Answer:
C) Quadrant III
Step-by-step explanation:
Since the total number of available selections is divided by two, the probability is 50%. If we look at the total set of numbers, we find that even numbers are multiples of 2. 2, 4, 6, 8 (which makes up half of the numbers on the spinner).
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: root18
Step-by-step explanation:
A (2,2) x1=2 y1=2
B (5,5) x2=5 y2=5
D(AB) = root [(x2-x1)^2 + (y2-y1)^2]
= root [(5-2)^2 + (5-2)^2]
= root [3^2 + 3^2]
= root (9+9)
D(AB)=root18

Step 1: Simplify both sides of the equation.
−36=p−30
Step 2: Flip the equation.
p−30=−36
Step 3: Add 30 to both sides.
p−30+30=−36+30
p=−6
