Answer:

(a) 129600 J

(b) 81000 J

Step-by-step explanation:

The work done is given by the product of force and the displacement in the direction of force.

Force, F = 500 N

distance, d = 324 m

(a) friction force, f = 100 N

The work done is

W = (F - f) x d

W = (500 - 100) x 324

W = 129600 J

(b) Friction, f = 250 N

The work done is

W = (F - f) d

W = (500 - 250) x 324

W = 81000 J

Equation:  2/5 + p = 4/5 + 3/5p

Simplify Both Sides:
p + 2/5 = 3/5p + 4/5

Subtract 3/5p from both sides:
p + 2/5 - 3/5p = 3/5p + 4/5 - 3/5p

2/5p + 2/5 = 4/5

Subtract 2/5 from both sides:
2/5p + 2/5 - 2/5 = 4/5 - 2/5

2/5p = 2/5

Multiply both sides by 5/2

(5/2) * (2/5p) = (5/2) * (2/5)

p  =  1


Answer:  p  =  1





Hope that helps!!! (Answer:   Letter Choice (A),  p  =  1

Which algebraic expression is a polynomial? Which term could be put in the blank to create a fully simplified polynomial written
kifflom [539]

Answer:

x^3y and  x^2y^2

Step-by-step explanation:

An algebraic expression is a polynomial if and only if the variables involve have positive integral indices or exponents.

The given polynomial is: 8x^3y^2----------+3xy^2

We want to put one of the following polynomials in the blank space to create a fully simplified polynomial written in standard form.

-4y^3

x^2y^2

x^3y

7x^2y

7x^0y^3

A fully simplified polynomial written in standard form is obtained by writing the simplified polynomial in decreasing order according to degree.

Since the first term of  8x^3y^2----------+3xy^2 having a degree of 5 and the last term is having a degree of 3.

The polynomial that goes into the blank must have a degree of 4.

This eliminates -4y^3, 7x^2y

and 7x^0y^3

We are now left with x^2y^2 and x^3y

The required polynomial is therefore 8x^3y^2-x^2y^2+3xy^2 or8x^3y^2-x^3y+3xy^2

These two polynomials are in standard form and cannot be simplified further.

The correct choices are;

x^3y and  x^2y^2

Points C and D lie on graph of the equation y = 1.3x.
deff fn [24]
Y = 1.3x

point C : (3,?)...so we sub in 3 for x and solve for y
y = 1.3(3)
y = 3.9
so point C is (3,3.9)

point D : (-6,?)...so we sub in -6 for x and solve for y
y = 1.3(-6)
y = -7.8
so point D is (-6,-7.8)
