18.725 = 18725/1000 = 3745/200 = 749/40 = 18 29/40
so, your answer is 18 29/40
1. No it is not because it is false. It is false because for it to be three times as many wins as jim, jim would need around 166 or less wins to make cy have three times the wins. 2. i believe the graph is misleading because there isnt enough pets on the graph or data on the graph. 3. i honestly dont quite understand the question i would need to see it in person. Hope the first two answers help you out :-)
A parabola is a quadratic function, and a quadratic can be expressed in vertex form, which is:
y=a(x-h)^2+k, where (h,k) is the vertex (absolute maximum or minimum point of the quadratic)
In this case we are given that (h,k) is (-5,80) so we have so far:
y=a(x--5)^2+80
y=a(x+5)^2+80, we are also told that it passes through the point (0,-45) so:
-45=a(0+5)^2+80
-45=25a+80 subtract 80 from both sides
-125=25a divide both sides by 25
-5=a, so now we know the complete vertex form is:
y=-5(x+5)^2+80
The x-intercepts occur when y=0 so:
0=-5(x+5)^2+80 add 5(x+5)^2 to both sides
5(x+5)^2=80 divide both sides by 5
(x+5)^2=16 take the square root of both sides
x+5=±√16 which is
x+5=±4 subtract 5 from both sides
x=-5±4 so the x-intercepts are:
x=-1 and -9
