The number N (in thousands) of existing condominiums and cooperative homes sold each year from 2000 through 2008 in the United States is approximated by the model N=0.4825t4−11.293t3+65.26t2−48.8t+5 78 0≤t≤8 where t represents the year, with t=0 corresponding to

The number of condominiums ranges between 578 thousand to 639.544 thousand between the years 2000 to 2008

Step-by-step explanation:

N=0.4825t4−11.293t3+65.26t2−48.8t+578

Putting t =0

N=0.4825(0)^4−11.293(0)^3+65.26(0)^2−48.8(0)+578

N= 578

Putting t =8

N=0.4825(8)^4−11.293(8)^3+65.26(8)^2−48.8(8)+578

N= 1976.32 - 5782.016+4176.64-390.4 +578

N= 639.544

The minimum number of condominiums sold are 578 thousand .

And the maximum number of condominiums sold are 639.544 thousand.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
