Based on its degree, what kind of polynomial is this? h(x)=4x^4+2x-5

To estimate the degree of a polynomial, you just have to take a look at the highest power in the expression. Since here, that is number 4, then it means that this polynomial is a fourth degree polynomial, or quartic polynomial, if you want to sound smart. :)

Consider an economy with two sectors: manufacturing and services. Demand for labor in manufacturing and services are described b

Answer:

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one. Please have a look at the photo

My answers:

a, If workers are free to move between sectors, the wages in each sector will be equal. If wages are not equal, the workers will be motivated to move to sectors with higher wages and this will make a higher salary reduction, and lower wages will increase until they equal.

b. Since there are 100 workers in total,we have:

Ls =100- Lm = 100 -4w

Lm = 4w

Now set this equal to the labor demand for manufacturing equation and solve for w:

4w = 200 - 6w

w = $20.

Substitute w =20 into the two labor demand equations, we have LM = 80 and LS i= 20

c. If the wage in manufacturing is equal to $25 then

Lm=200-6(25) = 50

d. There are now Ls = 50 workers employed in the service sector and the wage:

Ls=100-4Ws

<=> 50 = 100 -4Ws

<=> Ws = 12.5

e. Wages in the manufacturing sector will remain at 25 dollars and jobs will remain at 50. If wages are reserved for the service sector is 15 dollars, then jobs in the service sector will be 40. Therefore 10 unemployed and the unemployment rate is 10%.

Over a 24-hour period, the tide in a harbor can be modeled by one period of a

The sinusoidal function that models the situation is:

$y = 4.5\sin{\left(\frac{\pi}{12}\right)x} + 5$

From the function, we have that:

The amplitude is of 4.5 ft.

The mid-line equation is of y = 5.

<h3>What is a sinusoidal function?</h3>

A sinusoidal function is a trigonometric function, and has the following format, considering no phase shift:

$y = A\sin{(Bx)} + C$

In which:

A is the amplitude, which is the twice the difference between the largest and smallest value.

The period is of $\frac{2\pi}{B}$ .

C is the vertical shift, and the mid-line equation is $y = C$ .

In this problem, the high is of 9.5 ft and the low is of 0.5 ft, hence, for the amplitude, we have that:

$2A = 9$

$A = \frac{9}{2}$

$A = 4.5$

With an amplitude of 4.5, the standard function would vary between -4.5 ft and 4.5 ft, while in this problem the variation is from 0.5 ft to 9.5 ft, hence the vertical shift is of:

$C = 9.5 - 4.5 = 4.5 - (-0.5) = 5$
