The rates for this problem are given as follows:

1) Between 0 and 2 seconds: 1 meter per second.

2) Between 2 and 4 seconds: 0.5 meters per second.

3) Between 4 and 7 seconds: -1 meter per second.

4) Between 7 and 9 seconds: 0 meters per second.

The rates are not constant.

The average rate of change of a function is given by the change in the output divided by the change in the input. Hence, over an interval [a,b], the rate is given according to the following rule:

[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]

For the first rate, between 0 and 2 seconds, we have that:

Hence:

r = (7 - 5)/(2 - 0) = 2/2 = 1 meter per second.

For the second rate, between 2 and 4 seconds, we have that:

Hence:

r = (8 - 7)/(4 - 2) = 1/2 = 0.5 meters per second.

This rate is already different than the first rate, hence the rates are not constant.

For the third rate, between 4 and 7 seconds, we have that:

Hence:

r = (5 - 8)/(7 - 4) = -3/3 = -1 meter per second.

For the fourth rate, between 7 and 9 seconds, we have that:

Hence:

r = (5 - 5)/(9 - 7) = 0/2 = 0 meters per second.

The surface area of an object is the sum of the areas of all of its faces, or the exterior surfaces of its three dimensions.

Surface area=6(3.4)^2=69.36 square feet

A solid object's surface area is a measurement of the overall space that the object's surface takes up.

The quantity of space enclosing a three-dimensional shape's exterior is its surface area.

A 3D object's surface area is the entire area that all of its faces cover. For instance, if we need to calculate how much paint is required to paint a cube, we can use the cube's surface area. determine how much paint is needed to paint it. It is consistently expressed in square units.

The length of the rectangle is 49 cm.

What is perimeter?

Perimeter is the total distance covered by its boundaries or the sides. Since there are four sides of a rectangle, thus, the perimeter of the rectangle will be the sum of all four sides.

P = sum of all its four sides

P = a + b + a + b   (Opposite sides of rectangle are equal)

P = 2(a + b)

where a is the length and b is the breadth.

According to question, the breadth is 7 cm shorter than length.

Let x be the length and x - 7 be the breadth.

perimeter = 210 cm

2(x+x-7) = 210

2x - 7 = 210/2

2x - 7 = 105

2x = 105 - 7

2x = 98

The second pit stop was 0.327 seconds faster than the first pit stop which is the difference between both time

Subtraction is a mathematical operation that deducts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

We have been given that during a race the first pit stop took 8.352 seconds and the second pit stop took 8.025 seconds.

To determine how much faster the second pit stop.

We need to calculate the difference between the first pit stop and the second pit stop of time.

the difference = Time of first pit stop - Time of second pit stop

the difference = 8.352 - 8.025

Random sampling do not complicates the analysis of cross-sectional data

Sampling is just an action of taking samples or subsets of a given data set for analysis. This means that when sampling is done, the next stage for the samples, are for them to be analyzed.

There different methods of sampling including random sampling. In this type, each member of the samples have equally probability of being chosen.

A cross-sectional data analysis is the analysis of samples or subsets at a fixed point in time. A systematic random sampling method is used in the analysis of cross-sectional data. And when this used, then each combinations of individuals samples in a data set has an equal chance of being selected.

The function is f(x)=(x³+3x²-x-3)/(x²-1)

We have find the continuous function.

If the function's curve DOES NOT break at the point x = a, it is said to be a continuous function at that point in calculus. The mathematical definition of a function's continuity is given below. If x = a, then f(x) is continuous at that moment.

f(a) exists;

The y-intercept of the equation is 4.

The equation of a line is

y = mx + c

x, y is the point on the line

m = slope of a line

c = y-intercept

As the equation of a line is 3x + 2y = 8.

We have to find the y-intercept of the equation.

3x + 2y = 8

2y = -3x + 8

y = -3/2x + 4

y = mx + c

A sequence of transformations that would not return a shape to its original position is: 'Translate 3 unit left, then 3 units down.'

1. Reflect over line x, and over x again.

These transformations are direct opposite and will cancel out one another. Hence, the shape will return to its initial position.

2. Translate 1 unit up, then 4 units down, then 3 units up.

This transformation will return a shape to its original position.

3. Rotate 270° counterclockwise around center C, then rotate 90° counterclockwise around C again.

This means, rotate object by 360° counterclockwise around C.

And this sequence of  transformations will return a shape to its original position.

4. Translate 3 unit left, then 3 units down.

These sequence of transformations would not make a shape go back to its original position.

The value of a, b and c in Y=ax²+bx+c are 3, -5 and 1 respectively.

As it is provided that the quadratic equation Y=ax²+bx+c goes through the coordinates  (-2, 23), (-1, 9), and (4, 29).

One of the method of solving quadratic is by putting the points,

So, it means that these coordinates will satisfy the equation,

So, putting the coordinates in the equation one by one,

First putting (-2,23)

We get,

(23) = a(-2)²+b(-2)+c

23 = 4a-2b+c

Now, putting, (-1,9)

We get,

(9) = a(-1)²+b(-1)+c

9 = a-b+c

From here, we get,

c = 9-a+b.

Now, putting (4,29)

We get,

(29) = a(4)²+b(4)+c

29 = 16a+4b+c

Now, putting c = 9-a+b, in 29 = 16a+4b+c  and 23 = 4a-2b+c,

we get,

29 = 16a+4b+9-a+b

20 = 15a + 5b

dividing by 5,

4 = 3a+b ….. Equation (1)

Now,

c = 9-a+b in 23 = 4a-2b+c,

23 = 4a-2b+9-a+b

14 = 3a-b ….. Equation (2)

Adding equation 1 and 2,

18 = 6a

a = 3,

Putting a = 3 in equation 1,

4 = 3(3)+b

b = -5

We know,

c = 9-a+b

c = 9-3+(-5)

c = 1

So, a = 3, b = -5 and c = 1.
