I thought it would be c but try b or a
Answer:

Step-by-step explanation:
We use the formula for a circle with center at (0, -1), that goes through the (x, y) point (-1, -2):

Therefore, the equation of this circle can be written as:

9514 1404 393
Answer:
graph: lower right
π units to the right of the graph of f(x)
Step-by-step explanation:
The transformation of f(x) to f(x-h) is a translation to the right by h units.
Here, the function f(x) = 1/2cos(x) is transformed to f(x-π) = 1/2cos(x-π), so is a translation of f(x) to the right by π units.
The graph of the translated function is shown below.
Answer:
and 
Step-by-step explanation:
We have been given that about 75,000 people visit Paris, France. We are asked to write two equivalent expressions that could be used to find the number of people that visits over a 5- day period
.
To find the number of people over a 5-day period, we will multiply 75,000 people by 5 as:

Commutative property of multiplication states that we can multiply numbers in any order.
Upon switching the order while multiplying, we will get:

Therefore, our required equivalent expressions would be
and
.
