Answer:
A = 5.76 cm²
Step-by-step explanation:
3.2 cm x 1.8 cm = 5.76 cm²
= x(8 -8) +(10 +13)
= 0 +23
= 23
Selection D is appropriate.
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
Step-by-step explanation:
No they dont because jogger A turns 5 degrees more than jogger B and jogger B turned at 115 degrees.
