Well the real answer is three hundred-ninety three point five. So numbers around it could be three hundred and fifty and four hundred. An estimate could be three hundred and seventy five.
To check if an expression is indeed a function, you'd use the vertical line test, if it passes, then it IS a function.
now, if it passes the horizontal line test, doesn't mean much function wise, what the dickens is up with the horizontal line test anyway?
well, if the graph, does indeed pass the vertical line test first, is a function, IF then it also passes the horizontal line test, it means, is not only a function but a one-to-one function, meaning there's a unique x-coordinate value for every unique y-coordinate value.
note:
only one-to-one functions have an inverse expression that is also a function.
Answer:
YES
Step-by-step explanation:
Answer:
The answer to your question is See the attachment
Step-by-step explanation:
Equation
(x - 8)² + (y + 5)² = 4
Process
1.- Write the standard equation of the circle
(x - h)² + (y - k)² = r²
2.- Find the center
The center are the letters h and k
h = 8 k = -5
3.- Find the radius
r = 2
4.- Graph the circle ( i will use geogebra)
See below
<span>The sum of angles CAD and DAB is 180 degrees. This is because they are all on a straight line (because points CAB are colinear) and angles on a straight line add up to 180 degrees.</span>
