The C(x) equation is a parabola with a squared "x" and a positive leading term coefficient, meaning, is a vertical parabola and it opens upwards
the lowest point, or lowest cost value, it reaches, is the U-turn point, or vertex
so, the lowest cost is at
The order does not matter, so we will be using combinations here. 52C1 is the first one since there is only one possibility. 16C1 is the second. You have to multiply these two, so 52 X 16 = 832.
Answer:
(1/2,7/4)
Step-by-step explanation:
x=-b/2a
x=1/2
y=(1/2)^2-(1/2)+2
y=1/4-2/4+8/4
y=7/4
Answer:
4.1 calls
Step-by-step explanation:
The number of calls (c) that Roger expects to get as a function of how many inches of snow fall (s), is described by the following linear model:
Therefore, when s = 4.7 inches, the number of service calls that Roger expects is:
Rounding to the nearest tenth, Roger will get about 4.1 calls.
