Answer:

[tex]-3m^{12}{n^{6} }[/tex]

Step-by-step explanation:

To begin simplifying this, we can first divide the coefficients, giving us:

[tex]\frac{-3m^{5}n^{4} }{m^{-7} n^{-2} }[/tex]

We know that when dividing exponents, this means we need to subtract the exponent on the denominator from the numerator. This gives us:

[tex]\frac{-3m^{5+7} n^{4+2} }{1}[/tex]

Now, simplifying this gets:

[tex]-3m^{12}{n^{6} }[/tex]

Answer:

Letter B is the answer.

Answer:

X = -1   Y = 4

Step-by-step explanation:

Put the 7y over so it is 27-7y

after that you fill in the x on the top formula with (27-7y)

From there you solve like normal for Y, which ends out being 4.

Once you have that you can plug 4 into the Y spot in the bottom formula and just solve for X

There are 154,440 different ways for the names of the top 5 participants to be listed on the leaderboard.

To determine the number of ways the names can be listed for the top 5 participants on the leader board, you can use the concept of permutations. The formula for permutations is:

[tex]\[ P(n, r) = \frac{n!}{(n - r)!} \][/tex]

where [tex]\( n \)[/tex] is the total number of items and [tex]\( r \)[/tex] is the number of items to be selected.

In this case, you have 13 participants, and you want to select and order the top 5 participants. So, the formula becomes:

[tex]\[ P(13, 5) = \frac{13!}{(13 - 5)!} \][/tex]

Now, calculate the permutations:

[tex]\[ P(13, 5) = \frac{13!}{8!} \][/tex]

[tex]\[ P(13, 5) = \frac{13 \times 12 \times 11 \times 10 \times 9 \times 8!}{8!} \][/tex]

[tex]\[ P(13, 5) = 13 \times 12 \times 11 \times 10 \times 9 \][/tex]

Now, calculate the result:

[tex]\[ P(13, 5) = 154,440 \][/tex]

So, there are 154,440 different ways for the names of the top 5 participants to be listed on the leader board.

We have been given that ∠Q is an acute angle such that [tex]\text{tan}(Q)=0.04[/tex]. We are asked to find the measure of angle Q to nearest tenth of a degree.

We will use arctan to solve for measure of angle Q as:

[tex]Q=\text{tan}^{-1}(0.04)[/tex]

Now we will use calculator to solve for Q as:

[tex]Q=2.290610042639^{\circ}[/tex]

Upon rounding to nearest tenth of degree, we will get:

[tex]Q=2.3^{\circ}[/tex]

Therefore, measure of angle Q is approximately 2.3 degrees.

The measure of angle Q, rounded to the nearest tenth of a degree, is approximately 131.4 degrees.

To approximate the measure of angle [tex]\( \angle Q \)[/tex] given [tex]\( \tan Q = 0.04 \)[/tex], follow these steps manually:

1. Use the inverse tangent function : Use the inverse tangent function [tex](arctangent or \( \tan^{-1} \)) to find \( Q \)[/tex].

2. Calculate [tex]\( Q \)[/tex] : Calculate [tex]\( Q = \tan^{-1}(0.04) \)[/tex].

3. Convert to degrees : The result of [tex]\( \tan^{-1}(0.04) \)[/tex] will give you [tex]\( Q \)[/tex] in radians. To convert radians to degrees, multiply by [tex]\( \frac{180}{\pi} \)[/tex].

- [tex]\( Q = \tan^{-1}(0.04) \)[/tex]

- Suppose [tex]\( \tan^{-1}(0.04) \approx 2.29161 \)[/tex] radians.

- Convert radians to degrees: [tex]\( Q \approx 2.29161 \times \frac{180}{\pi} \)[/tex]

- [tex]\( Q \approx 2.29161 \times 57.2958 \)[/tex]

- [tex]\( Q \approx 131.384 \)[/tex] degrees (this is the exact calculated value).

4. Round to the nearest tenth :

Since we need to round to the nearest tenth of a degree,

- [tex]\( Q \approx 131.4^\circ \)[/tex].

Therefore, the measure of [tex]\( \angle Q \)[/tex], rounded to the nearest tenth of a degree, is approximately [tex]\( 131.4^\circ \)[/tex].

So the right answer is of option A.

The measure of the arc DF is 86 degrees if the measure of the major arc is 274 degrees option (D) is correct.

It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

We have:

In the diagram below, DE and EF are tangent to O.

Let x be the measure of arc DF.

The complete revolution around the center = 360 degree

Major arc + Minor arc = 360

274 + x = 360

x = 86 degrees

Thus, the measure of the arc DF is 86 degrees if the measure of the major arc is 274 degrees option (D) is correct.

Answer:

The average force applied to the baseball is 8.25kN

Step-by-step explanation:

This problem bothers on the impulse of a force

We know that the change in momentum is expressed as

Ft= mv-mu

Given

Ft=16.5 kg-ms

Time t of impact =0.00200s

The force applied can be solved for

By making F subject of formula

F= (mv-mu)/t

F=16.5/0.002

F= 8250N

F= 8.25kN

Final answer:

The average force applied to the baseball is calculated to be 8250 Newtons, based on the given change in momentum of 16.5 kg-ms and the time of impact of 0.00200 seconds.

Explanation:

The student is asking how to calculate the average force applied to a baseball during collision with a bat, given that the baseball's change in momentum (impulse) is 16.5 kg-ms and the time of impact is 0.00200 seconds.

To find the average force (Favg), we can use the formula derived from Newton's second law, which relates force, change in momentum (impulse), and time:

Favg = \\Delta p / t

Where:

Plugging in the values we have:

Favg = 16.5 kg-ms / 0.00200 s

Doing the calculation:

Favg = 8250 N

Therefore, the average force applied to the baseball is 8250 Newtons.

Step-by-step explanation:

Key to this question is assume that each exchange preserves the total dollar amount of Nick’s money.

If He exchanges all his $5 bills for $1 bills, it means that a $5 bill will result in 5 $1 bills as such, if he had x number of $5 bill, after the exchange, he would have 5x $1 bills.

then all his $20 bills for $5 bills, it means that for each $20 bill, he gets 4 $5 bills which means that if he had y number of $5 bills, after the exchange, he would have 4y $5 bills.

and finally all his $100 bills for $20 bills, then he must have received 5 $20 bills for each $100 such that if he had z number of $100 bills before the exchange, he would have 5z number of $20 bills after the exchange. Given that originally he had 17 bills and later 77 bills then

x + y + z  = 17

5x + 4y + 5z = 77

Multiplying the first equation by 5,

5x + 5y + 5z = 85

5x + 4y + 5z = 77

subtract 2 from 1

y = 8

Answer:

2. Denote two pieces: x, y

x + y = 40

x = 2y + 10

=> 2y + 10 + y = 40 => 3y = 30 => y = 10 => x = 2 x 10 + 10 = 30

=> Solution: 10 and 30

3. Denote 4 consecutive number: 2k, 2k+2, 2k+4, 2k+6

(2k + 2k + 4) x 2 + 20 = 2 x (2k + 6)

=> 8k + 28 = 4k + 12

=> 4k = -16

=> k = -4

=> Solution: -8, -6, -4, -2

Answer:

11 ft

Step-by-step explanation:

The equation for the volume of a cone is:

V = 1/3(3.14)r^2h

V = 414.48

r = 6

Plug in those values and solve for h:

414.48 = 1/3(3.14)(6)^2h

414.48 = 37.68h ; divide both sides by 37.68

11 = h

The missing height is 11ft.

Answer:

.0099

Step-by-step explanation:

right answer

The proportion of exam scores are between 82 and 89.2 points is 0.3330.

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

Given:

mean = 87 points and

standard deviation = 8 points.

Now, using

Z= [tex]x- \mu / \sigma[/tex]

z= 104.6 - 87 / 8

z= 2.2

again, Z= [tex]x- \mu / \sigma[/tex]

z= 108.2- 87 / 8

z= 2.65

So, the proportion is

P(x<108.20)-P(x<104.60)

=P(Z<2.65)-P(Z<2.2)

= 0.9960-0.9861

=0.0099

Answer:

C.   $176.000

Step-by-step explanation:

Linear regression requires sufficient data points for analysis, which are not provided, making it impossible to calculate an estimated price for a 1700 ft2 home without additional information.

To estimate a fair price for a 1700 ft2 home using linear regression, we would require more data points with corresponding house prices to create a regression model. Since we're not provided with sufficient data in the question, and there's no explicitly provided regression equation or coefficients, it's not possible to accurately calculate the estimated price for a home of a given square footage using linear regression. However, if we had such data, we would typically plot square footage on the x-axis and house price on the y-axis, calculate the slope and intercept coefficients of the regression line, and then use the regression equation y = mx + b (where y is the estimated house price, m is the slope, x is the square footage, and b is the y-intercept) to predict the price of the house with given square footage
