It's the right angle. The circumcenter is in half of hypotenuse.
The formula of a midpoint of segment BC:

We have the points B(-2, -2) and C(7, -5). Substitute:

Answer: (2.5, -3.5)
Domain is the set of values of x.
Notice that in the graph x start from origin x=0 and goes till x=4 which shows x is from 0 to 4.
Hence the domain of the function is 0<x≤4.
Similarly y starts from origin and stop at y=40.
So, range is 0<y≤40.
Answer:
2%
Step-by-step explanation:
20% takes 10 years to decay
To find per year decay, we divide the percentage by the number of years, so we get unit rate of years {per year]. Thus we have:
20%/10 = 2% per year
It's that simple.
Hence, the percentage by which the substance decays each year is 2%
Answer:
B. 0.583
Step-by-step explanation:
It is important to note the details already given in the question. Based on those details the answer to the question can be easily determined. Now let us focus on the question given.
Cost price of the product in question = $360
Percentage of gain on the product = 12.5%
Then
amount of gain made on the product = (12.5/100) * 360 dollars
= 450/10 dollars
= 45 dollars
So
The selling price of the product in question = (360 + 45) dollars
= 405 dollars
