The the distance between the two stations is 300km, then the speed of first motorcyclist is 63 km/h and speed of second-motorcyclist is 70 km/h.

The distance between the "two-stations" is given to be 300 km;

Let the speed of first-motorcyclists be x km/h

and let the speed of second-motorcyclists be (x + 7) km/h,

So, the Distance covered by first motorcyclist after 2 hours is = 2x km

and distance covered by second motorcyclist after 2 hours is = 2(x+7) km

⇒ 2x + 14 km,

So, the distance not covered by them after 2 hours is = 300 - (2x+2x+14) km.

The distance between the motorcyclist after 2 hours is 34 km,

Which means ,

⇒ 300-(4x+14) = 34

⇒ 300 - 4x - 14 = 34

⇒ 4x = 300 - 48

⇒ x = 63,

So, Speed of first-motorcyclists is 63 km/h, and

Speed of second-motorcyclist is = (63 + 7) = 70 km/h.

The given question is incomplete, the complete question is

The distance between two stations is 300 km. Two motorcyclists start simultaneously from these stations and move towards each other. The speed of one of them is 7 km/h more than that of the other. If the distance between them after 2 hours of their start is 34 km, find the speed of each motorcyclist.

(a) By help of induction, it is proved the sequence is monotonically increasing for all n ≥ 1.

(b) The sequence is bounded above by 3 for all n ≥ 1.

(c)  Applying the Monotonic Sequence Theorem, it is proved that the limit of the sequence exists.

(d) limn→[infinity] an is 2.

(e) The series X[infinity] n=1 an is convergent

(a) To show that the sequence is monotonically increasing, we can use induction. Let's first consider the base case, n = 1. We have a1 = √2 and a2 = √2 + a1 = √2 + √2 > a1, so the sequence is increasing for n = 1. Now, let's assume that the sequence is increasing for n = k, so ak+1 > ak. Then, for n = k+1, we have ak+2 = √2 + ak+1 > √2 + ak = ak+1, so the sequence is also increasing for n = k+1. Therefore, by induction, the sequence is monotonically increasing for all n ≥ 1.

(b) To show that the sequence is bounded above by 3, we can also use induction. Let's first consider the base case, n = 1. We have a1 = √2 < 3, so the sequence is bounded above by 3 for n = 1. Now, let's assume that the sequence is bounded above by 3 for n = k, so ak < 3. Then, for n = k+1, we have ak+1 = √2 + ak < √2 + 3 = 3.2 < 3, so the sequence is also bounded above by 3 for n = k+1. Therefore, by induction, the sequence is bounded above by 3 for all n ≥ 1.

(c) By the Monotonic Sequence Theorem, if a sequence is both monotonically increasing and bounded above, then the limit of the sequence exists. Since we have shown that the sequence is monotonically increasing in part (a) and bounded above by 3 in part (b), we can conclude that the limit of the sequence exists.

(d) To find the limit of the sequence, we can use the fact that an+1 = √2 + an for all n ≥ 1. Taking the limit of both sides as n approaches infinity, we get limn→∞ an+1 = limn→∞ √2 + an. Since the limit of the sequence exists, we can write this as L = √2 + L, where L is the limit of the sequence. Solving for L, we get L = 2, so the limit of the sequence is 2.

(e) To determine whether the series X∞ n=1 an is convergent, we can use the fact that the limit of the sequence is 2. Since the sequence converges to 2, the terms of the sequence are getting closer and closer to 2 as n approaches infinity. This means that the terms of the series are getting smaller and smaller, and the series is convergent.

The number of sodas sold is 83 and the number of hot dogs sold is 52.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

Let's call the number of sodas sold "x".

According to the problem, the number of hot dogs sold is 31 less than the number of sodas sold, so we can write the number of hot dogs sold as "x - 31".

We also know that the combined total of sodas and hot dogs sold is 135, so we can write an equation:

x + (x - 31) = 135

Simplifying this equation:

2x - 31 = 135

Adding 31 to both sides:

2x = 166

Dividing both sides by 2:

x = 83

So the number of sodas sold is 83.

To find the number of hot dogs sold, we can use the equation we came up with earlier:

x - 31 = 83 - 31 = 52

So the number of hot dogs sold is 52.

Therefore, the number of sodas sold is 83 and the number of hot dogs sold is 52.

Answer: 75 inches

Step-by-step explanation:

Using Pythagorean's Theorem, a² + b² = c², let a represent the length of the bed.

a² + 40² = 85²

a² + 1600 = 7225

a² = 5625

a = 75

The length of the bed is 75 inches.

Hope this helps!

Answer: 75

Step-by-step explanation: We can think of Aubrey’s bed as a triangle, Since the area doesn't matter. The base would be width (40) and the hypotenuse (length from corners) would be 85. So, since A^2+B^2=C^2 and c is 85 and a is 40. The equation is 40^2+?^2=85^2 so if we solve the numbers whit exponents we would get this: 1600+?=7225. Then we would just subtract 1600 from 7225 which is: 5625. Now we are not done. 5625 is just the square version of 5625. So we would need to find the square root. Which is 75.

The vector x = [2, -3, 1] is a basis for Row(A)⊥. This means that any vector in Row(A)⊥ can be written as a multiple of x.

To find a basis for Row(A)⊥ using the dot product, we need to find a vector that is orthogonal to all the rows of A. This means that the dot product of the vector and each row of A should be equal to 0.

Let's say the vector we are looking for is x = [x1, x2, x3]. Then we need to solve the following system of equations:

x1 * 1 + x2 * 4 + x3 * 2 = 0
x1 * 2 + x2 * 2 + x3 * 1 = 0
x1 * 3 + x2 * 1 + x3 * 1 = 0

We can write this system of equations in matrix form as:

[1 4 2] [x1] = [0]
[2 2 1] [x2] = [0]
[3 1 1] [x3] = [0]

We can use Gaussian elimination to solve this system of equations. After performing the necessary row operations, we get:

[1 0 -2] [x1] = [0]
[0 1  3] [x2] = [0]
[0 0  0] [x3] = [0]

From the last equation, we can see that x3 can be any value. Let's choose x3 = 1. Then, from the second equation, we get x2 = -3, and from the first equation, we get x1 = 2.

So, the vector x = [2, -3, 1] is a basis for Row(A)⊥. This means that any vector in Row(A)⊥ can be written as a multiple of x.

The probability that the sample proportion is between 0.26 and 0.44 is 0.9998, or 99.98%.

The probability that the sample proportion is between 0.26 and 0.44 can be found using the normal distribution formula.

First, we need to find the mean and standard deviation of the sample proportion. The mean of the sample proportion is equal to the population proportion, which is 0.37. The standard deviation of the sample proportion can be found using the formula:

σ = √(p(1-p)/n)

Where p is the population proportion, and n is the sample size. Plugging in the given values, we get:

σ = √(0.37(1-0.37)/245) = 0.0196

Next, we need to find the z-scores for the given sample proportions. The z-score can be found using the formula:

z = (x - μ)/σ

Where x is the sample proportion, μ is the mean of the sample proportion, and σ is the standard deviation of the sample proportion. Plugging in the values for the lower bound of the sample proportion (0.26), we get:

z = (0.26 - 0.37)/0.0196 = -5.61

Similarly, for the upper bound of the sample proportion (0.44), we get:

z = (0.44 - 0.37)/0.0196 = 3.57

Now, we can use the standard normal table to find the probabilities corresponding to these z-scores. The probability for z = -5.61 is 0, and the probability for z = 3.57 is 0.9998.

Finally, to find the probability that the sample proportion is between 0.26 and 0.44, we subtract the lower probability from the upper probability:

P(0.26 < p < 0.44) = 0.9998 - 0 = 0.9998

Therefore, the probability that the sample proportion is between 0.26 and 0.44 is 0.9998, or 99.98%.

Answer:

Step-by-step explanation:

Let's assume that the number of child tickets sold is x and the number of adult tickets sold is y.

From the problem statement, we know that:

The total number of tickets sold is 412, so x + y = 412.

The total amount of money collected from selling these tickets is 2,725.50, so 3x + 7.50y = 2,725.50.

We can use these two equations to solve for x and y. One way to do this is to use substitution:

Solve the first equation for x: x = 412 - y.

Substitute this expression for x into the second equation: 3(412 - y) + 7.50y = 2,725.50.

Simplify and solve for y: 1,236 - 3y + 7.50y = 2,725.50, so 4.50y = 1,489.50, and y = 330.

Use the first equation to find x: x = 412 - y, so x = 82.

Therefore, Kell High School sold 82 child tickets and 330 adult tickets.

Step-by-step explanation:

50 pizzas can be sold in 10 hours, according to this equation p = 5h.

In mathematics, an equation is a statement that asserts the equality of two expressions. An equation typically consists of two expressions separated by an equal sign (=). The expression on the left side of the equal sign is usually called the "left-hand side" (LHS) of the equation, while the expression on the right side of the equal sign is called the "right-hand side" (RHS) of the equation.

Let's use the variable p to represent the number of pizzas sold, and the variable h to represent the number of hours it takes to sell those pizzas. We can use the formula for finding the rate of sales (also known as the unit rate) to write an equation that represents the situation:

rate = amount of sales ÷ time

In this case, we know that 35 pizzas are sold in 7 hours. So, the rate of sales is:

rate = 35 pizzas ÷ 7 hours

Simplifying this expression, we get:

rate = 5 pizzas per hour

Therefore, the equation that represents the situation is:

p = 5h

This equation tells us that the number of pizzas sold (p) is equal to 5 times the number of hours it takes to sell those pizzas (h). For example, if we want to know how many pizzas can be sold in 10 hours, we can plug in h = 10 and solve for p:

p = 5h

p = 5(10)

p = 50

Therefore, 50 pizzas can be sold in 10 hours, according to this equation p = 5h

Step-by-step explanation:

Lets find the slope of the line first so we can write the equation.

Counting the slope, we can see the slope of the line is [tex]\frac{3}{1}[/tex] or 3, so we have to write the equation of the line in slope intercept form [tex]y=mx+b[/tex] where m is the slope and b is the y intercept.

We know that the y intercept is -4 by looking at the graph, so we simply plug in our slope and y intercept.

[tex]y=3x-4[/tex]

To tell if equations are parallel or perpendicular:

Parallel:  The slope is the same

Perpendicular: The slope is the opposite reciprocal

Lets look at the equations and see if there parallel:

1. [tex]y=-3x+10[/tex] is neither.

2. The equation of the line is in point slope form, however we are already given the slope in the equation. The slope is [tex]-\frac{1}{3}[/tex], which is the opposite reciprocal of 3, therefore it is perpendicular.

3. [tex]\frac{1}{3}[/tex] is not the opposite reciprocal of 3, it is neither.

4. The equation of the line is in standard form, which means we must solve for y to get it in slope intercept form

[tex]-3x+y=1[/tex]
Subtract -3x on both sides

[tex]y=1-(-3x)[/tex]

Simplify

[tex]y=3x+1[/tex]

The equation has the same slope, so it is parallel.

For the first set of fractions, the inequality symbol would be <, as 8/9 is less than 10/12. The rationale for this is that when fractions have different denominators, the fraction with the smaller denominator is always less. For the second set of fractions, the inequality symbol would be >, as -5/6 is greater than -6/8. The rationale for this is that when two fractions have the same denominator, the fraction with the larger numerator is always greater.

For n≥2, the corresponding recursive function is f (1) =3f(n)=f(n1) +5.

In mathematics, a function is a rule that pairs each element from the domain with exactly one from the range or codomain of two sets.

In a recursive function, the output value at a certain input value is defined as a function of the output value at the previous input value. In this instance, we may use the definition to derive the recursive function from the explicit function:

f (n) = 5n - 2 f (n) = 5n - 3 f (n) = 5(2) - 8 f (n) = 5(3) - 13

The right response is: A. When n=2, f(1) = 2f(n)= f(n1) + 5.

As a result, the recursive function can be written as: f (1) =3f(n)=f(n1) +5 for n2.

The value of the triple integral is 49π ln(49) - 24.5π.

To evaluate this triple integral using cylindrical coordinates, we need to express the limits of integration in terms of cylindrical coordinates. We can convert the Cartesian coordinates to cylindrical coordinates as follows:

x = r cos(θ)

y = r sin(θ)

z = z

The region of integration is a cylinder centered at the origin with radius 7 and height 14 (from -7 to 7 in the y-direction). Therefore, the limits of integration are:

0 ≤ r ≤ 7

0 ≤ θ ≤ 2π

-7 ≤ z ≤ 7

Substituting these limits of integration and the Cartesian-to-cylindrical conversion into the integral, we get:

∫∫∫ 7 −7 (49 - [tex]y^2 - r^2[/tex]) / ([tex]x^2 + y^2)[/tex] dz dx dy

= ∫[tex]0^7[/tex]∫[tex]0^2π[/tex] ∫-7^7 (49 - [tex]r^2[/tex]sin^2(θ) - r^2) / (r^2cos^2(θ) + r^2sin^2(θ)) dz r dθ dr

= ∫0^7 ∫0^2π [ln|49-r^2|] from -7 to 7 dθ dr

= ∫0^7 2π ln|49-r^2| dr

This integral is now a single-variable integral that can be evaluated using integration by substitution or by parts. Let u = 49 - r^2 and du = -2r dr. Then:

∫0^7 2π[tex]ln|49-r^2|[/tex] dr = ∫49^0 -πln|u| du/-2

Answer:

The distributive property is used when finding the product of two polynomials by distributing one polynomial to each term of the other polynomial. For example, if we wanted to multiply (3x - 4)(2x + 5), we would use the distributive property by first multiplying 3x(-4) and 2x(5) and then adding the results together.

Polynomials are closed under multiplication, meaning that when two polynomials are multiplied together, the result is always another polynomial. This is true because a polynomial is a combination of constants and variables raised to non-negative integer powers, and when two polynomials are multiplied, the result is a combination of constants and variables raised to non-negative integer powers, which is a polynomial.

Therefore , the solution of the given problem of slope comes out to be slope-intercept equation y = 2x + 1.

The y-intersection axis's with the slope of the line marks the inflection point in arithmetic where the y-axis intersects a line or curve. Y = mx+c, where m stands for the slope and c for the y-intercept, is the equation for the long line. The y-intercept (b) and slope (m) of the line are emphasised in the equation intercept form. An solution with the intersecting form (y=mx+b) has m and b as the slope and y-intercept, respectively.

Here,

Y = mx + b, where m is the line's slope and b is the y-intercept, is the slope-intercept version of a linear equation. Given two points (x1, y1) and (x2, y2), we can use the following method to determine the slope of the line:

=> m = (y2 - y1) / (x2 - x1) (x2 - x1)

For instance, if the two locations (2, 5) and (4, 9) are provided, we can determine the slope as follows:

=> m = (9 - 5) / (4 - 2) = 2

The y-intercept can then be determined by using one of the locations and the slope. Let's use points 2 and 5:

=> y = mx + b

=> 5 = 2(2) + b

=> 5 = 4 + b

=> b = 1

As a result, the line going through the points (2, 5) and (4, 9) has the slope-intercept equation y = 2x + 1.

The final answer is 3

The calculation you are looking to solve is 2.2 + (3)/(5). To solve this, we first need to convert the improper number 2.2 to a fraction. We can do this by multiplying the whole number by the denominator of the fraction and then adding the numerator. In this case, we would multiply 2 by 5 and then add 2, giving us 12/5. Now, we can add this fraction to the other fraction:

12/5 + 3/5 = 15/5

Next, we can simplify the fraction by dividing both the numerator and denominator by the greatest common factor. In this case, the greatest common factor is 5, so we can divide both the numerator and denominator by 5:

15/5 = 3

Therefore, the final answer is 3.

In summary, 2.2 + (3)/(5) = 3.

Th expression for total price of the supplies is $ 12.91 .

Any mathematical statement with variables, numbers, and an arithmetic operation between them is called an expression or an algebraic expression. For instance, the expression 4m + 5 has the terms 4m and 5 as well as the variable m of the supplied expression, all of which are separated by the arithmetic sign +.

Anything that is variable, or without a fixed value, is a variable. Alphabetic characters like a, b, c, m, n, p, x, y, z, and so on are typically used to denote expression variables. By combining several variables and numbers, we can create a wide range of expressions.

Given : price of nails, n = $1.29/b

           price of washers, w = $0.79/b

           price of bolts, b = $2.39/b

He bought 2 pounds of nails, 4 pounds of washers, and 3 pounds of bolts.

So, The total supplies will be :

= $1.29/b × 2 + $0.79/b × 4 + $2.39/b × 3

= 2.58 + 3.16 + 7.17

= $ 12.91

The probability of fraudulent applications are:

The given parameters are

n = 25

p = 0.12

The individual probability can be calculated as

P(x) = C(n, x) * p^x * (1 - p)^(n - x)

So, we have

Probability the number of fraudulent applications in the sample is 0

P(0) = C(25, 0) * 0.12^0 * (1 - 0.12)^(25 - 0)

P(0) = 0.0410

Probability the number of fraudulent applications in the sample is 3

P(3) = C(25, 3) * 0.12^3 * (1 - 0.12)^(25 - 3)

P(3) = 0.2387

Probability the number of fraudulent applications in the sample is 3 or less

P(x ≤ 3) = P(0) + ... P(3)

Using the formula above, we have

P(x ≤ 3) = 0.4088

Probability the number of fraudulent applications in the sample is 5 or more

P(x ≥ 5) = P(5) + ... P(25)

Using the formula above, we have

P(x ≥ 5) = 0.1734

Probability the number of fraudulent applications in the sample is more than 3

P(x > 3) = 1 - P(x ≤ 3)

By substitution, we have

P(x > 3) = 1 - 0.4088

P(x > 3) = 0.5912
