As shown below, an observer (o) is located 500 feet from a school (s). the observer notices a bird (b) flying at a 39° angle of elevation from his line of sight. what equation and trigonometric function can be used to solve for the height (h) of the bird? what is the height of the bird? you must show all work and calculations to receive full credit. a right triangle is shown with one leg measuring 500 and another leg measuring h. one angle is marked 39 degrees.

y=mx+b

step-by-step explanation:

m is slope, b is y-intercept

what is the original number? you forgot to add it.

idk man good luck man

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.
