What is the simplified form of n^-6p^3

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

Final answer:

The number closest to zero on the number line from the given options is 0.3, making the correct answer C) 0.3.

Explanation:

The question asks which number is closest to zero on the number line from the given options: A) -3/8, B) 3/4, C) 0.3, D) 0.50. To find out which is closest to zero, compare the absolute values of these numbers (since we are interested in the distance from zero, not the direction).

Absolute value of A) -3/8 is 0.375

Absolute value of B) 3/4 is 0.75

Absolute value of C) 0.3 is 0.3

Absolute value of D) 0.50 is 0.5

Comparing these values, 0.3 is the smallest absolute value, which means it is the closest to zero. Therefore, the correct answer is C) 0.3.

Answer:

1 : 2

Step-by-step explanation:

Since the quadrilaterals are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{HP}{TP}[/tex] = [tex]\frac{2}{4}[/tex] = [tex]\frac{1}{2}[/tex]

Thus the ratio of perimeters is also 1 : 2

Answer:

1:2.

Step-by-step explanation:

HP and TP are corresponding sides and their lengths are  2 and 4.

Thats a ratio of 1 :2.

The perimeter is also one dimensional so the ratio of the perimeters is also 1:2.

Answer:

13

Answer:

y = -5 (x+2)

Step-by-step explanation:

We can use the point slope form of a line

y-y1 = m(x-x1) where (x1,y1) is the point and m is the slope

y-0 = -5(x--2)

y = -5 (x+2)

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:

The y-intercept indicates that the phone card started with 850 minutes. The slope indicates that 50 minutes were used per day.

Step-by-step explanation:

The graph cuts the y-axis at 850.This indicates that the phone card started with 850 minutes before it was used.

The slope of the graph is -50.This means that in every increase of one in the input variable (number of days), you get a decrease of 50 in the output variable (number of minutes remaining). This indicates every day, 50 minutes were used, hence 50 minutes reduced from the card per day.

The answer is A. The y-intercept indicates that the phone card started with 850 minutes. The slope indicates that 50 minutes were used per day.

This is because she started with 850 and the graph shows a decrease, so this means that she loses 50 per day or that she uses 50 per day.

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

Answer:

x = √y+18

Step-by-step explanation:

Given

[tex]y = x^2-18[/tex]

In order to solve the equation for x, we have to isolate x on one side of the equation

So,

[tex]y+18 = x^2 -18 + 18\\y + 18 = x^2[/tex]

We have to find the value for x, so taking square root on both sides

[tex]\sqrt{x^2} = \sqrt{y+18}[/tex]

Solving the squre root

x = [tex]x = \sqrt{y + 18}[/tex]

Hence,

x = √y+18 is the correct answer ..

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.

Answer:

2/3

Step-by-step explanation:

Y varies directly as x

Y =kx

Y=6 when x = 72

First find the relationship between y and x.

i.e find the value of k

Substitute the value of x and y

6 = k *72

Make k the subject of the formula

K = 6/72

K= 1/12

:. The rlationship between x and y is

Y = 1/12x

When x is 8

Y = 1/12 * 8

Y = 8/12

Y = 2/3 and that is the answer

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]

[tex]72y=48[/tex]

[tex]y=\frac{48}{72}[/tex] = [tex]\frac{2}{3}[/tex]

Answer:

1/25

Step-by-step explanation:

The probability of guessing the first question correct is 1/5

The probability of guessing the second question correct is 1/5

Since they are independent

P(correct, correct) = P(1st correct) * P(2nd correct)

                               = 1/5 * 1/5

                               = 1/25

Answer:

Felicia is 7 years old

Explanation:

The variable, d, can represent Danny's age.

The variable, f, can represent Felicia's age.

Basically, using the information provided, you can make two equations.

1.) d - f = 21

2.) d + f = 35

This is a system of equations. To solve for this, I'm going to subtract the 2 equations:

    d - f = 21

-   d + f = 35

-------------------------

    -2f = -14

       f = 7

If Felicia is 7, and they're total ages added is 35, subtract 7 form 35

35 - 7 = 28

So, Danny would be 28.

To double check your answers;

28 + 7 = 35

28 - 7 = 21

So Felicia is 7 years old. I hope this helps! :)

Answer: first option.

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:

Answer:

$12

Step-by-step explanation:

If x is the price that George pays for a student ticket, then:

19 = ⅓ x + 15

To solve for x, first subtract 15 from both sides:

19 - 15 = ⅓ x

4 = ⅓ x

Then multiply both sides by 3:

4 × 3 = x

12 = x

Answer:

1/3x + 15 = 19

Step-by-step explanation:

Well this is a simple equation where you write it out EXCACTLY like the question says, the 1/3 is the 1/3 the price of a student ticket and add the x to represent the unknown amount (student ticket), the 15 represents the plus $15.00 which equals 19

Factor by grouping!

[tex]y^2(3y^2-5)+1(3y^2-5)\\(3y^2-5)(y^2+1)[/tex]

The polynomial 3y^4 - 2y^2 - 5 does not appear to be factorable with integer values. The reference to placing the factors in a particular location on a grid would likely relate to a tool or diagram provided by your instructional material.

To factor the cubic polynomial 3y4 - 2y2 - 5, we first find the common factor which in this case is none. The next step is to try grouping, and if that's not possible, we can solve the polynomial using the quadratic formula or synthetic division. However, this polynomial does not seem to be factorable with integer values.

Unfortunately, without additional context, it's not clear what grid the problem refers to, or where the location you're supposed to place the factors is. It's likely this refers to some sort of tool or diagram provided by your teacher or textbook. In general, you would write down the factors in their proper locations in that tool or diagram, according to the rules or guidelines you were given.

[tex]6\frac{1}{3}=\frac{6*3+1}{3}=\frac{19}{3}[/tex]

step 2

we know that

A teacher reviews 9/2 papers per hour

using proportion

Find how many papers will the teacher review in 19/3 hours

Let

x-----> the number of papers

[tex](9/2)/1=x/(19/3)[/tex]

[tex]x=(19/3)(9/2)[/tex]

[tex]x=28.5\ papers[/tex]

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.
