In the interval [0, π/2], the function is one-to-one or injective.

The functions which have one-to-one behaviour are called injective functions. An injective function is a function in which every horizontal line in the plane intersects the graph of f at most one point or we can say if f(x) = f(y) then x = y.

First, we need to draw the graph of y = |cos x|. The graph of y = |cos x| is attached.

We can see from the graph that the value of the function is 1 when x = 0 and the value of the function decreases till it takes 0 at x = π/2 and then the value of the function increases again.

In the option [0, π] and [0, 2π] the behaviour of the function is not injective.

In [0, π/4], the function is injective but [0, π/2] is the correct answer as it represents the largest interval starting from 0 on which this function is one-to-one.

An integral which is not having any upper and lower limit is known as an indefinite integral. Mathematically, if F(x) is any anti-derivative of f(x) then the most general antiderivative of f(x) is called an indefinite integral and denoted, ∫f(x) dx = F(x) + C.

Identify The Parent Function.

Reflect Over X-Axis or Y-Axis.

Shift (Translate) Vertically or Horizontally.

Vertical and Horizontal Stretches/Compressions.

Plug in a couple of your coordinates into the parent function to double check your work.

Transformation of functions means that the curve representing the graph either "moves to left/right/up/down" or "it expands or compresses" or "it reflects". For example, the graph of the function f(x) = x2 + 3 is obtained by just moving the graph of g(x) = x2 by 3 units up.

There are different formulas for different rules of transformation. For vertically transformation the function f(x) is transformed to f(x) + a or f(x) - a. For horizontal transformation the function f(x) is transformed to f(x + a) or f(x - a). Further for stretched or compressed transformation is it f(cx) or cf(x).

Let's start by converting this word problem into math equations... This will make it much easier to choose an approach to the problem!

Write equations for both Dave and Angie. We will use the variables P for slices of pizza, and W for bottles of water bought.  

(1) Dave: [tex]3P+2B=12.75[/tex]

(2) Angie: [tex]1P+3B=7.75[/tex]

Now that we have these equations, it's much easier to tell that this is a system of two equations (two equations, two unknowns). To solve this system, we can use a variety of different methods. For this problem, let's use the Elimination method (removing one variable from the equation.

Start by multiplying (scaling) Angie's equation by a factor of -3, so that we will be able to remove Pizza slices from the equation:

(3) [tex]-3(1P+3B=7.75) \equiv -3P-9B=-23.25[/tex]

Now, let's add Angie's new equation to Dave's original:

[tex]-7B=-10.5[/tex]

Notice that we now only have one variable in this simple equation. This is very easy to solve!

Simplify:

[tex]B=1.5[/tex]

Now that we have the price for a bottle of water, we can substitute this value into either (1) Dave's or (2) Angie's original equation to find the price for a slice of Pizza (P). I will substitute into (1) Dave's equation:

Substitute:

[tex]3P+2(1.5)=12.75[/tex]

Simplify:

[tex]3P=9.75[/tex]

Divide:

[tex]P=3.25[/tex]

Finally, we have reached our conclusion... A slice of Pizza costs $3.25 and a bottle of water costs $1.5 at the concession stand! Let me know if you have any questions or want to learn other ways of solving this problem!

(15.40)(20) = $308

The total cost of the six fill-ups during winter is $4977.

Word problems are mathematical problems expressed with words that involve the interpretation of mathematical variables and the usage of the appropriate arithmetic operations to solve them.

From the given information;

If the price per gallon is $3.95 and a tank can hold 210 gallons. Then, the price for a single full tank is $3.95 × 210 = $829.5

In addition to that, if Tanis has six fill-ups tanks during the winter, his total cost would be:

= $829.5 × 6

= $4977

Therefore, we can conclude that the total cost of the six fill-ups during winter is $4977.

A second-degree polynomial can be used to fit the three data points by finding the coefficients of the polynomial that pass through the three given points. The general form of a second-degree polynomial is:

p(x) = ax^2 + bx + c

We can use the three data points to solve for the coefficients a, b, and c. Let's use the year 2000 as the reference point and set x = 0. Then, we have:

p(0) = c = 287 million (at x = 0, the population is 287 million)

Next, let's use the data point for 1990, which is 244 million. The year 1990 is 10 years before 2000, so x = -10. Substituting these values into the polynomial, we have:

p(-10) = a * (-10)^2 + b * (-10) + c = 244 million

Solving for a and b using the two equations above, we have:

a = (244 - 287 + 10b) / 100

c = 287

Substituting these values back into the polynomial, we have:

p(x) = (244 - 287 + 10b) / 100 * x^2 + bx + 287

Finally, let's use the data point for 2010, which is 324 million. The year 2010 is 10 years after 2000, so x = 10. Substituting these values into the polynomial, we have:

p(10) = (244 - 287 + 10b) / 100 * 10^2 + b * 10 + 287 = 324 million

Solving for b, we have:

b = (324 - 244 + 287) / 10 - (244 - 287) / 100 * 10^2 = 37

Therefore, the final form of the second-degree polynomial that passes through the three data points is:

p(x) = (244 - 287 + 10 * 37) / 100 * x^2 + 37x + 287 = 7x^2 + 37x + 287

This polynomial can be used to estimate the population of the country for any year close to 1990, 2000, or 2010.

Using the definition of the derivative, the derivative of the function is f'(t) = 5t + 6. The domain of the function and its derivative are both the set of all real numbers.

The derivative is a concept in calculus that represents the rate of change or the slope of a function at a specific point. It is defined as the limit of the difference quotient of the function as the interval between the two points approaches zero. Mathematically, the derivative of a function f(x) at a point x is represented as f'(x) and can be expressed as:

f'(x) = lim h -> 0 [f(x + h) - f(x)]/h

where h is the interval between the two points.

The derivative is a fundamental tool for analyzing and understanding the behavior of functions, including their local maxima, minima, and inflection points, as well as for solving problems in physics and engineering.

The derivative of the function f(t) = 2.5t² + 6t can be found using the definition of the derivative:

f'(t) = limit as h -> 0 of [f(t + h) - f(t)]/h

= limit as h -> 0 of [2.5(t + h)² + 6(t + h) - (2.5t² + 6t)]/h

= limit as h -> 0 of [2.5t² + 5ht + 2.5h² + 6t + 6h - 2.5t² - 6t]/h

= limit as h -> 0 of [5ht + 2.5h² + 6h]/h

= limit as h -> 0 of [5t + 2.5h + 6]

= 5t + 6

The domain of the function f(t) = 2.5t^2 + 6t is all real numbers. The domain of its derivative f'(t) = 5t + 6 is also all real numbers.

The volume of a rectangular prism is given by the product of its length, width, and height.

We know that the volume is 48x^8, so we can write an equation:

48x^8 = (4x^2)(6x^3)(h)

We can simplify the left side:

48x^8 = 24x^5 * h

And divide both sides by 24x^5 to find the height:

h = 48x^8 / 24x^5 = 2x^3

The distance between the two points is 13 units.

Distance between two points is the length of the line segment that connects the two points in a plane.

The formula to find the distance between the two points is usually given by d=√((x2 – x1)² + (y2 – y1)²)

point 1 (1, 4): x1 = 1 , y1 = 4

point 2 (6, 16): x2 = 6 , y2 = 16

Using the formula with the given values:

d=√((x2 – x1)² + (y2 – y1)²

d=√((6 – 1)² + (16 – 4)²)

d=√(5² + 12²)

d = √169
