Which of the following linear models predicts the population, y, of Florida (in millions) in terms of x, the number of years since 2020. A. y = 17.4x + 0.22

B. y = -0.22x + 17.4

C. y = 0.22x + 17.4

D. y = -17.4x + 0.22

13

step-by-step explanation:

distance formula is d=√(x2-x1)^2   +   (y2-y1)^2

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
