Figure out the radius then divide it by two. The diameter is one end of a circle to another.
Answer:
see below
Step-by-step explanation:
7. f(x) = mx + b; b acts as the vertical shift moving the graph up if b is positive and down if b is negative.
f(x) = x-2 has shifted the graph of f(x) down 2 units.
g(x) = x + 7 has shifted the graph up 7 units.
If f(x) is changed to g(x) the vertical shift has gone from -2 to + 7 or (7-(-2) = 9 units up
8. f(x) = mx stretches the graph by a factor of m if m > 0 and compresses the graph by a factor of m if 0<m<1
f(x) = 3x stretches the graph by a factor of 3.
g(x) = 1/4x compresses the graph by a factor of 1/4
8 because 2 times 5 is ten
The correct option is : no mode
<u><em>Explanation</em></u>
The given data set is: 
The <u>mode is the number that is repeated more often</u> than any other number in the data set.
But here we can see that all the numbers in this data set are different. That means <u>they appear only once</u>.
So, there will be 'no mode' in this set.
