A=LW
72= 9(2x+4)
72= 18X+36
Sub 36
36= 18X
Divide by 18
X=2

Length (2(2)+4)=8

An airplane 30,000 feet above the ground begins descending at the rate of 2000 feet per minute. Assume the plane continues at th
Aleonysh [2.5K]
If we call y the height of the plane, we know when the time (x) is 0, the height is 30000. So let's write that in:

y = 30000 + (0)

Then, for every increase of a minute (x increases by 1), the height reduces by 2000. This can be written as:

y = 30000 - 2000x

Using what we know about y = mx+c equations, the slope of the line is -2000, and the y-intercept is (0, 30000).

A population of rabbits oscillates 19 above and below average during the year, hitting the lowest value in january. the average
Helen [10]

Answer:

p(t)=650+\frac{160}{12}t+19sin(\omega t)

Step-by-step explanation:

The initial value of the population is 650

Each year the population increases 160

The population oscillates 19 above and below.

Due to this information you can assume that the function is:

p(t)=650+\frac{160}{12}t+19sin(\omega t)

where for t=0 p(t)=650

where t=12 160/12 (12) = 160

you can assume that the sinusoidal function has a period of one month. Thus, the population oscillates several times in one year with an amplitu of the oscillation of 19. The, w is:

\omega (1)=2\pi\\\\\omega=2\pi
