Answer:

slope = 0

Step-by-step explanation:

calculate the slope m using the slope formula

m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)

with (x₁, y₁ ) = (- 2, 4 ) and (x₂, y₂ ) = (3, 4 )

m = \(\frac{4-4}{3-(-2)}\) = \(\frac{0}{3+2}\) = \(\frac{0}{5}\) = 0

Answer:

slope or m=0

y=-4

Step-by-step explanation:

Use slope formula.

\(\frac{y2-y1}{x2-x1}\)

\(\frac{4-4}{3+4}=\frac{0}{12}\)

This means that slope or m=0

Then use points slope formula.

y-y1=m(x-x1)

y-4=0(x-4)

y-4=0

Add 4 to both sides.

y=-4

Statement (C) The graph show a reflection and the pre-image and image are congruent is the correct option.

We can see that both the figures are identical but the vertices A and C have changed the position.

This shows that it is a reflection of the image given originally as the vertices have only being flipped.

Now, we can also see that the shape and size both are same of the image and the pre-image. Also, the sides of the triangle are equal to one another.

The angles are also equal to one another.

This means that they are congruent to each other.

The total surface area of the cylinder with a radius of 7 cm and height of 22 cm in terms of pi is 406π cm².

A cylinder is simply a 3-dimensional shape having two parallel circular bases joined by a curved surface.

The total surface area of a cylinder is expressed as;

Total surface area = 2πrh + 2πr²

Where r is radius of the circular base, h is height and π is constant pi ( π = 3.14 )

Given that:

Height of the cylinder h = 22 cm

Radius of the cylinder r = 7 cm

Total surface area = ?

Plug the given values into the above formula and solve for the total surface area.

Total surface area = 2πrh + 2πr²

Total surface area = ( 2 × π × 7 × 22 ) + ( 2 × π × 7² )

Total surface area = 308π + 98π

Total surface area = 406π cm²

Therefore, the total surface area is 406π cm².

The required, expression -7 + 24i with the form a + bi, we can see that the value of b is 24.

To find the value of b in the expression (3 + 4i)^2, we can simply expand the expression and identify the coefficient of the imaginary part.

(3 + 4i)² = (3 + 4i)(3 + 4i)

Using the FOIL method, we can multiply the terms:

= 3 * 3 + 3 * 4i + 4i * 3 + 4i * 4i

= 9 + 12i + 12i + 16i²

Since i² is defined as -1, we can substitute it:

= 9 + 12i + 12i - 16

= -7 + 24i

Comparing the expression -7 + 24i with the form a + bi, we can see that the value of b is 24.

Answer:

r = 0 and r = -8

Step-by-step explanation:

|-4-r|=4

-4 = -4-r = 4

0 = - r = 8

0 = r = -8

When you have absolute value signs, to get rid of the absolute value signs and find the value of the term, you simply add another eqaul sign (=), and add a negative in front (- =). If it is already set to equal a negative, there isn't any solution.

|x| = 4

-4 = x = 4

So x would equal 4 and -4 for this example.

Another example:

|x|=-5

Because it's equal to a negative, the solution is automatically no solution.

The actual answer is r = 0 and r = -8

The product of 56.2 and 9.2057 to the appropriate number of significant digits is 517.00.

The significant digits in a number are the digits that contribute to its precision. When multiplying numbers, the result should be rounded to the same number of significant digits as the factor with the least number of significant digits.

In this case, 56.2 has three significant digits, and 9.2057 has five significant digits. The factor with the least number of significant digits is 56.2. Therefore, the product should be rounded to three significant digits.

Multiplying 56.2 by 9.2057 gives 517.38134. Rounding this result to three significant digits gives us 517.00. The trailing zeros after the decimal point are significant in this case as they indicate the precision of the result. Hence, the correct answer is 517.00.

The pirate has gone into debt by $38,979 in base 10 due to his encounter with Captain Rusczyk.

To determine the amount of debt, we need to calculate the difference between the value of the goods the pirate stole and the amount demanded by Captain Rusczyk. The pirate initially stole $2345_6, which means it is in base 6. Converting this to base 10, we have $2\times6^3 + 3\times6^2 + 4\times6^1 + 5\times6^0 = 2\times216 + 3\times36 + 4\times6 + 5\times1 = 432 + 108 + 24 + 5 = 569$.

Captain Rusczyk demanded $41324_5, which means it is in base 5. Converting this to base 10, we have $4\times5^4 + 1\times5^3 + 3\times5^2 + 2\times5^1 + 4\times5^0 = 4\times625 + 1\times125 + 3\times25 + 2\times5 + 4\times1 = 2500 + 125 + 75 + 10 + 4 = 2714$.

Therefore, the pirate has gone into debt by $569 - 2714 = -2145$. Since the pirate owes money, we consider it as a negative value, so the pirate has gone into debt by $38,979 in base 10.

The numerical value "62" is a statistic because it is based on the sample of passengers aboard the Hindenburg airship.

In the given scenario, the numerical value is "62." We are told that there were 97 passengers aboard the Hindenburg airship and that 62 of them survived its explosion.

Since the numerical value is based on the sample (i.e., the passengers aboard the Hindenburg airship), it is a statistic. It describes the proportion of passengers who survived the explosion in the sample.

If we wanted to know the proportion of passengers who survived the explosion in the entire population (i.e., all passengers who have ever traveled on the Hindenburg airship), we would need to determine the parameter.

The factor that determines whether to use a z-score or a t statistic for a hypothesis test is the sample size.

When the sample size is small (less than 30), a t statistic should be used. When the sample size is large (greater than or equal to 30), a z-score should be used.

The reason for this is that when the sample size is small, the sample standard deviation is less reliable as an estimate of the population standard deviation.

As a result, the t distribution, which accounts for this uncertainty, is used instead of the standard normal distribution, which assumes that the population standard deviation is known.

However, when the sample size is large, the sample standard deviation is more reliable as an estimate of the population standard deviation.

As a result, the standard normal distribution can be used instead of the t distribution. This simplifies calculations and makes the z-score more appropriate.

Answer: -8.93

Step-by-step explanation:

Given the function:

N(X) = 90(0.86)^x+ 69

X in the interval [0, 6]

For X = 0

N(0) = 90(0.86)^0 + 69

90 + 69 = 159

For X = 6

N(6) = 90(0.86)^6 + 69

90(0.404567235136) + 69

= 105.41105116224

Therefore, average change of change in temperature ;

(temp 2 - temp 1) / ( time 2 - time)

(105.41105116224 - 159) / (6 - 0)

= - 53.58894883776 / 6

The  approximate average rate of change of the temperature of the hot chocolate, in  degrees per minute, over the interval [0, 6] is;

Option 1; -8.93

We are given the function;

N(x) = 90(0.86)ˣ + 69

We want to find the average rate of change over the interval (0, 6).

Thus;

N(0) = 90(0.86)⁰ + 69

N(0) = 90 + 69

N(0) = 159°

N(6) = 90(0.86)⁶ + 69

N(6) = 105.411°

Formula for rate of change is;

Rate of change = Δy/Δx

Thus; Rate of change = (159 - 105.411)/(0 - 6)
