From the graph of miles driven and pricing, it can be observed that for 200 miles option A price is $100 and option B price is $70.

So option A cost more than option B.

Determine the difference between $100 and $70 to obtain how much option A cost more than option B.

So option A cost $30 more than option B.

From the graph, it can be observed that lines of option A and option B intersect each other at (50,40). So option A and option B cost same for 50 miles.

Approximately 68% of bottles have fill volumes within 1 ml of the mean. This is because in a normal distribution, about 68% of the data falls within one standard deviation of the mean, and the standard deviation in this case is 4 ml. So, within 1 ml of the mean, we can expect a similar proportion of bottles.

In a normal distribution, the data is symmetrically distributed around the mean. The standard deviation tells us the average amount of variation from the mean. In this case, the standard deviation is 4 ml, which means that about 68% of the data falls within one standard deviation of the mean, both above and below it. Since we're interested in bottles with fill volumes within 1 ml of the mean, which is a range of two standard deviations, we can expect a similar proportion of bottles, approximately 68%, to fall within that range.

The probability of drawing a red ball on the first draw is 3/5. Since the ball is not replaced, there are now 4 balls left in the bag, with 2 blue balls. Thus, the probability of drawing a blue ball on the second draw is 2/4 or 1/2. Therefore, the probability of drawing a red ball on the first draw and a blue ball on the second draw is (3/5) * (1/2) = 3/10.

To calculate the probability of drawing a red ball on the first draw and a blue ball on the second draw, we use the multiplication rule of probability. According to this rule, the probability of two events A and B occurring is the product of the probabilities of each individual event.

Here, event A is drawing a red ball on the first draw, which has a probability of 3/5 since there are 3 red balls out of 5 total balls in the bag. Since the ball is not replaced after the first draw, event B is drawing a blue ball on the second draw from the remaining 4 balls. There are 2 blue balls out of 4 total balls left in the bag, so the probability of drawing a blue ball on the second draw given that a red ball was drawn on the first draw is 2/4 or 1/2.

Thus, the probability of drawing a red ball on the first draw and a blue ball on the second draw is (3/5) * (1/2) = 3/10. Therefore, the probability of drawing a red ball on the first draw and a blue ball on the second draw is 3/10.

The derivative of f(x) = sech^(-1)(x^2) is f'(x) = 2x/sqrt(1 - x^4).

a) To find f'(x) for f(x) = x*sin(x), we can use the product rule and the derivative of the sine function.

Using the product rule, we have:

f'(x) = (xsin(x))' = xsin'(x) + sin(x)*x'

The derivative of sin(x) is cos(x), and the derivative of x with respect to x is 1. Therefore:

f'(x) = x*cos(x) + sin(x)

So, the derivative of f(x) = xsin(x) is f'(x) = xcos(x) + sin(x).

(b) To find f'(x) for f(x) = sech^(-1)(x^2), we can use the chain rule and the derivative of the inverse hyperbolic secant function.

Let u = x^2. Then, f(x) can be rewritten as f(u) = sech^(-1)(u).

Using the chain rule, we have:

f'(x) = f'(u) * u'

The derivative of sech^(-1)(u) can be found using the derivative of the inverse hyperbolic secant function:

(sech^(-1)(u))' = 1/sqrt(1 - u^2)

Since u = x^2, we have:

f'(x) = 1/sqrt(1 - (x^2)^2) * (x^2)'

Simplifying:

f'(x) = 1/sqrt(1 - x^4) * 2x

So, the derivative of f(x) = sech^(-1)(x^2) is f'(x) = 2x/sqrt(1 - x^4).

"y" will represent the total cost per month

"x" will represent the number of movies watched in one month

There are two streaming plans:

Plan A

Has a monthly fee of $16 plus $2 per movie watched.

→ So if he watches no movies in a month, he will pay $16 and for each movie watched he will pay an extra $2

You can represent the monthly cost of plan A as follows:

Plan B

Has a monthly fee of $12 plus $3 for every movie watched.

The monthly cost of the plan can be expressed as follows:

For both equations the y-interceot represents the monthly fee of the plan and the slope of the line is the cost per movie.

To determine the number of movies (x) that would make both plans cost the same for one month using a graph, you have to draw both lines and determine the point where they intercept. The x-coordinate of said point will be the number of movies that make both plans cost the same.

To draw the lines you have to determine at least two points of the line.

The easiest point will be the y-intercept, for the second point, choose any value of x, replace it in the formula and calculate the corresponding value of y. Then plot both points and draw the line.

For plan A

y-intercept, x=0

The coordinates are (0,16)

Second point, for example, for x= 2 movies

The coordinates are (2,20)

For plan B

y-intercept, x=0

The coordinates are (0,12)

Second point, for example, for x=3

The coordinates are (3,21)

The red line represents the cost with respect to the number of movies for plan A

The purple line represents the cost with respect to the number of movies for plan B

Where both lines intercept indicates the point when both plans cost the same. Said point is (4,24), which means that when you watch x=4 movies both plans will cost $24 that month.

Hello and regards 24kendalllove.

The given function is y = x^2 - 2x - 1.

The domain of a quadratic function, like this one, is the set of all values of x for which the function is defined. Since a quadratic function is defined for all real values of x, the domain of this function is all real numbers.

To find the range of the quadratic function, we must first identify whether the parabola opens up or down. In this case, the coefficient of the x^2 term is positive (1), which means that the parabola opens up.

Since the parabola opens up, the vertex of the parabola will be the lowest point on the graph. To find the vertex, we use the formula x = -b / 2a, where a and b are the coefficients of the terms x^2 and x, respectively. In this case, a = 1 and b = -2, so x = -(-2) / (2 * 1) = 1. We then plug this value of x into the function to find the corresponding y value: y = (1)^2 - 2(1) - 1 = -2.

So, the vertex of the parabola is (1, -2). Since the parabola opens up, the range of the function will be all y-values greater than or equal to the y-value of the vertex. Therefore, the range of the function is y ≥ -2.
