I don’t know, what did he say?
So the equation of a circle is (x - h)² + (y - k)² = r² where (h,k) are the coordinates of the center of the circle and r is the radius. The diameter of a circle is a line that goes from one point of the circle to the other through the center of the circle. Well the center would be midway through the diameter so use midpoint formula to find the center which is (h,k) Mid point formula is both given x's added together divided by 2 for h and both y coordinates added together divided by 2 to find k
(10+0)/2
10/2= 5
(12+2)/2
14/2 = 7
so the center of the circle is (5,7) now use distance formula using the center and one of the points to the radius
√((5-10)²+(7-12)²)
√(-5²+ -5²)
√(25 + 25)
√50 is the radius
Now plug all found information into circle equation
(x-5)² + (y-7)² =50 note the end is 50 because the circle equation is radius squared and since the radius is √50, radius² is 50.
Answer is c
Answer:
240 Pints
Step-by-step explanation:
To convert 30 gallons into pints you need to multiply 30 by the conversion factor in order to get the volume amount from gallons to pints.
The following interval notation are as follows;
(a) Domain:(-2,∞)
(b) Range: (-4,4)
(c) Interval(s) on which f(x) is increasing: (0,4)
(d) Interval(s) on which f(x) is decreasing: (2,6)
(e) Interval(s) on which f(x) is constant:(2, ∞)
(f) Local maxima: (0,4)
(g) Local minima:( 0,-6)
<h3>What is function?</h3>
The function is a special relationship between inputs (i.e. domain) and their outputs (known as code domain) where each input has exactly one output and the output can be traced back to that input.
There are many types of functions in mathematics. Some important types are:
- Injection function or One-to-one function: If each domain has a mapping between two sets.
- Surject functions or Onto function: When more than one element is connected from domain to domain.
- Polynomial function: A function consisting of polynomials.
- Inverse Functions: A function that can invert another function.
These were some examples of functions. It should be noted that there are several other functions such as function, algebraic functions, etc.
