Giving reasons for all the

statements you make, work out

angles DCO, CBO, OCB, and BCD,

all in terms of x.

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.
