If you stand next to a wall on a frictionless skateboard and push the wall with a force of 36 N, how hard does the wall push on

VARVARA [1.3K]

The wall pushes back with an equal and opposite force. So it pushes with a force of 36N in the opposite direction of the push. This allows you to move away from the wall.

Answer:

Part I: The degree of a polynomial is the greatest of the degrees of its terms.

Part II: In order to write a polynomial in descending order, you must write the terms with the exponents decreasing from left to right.

Part III: A. -4x² + 11x - 12, degree = 2,

B. 5x³ + 4x + 14, degree = 3.

Step-by-step explanation:

Part I : Since the degree of a polynomial is the highest power of its monomials ( single term ),

e: degree of is 5.

Thus, in part I, the correct option is 'greatest'

Part II: When we write a polynomial then we write the terms of the polynomial in descending order of their degrees.

Thus, in part II the correct option is 'least'

Part III: A.

∵ -4x² has the highest power in the polynomial.

⇒ Degree = 2,

Also, in the polynomial descending order of degrees,

2 > 1 > 0

⇒ polynomial in descending order,

Combining like terms,

∵ 5x³ has the highest degree,

⇒ Degree = 3,

Also, the order of the degrees in the polynomial is,

3 < 2 < 1 < 0

Thus, the polynomial in descending order,

Seth has just decided to replace his computer. His old computer cost him $1,433 when he bought it exactly seven years ago. Seth

Answer:

The answer is D

Step-by-step explanation:

The solution would be like this for this specific problem:

Cost of the computer:

i = 0.117 / 12

i = 0.00975

= monthly payment

= (i * P * (1 + i)^n) / ((1 + i)^n - 1)

= (0.00975 * $1433 * (1 + 0.00975)^30) / ((1 + 0.00975)^30 - 1)

= $55.32

Electricity cost:

= $0.79 * 365.25 * 7

= $2019.83

Electricity Percentage:

= $2019.83 / ($2019.83 + $1659.60)

= 54.89%

Electricity:

= ($0.79 * 365 * 5) + ($0.79 * 366 * 2)

= $2020.03

Electricity Percentage:

= $2020.03 / ($2020.03 + $1659.60)

= 54.898%

In total, the electricity made up 54.898% of the lifetime cost of the computer.
