Answer:

The approximate area of the region using the midpoint rule with n = 2 is about 2.8418 square units.

Step-by-step explanation:

We want to use the midpoint rule with n = 2 to approximate the area of the region bounded by the graphs of:

[tex]\displaystyle y=\sqrt[3]{16-x^3}, y=x\text{ and } x=0[/tex]

This is shown in the graph below. Our area of interest is between the green, red, and blue lines.

First, find the intersection point of the two graphs:

[tex]\displaystyle x=\sqrt[3]{16-x^3}\Rightarrow x=2\Rightarrow (2, 2)[/tex]

Therefore, we will want to approximate from x = 0 to x = 2.

Note that the red graph (cubic root) is greater than the linear function for all x in the interval [0, 2].

Since the cubic function is greater than the linear function for all x in [0, 2], the area of the region will be the linear function subtracted from the cubic function. Hence:

[tex]\displaystyle \text{Area}=\int_{0}^2\sqrt[3]{16-x^3}-x\, dx[/tex]

We will let:

[tex]f(x)=\sqrt[3]{16-x^3}-x[/tex]

The midpoint rule is given by:

[tex]\displaystyle \text{Area}\approx \sum_{i=1}^nf\left(\frac{x_{i-1}+x_i}{2}\right)\Delta x[/tex]

Since the area is on the interval [0, 2] and n = 2, find the width:

[tex]\displaystyle \Delta x=\frac{2-0}{2}=1[/tex]

Hence, our x-coordinates are x₀ = 0, x₁ = 1, and x₂ = 2.

Therefore, by the midpoint rule:

[tex]\displaystyle \text{Area}\approx \sum_{i=1}^2f\left(\frac{x_{i-1}+x_i}{2}\right)(1)[/tex]

Substitute:

[tex]\displaystyle \text{Area}\approx (1)\left(f\left(\frac{0+1}{2}\right)+f\left(\frac{1+2}{2}\right)\right)[/tex]

Evaluate:

[tex]\displaystyle \text{Area}\approx\displaystyle f\left(0.5\right)+f(1.5)[/tex]

Evaluate:

[tex]\displaystyle \text{Area}\approx(\sqrt[3]{16-(.5)^3}-(.5))+(\sqrt[3]{16-(1.5)^3}-(1.5))}\approx 2.8418[/tex]

Hence, the approximate area of the region is about 2.8418 square units.

Notes:

The exact area is 2.80436... square units.

Answer:

[tex]\huge\boxed{-\frac{2}{5}}[/tex]

Step-by-step explanation:

The slope of a line can be determined from two points via the slope formula. This is usually defined as the change in y divided by the change in x. It’s commonly represented using this formula:

Where [tex]\Delta[/tex] represents “change in.”

The slope is basically just saying the rate of increase/decrease a function has when x increases by 1 - how much does y change when x increases by 1? We can find this by taking larger values and dividing by the rate at which we took the larger values. This derives the slope formula.

We can find the change in y and x in this function by analyzing the two points given. If we look at the change between each point, we can get the change since this is a line and thus has a constant slope.

Now that we have our change in x and y, we can substitute these values into the slope formula.

Therefore, the slope of this line is [tex]-\frac{2}{5}[/tex].

Answer:

w ≤ 35

Step-by-step explanation:

Answer:

f(x) = (x-1) (x-8) (x +7)(x-5) ( x+4)

Step-by-step explanation:

The zeros of the function are written in the form

f(x) = (x-a)(x-b)..... where the a,b  are the zeros

f(x) = (x-1) (x-8) (x - -7)(x-5) ( x--4)

Rewriting

f(x) = (x-1) (x-8) (x +7)(x-5) ( x+4)

Answer:

a.  34.8; 33.06

Step-by-step explanation:

The computation is shown below;

since in the question it is mentioned that that if the price is $40 so if offered the 13% discount

So the 13% discount on $40 is

= $40 - 13% of $40

= $34.80

Now additional 5% is also provided

So,

= $34.80 - 5% of $34.80

= $33.06

Therefore the first option is correct

sin D × cos D = (4 / 5) × (3 / 5)

sin D × cos D = 12 / 25

The product of tan C and tan D will be

tan C × tan D = (3 / 4) × (4 / 3)

tan C × tan D = 1

The product of cos C and tan D will be

cos C × tan D = (4 / 5) × (4 / 3)

cos C × tan D = 16 / 15

Then the matching will be given below.

Answer:

the standard error is 153.125

Step-by-step explanation:

given that

The random sample is 256

The sample mean is $35,420

And, the standard deviation is $2,450

We need to find out the standard error

We know that

= standard deviation ÷ √random sample

= 2450 ÷ √256

= 2450 ÷ 16

= 153.125

Hence, the standard error is 153.125
