The graph shows the amount of water that remains in a barrel after it begins to leak. The variable x represents the number of days that have passed since the barrel was filled, and y represents the number of gallons of water that remain in the barrel.

For the function y = 4x⁵, the value of d⁴y/dx⁴ = 320x.

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem. In mathematics, the derivative of a function of a real variable measures the sensitivity to change of the function value with respect to a change in its argument. We can write -

y = f(x)

y' = dy/dx = (d/dx)[f(x)]

We have the following function -

y = 4x⁵

The given function is -

y = 4x⁵

dy/dx = 20x⁴                             {y = xⁿ, then y' = nxⁿ ⁻ ¹}

d²y/dx² = 80x³

d³y/dx³ = 160x²

d⁴y/dx⁴ = 320x

Therefore, for the function y = 4x⁵, the value of d⁴y/dx⁴ = 320x.

The average rate of change is given by -2/5. The correct option is (d).

A ratio is the relation between two numbers as a / b. A proportion is the equality of two ratios as a / b = c / d.

Ratio and proportion can be applied to solve Mathematical problems dealing with unit values of the quantities.

The given graph shows different values of y at x = 4 and x = 14 as follows,

At x = 4, y = 7

And at x = 14, y = 3.

Now, the average rate of change can be determined by taking the ratio of the difference of the values of y to that of x as follows,

(3 - 7)/(14 - 4)

= -4/10

= -2/5

Hence, the average rate of change x = 4 to x = 14 is given as -2/5.

The height of the triangle is 4.68 cm and base of the triangle is 21.36 cm.

A triangle is a geometric figure with three edges, three angles and three vertices. It is a basic figure in geometry.

The sum of the angles of a triangle is always 180°

Given that,

Base of triangle is twelve more than twice its height.

Also, area of triangle = 50 square centimeters.

Let height of the triangle is x cm,

Therefore, the base of triangle will be 2x+12 cm.

The area of triangle = 50

1/2 × (2x+12) × x = 50

x (x+6) = 50

x² + 6x -50 = 0

By solving the equation,

x = -3 + √59 and -3 - √59

Length can not be negative,

Therefore, x = -3 + √59 or x = 4.68114

Height of triangle = 4.68 cm

Base of triangle = 21.36 cm

Answer:[tex]26\frac{7}{12}[/tex]

Step-by-step explanation:

2 1/5 * 12 1/2 = 319/12

319/12 = [tex]26\frac{7}{12}[/tex]

The division between 756 and 26 can be represented as a fraction or decimal as 378/13 or 29.1 respectively

Fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

We can say the fraction of a number is a ratio between the numerator and denominator of two numbers.

Fractions are often as a result of dividing two numbers and they probably don't give a whole number.

In this case, the division between 756 and 26 will result in a fraction because both numbers are not completely divisible by one another.

To divide 756 by 26;

756 ÷ 26 =

Divide both sides by 2

756 ÷ 26 = 378 / 13

Both numbers are not divisible by one another from here, but we can represent this as a fraction of one another;

756 ÷ 26 = 29.076923

The break-even point under the old situation is 680000, the break-even point under the proposed situation is 806451 and the birr sales volume must be obtained under the proposed plan to make as much profit as last year is 1129032.

In economics, business, and particularly cost accounting, the break-even point is the point at which total cost and total income are equal, or "even." Although opportunity costs have been paid and capital has obtained the risk-adjusted, projected return, there is no net loss or gain, and one has "broken even."

In the given question, last year sales=  birr 100000

net profit= 8% of sales

Fixed costs= birr 170000

Estimated sales increase= 25%

Estimated net profit= birr 30000

Increase in fixed cost due to moving to low-rent warehouse= birr 30000

(a) The break-even point under the old situation (X):

   = 100,000 * a - 170,000

   =1,000,000 * 8%

   a= 25% (net profit)

   X*a= 1170,000

   X=680,000

   That is, the break-even point under the old situation is 680000.

(b) The break-even point under the proposed situation is:

      = 1,250,000 x b - 170,000- 30,000

      = 80,000 + 30,000

      b= 24.8%

      X*b=200,00

      X=806451

      The break-even point under the proposed situation is 806451 and

(c) The birr sales volume must be obtained under the proposed plan to make as much profit as last year is:

        X*b -200,000= 80,000

        X*b = 280,00

        X= 1,129,032

The birr sales volume must be obtained under the proposed plan to make as much profit as last year is 1129032.

The other roots of the cubic equation p(x) = 24·x³ - 46·x³ + 29·x - 6 are;

x = 1/2

x = 3/4

A cubic equation is an equation  that has 3 as the highest index.

The specified polynomial in the question is presented as follows;

P(x) = 24·x³ - 46·x² + 29·x - 6

The solution of the equation is; x =  (2/3)

Therefore, (x - 2/3) is a factor of the equation and we get;

(24·x³ - 46·x² + 29·x - 6) ÷ (x - 2/3)  has a remainder of 0

Dividing the above expression using long division, we get;

                    24·x²  - 30·x + 9

                        [tex]{}[/tex]                        9·x - 6

The other real roots of the specified equation can be found as follows;

The equation for the roots is; P(x) = 24·x³ - 46·x² + 29·x - 6 = 0

From the above long division, therefore;

24·x³ - 46·x² + 29·x - 6 = (24·x²  - 30·x + 9) × (x - 2/3) = 0

Which indicates; (24·x² - 30·x + 9) = 0 or (x - 2/3) = 0

The other solution are;

24·x³ - 30·x + 9 = 0

3·(·8·x² - 10·x + 3) = 0

8·x² - 10·x + 3 = 0

Solutions for the above equation in the form; a·x² + b·x + c = 0 can be obtained using the quadratic formula as follows;

The quadratic formula; x = [tex]\dfrac{-b\pm\sqrt{b^2 - 4\cdot a\cdot c} }{2\cdot a}[/tex]

By comparing the equation, 8·x² - 10·x + 3 = 0 to the equation, a·x² + b·x + c = 0, we get;

a = 8, b = -10, and c = 3

Therefore;

x = (10 ± √((-10)² - 4 × 8 × 3))/(2 × 8)

((-10)² - 4 × 8 ×3) = 2

Therefore;

x = (10 ± √((-10)² - 4 × 8 × 3))/(2 × 8) = (10 ± 2)/(16)

x = 3/4, and x = 1/2

Therefore, the other other roots in increasing sequence are;

x = 1/2 and x = 3/4

The total distance covered is 15000 m. The total time taken is 5220 seconds and the speed is 2.87 m/s.

We know that speed has to do with the ratio of the distance that has been covered to the time taken. The speed is a scalar quantity and as such we do not consider the direction hence we would not consider that going back in the opposite direction. The total distance can be obtained algebraically.

The total distance that the student travelled can be obtained from;

5000 m + 5000 m + 5000 m

= 15000 m

The total time taken in seconds = 1800 seconds + 1800 seconds + 1620 seconds

= 5220 second

Speed = Distance/ Time

The profit function is P(x) = −0.5x² + 40x - 100

From the question, we have the following equations that can be used in our computation:

Cost function, C(x) = 50x + 100

Revenue function, R(x) = −0.5(x − 90)² + 4050

The profit function is the difference between the revenue and the cost

So, we have

P(x) = R(x) -CP(x)

Substitute the known values in the above equation, so, we have the following representation

P(x) = −0.5(x − 90)² + 4050 - 50x - 100

Evaluate the like terms

P(x) = −0.5(x − 90)² - 50x   + 3950

Expand

P(x) = −0.5(x² − 180x + 8100) - 50x   + 3950

Expand

P(x) = −0.5x² + 90x - 4050 - 50x   + 3950

Evaluate the like terms

P(x) = −0.5x² + 40x - 100

In (a), we have

P(x) = −0.5x² + 40x - 100

Using a graphing calculator, the reasonable domain is

3 < x < 75

So, the domain is 3 < x < 75

Here, we have

x = 40 or 50

So, we have

P(40) = -0.5(40)² + 40(40) - 100 = 700

P(50) = -0.5(50)² + 40(50) - 100 = 650

In (d), we have

P(40) = 700

P(50) = 650
