The equation of a circle with center (h,k) and radius r is
convert it to that form by comleting the square for the x and y terms
or, we can just expand what we know
expand
and make it equal to 0
so expanding we get
minus m^2 from both sides
arranging in decreasing power order with m² at the end
that is option A
answer is A
Answer:
D
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
To calculate m use the slope formula
m = ( y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (3, 6) and (x₂, y₂ ) = (8, 4)
m = = - , hence
y = - x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (8, 4), then
4 = - + c ⇒ c = 4 + =
y = - x + ← equation of line
Answer:
touches
crosses
Step-by-step explanation:
is said to be a zero of a function if
A zero say has a "multiplicity" equal to , if the factor appears in the polynomial.
When a real zero of a polynomial function is of even multiplicity, the graph of <u>touches</u> the x-axis at , and when it is of odd multiplicity, the
graph of <u>crosses</u> the x-axis at .
0.12b+0.40=19
