, y) = (1/2, 2.5)
the value of the function for x = 6 is:
y = -58
