A helicopter lowers a rope ladder to a scuba diver floating on the ocean surface. The waves crest at 4ft above the lowest level of the water every 8 seconds. Write a cosine equation to describe the height of the diver as a function of time t. The diver can reach 2ft abover her. The lowest rung of the ladderis 3ft above the average level of the water. For about how many consecutive seconds will the ladder be within the diver's reach

c.35

step-by-step explanation:

8+13=21

21+8=29

29+6=35

equal to

step-by-step explanation:

write out the polynomial, with leading coefficient 1:

y = 1 (x+2)^1 (x-7)^1 (x-5)^2

next time, share the answer choices.   .

if your equation is in the form ax2 + bx + c, you can find the maximum by using the equation:

max = c - (b2 / 4a).

the first step is to determine whether your equation gives a maximum or minimum.

-x2 + 4x - 2.     thats an example hope it
