Answer:

Step-by-step explanation:
Odd functions follow the relation of

Lets check for the most trivial value, does

Well these values both equal 0, so this is correct!
What about another value?

In-fact this is strictly defined for all values of sin. Meaning that this is an odd function.
Answer:
Part a) In Geneva the watch is cheaper
Part b) The watch in Geneva is
cheaper than the same watch in Manchester
Step-by-step explanation:
<u><em>The question is</em></u>
a) In which city is the watch cheaper?
b) By how much is it cheaper (in £)?
Part a)
Transform
in order to work with the same currency and make the comparison
If 

Now we can make the comparisons:
In Geneva the watch costs
and
in Manchester it costs


therefore
In Geneva the watch is cheaper
Part b)
If we want to know by how much is cheaper, subtract from the expensive price the value of the cheaper price
Therefore
The watch in Geneva is
cheaper than the same watch in Manchester
Answer:
21.98 yards
Step-by-step explanation:
In this question, we are asked to get the distance from a flag placed at the center of a garden to the edge of that garden.
From the definition of circle terms, the radius of a circle is simply the distance from the center of the circle to any part of the circumference(in this case, edge of the circle)
Since we are given the circumference of the circle, all we need to do to know the distance is to look for the value of the radius. Hence, we use the formula that links the circumference of a circle and the radius of the circle.
Mathematically, the circumference of a circle C=2πr
The value π is 22/7
138.16 = 2 * 22/7 * r
44r = 7 * 138.16
r = (7 * 138.16)/44
r = 21.98 yards
Hence the distance from the center of the circular garden to its edge is 21.98 yards
Answer:
=13/28
Step-by-step explanation:
you can also use symbolab for these types of math problems<3
Use the distributive property and collect terms.
= x·6x -x·8y +y·6x -y·8y
= 6x² -2xy -8y²
