The number of internet users in the United States(in millions), y, at x years since 1995 is given by y = 19.7917 + 20.7167xa) Use the equation to predict the number of internet users in 1995 (x=0), 1997 (x=2) and2005 (x=10). Round to the nearest tenth of a million .b)Use part (a) to graph the line.

19.8 ; 61.2 ; 227.0

Step-by-step explanation:

Given the regression model :

y = 19.7917 + 20.7167x

Number of internet users in 1995, x = 0

Put x = 0 in the equation :

y = 19.7917 + 20.7167(0)

y = 19.7917 + 0

y = 19.7917

y = 19.8

b.)

1997, x = 2

Put x = 2

y = 19.7917 + 20.7167(2)

y = 61.2251

y = 61.2

c.)

2005, x = 10

y = 19.7917 + 20.7167(10)

y = 226.9587

y = 227.0

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
