As a result, the rectangular prism's volume in fully factored form is:

V = (x - 1) * (l * w * h)

A 3D form with six rectangular faces is referred to as a rectangular solid. A rectangular solid's volume can be calculated using the formula V = lwh, where l denotes the solid's length, w its width, and h its height.

In this instance, we are informed that the rectangular solid's height is 17 units. Also, we are informed that the solid's base is a rectangle with an area of (x-1) square units. We can assume that the solid has length l and width w because its base is a rectangle.

Solids with six rectangular faces are known as rectangular solids. They go by the name rectangular prisms as well. Following are some examples of rectangular solids in daily life:

Laptops, school notebooks, fish tanks, cargo containers, rooms, storage sheds, refrigerators, cereal boxes, tissue boxes, cars, and more.

As a result, we have:

l * w = x - 1

The rectangular solid's volume is:

V = lwh

With l * w = x - 1 and h = 17 as substitutes, we obtain:

V = (x - 1)lw

This phrase can be factored as follows:

V = (x - 1)l * w * h

Since l * w = x - 1 and h = 17, we have:

V = (x - 1) * l * w * h

V = (x - 1) * (l * w * h)

As a result, the rectangular prism's volume in fully factored form is:

V = (x - 1) * (l * w * h)

We can write the absolute value inequality in the form |x−b| < c: |x−6| < 1

What is inequalities?

In mathematics, an inequality is a mathematical statement that indicates that two expressions are not equal. It is a statement that compares two values, usually using one of the following symbols: "<" (less than), ">" (greater than), "≤" (less than or equal to), or "≥" (greater than or equal to).

The solution set 5 < x < 7 can be rewritten as:

x > 5 (since x must be greater than 5)

x < 7 (since x must be less than 7)

To put this in the form |x−b| < c, we first find the midpoint between 5 and 7:

b = (5+7)/2 = 6

Then, we find the distance between b and either endpoint:

c = |7-6| = 1 (or |5-6| = 1)

Finally, we can write the absolute value inequality in the form |x−b| < c:

|x−6| < 1.

The probability that exactly 3 out of 6 dolphins are cured is approximately 0.3342.

This is a binomial probability problem with the following parameters:

n = 6 (number of trials)

p = 0.95 (probability of success, which is being cured)

q = 1 - p = 0.05 (probability of failure, which is not being cured)

The probability of exactly 3 dolphins being cured is given by the binomial probability formula:

P(X = 3) = (6 choose 3) * 0.95^3 * 0.05^3

where "6 choose 3" represents the number of ways to choose 3 dolphins out of 6.

Using a calculator, we can evaluate this expression as:

P(X = 3) = (6 choose 3) * 0.95^3 * 0.05^3

The equation of the parabola is y = 5x² - 6x + 1 .

What is parabola?

A parabola is a U-shaped plane curve. Any location on a parabola is at an equal distance from both the focus, a fixed point, and the directrix, a set straight line.

First, we figure out the value of c or the y intercept, we use the second point (0, 1) and substitute to the equation of the parabola. When x = 0, y = 1. So, c should be equal to 1. The parabola is y = ax^2 + bx + 1

Now, we can substitute the point (1,0) into the equation,

0 = a(1)² + b(1) + 1

0 = a + b + 1

a + b = -1

The slope at x = 1 is equal to 4 which is equal to the first derivative of the equation.

We take the derivative of the  equation ,

y = ax² + bx + 1

y' = 2ax + b

x = 1, y' = 2

4 = 2a(1) + b

4 = 2a + b

So, we have two equations and two unknowns,

2a + b = 4

a + b = -1

Solving simultaneously,

a = 5

b = -6

Therefore, the equation of the parabola is y = 5x² - 6x + 1 .

Any scale factor greater than 1 result in a expansion or increase in size. Any scale factor less than 1 result in a shrinkage or decrease in size.

What is a scale factor?

a scale factor is a ratio between the scale of a given original object(pre-image) and a new object, (after-image or image after transformation) which is the same shape but of a different size (bigger or smaller).

Example & how to use scale factor:

let's say we have a triangle with a side length of 2, 2, and 3.

then we take that triangle and dilate it with a scale factor of 2.

the new side lengths become 4, 4, and 6 because they are being multiplied by 2 because the scale factor is 2.

Explanation and answer:

1. A scale factor of 4 is an expansion because it's greater than 1

2. A scale factor of 9/7 or about 1.30 is an expansion because it's greater than one.

Answer:

No, a, h, and k behave differently in the square root function than they did in the quadratic function and/or cubic functions from the previous course. There is no variable (a) in front of the square root word in the square root function, and the shifts of the function are represented by h and k, respectively. Unlike in quadratic or cubic functions, where h stands for the vertex's horizontal shift and k for its vertical shift. The square root function's scope and range also vary from those of cubic and quadratic functions.

The inequality used is 20m ≥ 380 and Matthew needs to mow at least 19 lawns to make his goal of $380.

A mathematical comparison of two quantities using the symbols (less than), > (greater than), (less than or equal to), or is known as an inequality (greater than or equal to). Relationships between values that might not be equal, such the magnitude of two numbers or the range of values for a variable, are described as inequalities. Instead of a single value, the solutions to inequalities are sometimes stated as intervals of integers that meet the inequality. Every choice of x larger than 2 will meet the inequality, for instance, in the case of the inequality 2x + 3 > 7.

Let us suppose number of lawns mown = m.

The total earnings can be calculated as follows:

With a basic interest rate of 5%, a deposit earns $102 after 36 months. The duration and overall cost are 3 years and $782, respectively.

To resolve this issue, we can utilize the simple interest formula:

I = Prt

where I stands for interest, P for the principal (original deposit), r for interest rate, and t for the time in years.

We know that the interest earned is $102, the interest rate is 5%, and we want to find the time and total value. Let's call the principal "P" and the time "t". Then we have:

102 = P x 0.05 x 3

Simplifying this equation, we get:

102 = 0.15P

Dividing both sides by 0.15, we get:

P = 680

So the initial deposit was $680.

Now, we can calculate the time using the same formula:

102 = 680 x 0.05 x t

Simplifying this equation, we get:

102 = 34t

Dividing both sides by 34, we get:

t = 3

So the time was 3 years (or 36 months).

To find the total value, we simply add the interest earned to the initial deposit:

Total value = P + I = $680 + $102 = $782

Therefore, the time was 3 years and the total value after 36 months was $782.

Answer: The solution to the system of equations by substitution is (x, y) = (-3, -1).

The probability that a randomly chosen student who speaks French is female is 33/110 and a female student speaks French is 15/41.

What is probability?

Probability is a measure of the likelihood or chance of an event occurring. It is a number between 0 and 1, with 0 representing an impossible event and 1 representing a certain event. The probability of an event is calculated by dividing the number of ways the event can occur by the total number of possible outcomes.

a) Let's use Bayes' theorem to calculate the probability that a randomly chosen female student speaks French. Let F represent the event that a student speaks French, and let F' represent the event that a student does not speak French. Similarly, let Fm and Ff represent the events that the student is male and female, respectively. Then we have:

P(F|Ff) = P(Ff|F)P(F) / P(Ff)

where P(Ff|F) = 3/10 is the probability that a female student speaks French, P(F) = 5/22 is the overall probability that a student speaks French, and P(Ff) = (3/10)(5/22) + (2/12)(17/22) = 41/220 is the probability that a randomly chosen student is female. Thus, we have:

P(F|Ff) = (3/10)(5/22) / (41/220) = 15/41

So the probability that a randomly chosen female student speaks French is 15/41.

b) Now we want to find the probability that a randomly chosen student who speaks French is female. Let's again use Bayes' theorem, with F and F' representing the events of speaking French and not speaking French, and M and F representing the events of being male and female, respectively. Then we have:

P(Ff|F) = P(F|Ff)P(Ff) / P(F)

where P(F|Ff) = 3/10 is the probability that a female student speaks French, P(Ff) = 41/220 is the probability that a randomly chosen student is female, and P(F) = (3/10)(5/22) + (2/12)(17/22) = 5/22 is the overall probability that a student speaks French. Thus, we have:

P(Ff|F) = (3/10)(41/220) / (5/22) = 33/110

So the probability that a randomly chosen student who speaks French is female is 33/110.

Hence,  the probability that a randomly chosen student who speaks French is female is 33/110 and a female student speaks French is 15/41.

To find the average rate of change of the function f(x) over the interval [-2,4], we need to calculate the change in the function value divided by the change in the input variable over that interval:

Average rate of change = (f(4) - f(-2))/(4 - (-2))

First, we calculate f(4):

f(4) = √(4 - 2) = √2

Next, we calculate f(-2):

f(-2) = √(-2 - 2) = √(-4)

Since the square root of a negative number is not a real number, the function f(x) is not defined for x < 2. Therefore, the interval [-2,4] is not entirely within the domain of the function.

However, we can still find the average rate of change over the part of the interval that is within the domain of the function, which is [2,4]. Therefore, we need to modify the formula accordingly:

Average rate of change = (f(4) - f(2))/(4 - 2)

f(2) = √(2 - 2) = 0

Plugging in the values we get:

Average rate of change = (√2 - 0)/(4 - 2) ≈ 0.71

Therefore, the average rate of change of f(x) over the interval [-2,4] (within the domain of the function) to the nearest hundredth is 0.71.

The equation in x is 2[tex]x^{2}[/tex]-3x-$27=0, which can be solved using the quadratic formula to find the value(s) of x that satisfy the equation. The expressions derived in parts (a) and (b) are used to set up an equation involving x.

To solve this problem, we need to use the information given in parts (a) and (b) to set up an equation involving x.

(a) Let the number of large sacks Paul buys be y. The cost of each large sack is given as x, so the total amount Paul spends is:

y * x = $27

Solving for y, we get:

y = 27/x

(b) Let the number of small sacks Rula buys be z. We are told that each small sack costs $2 less than a large sack, so the cost of each small sack is:

x - $2

The total amount Rula spends is $25, so we can set up an equation:

z * (x - $2) = $25

Simplifying this equation, we get:

z = 25/(x - $2)

(c) We are told that Rula buys 4 more sacks than Paul. Using the expressions we derived in parts (a) and (b), we can set up an equation:

z = y + 4

Substituting the expressions we derived in parts (a) and (b), we get:

25/(x - $2) = 27/x + 4

Multiplying both sides by x(x - $2), we get:

25x = 27(x - $2) + 4x(x - $2)

Simplifying this equation, we get:

25x = 27x - $54 + 4x² - 8x

Rearranging terms and simplifying, we get:

2x² - 3x - $27 = 0

So the equation in x is 2x²-3x-$27=0, which we can solve using the quadratic formula to find the value(s) of x that satisfy the equation.
