The First two coefficients are positive because they are on the positive side of the y-axis.
The Last two are on the negative side of the y-axis. B is the closest to zero as the wider the graph is, the lower the coefficient is.
The coefficient with the greatest value would be D
Answer:
4x2 + 23x – 72
= (4x - 9)(x+8)
Step-by-step explanation:
It would be 80 because 2 times 120 is 240. 240 divided by 3 is 80
Answer:
The work done is 202.50Nm
Step-by-step explanation:
Given
Required
The work done
First, we calculate the spring constant (k)
So:
The work done using Hooke's law is:
This gives:
Rewrite as:
Integrate
This gives:
Convert to Nm
Answer:
Step-by-step explanation:
The shape above is a composite shape having two different shapes like rectangle and semi- circle
Area of rectangle=Length × Breadth
Area of semi circle=1/2πr^2
To find the area of the rectangle naw
Length of the rectangle=6.6
Width of the rectangle=4
A=6.6×4
A=26cm^2
Area of semi-circle=1/2
Diameter of the shape =4cm
Radius=2cm
A=1/2×3.14×2cm x2cm
A=6.28cm^2
Area of the shape=26+6.28cm^2
Area=32.28 to 2 dp
