10y^7
You multiply the y^4 by y^3
2y^7 x 5
Multiple the 5 by 2
Answer: 10y^7
The area of the square would be 14 x 14 = 196
The area of the circle would be PI x r^2, r = 7 m
area = PI x 49 = 153.86
Area of shaded region: 196 - 153.86 = 42.14 square meters
Answer:
W₂ is three times W₁ (W₂ = 3W₁)
Step-by-step explanation:
Applying,
W = ke²/2............. Equation 1
Where W = workdone in stretching the spring, k = spring constant, e = extension.
For W₁,
W₁ = ke₁²/2
Given: e₁ = 30-20 = 10 cm = 0.1 m
Substitute these value into equation 1
W₁ = k(0.1²)/2
W₁ = 0.005k Joules
For W₂,
W₂ = (ke/2)-W₁
Given: e = (40-20) = 20 cm = 0.1 m
Substitute these value into equation 1
W₂ = (k×0.2²/2)-0.005
W₂ = 0.015k Joules.
W₂/W₁ = 0.015k/0.005k
W₂/W₁ = 3
Therefore,
W₂ = 3W₁
The function is the Sine Curve
y = sine (x)
