Answer:
30.113
Step-by-step explanation:
r(t) = (t³, 2 sin t)
The distance traveled is the length of the path (arc length):
L = ∫ₐᵇ √((dx/dt)² + (dy/dt)²) dt
L = ∫₁ᵖⁱ √((3t²)² + (2 cos t)²) dt
L = ∫₁ᵖⁱ √(9t⁴ + 4 cos²t) dt
Using a calculator:
L ≈ 30.113
Notice that distance is not the same as displacement. If we wanted to find the displacement:
r(π) = (π³, 0)
r(1) = (1, 2 sin 1)
Δr = √((π³ − 1)² + (0 − 2 sin 1)²)
Δr ≈ 30.053
and can the answer be squared

Answer:
Area = 104 m²
Step-by-step explanation:
the figure is composed of a rectangle and a triangle
area of rectangle = length × breadth = 10 × 8 = 80 m²
area of triangle = × base × perpendicular height
the base of the triangle is opposite the 8 m side of the rectangle and is 8 m
the perpendicular height of the triangle is 6m , then
area of triangle = × 8 × 6 = 4 × 6 = 24 m²
sum the areas of the two parts
area = 80 + 24 = 104 m²
Answer:
7/3x + 2/3 = 7/9x - 5/6
7/3x - 7/3x + 2/3 = 7/9x - 7/3x - 5/6 (7/9x-7/3x--->7/9x-21/9x---> -14/9x)
2/3= -14/9x - 5/6
2/3+5/6 = -14/9x - 5/6 + 5/6 - (2/3 + 5/6---> 4/6 + 5/6---> 9/6 ----> 3/2)
3/2 = -14/9x
3/2 / -14/9 = -14/9x / -14/9 - (3/2 / -14/9 ------> 3/2 x -9/14 ----->
- 27/28)
-27/28 = x
Step-by-step explanation:
4
pound of peanuts equally. What fraction of a pound of peanuts does each person receive? Enter your answer in simplest form.
Answer:
1/8 lb
Step-by-step explanation:
Each person gets 1/6 of the total amount, so ...
(1/6)(3/4 lb) = 3/24 lb = 1/8 lb
Each person gets 1/8 pound of peanuts.
