It would be 365/219 and that equals 1 and 2/3 so ur answer is 1 and 2/3
:)
We know that
the equation of the parabola is of the form
y=ax²+bx+c
in this problem
y=−1/4x²<span>−x+3
where
a=-1/4
b=-1
c=3
</span><span> the coordinates of the focus are
</span>
(-b/2a,(1-D)/4a)
where
D is the discriminant b²-4ac
D=(-1)²-4*(-1/4)*3-----> D=1+3---> D=4
therefore
x coordinate of the focus
-b/2a----> 1/[2*(-1/4)]----> -2
y coordinate of the focus
(1-D)/4a------> (1-4)/(-4/4)---> 3
the coordinates of the focus are
(-2,3)
50 - 6 = 44
44 / 4.50 = 9.77777778 ( 9 sandwich cuz u can get 0.77777778 of a sandwich.)
He can buy 9
Answer:
Option A.
Step-by-step explanation:
we know that
If AB is tangent to the circle
then
The triangle show in the figure must be a right triangle
Remember that
If a triangle is a right triangle, then the triangle must satisfy the Pythagorean Theorem
<u><em>Verify</em></u>
Applying the Pythagorean Theorem


-----> is not true
so
Is not a right triangle
therefore
line AB is not tangent to the circle
