STEP 1:
Find % of gold members. Subtract the known % of bronze and silver members from 100%.
x= percent of gold members
x= 100% - (40% +28%)
x= 100% - 68%
x= 32% percent of gold members
STEP 2:
Find number of gold members. Multiply % of gold members by the total numbers of members (275).
x= # of gold members
x= 275 * 32%
x= 275 * 0.32
x= 88 gold members
Hope this helps! :)
2 I think that is the answer
Chris has most the. Alex follows jaden has the least amount ( no model shown so cant answer on that)
Answer:
The equation of the quadratic graph is f(x)= - (1/8) (x-3)^2 + 3 (second option)
Step-by-step explanation:
Focus: F=(3,1)=(xf, yf)→xf=3, yf=1
Directrix: y=5 (horizontal line), then the axis of the parabola is vertical, and the equation has the form:
f(x)=[1 / (4p)] (x-h)^2+k
where Vertex: V=(h,k)
The directix y=5 must intercept the axis of the parabola at the point (3,5), and the vertex is the midpoint between this point and the focus:
Vertex is the midpoint between (3,5) and (3,1):
h=(3+3)/2→h=6/2→h=3
k=(5+1)/2→k=6/2→k=3
Vertex: V=(h,k)→V=(3,3)
p=yf-k→p=1-3→p=-2
Replacing the values in the equation:
f(x)= [ 1 / (4(-2)) ] (x-3)^2 + 3
f(x)=[ 1 / (-8) ] (x-3)^2 + 3
f(x)= - (1/8) (x-3)^2 + 3
