PLEASE HELP. I’ll mark you as brainliest if correct!

Robyn spent two months traveling in Country A. The day she arrived, the exchange rate was 1.3 Country A dollars per Country B dollar. Complete parts (a) and (b).
(a) If she exchanged 100 Country B dollars when she arrived, how many Country A dollars did she receive?

What is the difference between the predicted value and the actual value

The diagram represents the polynomial 4x2 + 23x – 72. what is the factored form of 4x2 + 23x – 72? (4x + 8)(x – 9) (4x – 8)(x + 9) (4x + 9)(x – 8) (4x – 9)(x + 8)

Is there a direction u in which the rate of change of f(x,y)equals=x squared minus 3 xy plus 4 y squaredx2−3xy+4y2 at p(1,2) equals 14? give reasons for your answer. choose the correct answer below. a. no. the given rate of change is smaller than the minimum rate of change. b. no. the given rate of change is larger than the maximum rate of change. c. yes. the given rate of change is larger than the minimum rate of change and smaller than the maximum rate of change.
