Answer:
135
Step-by-step explanation:
angle APB is an alternate interior angle to DBC and line DB is supplementary
APD=180-45=135
We know that
the equation of the parabola is of the form
y=ax²+bx+c
in this problem
y=1/4x²−x+3
where
a=1/4
b=-1
c=3
the coordinates of the focus are
(-b/2a,(1-D)/4a)
where D is the discriminant b²-4ac
D=(-1)²-4*(1/4)*3-----> D=1-3---> D=-2
therefore
x coordinate of the focus
-b/2a----> 1/[2*(-1/4)]----> 2
y coordinate of the focus
(1-D)/4a------> (1+2)/(4/4)---> 3
the coordinates of the focus are (2,3)
Answer:
0.06 Cent
Step-by-step explanation:
Per Pound= Every one
so 1.20 divided by 20
= 0.06
So the price per pound of beans is 0.06 Cent
D! I’ve taken this
Please mark me as brainliest!
Your not being very discriptive... BUT if you are finding 'x'...
(14x-35)/17=7
*17 *17
14x-35=119
+35 +35
14x=154
/14 /14
x=11
