Speed is 0.01 miles per minute.

we know speed is = distance/ time

since we need speed in miles per minute we need to convert km into miles.

and hours in minute.

distance= 5km

1km= 0.621371 miles

5km= 50.621371 miles = 3.10686 miles= 3.12 miles

1hour= 60 minutes

4.5 hour = 4.5×60 minutes=270 minutes

speed= distance in km/time in minutes=3.12 miles/270 minutes

speed = 0.012 miles per minute

speed is 0.01 miles per second.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

The equation in slope-intercept form is given as,

y = mx + c

Where m is the slope and c is the y-intercept.

The equation for y is y = 2x - 2/3

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 = 4 is an equation.

2x = 4x is an equation

We have,

3y - 6x = -2

Add 6x on both sides.

3y = -2 + 6x

3y = 6x - 2

Divide both sides by 3.

y = (6x - 2)/3

y = 2x - 2/3

This is in the form of an equation in slope-intercept form.

Using a linear function and the work integral, it is found that the work that was done lifting the sand this far is of 944 ft-lb.

A linear function is modeled by the following rule:

y = mx + b

In which:

For the weight of the bag of sand in this problem, we have that:

Hence the weight of the bag after being lifted x feet is given by:

W(x) = 144 - 4x.

The work realized for a function f(x) in an interval [a,b] is given by the following integral:

[tex]W = \int_{a}^{b} f(x) dx[/tex]

For this problem, the function and the bounds of the interval are given as follows:

Hence the work is given by:

[tex]W = \int_{a}^{b} (144 - 4x) dx[/tex]

W = 144x - 2x², from x = 0 to x = 18.

Applying the Fundamental Theorem of Calculus:

W = 144(18) - 2(18)² - 144(0) + 2(0)² = 1944 ft-lb.

The work that was done lifting the sand this far is of 944 ft-lb.

Given function y =45(0.974)ˣ is a function of exponential decay and percentage rate of decrease is 2.6%.

The exponential function is an function f(x) = a(b)ˣ

a = initial amount when x= 0

b= base that is multiplied and it is greater than 0

And x is the variable in the exponent

When b> 1 , the values of this function goes up and up and then this function shows exponential growth.

When 0< b< 1, the values of this function becomes smaller as x increases then this function shows exponential decay.

And r is the percentage rate of change where b =r +1

Given function is y = f(x) = 45(0.974)ˣ

When we compare it with standard function f(x) = a(b)ˣ

we get a = 45 and b =0.974

As b is between 0 and 1 in this case, therefore this function is exponential decay.

b =r+ 1

therefore r = b-1 = 0.974-1 = -0.026

converting 0.026 to percentage we get -0.026*100= -2.6% ( negative sign shows decrease)

Therefore, we can say that the given function represents exponential decay function and rate of decrease is 2.6%

The number of kilometers represented by 8cm is 80km.

According tot he question we have been the proportion of scaling on the map which is as follows:

                             1 cm : 10 km   or it is also written as   1cm/10km

We need to find the number of kilometers represented by 8 cm

Let the number of kilometers that we need to find be x km. Mathematically the proportion can be written as

                              8 cm : x km     or it is written as    8cm / x km

Also both the proportion will be equivalent. Therefore, the proportion is equal to

                              1/10 = 8/x

we will solve this for x, we get

                                x = 8*10

It is given that the sum is greater than 4 and smaller than 10.

If the sum is less than 10 and greater than 4 that limits you to 5,6,7,8,9

It should be noted that 5+5 is 10, and the sum has to be lower then 10.

The addends are less than 5 so it could be 4+4, 4+3, 4+2, 4+1

The values of t for which the ball's height is 16 feet are 1.84s and 0.41s

From the question, we are to determine all values of t for which the ball's height is 16 feet

From the given information,

The equation that represents the ball's height (in feet) after t second is

h = 4 + 36t - 16t²

To determine all values of t for which the balls height is 16 feet, we will put h = 16 in the equation

That is,

h = 4 + 36t - 16t² becomes

16 = 4 + 36t - 16t²

Rearranging

16t² - 36t + 16 - 4 = 0

16t² - 36t + 12 = 0

Divide through by 4

4t² - 9t + 3 = 0

Solve the quadratic equation using the general formula

t = [-b±√(b²-4ac)]/2a

a = 4, b = -9, c = 3

t = [-(-9)±√((-9)²- 4(4)(3))]/2(4)

t = [9±√(81- 48)]/8

t = [9±√(33)]/8

t = [9±5.74]/8

t = [9+5.74]/8 or  [9-5.74]/8

t = 14.74/8 or  3.26/8

t = 1.84 or 0.41

Hence, the values of t for which the ball's height is 16 feet are 1.84s and 0.41s

The solution by using the quadratic formula is,

What is Quadratic formula?

To solve a quadratic equation ax²+ bx + c = 0 , we use the quadratic formula,

x = - b ± √b² - 4ac / 2a

The given expression is;

- 2x² + 4x = 5

Now, The given equation is solve by using Quadratic formula as;

- 2x² + 4x = 5

Move terms to the left side

- 2x² + 4x - 5 = 0

- ( 2x² - 4x + 5 ) = 0

2x² - 4x + 5 = 0

Compare with quadratic equation ax²+ bx + c = 0 we get;

a = 2, b = -4, c = 5

Since, Quadratic formula is,

x = - b ± √b² - 4ac / 2a

Hence, Substituting all the values of a, b and c in quadratic formula we get;

x = - (-4) ± √(-4)² - 4*2*5 / 2*2

x = 4 ± √16 - 40 / 4

x = 4 ± √-24 / 4

x = 4 ± 2√-6 / 4             ( Since, i = √-1  )

x = 4 + 2√6 i / 4   and x = 4 - 2√6 i / 4
