Answer:
Divide C values/T values that will tell if it is constant or not and that is the reason.
Answer:
a) ⅓ units²
b) 4/15 pi units³
c) 2/3 pi units³
Step-by-step explanation:
4y = x²
2y = x
4y = (2y)²
4y = 4y²
4y² - 4y = 0
y(y-1) = 0
y = 0, 1
x = 0, 2
Area
Integrate: x²/4 - x/2
From 0 to 2
(x³/12 - x²/4)
(8/12 - 4/4) - 0
= -⅓
Area = ⅓
Volume:
Squares and then integrate
Integrate: [x²/4]² - [x/2]²
Integrate: x⁴/16 - x²/4
x⁵/80 - x³/12
Limits 0 to 2
(2⁵/80 - 2³/12) - 0
-4/15
Volume = 4/15 pi
About the x-axis
x² = 4y
x² = 4y²
Integrate the difference
Integrate: 4y² - 4y
4y³/3 - 2y²
Limits 0 to 1
(4/3 - 2) - 0
-2/3
Volume = ⅔ pi
Answer:
<u>It should be 128 inches or 10.67 feet tall</u>
Step-by-step explanation:
Real size of the monument = 160 feet tall
Scale used by Tonya = 4 inches equal to 5 feet
Scale model of the monument = Real size of the monument / Scale used
Proportion between real monument and scale model = 160 / 5 = 32
It means that the proportion between the real monument and the scale model is 32
Scale model height = Proportion * scale used
Scale model height = 32 * 4
<u>Scale model height = 128 inches</u>
<u>Scale model height = 128/12 = 10.67 feet (12 inches = 1 feet)</u>
Answer:
The answer is C) 2
