Answer:

4

Step-by-step explanation:

2+2=4

Answer:

4 is the answer to 2+2 when we add the numbers

Point (4,0) and (0,7) (C) were passed through by the line equation of 7x1 + 4x2 = 28.

From the case, we know that:

Line equation: 7x1 + 4x2 = 28

Passed through points?

To answer this question, we can try to find some conditions:

First, we will try to find the valuf f x2 if x1 = 0:

(x1 = 0)

7(0) + 4.x2 = 28

0 + 4.x2 = 28

4.x2 = 28

x2 = 7 --> (0,7)

Next, we try if x2=0, then x1 = ...

(x2 = 0)

7x1 + 4(0) = 28

7x1 = 28

x1 = 4 --> (4,0)

Step-by-step explanation:

The wheels of the tricycle are turning approximately 7.68 revolutions per second.

To convert the speed from feet per hour to revolutions per second, we need to know the circumference of the wheels. The circumference of a circle with radius 5 inches is 2 * pi * 5 = 10 * pi inches. To convert the speed from feet per hour to inches per second, we multiply by 12, since there are 12 inches in 1 foot. So, the speed in inches per second is 20 * 12 = 240 inches per second. The number of revolutions per second is then equal to the speed divided by the circumference:

240 inches per second / (10 * pi inches) = 240 / (10 * pi) revolutions per second

Rounding to the nearest hundredth:

240 / (10 * pi) ≈ 24 / (pi) ≈ 7.68 revolutions per second

So, the wheels are turning approximately 7.68 revolutions per second.

Answer:

The area of the original garden is x^2 square feet.

The lengths of the sides of the new garden are x + 2 feet and x + 7 feet.

The area of the new garden, in square feet, is

\((x + 2)(x + 7)\)

\( {x}^{2} + 9x + 14\)

1) the area of his garden is, x² feet²

2) the lengths of the sides of the new garden are,

⇒ (x + 2)

⇒ (x + 7)

And, the area of the new garden is,

Area = x² + 9x + 14

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

Farmer Bob has a small square garden that is x feet by x feet.

Now,

We know that;

Area of square = Side²

Here, Side = x feet

Hence, the area of his garden is,

Area = x × x

Area = x² feet²

Now, When He decides to add 2 feet to one side of the garden and 7 feet to the other side.

Then, the lengths of the sides of the new garden are,

⇒ (x + 2)

⇒ (x + 7)

Hence, the area of the new garden is,

Area = (x + 2) (x + 7)

Area = x² + 2x + 7x + 14

Area = x² + 9x + 14

Thus, 1) the area of his garden is, x² feet²

2) the lengths of the sides of the new garden are,

⇒ (x + 2)

⇒ (x + 7)

And, the area of the new garden is,

Area = x² + 9x + 14

The number of possible values for n is infinite since the logarithm function is continuous and can take on any positive real value.

In this case, the lengths of the sides of the triangle are given as logarithms of different numbers. The logarithm function is continuous and defined for all positive real numbers. It maps each positive real number to a unique value on the logarithmic scale.

Since the lengths of the sides are given as logarithms, it means that the actual lengths of the sides can be any positive real numbers corresponding to those logarithmic values. Therefore, there are infinitely many possible values for n, as the logarithm function can take on any positive real value.

The expressions for dz/du and dz/dv are as follows:

dz/du = 4x siny

dz/dv = -6y cosx

To find the expressions for dz/du and dz/dv, we need to differentiate the given function z = 2x^2 - 3y with respect to u and v, respectively.

1. dz/du:

Since u = x^2 siny, we can express z in terms of u by substituting x^2 siny for u in the original function:

z = 2u - 3y

Now, we differentiate z with respect to u while treating y as a constant:

dz/du = d/dx (2u - 3y)

      = 2(d/dx (x^2 siny)) - 0 (since y is constant)

      = 2(2x siny)

      = 4x siny

Therefore, dz/du = 4x siny.

2. dz/dv:

Similarly, we express z in terms of v by substituting 2y cosx for v in the original function:

z = 2x^2 - 3v

Now, we differentiate z with respect to v while treating x as a constant:

dz/dv = d/dy (2x^2 - 3v)

      = 0 (since x^2 is constant) - 3(d/dy (2y cosx))

      = -6y cosx

Therefore, dz/dv = -6y cosx.

In summary, the expressions for dz/du and dz/dv are dz/du = 4x siny and dz/dv = -6y cosx, respectively.

To determine which weight is more extreme relative to their respective groups, we compare the z-scores of a male weighing 1500 g and a female weighing 205 g. The weight with the higher absolute z-score is considered more extreme.

To compare the weights, we calculate the z-scores for both the male and the female weights. The z-score measures how many standard deviations a data point is away from the mean. The formula for calculating the z-score is (x - μ) / σ, where x is the data point, μ is the mean, and σ is the standard deviation.

For the male weighing 1500 g:

z_male = (1500 - 3234.8) / 758.7 = -1.92

For the female weighing 205 g:

z_female = (205 - 3075.6) / 576.0 = -4.09

Comparing the absolute values of the z-scores, we find that |z_female| = 4.09 > |z_male| = 1.92.

Since the absolute value of the z-score for the female weight is larger, the female weight of 205 g is more extreme relative to the group from which it came. This indicates that the female weight is significantly lower compared to the mean weight of newborn females, while the male weight of 1500 g is relatively closer to the mean weight of newborn males.

Answer:

a. Let's call the average ticket price for Dallas in 2005 as "d" and the average ticket price for Boston in 2005 as "b". Then the system of equations can be written as:

y_d = d + 0.53x (where y_d represents the price of an average ticket for Dallas after x years)

y_b = b - 1.08x (where y_b represents the price of an average ticket for Boston after x years)

b. To find the number of years in which the average ticket price for Dallas will approximately equal that of Boston, we need to solve the equation y_d = y_b for x. Plugging in the equations for y_d and y_b, we get:

d + 0.53x = b - 1.08x

Rearranging and solving for x, we have:

1.61x = b - d

x = (b - d) / 1.61

Now we just need to plug in the values for d and b from the table:

d = 53.60

b = 55.93

x = (55.93 - 53.60) / 1.61 = 2.33 years

So it will take approximately 2.33 years for the average ticket price for Dallas to approximately equal that of Boston.

Step-by-step explanation:

Answer: a. Let x be the number of years after 2005, and y be the price of an average ticket. Then, we can write the following system of equations to represent the information in the table:

For Dallas:

y = 53.60 + 0.53x

For Boston:

y = 55.93 - 1.08x

This system of equations represents the average ticket price y for Dallas and Boston as a function of the number of years x after 2005, with the change in price from the 2004 season to the 2005 season given in the table.

b. To find the number of years when the average ticket price for Dallas will approximately equal that of Boston, we can set the two equations equal to each other and solve for x:

53.60 + 0.53x = 55.93 - 1.08x

2.33x = 2.33

x = 1

So, the average ticket price for Dallas and Boston will approximately equal each other after 1 year. Therefore, in 2006, the average ticket price for Dallas will approximately equal that of Boston.

The boundaries of the class 1.87-3.43 are D) 1.865-3.435. The lower boundary is 1.865 and the upper boundary is 3.435.

The boundaries of the class 1.87-3.43 can be determined by subtracting and adding half of the smallest possible unit of measurement to the given class limits. In this case, since the given class limits are 1.87 and 3.43, we need to find the boundaries by subtracting and adding half of the smallest possible unit of measurement.

Let's assume the smallest possible unit of measurement is 0.01.

To find the lower boundary:

Lower Boundary = Lower Limit - (0.01/2)

Lower Boundary = 1.87 - 0.005

Lower Boundary = 1.865

To find the upper boundary:

Upper Boundary = Upper Limit + (0.01/2)

Upper Boundary = 3.43 + 0.005

Upper Boundary = 3.435

Therefore, the boundaries of the class 1.87-3.43 are:
