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.

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]

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.

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:

1). 1 decade

2). 2 decades

Step-by-step explanation:

Number of years in decade = 10 years

1). When we are calculating the population of Florida between 1840 to 1850,

Number of years between 1850 and 1840 = 1850 - 1840

                                                                      = 10 years

So number of decades between 1840 and 1850 = [tex]\frac{10}{10}[/tex] = 1 decade

2). Number of years between 1840 and 1860 = 1860 - 1840

                                                                           = 20 years

Therefore, number of decades between this gap = [tex]\frac{20}{10}=2[/tex] decades

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

Answer:

x=9

Step-by-step explanation:

3 ^ (x-4) = 243

Rewrite 243 as a power of 3

3 ^ (x-4) =3^5

Since the bases are the same, the exponents are the same

x-4 =5

Add 5 to each side

x-4+4 = 5+4

The solutions of the quadratic equation 3x² + 9x + 17 = 0 are x₁ = (-9 + √(123)i) / 6 and x₂ = (-9 - √(123)i) / 6, where "i" represents the imaginary unit.

To find the solutions of the quadratic equation 3x² + 9x + 17 = 0, we'll use the quadratic formula:

x = (-b ± √(b² - 4ac)) / 2a.

Here, a = 3, b = 9, and c = 17. We'll plug these values into the formula and simplify the expression step-by-step.

Step 1: Calculate the discriminant (Δ) using the formula Δ = b² - 4ac.

Δ = (9)² - 4 * 3 * 17

Δ = 81 - 204

Δ = -123

Step 2: Substitute the values of a, b, and Δ into the quadratic formula.

x = (-9 ± √(-123)) / 2 * 3

Step 3: Since the discriminant (Δ) is negative, the quadratic equation has no real solutions. Instead, it has two complex solutions.

Step 4: Simplify the expression under the square root.

x = (-9 ± √(-123)) / 6

Step 5: Now, we deal with the square root of a negative number, which is denoted by "i" in the complex number system. √(-123) = √(123)i.

Step 6: Substitute the value of √(-123) back into the equation.

x = (-9 ± √(123)i) / 6

Step 7: Divide both the real and imaginary parts by 6 to get the two complex solutions.

x₁ = (-9 + √(123)i) / 6

x₂ = (-9 - √(123)i) / 6

Final answer:

The quadratic equation 3x^2 + 9x + 17 = 0 has no real solutions because the discriminant is negative. The solutions are complex numbers and can be expressed as x = -3/2 ± √(123)/6 × i.

Explanation:

To find the solutions of the quadratic equation 3x^2 + 9x + 17 = 0, we will use the quadratic formula, which is x = (-b ± √(b^2 - 4ac)) / (2a) for a quadratic equation of the form ax^2 + bx + c = 0. In our case, a = 3, b = 9, and c = 17. Plugging these values into the formula gives:

x = (-(9) ± √((9)^2 - 4(3)(17))) / (2(3))

x = (-9 ± √(81 - 204)) / 6

x = (-9 ± √(-123)) / 6

Since the discriminant (the part under the square root, b^2 - 4ac) is negative, the equation has no real solutions. Instead, the solutions are complex numbers:

x = (-9 ± √(-123)i) / 6

The final solutions can be expressed as:

x = -3/2 ± √(123)/6 × i

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

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.
