if the second derivative is negative, then the first derivative is decreasing, Graphically, we see this as the curve. of the graph being concave down, that is, shaped like a parabola open downward.

The second derivative tells whether the curve is concave up or concave down at that point. If the second derivative is positive at a point, the graph is bending upwards at that point. Similarly if the second derivative is negative, the graph is concave down.

When second derivative is positive concavity?

If the second derivative is positive at a point, the graph is concave up at that point. If the second derivative is positive at a critical point, then the critical point is a local minimum. If the second derivative is negative at a point, the graph is concave down.

Taxes can be paid in cash or labor and can be either direct or indirect.

Cost of juice bottle is $27.54.

Tax compliance refers to policy actions and individual behavior aimed at ensuring that taxpayers are paying the right amount of tax at the right time and securing the correct tax allowances and tax reliefs. A tax is a mandatory financial charge or some other type of the levy imposed on a taxpayer (an individual or legal entity) by a governmental organization in order to fund government spending and the various public expenditures (regional, local, or national). Around 3000–2800 BC, the first recorded taxation was enacted in ancient Egypt. Non-compliance with the law includes failing to pay on time as well as evading or resisting taxation. Taxes can be paid in cash or labor and can be either direct or indirect.

Most nations have a tax system in place to finance public, shared, or agreed-upon national necessities as well as governmental duties. While some scale taxes are progressive based on brackets of annual income amounts, most impose a flat percentage rate of taxation on personal annual income. The majority of nations impose taxes on both personal and business income. The Wealth taxes, inheritance taxes, estate taxes, gift taxes, property taxes, sales taxes, usage taxes, payroll taxes, fees, and/or tariffs are frequently levied by nations or subunits.

Since the points on this graph represent a relationship between x- and y-values, the statement which is true about the relationship is that: 4. It cannot be proportional because a straight line through the points does not go through the origin.

A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.

In Mathematics, the graph of any proportional relationship is characterized by a straight line with the points passing through the origin (0, 0) because as the values on the x-axis (x-coordinate) increases or decreases, the values on the y-axis (y-coordinate) increases or decreases simultaneously.

In this context, we can reasonably infer and logically deduce that the relationship between x-values and y-values in this graph is not proportional.

The range of sales for the given condition is (25000, +∞), Hence Mrs. Dundee makes more from the second publisher than the first.

As per the question statement, Mrs. Dundee wants to sell the rights to her Cajun cookbook so one publisher offered to pay $80,000 and a $3 royalty for every book sold and publisher two offered to pay $30,000 and $5 for every book sold.

We are supposed to find the range of sales for the given conditions.

Let's suppose Mrs. Dundee sold "x" books

30,000 + 5x > 80,000 + 3x

2x > 50,000

x > 25,000

So, the range of sales for the given condition is (25000, +∞), Hence Mrs. Dundee makes more from the second publisher than the first.

The component form of the resulting vector is <5, -4>

Vector:

Vector means the objects which have both, magnitude and direction. Magnitude defines the size of the vector. It is represented by a line with an arrow, where the length of the line is the magnitude of the vector and the arrow shows the direction.

Given,

Vector v = <3, 1>.

Here we need to find the value of u through the given graph and we have to perform the addition operation in order to find the component form of the resulting vector.

Here we have the value of vector v = <3,1>

While observing the graph we have identified as the value of vector u is,

x value = 2

y value = -5

So, the component from of vector u = <2, -5>

Now the addition of u + v is equal to,

=> u + v

=> <3,1> + <2, -5>

=> < (3 + 2) , (1 + (-5))>

=> < 5, -4>

Answer:

Draw vector v in standard position. To add v to u, shift v 2 units to the right and 5 units down so its initial point coincides with the terminal point of u. Use a dotted line to depict the shifted vector v.

Now there are three sides of a parallelogram. To complete the parallelogram, draw a dotted line from the tip of vector v in the standard position to the tip of the shifted vector v.

Finally, draw the vector represented by the diagonal of the parallelogram with its initial point at the origin. The resultant vector, u + v, is this diagonal of the parallelogram in which the two vectors, u and v, are adjacent sides. The components of u + v are <5, -4>.

The cost of 18 slices of pizza is $18.

The monthly cost for x slices of pizza is $25 + x

The equation that represents the amount of money that Ava would have to pay when she buys 18 slices of pizza is a linear equation. A linear equation is an equation that has one variable raised to the power of one. The linear equation increases by a fixed amount. When drawn on a coordinate plane, a linear equation is a straight line.

The total monthly cost is a function of the membership fee, the cost per pizza and the number of pizzas bought.

The form of the linear equation is :

fx = mx + b

Total amount paid = membership fee + total cost of pizzas

Total amount paid for 18 pizzas = cost per pizza x number of pizzas bought

$18 x 1 = $18

Total monthly cost for x pizzas = membership fee + (discounted price x number of pizzas bought)

1) The slope of line that goes through the points (12, 13) and (-8, 8) is; 5/28

2) Using the point (12, 13) and the slope 5/28, the equation of the line is;

y - 13 = (5/28)(x - 12)

3) The equation of the line in slope intercept form is;  y =  (5/28)x - 76/7

We are told that a line goes through the points; (12, 13) and (-8, 8)

1) The slope is gotten from the formula;

m = (y2 - y1)/(x2 - x1)

m = (8 - 13)/(-8 - 20)

m = -5/-28

m = 5/28

2) Using the point (12, 13) and the slope 5/28, the equation of the line is;

y - 13 = (5/28)(x - 12)

3) Expanding the equation in answer 2 above, we have;

y - 13 = (5/28)x - (60/28)

y - 13 = (5/28)x - 15/7

320 Tiles of measuring 20cm*50cm will be needed to cover a wall 4m by 8m.

Let to cover the wall of dimension 4m * 8m completely with the tiles we need x number of tiles of size 20cm * 50 cm.
The area of wall must be that of total areas covered by tiles.

So,

Area of 1 Tile = 20cm * 50 cm = 1000sq. cm

Total Area of Tiles needed = 1000x sq.cm

Total Area of wall = 4m * 8m = 400 * 800 = 320000 sq. cm

So, We know that

Total Area of wall = Area of 1 Tile * x

320000 = 1000x
