For the function y = 4x⁵, the value of d⁴y/dx⁴ = 320x.
What is a expression? What is a mathematical equation? What is Equation Modelling? What is differentiation?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.

What is the angle of the chord?In geometry, a chord of a circle is a straight line segment whose endpoints both lie on the circle. A diameter of a circle is the longest chord, and it passes through the centre of the circle.
Calculate the value of x as below,
( 13x + 7 - 60 ) / 2 = 5x - 10
13x - 53 = 10x - 20
3x - 53 = -20

What is the application ratio and proportion?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.

If the rotation is clockwise the angle is 120°.
If the rotation is counterclockwise the angle is 240°
The correct options are A and D.
What is the angle of rotation that maps P to G?
We assume that the rotation is clockwise.
First, we can see that the rotation from P to F is just a rotation of 90°.
(point P as at 9 on a clock and point F is at 12 on a clock).
To go from point F to G, we need to move one of the sections defined by the dashed lines, and we know that each one of these measures 30°, then we need to add another 30° to the angle.
90° + 30° = 120°
Then the angle of rotation to map P to G is 120°.
The correct option is D.
Then if the rotation is counterclockwise, the rotation will be of 240°.

competition, the four locations have become less desirable. 3F is considering
eliminating its retail stores in favor of door-to-door selling. It is estimated that
sales would increase by 25% and net profit by birr 30,000. Fixed costs would
increase by birr 30,000 because operations would be moved to a low-rent
warehouse. Required
a) What was the break-even point under the old situation?
b) What will be the break-even point under the proposed situation?
c) What birr sales volume must be obtained under the proposed plan to make as
much profit as last year?
Answers
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.
Define breakeven point.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

In this case, the canister has a radius of 1.56 inches and a height of 6.93 inches,
volume of canister = π × (1.56 inches)² × 6.93 inches
volume of canister = 36.7 in³
To find the volume of a box, we can use the formula V = lwh, where V is the volume, l is the length, w is the width, and h is the height.
In this case, the box has a length of 15.5 cm, a width of 8.6 cm, and a height of 3.8 cm

m/s
Answers
The total distance covered is 15000 m. The total time taken is 5220 seconds and the speed is 2.87 m/s.
What is the speed?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
= 15000 m/5220 second
= 2.87 m/s
