researchers surveyed a populations of gentoo penguins on an island in the antarctic during breeding season from 1980-2000. The population was comprised of 390 breeding pair in 1980 and increased by about 4.4 percent per year through 2000.

407.16

Step-by-step explanation:

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°
