Two forest rangers leave base and travel to different parts of the forest.

simone averages 70 km/hr along a straight track in a direction 25°, while bruce averages 80 km/hr in a direction 135°. after 1.5 hours they stop and make radio contact.

a) how far have they each travelled?

b) how far apart are they?

c) simone travels directly to join up with bruce. what bearing should she follow?

step-by-step explanation:

6 spoons of sugar for every 21 cups of flour

step-by-step explanation:

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
