Answer:

5x^7 + 4x^4  - 2x^2 - 4x  - 10

Step-by-step explanation:

(x^4-9x+5x^7)+(5x-10+3x^4-2x^2) = 4x^4 - 9x + 5x^7  + 5x - 10 - 2x^2

                               = 4x^4 - 9x + 5x^7  + 5x - 10 - 2x^2

                                = 4x^4 - 4x + 5x^7  - 10 - 2x^2

                                = 5x^7 + 4x^4  - 2x^2 - 4x  - 10

Answer:

B

Step-by-step explanation:

The recommended sample size n for point estimates is:

n = NX / (N + X - 1)

where N is the population size, and X is defined as:

X = Z² p (1 - p) / E²

where Z is the critical value, p is the sample proportion, and E is the margin of error.

Assume a confidence level of level of 95% and a margin of error of 5%.

α = 0.05, Z(α/2) = 1.96

E = 0.05

Of the 40 units tested, 2 had lifespans less than 26 days.  So the proportion is:

p = 2/40 = 0.05

Therefore:

X = (1.96)² (0.05) (1 - 0.05) / (0.05)²

X = 73

Given N = 2000:

n = (2000) (73) / (2000 + 73 - 1)

n = 70.45

Rounding, the recommended sample size is 70.

Step-by-step explanation:

You know that the height of the smaller cylinder is 6 cm and the height of the larger cylinder is 18 cm, then you can find the volume ratio. This  is:

[tex]Volume\ ratio=(\frac{6cm}{18cm})^3\\\\Volume\ ratio=\frac{1}{27}[/tex]

Knowing that the volume of the larger cylinder is 40,635 cubic centimeters, you need to multiply it  by the volume ratio to find the volume of the smaller cylinder.

Therefore:

[tex]V_{smaller}=\frac{1}{27}(40,635\ cm^3)\\\\V_{smaller}=1,505\ cm^3[/tex]

Answer:

Filling in the blanks: (rectangular prism) (cylinder) (rectangular prism)

The cylinder has the greater volume because the cylinder fits within the rectangular prism with extra space between the two figures.

A prism is a three-dimensional object.

There are triangular prism and rectangular prism.

We have,

We can see this by comparing the formulas for the volumes of the two shapes.

The volume V of a rectangular prism with length L, width W, and height H is given by:

V = L x W x H

The volume V of a cylinder with radius r and height H is given by:

V = πr²H

Now,

We are told that the length of each side of the prism base is equal to the diameter of the cylinder.

Since the diameter is twice the radius, this means that the width and length of the prism base are both equal to twice the radius of the cylinder.

So we can write:

L = 2r

W = 2r

Substituting these values into the formula for the volume of the rectangular prism, we get:

V prism = L x W x H

V prism = 2r x 2r x H

V prism = 4r²H

Substituting the radius and height of the cylinder into the formula for its volume, we get:

V cylinder = πr^2H

To compare the volumes,

We can divide the volume of the cylinder by the volume of the prism:

V cylinder / V prism = (πr²H) / (4r²H)

V cylinder / V prism = π/4

π/4 is greater than 1/1,

Thus,

The cylinder has a greater volume.

The cylinder fits within the rectangular prism with extra space between the two figures because the cylinder is inscribed within the prism, meaning that it is enclosed within the prism but does not fill it completely.

Hope it helped you

Answer:

The answer is : 2/3

Step-by-step explanation:

Given is that y varies directly as x.

Means as y increases or decreases, x also increases or decreases.

When y is 6 when x is 72,

So, when x = 8, we have to find y.

We can write the relation as follows:

[tex]\frac{6}{y}= \frac{72}{8}[/tex]

Answer: Slope = 3

Step-by-step explanation:

On a 2D-Plane, any two lines with the same slope and a different y-intercept will be parallel

Knowing this, any line with the same slope as our given line and a different y-intercept will be parallel to it

Therefore, any line with a slope of 3 and a y-intercept other than 5 will be parallel to y = 3x + 5

The answer you are looking for is a slope of 3.

Parallel lines have the same slope (M value in Y = MX + B), but different y-intercepts (B value in Y = MX + B) For example, y = 3x + 7 would be parallel to the line given above, since they slope is the same, but the y-intercept is different.

Answer:

3.2 miles

Step-by-step explanation:

The "mean" of a set of numbers is the average. To get this, you add up all of the numbers and then divide by however many there are. So, let's lay out the races that Kim ran.

1, 1, 1, 2, 2, 2, 2, 2, 2, 5, 5, 5, 5, 10

These numbers add up to 45 total miles ran. You can add them up individually or make an equation.

x = (3 × 1) + (6 × 2) + (4 × 5) + (1 × 10)

x = 3 + 12 + 20 + 10

x = 15 + 30

x = 45

Now, divide by the total number of races, 3 + 6 + 4 + 1 = 14

So, the mean will be

45 ÷ 14 = 3.21 or about 3.2

Step-by-step explanation:

Answer:

The value of CD is 2√5

Step-by-step explanation:

* Lets describe the figure to know its name

- ABCD is a quadrilateral

∵ BC parallel to AD

∵ BC = 6 units and AD = 8 units

- The quadrilateral which has two parallel sides not equal in length is a

 trapezoid

∴ ABCD is a trapezoid, where BC and AD are its bases

∵ BA perpendicular to AD

∴ BA is the height of the trapezoid

- The area of the trapezoid = 1/2 (base 1 + base 2) × its height

∵ The bases of the trapezoid are BC and AD

∵ BC = 6 and AD = 8

∵ Its area = 28 units²

∴ 1/2 (6 + 8) × height = 28

∴ 1/2 (14) × height = 28

∴ 7 × height = 28 ⇒ divide both sides by 7

∴ height = 4

∵ The height is BA

∴ BA = 4 unit

- To find the length of CD draw a perpendicular line from C to AD and

 meet it at E

∵ BA and CE are perpendicular to AD

∴ BA // CE

∵ BC // AD

- Perpendicular lines between parallel lines are equal in lengths

∴ BA = CE and BC = AE

∵ BA = 4 and BC = 6

∴ CE = 4 and AE = 6

∵ AD = 8 units

∵ AD = AE + ED

∴ 8 = 6 + ED ⇒ subtract 6 from both sides

∴ ED = 2 units

- In ΔCED

∵ m∠CED = 90°

∴ CD = √[(CE)² + (ED)²] ⇒ Pythagoras theorem

∵ CE = 4 and ED = 2

∴ CD = √[(4)² + (2)²] = √[16 + 4] = √20 = 2√5

* The value of CD is 2√5

Final answer:

The value of the unknown side CD in quadrilateral ABCD can be found using the area of a trapezoid formula and the Pythagorean theorem. Given the area, and the lengths of BC and AD, we calculated that CD equals 8 units.

Explanation:

The student has asked to find the value of CD in a quadrilateral ABCD, where BC is parallel to AD, BA is perpendicular to AD, the area of quadrilateral ABCD is 28 square units, BC is 6 units, and AD is 8 units.

Since BA is perpendicular to AD and BC is parallel to AD, we can determine that ABCD is a trapezoid with AB and CD as the non-parallel sides. The area of a trapezoid is given by the formula Area = ½ × (sum of parallel sides) × height. So we have:

½ × (AD + BC) × height = 28
½ × (8 + 6) × height = 28
½ × 14 × height = 28
7 × height = 28
height = 4 units

Since BA is perpendicular to AD, and given BA is the height of the trapezoid, this means that AB = 4 units. Now, because ABCD has right angles at A and B, triangles ABD and ABC are right triangles and we can use the Pythagorean theorem to calculate CD.

In triangle ABD:

Since CD is the hypotenuse of triangle ABD:

Therefore, the correct answer is CD = 8 units.

Step-by-step explanation:

The solution to the both system of equations A and B are (3.875, 2.375) for system A and (4.133, 2.289) for system B.

Linear equations involve one or more expressions including variables and constants and the highest exponent of the variable is 1.

System of linear equations involve two or more linear equations.

Consider system A.

x + 3y = 11

15x − 3y = 51

Adding both equations,

16x = 62

x = 3.875

3y = 7.125

y = 2.375

Consider system B.

x + 3y = 11

15x = 62 ⇒ x = 4.133

3y = 6.867

y = 2.289

Hence the solutions are (3.875, 2.375) for system A and (4.133, 2.289) for system B.

A teacher that reviews 4.5 papers an hour would be able to review approximately 28 papers in 6-1/3 hours, rounding down to the nearest whole paper.

To solve this math problem, you'll need to multiply the amount of papers that the teacher can review in one hour by the total amount of hours they worked. The teacher reviews 4.5 papers per hour, and they will be working for 6.33 hours (which is the decimal equivalent of 6-1/3 hours). Let's do the math:

4.5 papers/hour * 6.33 hours = 28.485 papers

Therefore, the teacher would be able to review approximately 28 papers in 6-1/3 hours. Please note that the number of papers reviewed has been rounded down in this scenario to remain realistic - a paper can either be reviewed or not reviewed and we cannot count half-reviewed papers.
