The height of the ramp if the skateboard has a potential energy of -39.2 kg m² /s² = 2 m

Gravitational acceleration can be defined as the acceleration of any object when the object is in free fall. or we can say that the gravitational acceleration is the quantity which describes the acceleration of free falling object within vacuum. It is denoted by g .

Potential energy is the stored energy of the object which is generally based on the relative position of the various parts of the object. It is also known as gravitational energy.

Formula of potential energy :

U = mgh

where, U = gravitational energy

            m = mass of object

            g = gravitational acceleration

            h = vertical height  of object

In the question given,

g= -9.8m/s² , U = -39.2 kg m² /s²

as, U = mgh

   h = U / mg

  put the values in this equation

  h = -39.2 / 2 (-9.8 )

 h = 2

The complete question is :

On Earth with a gravitational acceleration g , the potential energy stored in an object varies directly with its mass m and its vertical height h .

a. What is an equation that models the potential energy of a 2 -kg skateboard that is sliding down a ramp?

b. The acceleration due to gravity is g=-9.8m/s² . What is the height of the ramp if the skateboard has a potential energy of -39.2 kg m² /s² ?

Answer: (2x-7)(3x+4)

Step-by-step explanation:

There is a technique called the “Slide Method” that can make this easier to solve.

The first step is to slide the coefficient of the 1st term and multiply it to the last term; which becomes:

X^2-13x-28(6) or x^2-13x-168

Next, factor this equation normally. The two factors that go into this are -21 and 8, so we can set this up as: (x-21)(x+8)

After that, divide both sides by the 6 that you previously slid:

(X-21/6)(x+8/6)

Then, reduce the fractions:

(X-7/2)(x+4/3)
After this is the last step. Take the denominator of the fraction, and make it the coefficient of the x variable: (2x-7)(3x+4)

Checking our Work; we get: (6x^2+8x-21x-28)=(6x^2-13x-28)

So, we know that (2x-7)(3x+4) is correct.

If Mr. Jackson has a circular garden with a diameter of 10 feet surrounded by edging and using the same length of edging, he is going to create a square garden, then the maximum side length of the square is equal to 7.85 feet.

First, we have to find the amount of edging Mr. Jackson has. This can be calculated by finding the circumference.

Circumference can be found by using diameter by the formula;

c = π (diameter)

c = π (10)

c = 3.416 feet

This is the amount of edging on the circular garden. As he has to use the same amount of edging on the square garden, the edging on the square garden is the parameter of the square garden. As the parameter of the square is four times the side length, therefore;

3.416 ÷ 4 = 7.85

Hence, the maximum side length of the square is equal to 7.85 feet.

A cost function may be a mathematical formula wont to wont to chart how production expenses will change at different output levels.

From the given information:

It costs Kobel $3.50 in tolls to drive to figure and back day after day, plus he uses 5 gallons of gas. It costs him a complete of $23.50 to drive to figure and back daily.

Then

Total money he spent = Toll cost + amount of gas she used

$23.50 = $3.50 + 5 gallons

Then

Cost of the 5 gallons = 23.50 - 3.50

Cost of the 5 gallons = 20

Then

cost of the 1 gallon gas = 20/5

cost of the 1 gallon gas = $4.

So, The cost spent per gallon of the gas is a $4 and the total money spent on gas is a 20$.

Hans will run additional 9 miles to the 18 miles he has run to complete 27 miles in wants to run for the week.

If Hans is to run 27 miles this week and he has run 18 miles, the additional miles he has to run in the week is t. Meaning that t plus eighteen is equal to 27, which is expressed mathematically below

t + 18 = 27

To solve the equation above, use balancing method. To use balancing method, subtract 18 from both side of the equation.

t +18 -18 = 27-18

t + 0 = 27-8

t = 27 -18

t = 9

Therefore, Hans will run additional 9 miles to complete 27 miles for the week.
