We have to find the area under the graph but since we are not given the graph ,So let's learn how it is done. To estimate the area under the graph of function f from x, you can use rectangles. Here's how you can do it:

Step 1: Divide the interval [a, b] into six equal subintervals.
Step 2: Calculate the width of each rectangle by dividing the total width of the interval [a, b] by the number of rectangles (in this case, 6).
Step 3: For each subinterval, find the value of the function f at the right endpoint of the subinterval.
Step 4: Multiply the width of the rectangle by the value of the function at the right endpoint to find the area of each rectangle.
Step 5: Add up the areas of all six rectangles to estimate the total area under the graph of f from x.

Answer:21.46 is her profit

Step-by-step explanation:

Answer:

x = 23.33333

y = 35

Step-by-step explanation:

3x+2y=70

Geometric figure: Straight Line

Slope = -3.000/2.000 = -1.500

x-intercept = 70/3 = 23.33333

y-intercept = 70/2 = 35

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 35/1 so this line "cuts" the y axis at y=35.00000

y-intercept = 70/2 = 35

Calculate the X-Intercept :

When y = 0 the value of x is 70/3 Our line therefore "cuts" the x axis at x=23.33333

x-intercept = 70/3 = 23.33333

Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 35.000 and for x=2.000, the value of y is 32.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 32.000 - 35.000 = -3.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

Slope = -3.000/2.000 = -1.500

Geometric figure: Straight Line

Slope = -3.000/2.000 = -1.500

x-intercept = 70/3 = 23.33333

y-intercept = 70/2 = 35

Answer:

volume of trapezoidal prism = 15x^2 cubic units

Step-by-step explanation:

First, area of the trapezoidal bases.

Parallel sides measure x and 2x, for an average of 1.5x.

Height = x

Area of trapezoidal base = 1.5x*x = 1.5x^2

Volume of prism = area base * height

(length does not matter, height does)

= 1.5x^2 * 10 = 15x^2

The volume of the prism is 15x² cubic units if the oblique prism has trapezoidal bases and a vertical height of 10 units option (B) 15x² cubic units is correct.

It is defined as the quadrilateral having four sides in which two sides are parallel to each other, it is a 2-dimensional geometry.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

It is given that:

An oblique prism has trapezoidal bases and a vertical height of 10 units.

As we know, the area of the trapezoidal bases:

From the figure:

Height = x

Area of trapezoidal base = (1.5x)(x) = 1.5x²

The volume of prism = area base×height

= 1.5x²×10 = 15x² cubic units

Thus, the volume of the prism is 15x² cubic units if the oblique prism has trapezoidal bases and a vertical height of 10 units option (B) 15x² cubic units is correct.

Given function is:y = 3√x - 5To find the inverse of the function, we can interchange x and y and solve for y. Let's do that:x = 3√y - 5x + 5 = 3√y(x + 5)/3 = √y(x + 5)²/9 = yThus, the inverse of the function is: y = (x + 5)²/9To determine whether the inverse is a function, we need to check if for every value of x, there is only one value of y. In other words, the inverse passes the vertical line test.If we sketch the graph of the inverse, we get:graph{(x+5)^2/9 [-10, 10, -5, 5]}The graph passes the vertical line test.

Answer: 20%

Step-by-step explanation:

The method-of-moments estimator for θ is θ = (2 * Y_bar) / 3.

To derive the method-of-moments estimator for θ using the given interval and variables, follow these steps:

1. Given that y1, y2,..., yn are independent and identically distributed uniform random variables on the interval (0, 3θ), their probability density function (pdf) can be expressed as f(y) = 1/(3θ) for 0 < y < 3θ.

2. Calculate the expected value (mean) of the uniform distribution. The expected value E(Y) for a uniform distribution on the interval (0, 3θ) is (3θ - 0) / 2 = 3θ / 2.

3. The method-of-moments estimator involves matching the sample moments with the population moments. In this case, we match the sample mean with the population mean. Let Y_bar be the sample mean, which can be calculated as Y_bar = (y1 + y2 + ... + yn) / n.

4. Now, equate the sample mean Y_bar with the population mean E(Y) to get the method-of-moments estimator for θ:

Y_bar = 3θ / 2

5. Solve for θ:

θ = (2 * Y_bar) / 3

So, the method-of-moments estimator for θ is θ = (2 * Y_bar) / 3, where Y_bar is the sample mean of the independent and identically distributed uniform random variables on the interval (0, 3θ).

The two possible values for t are:

t1 = (-1 + √5) / 2

t2 = (-1 - √5) / 2

Solving the equation gives us
t1 = -1 + √5

t2 = -1 - √5

Let's write an equation using the variable t to represent the number of tourists who visited Venice for multiple nights in 2019.

According to the given information, the number of tourists who visited Venice just for the day is 19 million. We need to find the number of tourists who visited for multiple nights, so we'll multiply this by some factor.

The equation can be written as:

19 million = t times (19 million + t)

Simplifying this equation:

19 million = 19 million t +\(t^2\)

Rearranging the equation to standard form:

\(t^2\) + 19 million t - 19 million = 0

Now we have a quadratic equation. To solve it, we can either factor it or use the quadratic formula.

However, we can simplify the equation further by dividing both sides by 19 million:

\(t^2\) + t - 1 = 0

Now we have a simplified quadratic equation. We can use factoring, completing the square, or the quadratic formula to solve it. However, the quadratic equation does not easily factor, so we can use the quadratic formula:

t = (-b ± √(\(b^2\) - 4ac)) / (2a)

For this equation, a = 1, b = 1, and c = -1. Substituting these values into the quadratic formula, we get:

t = (-1 ± √(\(1^2\) - 4(1)(-1))) / (2(1))

Simplifying further:

t = (-1 ± √(1 + 4)) / 2

t = (-1 ± √5) / 2

Therefore, the two possible values for t are:

t1 = (-1 + √5) / 2

t2 = (-1 - √5) / 2

By solving these we get,

t1 = (-1 + √5) / 2 \(\times\)(2/2)

= (-1 + √5) / (2/2)

= (-1 + √5) / 1

= -1 + √5

t2 = (-1 - √5) / 2 \(\times\)(2/2)

= (-1 - √5) / (2/2)

= (-1 - √5) / 1

= -1 - √5

The point- slope form of the line is y-5 = -0.25(x+6).

What is line?

A line is an one-dimensional figure. It has length but no width. A line can be made of a set of points which is extended in opposite directions to infinity. There are straight line, horizontal, vertical lines or may be parallel lines perpendicular lines etc.

A line with a slope of –1/4 passes through the point (–6,5)

Any line in point - slope form can be written as

y - y₁= m(x -x₁) -------(1)

where,

y= y coordinate of second point

y₁ = y coordinate of first point

m= slope of the line

x= x coordinate of second point

x₁ = x coordinate of first point

In the given problem (x₁ , y₁) = (-6,5) and m= -1/4

Putting all these values in equation (1) we get,

y-5= (-1/4) (x- (-6))

⇒ y-5 = -0.25(x+6)

Hence, the point- slope form of the line is y-5 = -0.25(x+6).

1: We can use the formula to calculate the present value of the annuity:

P = A x [1 - (1+i)^-n] / i

Where

P = Present Value

A = Annuity

i = Interest Raten = Number of payments

2: Calculate the present value of each payment using the formula:

P1 = 25000 / (1.06)⁵

P2 = 25000 / (1.06)⁶

P3 = 25000 / (1.06)⁷

P4 = 25000 / (1.06)⁸

P5 = 25000 / (1.06)⁹

P6 = 25000 / (1.06)¹⁰

P7 = 25000 / (1.06)¹¹

P8 = 25000 / (1.06)¹²

3: Substitute the values into the formula to find the present value:

P = P1 + P2 + P3 + P4 + P5 + P6 + P7 + P8

P = (25000 / (1.06)⁵) + (25000 / (1.06)⁶) + (25000 / (1.06)⁷) + (25000 / (1.06)⁸) + (25000 / (1.06)⁹) + (25000 / (1.06)¹⁰) + (25000 / (1.06)¹¹) + (25000 / (1.06)¹²)

The cost of 10 cereal bars at the cheaper shop (i.e. at supermarket) = £7.5

We can observe that at corner shop, 5 cereal bars cost 4 pounds.

So, using unitary method, 1 cereal bar costs 5/4 = 0.8 pounds.

And at supermarket, 2 cereal bars cost 1.50 pounds.

so, using unitary method one cereal bar costs 1.5/2 = 0.75 pounds.

This means that supermarket is cheaper than the corner shop.

Now we need to finnd the cost of 10 cereal bars at the cheaper shop i.e., to find the cost of 10 cereal bars at supermarket.

Let us assume that the cost of 10  cereal bars is m pounds.

Using unitary method the cost of 10 cereal bars at supermarket would be:

x = (number of cereal bars) × (cost of each cereal bar)

The sum of two rational numbers is rational because the sum of any two fractions with rational numerators and denominators can be expressed as a fraction with a rational numerator and denominator.

A rational number is any number that can be expressed as a ratio of two integers, where the denominator is not equal to zero. For example, 1/2, -3/4, 6/5, and 0 are all rational numbers.

When we add two rational numbers together, we can use the following formula:

a/b + c/d = (ad + bc) / bd

where a, b, c, and d are integers and b and d are not equal to zero.

This formula tells us that the sum of two rational numbers is also a rational number. The numerator of the sum is found by cross-multiplying the fractions, and the denominator of the sum is found by multiplying the denominators.

For example, if we want to add 1/2 and 2/3 together, we can use the formula above:

1/2 + 2/3 = (1 x 3 + 2 x 2) / (2 x 3) = 7/6

Therefore, the sum of 1/2 and 2/3 is 7/6, which is also a rational number. This formula can be used to prove that the sum of any two rational numbers is also a rational number.

A rational number is a number that can be written as \(\dfrac{a}{b}\) where \(a,b\in\mathbb{Z}\) and \(b\not=0\).

If one number is \(\dfrac{a}{b}\) and the other is \(\dfrac{c}{d}\), where \(b,d\not=0\), their sum is \(\dfrac{a}{b}+\dfrac{c}{d}=\dfrac{ad+bc}{bd}\). Since the set of integers is closed under addition and multiplication, we can write that \(\dfrac{ad+bc}{bd}=\dfrac{e}{f}\) where \(e,f\in\mathbb{Z}\) and \(f\not=0\), thus proving the sum of two rational numbers is a rational number.

The value of x is 5.

According to the given question.

We have
