If you would like to simplify the polynomial (7x^3 - 4x^2 + 5x) - (3x^3 - 11x + 2), you can do this using the following steps:

(7x^3 - 4x^2 + 5x) - (3x^3 - 11x + 2) = 7x^3 - 4x^2 + 5x - 3x^3 + 11x - 2 = 4x^3 - 4x^2 + 16x - 2

The correct result would be 4x^3 - 4x^2 + 16x - 2.

The population of a town is 12,000, and it grows at a rate of 5% per year. Write an exponential function in the form <img src="h

Ksivusya [100]

Answer: Exponential function: $y=12000(1.05)^x$

Step-by-step explanation:

Exponential function: $y=ab^x$ , a = initial value , x= time, b= growth factor , b= 1+r , where r=rate of growth.

Given: Initial population = a= 12,000,

rate of growth = r= 5% = 0.05

Then, b= 1+r= 1+ 0.05 = 1.05

Substitute value of a and b in (i), we get

$y=12000(1.05)^x$

Hence, The required exponential function: $y=12000(1.05)^x$ , where x= time.

The angle between a 180-pound force F and AB= 5i + 2j is 30.Find the work done by F in moving and object from A to B.

Alexeev081 [22]

Answer:

$W=839.464\ ft*lbf$

Step-by-step explanation:

The work done is the product of the magnitude of the force applied to the object by the magnitude of the displacement of the object by the cosine of the angle between the force and direction of the displacement. This is:

$W=|F|*|r|cos(\theta)$
