Answer:
Circumference: C = 7.5π m. This is approximately 23.56 m
Total fencing cost: $215.76
Step-by-step explanation:
Ashton walks along the diameter of the garden, which is 7.5 m.
The circumference formula C = πd yields C = 7.5π m. This is approximately 23.56 m, which we must round up to 24 m, and which calls for 24 - 1 m pieces at $8.99 each.
The desired fencing would cost (24 m)($8.99/m), or $215.76
Answer:6.28 units sq
Step-by-step explanation:
To find the area of a semi ..circle
Area of semi- circle=1/2πr^2
d=10 r=2
A=1/2×3.14×2×2
A=6.28 units sq
Answer:
Therefore the angle of intersection is 
Step-by-step explanation:
Angle at the intersection point of two carve is the angle of the tangents at that point.
Given,

and 
To find the tangent of a carve , we have to differentiate the carve.

The tangent at (0,0,0) is [ since the intersection point is (0,0,0)]
[ putting t= 0]

Again,

The tangent at (0,0,0) is
[ putting t= 0]

If θ is angle between tangent, then






Therefore the angle of intersection is
.
F(x)•g(x)=
2(2x+1)=
4x+2
4(0)+2= 2
f(x)•g(x)=
2(2x+1)=
4x+2=
4(2)+2= 10
Sin α = 12/13 opposite/hypothenue
cos α = 5/13 adjacent/hypothenue
tan α = 12/5 opposite/adjacent
