Answer:
y= b+ 3a
Step-by-step explanation:
Given data
We are required to rent a bike and a helmet
le the flat fee for bike rental be a
and the flat fee helmet be b
let the number of hours be h
and let the total cost be y
So
y= b+ah
for h = 3
tThen the expression for the total is given as
Each petal of the region 
is the intersection of two circles, both of diameter 10. Each petal in turn is twice the area of a circular segment bounded by a chord of length 
, which implies the segment is subtended by an angle of 
. This means the area of the segment is
This means the area of one petal is
, and the area of is four times this, or 
.
Meanwhile, the area of
is simply the area of the square minus the area of , or 
.
So
(provided these regions are indeed disjoint; it's hard to tell from the picture)
This means the area of one petal is
Meanwhile, the area of
So
