Answer:
dy/dx = -1/
Step-by-step explanation:
y = 1/x
dy/dx = d/dx(1/x)
=> dy/dx = d/dx(
)
=> dy/dx = -
=> dy/dx = -1/
Answer:
I don't understand what the means
The circumference of this circle is c=94.25ft
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
3y=8x
Explanation:
If y varies directly with x then
y=c⋅x for some constant of variation c
If (x,y)=(14,23) is a solution to this equation, then
23=c⋅14
→c=23⋅41=83
So
y=83x
or (clearing the fraction)
3y=8x
