Answer:
Because 6= 18/3
the central angle is 360/3=120 degrees
Step-by-step explanation:
Where did the decimal stop at ?
Answer:
18a^2
Step-by-step explanation:
Multiply the numbers together. Multiply the variables together.
(-3a)(-6a) = (-3) * (-6) * a * a = 18a^2
-3 times -6 = 18 since negative times negative is positive, and 3 * 6 = 18.
Also a * a = a^2.
Answer: 18a^2
(x + 9) (x - 9)
follow the FOIL method
first
x(x) = x^2
outside
x(-9) = -9x
inside
9(x) = 9x
last
9(-9) = -81
x² - 9x + 9x - 81
simplify: x² - 81
x² - 81 is your answer
hope this helps
it is not - 18, because you are multiplying, not adding, and even if you are adding, the answer wouldn't have a -18
hope this helps
Answer:
The wedge cut from the first octant ⟹ z ≥ 0 and y ≥ 0 ⟹ 12−3y^2 ≥ 0 ⟹ 0 ≤ y ≤ 2
0 ≤ y ≤ 2 and x = 2-y ⟹ 0 ≤ x ≤ 2
V = ∫∫∫ dzdydx
dz has changed from zero to 12−3y^2
dy has changed from zero to 2-x
dx has changed from zero to 2
V = ∫∫∫ dzdydx = ∫∫ (12−3y^2) dydx = ∫ 12(2-x)-(2-x)^3 dx =
24(2)-6(2)^2+(2-2)^4/4 -(2-0)^4/4 = 20
