Step-by-step explanation:
what is the problem ? what needs to be done ?
all that you are showing here is the definition of a number range.
it means all numbers, for which 1.3 is smaller or equal.
in short, all numbers that are greater or equal to 1.3.
SOLUTION
The question simply means that we should find the sum to infinity of the geometric series.
The formula of sum to infinity of a geometric serie is given by

Where

So, this becomes

Therefore, option b is the correct answer
right 3 units down 5 units

right 3 units = (3,0)
down 5 units = (0,-5)
vertex = (h,k) therefore.

Then convert the vertex form into standard form for the equation in the choice.

Thus, the answer is B.
find the circumference of the circle then multiply it by 24
