For 1970 through 1990, the amount A (in millions of dollars), spent on automotive advertising in the United
States can be modeled by A=0.52(t) ? + 90 where
t=0 represents 1970.
In what year was
approximately $471 million spent on automotive
advertising?A
A:1986
B:1984
C:1980
D:1982

the right system of equations to describe the situation would

be on the form:

x1 = 8000 + y1*t

and

x2 = 8000 + y2*t

where x1 and x2 represents the total money of imogene and her

friend respectively at the end of t years.

now for the value of amount earned, y1 and y2:

y1=8000*0.08

y2=2000*√(t-2)

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.

are ya tryin to ask something or is this a statement

add the numbers under frequency to find the total number:

5 + 8 +7 + 4 + 0 +1 = 25

the answer is 25.
