-12 ÷ 4 = -3

If the derivative f'(x) is positive, increasing, concave down Then the function f(x) is increasing, concave down.

If the derivative f'(x) is positive, increasing, and concave down, it implies the following characteristics about the function f(x):

=Since the derivative f'(x) is positive, it indicates that the function f(x) is increasing.

This means that as x increases, the values of f(x) also increase.

The concavity of the function is determined by the second derivative f''(x). In this case, since f'(x) is increasing and concave down, it suggests that the second derivative f''(x) is negative.

A negative second derivative indicates a concave down shape for the function.

1. To expand the logarithm using the properties of logarithms, we have:

log(x°y-1) = log(x^y/y)log(x°y-1) = log(x^y) - log(y)log(x°y-1) = ylog(x) - log(y)

Therefore, log(x°y-1) can be rewritten as ylog(x) - log(y).2. To evaluate the expression without using a calculator, we have:

log(64) / log(2) + 3log(4) = 6log(64) / log(2) + log(4^3) = 6log(2^6) / log(2) + 3log(2^2)

= 6(6) / 1 + 3(2)

= 36 + 6

= 42

Therefore, log(64) / log(2) + 3log(4) = 42.3.

To solve e^(2x) – e^x – 72 = 0, we can substitute y = e^x to obtain y^2 – y – 72 = 0(y – 9)(y + 8) = 0Therefore, y = 9 or y = -8Substituting back to obtain x:When y = 9, e^x = 9, so x = ln(9)When y = -8, e^x = -8, which is not possible Therefore, x = ln(9).4. To find the height of a mountain with an atmospheric pressure of 8.544 pounds per square inch, we can substitute P = 8.544 into the formula P = 14.7e^(-0.21x) to obtain:8.544 = 14.7e^(-0.21x)ln(8.544 / 14.7) = -0.21xln(8.544 / 14.7) / -0.21 = x Therefore, x is approximately 16,515 feet, so the mountain is approximately 16,515 feet high.5. To find the exponential model representing the amount of lodine-125 remaining in the tumor after t days, we can use the formula A(t) = A0(1 – r)^t, where A0 is the initial amount of lodine-125 and r is the decay rate expressed as a decimal. Since 1.15% = 0.0115, we have:A(t) = 0.8(1 – 0.0115)^tA(t) = 0.8(0.9885)^t To find the amount of lodine-125 remaining after 60 days, we substitute t = 60 into the formula to obtain:A(60) = 0.8(0.9885)^60A(60) ≈ 0.447 grams.

Therefore, the amount of lodine-125 remaining after 60 days is approximately 0.447 grams.6. To find the magnitude of the second earthquake, we use the fact that the energy of an earthquake is proportional to 10^(1.5M), where M is the magnitude on the Richter Scale. Since the second earthquake has 700 times as much energy as the first, we have:

10^(1.5M2) / 10^(1.5M1)

= 70010^(1.5M2 – 1.5M1)

= 700log(10^(1.5M2 – 1.5M1))

= log(700)1.5M2 – 1.5M1

= log(700)M2 – M1

= log(700) / 1.5M2

= M1 + log(700) / 1.5

Since the first earthquake has magnitude 3.9 on the MMS, we have:M2 = 3.9 + log(700) / 1.5M2 ≈ 5.46Therefore, the magnitude of the second earthquake is approximately 5.46 (rounded to the hundredth).

In the case of F = 5, the resulting value of C = -15 indicates that it is a very cold temperature in Celsius.

To convert degrees Fahrenheit (F) to degrees Celsius (C), you can use the formula C = (5/9) * (F - 32). Let's apply this formula to find C for F = 5.

Substituting the given values into the formula, we have:

C = (5/9) * (5 - 32)

  = (5/9) * (-27)  [subtracting 32 from 5]

  = -135/9

  = -15

Therefore, when F = 5, the equivalent temperature in degrees Celsius is -15.

The formula for converting Fahrenheit to Celsius is derived from the relationship between the two temperature scales. In this formula, 32 represents the freezing point of water in Fahrenheit, and 5/9 is the conversion factor to adjust for the different scale intervals between Fahrenheit and Celsius.

By subtracting 32 from the Fahrenheit temperature and then multiplying it by 5/9, we account for the temperature offset and convert it to the Celsius scale.

The resulting value represents the temperature in degrees Celsius.

The area of the minor sector is 33.33 cm^2 and the area of minor segment is 53.27 cm^2.

A chord of a circle is a straight line segment that connects any two points on the circumference of the circle.

The area of the major sector can be found by using the formula:

Area of major sector = (Angle of sector / 360) * π * r^2

Where the angle of sector is 120°, and the radius of the circle is 10cm.

So the area of the major sector = (120/360) * π * (10 cm)^2 = (1/3) * π * 100 cm^2 = 33.33 cm^2

To find the area of the minor segment, we need to find the area of the minor sector and then subtract it from the area of the triangle formed by the center of the circle, the midpoint of the chord, and the endpoint of the chord.

The area of the minor segment = area of the triangle - area of the minor sector

As the angle subtended by the chord is 120°, the minor sector will subtend an angle of (360-120) = 240°.

So the area of the minor sector = (120/360) * π * (10 cm)^2 = (2/3) * π * 100 cm^2 = 33.33 cm^2

The area of the triangle can be found by using the formula:

Area of the triangle = (1/2) * b * h

Where b is the distance between the center of the circle and the midpoint of the chord and h is the length of the altitude drawn from the center of the circle to the chord.

So the area of the minor segment = (1/2) * (10cm) * (10cm) * sin(120/2) -33.33 cm^2 = 50*sqrt(3) - 33.33 cm^2=53.27 cm^2

Therefore, the area of the minor sector is 33.33 cm^2 and the area of minor segment is 53.27 cm^2.

The limits of integration for the volume calculation will be x = -5 to x = 5. The volume of the solid is 2000/3.

To find the volume of the solid, we need to integrate the area of each cross section perpendicular to the x-axis.

The base of the solid is the circle with equation x^2 + y^2 = 25, which has a radius of 5. Since the cross sections perpendicular to the x-axis are squares, the side length of each square will be equal to 2 times the y-coordinate of the circle.

To determine the limits of integration, we need to find the x-values where the circle intersects the x-axis. Solving the equation x^2 + y^2 = 25 for y = 0, we have:

x^2 + 0^2 = 25

x^2 = 25

x = ±5

Therefore, the limits of integration for the volume calculation will be x = -5 to x = 5.

Now, let's set up the integral to find the volume:

V = ∫[from -5 to 5] (side length)^2 dx

The side length of each square is 2y, so we need to express y in terms of x using the equation of the circle.

x^2 + y^2 = 25

y^2 = 25 - x^2

y = ±√(25 - x^2)

Since the cross sections are squares, we only need to consider the positive square root. Therefore, the side length of each square is 2√(25 - x^2).

Now we can rewrite the volume integral:

V = ∫[from -5 to 5] (2√(25 - x^2))^2 dx

V = 4 ∫[from -5 to 5] (25 - x^2) dx

Expanding the integrand:

V = 4 ∫[from -5 to 5] (25 - x^2) dx

= 4 ∫[from -5 to 5] (25) dx - 4 ∫[from -5 to 5] (x^2) dx

The integral of a constant is simply the constant times the interval:

V = 4 (25x)∣[from -5 to 5] - 4 ∫[from -5 to 5] (x^2) dx

Evaluating the first term:

V = 4 (25(5) - 25(-5)) - 4 ∫[from -5 to 5] (x^2) dx

= 4 (125 + 125) - 4 ∫[from -5 to 5] (x^2) dx

= 4 (250) - 4 ∫[from -5 to 5] (x^2) dx

Now we need to evaluate the integral of x^2:

V = 4 (250) - 4 (∫[from -5 to 5] (x^2) dx)

= 4 (250) - 4 [(x^3/3)∣[from -5 to 5]]

= 4 (250) - 4 [(5^3/3) - (-5^3/3)]

= 4 (250) - 4 [(125/3) - (-125/3)]

= 4 (250) - 4 [(250/3)]

= 4 (250) - (4/3)(250)

= (1000) - (1000/3)

= 3000/3 - 1000/3

= 2000/3

Therefore, the volume of the solid is 2000/3.

A data set's attributes are enumerated through descriptive statistics. You can use inferential statistics to test a hypothesis or determine whether your data can be applied to a larger population.

Descriptive statistics concentrate on describing the features of a dataset that are readily evident (a population or sample). In contrast, inferential statistics concentrate on drawing conclusions or generalisations from a sample of data in a larger dataset.

The information from a research sample is described and condensed using descriptive statistics. We can draw conclusions about the larger population from which we drew our sample using inferential statistics.

The area of statistics known as descriptive statistics is focused on providing a description of the population being studied. A type of statistics known as inferential statistics concentrates on inferring information about the population from sample analysis and observation.

Referring to Table 3.1, if the government imposes a price of $3, a shortage will result.

To determine the outcome when the government imposes a price of $3, we need to compare the quantity demanded and quantity supplied at this price level.
According to Table 3.1, at a price of $3, the quantity demanded is 30 units, while the quantity supplied is 40 units. The quantity demanded (30 units) is less than the quantity supplied (40 units), resulting in a situation known as a shortage.
A shortage occurs when the quantity demanded exceeds the quantity supplied at a given price. In this case, a shortage of 10 units occurs because consumers are willing to buy more than what producers are offering at the price of $3.
