Answer:
The value of f(3) is -2.
Step-by-step explanation:
This is a recursive function. So
Now, we find f(2) in function of f(1). So
Now, with f(2), we can find the value of f(3).
The value of f(3) is -2.
For a segment AB, the coordinates of the middle point C are:
xc=(xa+xb)/2,
yc=(ya+yb)/2.
Now, you know points A and C. Thus we get:
xb=2×xc-xa
yb=2×yc-ya
With numerical values:
xb=2×2-(-1)=4+1=5
yb=2×3-(-5)=6+5=11
Answer: B(5, 11)
Answer:
<h3>Solution: Length of the rectangular farmland =1km</h3><h3> :Breadth of the rectangular farmland =1/2km</h3>
1km= 1000m, 1/2km =500m
Area=Length×Breadth
=1000x500m2=500000m2
=50×10000m2=50 hectares

We are given a circle with center O.
We can see that we have a radius OB of given circle.
OC and OE are another two radii.
EC is a diameter of the circle.
<em>Diameter is the segment that cut the circle at two points and passes through center.</em>
AB is a tangent of the given circle.
<em>A tangent is a segment that cut a circle at one point only.</em>
But the chord is GD.
<em>A chord of a circle is the segment that cut a circle at two points.</em>
<h3>Therefore, a chord in circle O is GD.</h3><h3 />
