Answer:
The correct answer is C
Step-by-step explanation:
The given circle is centered at A(3, 1) and passes through the origin (0, 0).
The radius of this circle can be found using the distance formula;
.
.
.
.
.
The equation of this circle is given by
Where is the centre.
We substitute the center and radius to obtain;
Option A
When we substitute (2,-2) into this equation we get;
This is true
Option B
When we substitute K(6,0), we get,
This is also true
Option C
We substitute L(4,-4) to get;
This is false. Hence L(4,-4) does not lie on the circle.
Option D
We substitute M(2,4)
This is also true.
The correct answer is C
Answer:
150 ounces
Step-by-step explanation:
H(t) = -16t^2 +704t = -16(t^2 -44t)
Putting in vertex form: -16(t^2 -44t +484) + 704
h(t) = -16(t-22)^2 + 704
It takes 22 seconds to reach the maximum height, which is the vertex of the parabola at (22,704)
Answer:
-1
Step-by-step explanation:
A = (0,0)
B = (1,-1)
Slope = (-1-0)/(1-0) = -1/1 = -1
Answer:
A) 360 adults
Step-by-step explanation:
c=quantity of child
a=quantity of adult
9c+12.5a=5220
a+c=440 then c=440-a
substitute for c
9(440-a)+12.5a=5220
3960-9a+12.5a=5220
reduce
3.5a=1260
a=360
