Answer:

C) fails to consider that commuting trips may cause significantly more than 20 percent of the traffic congestion

Step-by-step explanation:

The correct option is - C) fails to consider that commuting trips may cause significantly more than 20 percent of the traffic congestion

Reason -

Option A is incorrect because the statistics can not be incorrect.

Option B is incorrect because they are not talking about the city.

Option C is correct because Urban rail reduces congestion.

Option D is incorrect because the opposers cited the example of one city and the supporters are presenting evidence in the case of that city itself.

Option E is incorrect because they are providing an explanation for why the commuters data given by opposers is not relevant. The opposers talked about commuters.

The gradient of the equation y=2x+3 is 2.

The Gradient (also called Slope) of a line shows how steep it is.

The gradient of a function is defined to be a vector field. Generally, the gradient of a function can be found by applying the vector operator to the scalar function. (∇f (x, y)). This kind of vector field is known as the gradient vector field.

Given equation: y = 2x + 3

y = mx + c

2x - y = -3

x/ -3/2 + y/3 = 1

Comparing both the equation we get,

m=2 (slope) and c=3(intercept)

So the gradient is 2.

Cot θ is equal to 1/2.

To find cot θ, we need to use the given information:

csc θ = √(5/2)

tan θ = 0

We can use the reciprocal identities and the Pythagorean identity to find cot θ.

Reciprocal Identity:

csc θ = 1/sin θ

Pythagorean Identity:

\(sin^2\) θ + \(cos^2\)θ = 1

Given that csc θ = √(5/2), we can find sin θ:

1/sin θ = √(5/2)

sin θ = 2/√5

Using the Pythagorean identity, we can find cos θ:

\(sin^2\) θ + \(cos^2\) θ = 1

\((2/√5)^2\)+ \(cos^2\) θ = 1

4/5 + \(cos^2\) θ = 1

\(cos^2\) θ = 1 - 4/5

\(cos^2\)θ = 1/5

cos θ = ±√(1/5)

Now, we can find cot θ:

cot θ = cos θ / sin θ

Since tan θ = 0, it means that sin θ is not equal to 0, as tan θ = sin θ / cos θ. Therefore, we can use the positive value of cos θ.

cot θ = (√(1/5)) / (2/√5)

cot θ = (√5/√5) / (2/√5)

cot θ = 1/2

Therefore, cot θ is equal to 1/2.

Answer:

179 minutes

Step-by-step explanation:

From the information given, you know that the total cost of the long distance service is equal to 7 plus the result of multiplying 0.7 for the number of minutes:

Total cost=7+0.07x, where x is the amount of minutes.

Now, you can replace the total cost with 19.53 that is the amount Ali was billed and solve for x:

19.53=7+0.07x

19.53-7=0.07x

12.53=0.07x

x=12.53/0.07

x=179

According to this, the answer is that Ali was billed for 179 minutes.

The balance A for P dollars invested at a rate r for t years and compounded n times per year can be calculated using the formula: A = P (1 + r/n)^(n*t)

where:

P = the principal amount (initial investment)

r = the annual interest rate (as a decimal)

t = the number of years the money is invested

n = the number of times the interest is compounded per year

A = the total amount including principal and interest

To solve for the balance A, simply substitute the given values for P, r, t, and n into the formula and evaluate:

For example, let's say we invest $5000 at an annual interest rate of 4.5% for 3 years, compounded monthly (n=12).

P = $5000

r = 0.045 (4.5% expressed as a decimal)

t = 3 years

n = 12 (compounded monthly)

A = 5000 (1 + 0.045/12)^(12*3)

= 5000 (1.00375)^36

= $5,838.27

Therefore, balance A is $5,838.27 after 3 years of investing $5000 at an annual interest rate of 4.5%, compounded monthly.

To determine which function increases faster, we have to find the ratio = \(\frac{\triangle y}{\triangle x}\).

Rate of Change:

A rate of change describes how an output quantity changes relative to the change in the input quantity. The units on a rate of change are “output units per input units.”

The average rate of change between two input values is the total change of the function values (output values) divided by the change in the input values.

\(\frac{\triangle y}{\triangle x} = \frac{f(x_{2})-f(x_{1}) }{x_{2}-x_{1}}\)

How to determine:

Given the value of a function at different points, calculate the average rate of change of a function for the interval between two values \(x_{1}\) and \(x_{2}\).

Hence the answer is to determine which function increases faster, we have to find the ratio = \(\frac{\triangle y}{\triangle x}\).

The rate at which the average revenue is changing at x = 177 (the quantity of belts produced and sold) is approximately -0.0345.

To discover the rate at which the average income is changing, we ought to differentiate the income function and after that assess it at the given amount of belts.

The income work is given as:

R(x) = 65x^(9/10)

To discover the normal income, we partition the whole income by the amount of belts delivered and sold. So, the normal income work, AR(x), is:

AR(x) = R(x) / x = (65x^(9/10)) / x = 65x^(-1/10)

To discover the rate at which normal income is changing, we got to separate the normal income work, AR(x), with regard to x.

d/dx [AR(x)] = d/dx [65x^(-1/10)]

Utilizing the control run the show of separation, ready to rework this as:

d/dx [AR(x)] = -1/10 * 65x^(-1/10 - 1) = -6.5x^(-11/10)

Presently, we will assess the subordinate at x = 177 (the amount of belts delivered and sold) to discover the rate at which normal income is changing:

d/dx [AR(x)] = -6.5(177)^(-11/10)

Step-by-step explanation:

woman must pick up at least 43 balls to be sure she is holding at least 33 blue balls.we can use the Pigeonhole Principle.

A) In order for the woman to be sure she is holding at least 33 balls of the same color, we need to find the minimum number of balls she must pick up such that there are at least 33 balls of each color.

Since there are 10 red balls and 10 blue balls, we can pick up 32 balls without getting 33 of the same color. However, if we pick up one more ball (33rd ball), it must be the same color as one of the previous 32 balls, either red or blue.

Therefore, the woman must pick up at least 33 balls to be sure she is holding at least 33 balls of the same color.

B) In order for the woman to be sure she is holding at least 33 blue balls, we need to find the minimum number of balls she must pick up such that there are at least 33 blue balls.

If the woman is lucky, she could pick up 32 balls without getting 33 blue balls. However, if she picks up 33 balls, the worst-case scenario is that she picks up all the red balls and only 10 blue balls.

The cost to border the outside of the mural using 1-centimeter square tiles is 600 dollars.

The area of Rectangle is length times of width.

We have been given that a rectangular mural has a length of 90 centimeters and a width of 30 centimeters less than its length.

Length = 90 cm

Width = 90 - 30 = 60 cm

The formula to calculate the perimeter of a rectangle,

Perimeter = 2(length + breadth)

Perimeter = 2(90 + 60)

Perimeter = 2(150)

Perimeter = 300

Therefore, the cost to border the outside of the mural using 1-centimeter square tiles costs $2 each.

= 300 x 2
