The surface area of the rectangular prism is 18 sq cm greater than the surface area of the cube.

Here, we are given a rectangular prism and a cube as shown in the figure below.

The three sides of the prism are- 2, 3 and 6

Thus, the total surface area of the cube will be-

2 [(2*3) + (3*6) + (6*2)]

= 2[6 + 18 + 12]

= 2*36

= 72 cm square

Now, the side of the cube is 3 cm

Thus, the total surface area of the cube will be-

6( 3*3 )

= 6*9

= 54 cm square

Thus, the difference between the surface area of prism and cube is = 72 - 54

= 18 cm square.

Thus, the surface area of the rectangular prism is 18 sq cm greater than the surface area of the cube.

The probability that either house sales or interest rates will increase in the next 6 months is estimated to be 0.79.

To find the probability that either house sales or interest rates will go up in the next 6 months, we can use the concept of union in probability theory. The union of two events A and B, denoted as A ∪ B, represents the event that either A or B or both occur.

Given the probabilities that house sales will increase (0.25) and interest rates on housing loans will go up (0.74), we need to calculate the probability of the union of these two events. However, we must consider that the events are not mutually exclusive, meaning that it is possible for both house sales to increase and interest rates to go up simultaneously.

To calculate the probability of the union, we can use the formula: P(A ∪ B) = P(A) + P(B) - P(A ∩ B), where P(A) represents the probability of event A, P(B) represents the probability of event B, and P(A ∩ B) represents the probability of both events A and B occurring.

Substituting the given probabilities into the formula, we have P(A ∪ B) = 0.25 + 0.74 - P(A ∩ B). Since we do not have the information regarding the joint probability of both events occurring (P(A ∩ B)), we cannot determine the exact probability of the union. However, we can say that the probability of either house sales or interest rates going up is estimated to be 0.79, assuming that the joint probability is not significant.

According to the lecture, the term that refers to an unequal distribution of rewards between men and women, reflecting their different positions in a social hierarchy, is gender inequality.

Gender inequality is a concept that highlights the disparities and imbalances in the treatment, opportunities, and rewards experienced by individuals based on their gender. It acknowledges that women and men occupy different positions in social, economic, and political structures, leading to unequal distribution of resources, power, and privileges. In the context of the lecture, gender inequality specifically refers to the differential allocation of rewards, such as income, career opportunities, education, and social status, between men and women.

This unequal distribution of rewards can manifest in various forms, including gender pay gaps, limited access to leadership positions, underrepresentation of women in decision-making roles, and societal interest and stereotypes that perpetuate gender-based discrimination.

Mr. Red's speed was 10 yards per second when he ran from the 0 line to the finish line, which was a distance of 40 yards.

To find Mr. Red's speed, we need to use the formula

speed = distance ÷ time

We know that Mr. Red ran from the 0 line to the finish line, which is a distance of 40 yards. We also know that he did this in 4 seconds. So, we can plug these values into the formula

speed = 40 yards ÷ 4 seconds

Simplifying, we get

speed = 10 yards per second

Answer:

p = 1.4

Step-by-step explanation:

The ratio of sides is the same

p/4.2 = 1.7/5.1

multiply both sides by 4.2

p = 1.7/5.1 * 4.2

p = 1.4

===========================================================

Explanation:

JK = LM because opposite sides of a parallelogram are the same length.

Side LM is p units long, where p is a placeholder for a number.

To determine what number replaces p, we can form the proportion shown below

BC/KL = CD/LM

Refer to the drawing below. I've circled the corresponding pieces. Note the color coding. Other equations are possible.

-----------

So,

BC/KL = CD/LM

(5.1)/(1.7) = (4.2)/p

5.1p = 1.7*4.2 ....................... cross multiply

5.1p = 7.14

p = (7.14)/(5.1)

p = 1.4

The largest base Abigail can cut from the square piece of wood is a circle with a radius of 2.25 inches.

Since the piece of wood is square and has a width of 4.5 inches, each side of the square is also 4.5 inches. The largest circle that can be cut from a square is one where the diagonal of the square is equal to the diameter of the circle. The diagonal of a square can be found using the Pythagorean theorem, which states that the square of the hypotenuse (diagonal) is equal to the sum of the squares of the other two sides. In this case, the diagonal is the same as the side length of the square, which is 4.5 inches.

Using the Pythagorean theorem, we can find the length of the diagonal (d) as follows:

d^2 = 4.5^2 + 4.5^2

d^2 = 20.25 + 20.25

d^2 = 40.5

Taking the square root of both sides, we get:

d ≈ √40.5 ≈ 6.36

Since the diameter of the circle is equal to the diagonal of the square, the radius is half the diameter. Therefore, the radius of the largest base Abigail can cut from the wood is approximately 6.36 / 2 = 3.18 inches. However, since the width of the wood is 4.5 inches, the largest base she can cut has a radius of 2.25 inches, which is half the width of the wood.

The exponential form of the equation log_r (u) = p is r^p = u.

The exponential form of the equation log(z) = r is z = e^r.

In mathematics, logarithms and exponentials are inverse operations. The logarithm of a number is the exponent to which another fixed value, the base, must be raised to produce that number. In contrast, the exponential function raises the base to a power, which gives us a certain value.

When we are given an equation in logarithmic form, we can convert it into exponential form by using the inverse operation of logarithms. For instance, in the equation log_r (u) = p, the base is r, the exponent is p, and the value is u. Therefore, the exponential form of this equation is r^p = u.

Similarly, for the equation log(z) = r, the base is assumed to be 10. Therefore, we can write the exponential form of this equation as z = 10^r. However, when we use the natural logarithm, we can write the equation as z = e^r.

In conclusion, converting logarithmic equations into exponential form and vice versa is a useful technique in mathematics.

The region obtained by revolving the area below the graph of the function f(x) = a, where a > 1, and above the z-axis about the z-axis does not have finite volume.

To determine whether the region has finite volume, we need to consider the behavior of the function f(x). Since f(x) = a for x > 1, the function is a horizontal line with a constant value of a. When this region is revolved about the z-axis, it creates a solid with a circular cross-section.

The volume of a solid obtained by revolving a region with a known finite volume can be calculated using integration. However, in this case, the function f(x) is a horizontal line with a constant value, which means the cross-section of the resulting solid is also a cylinder with an infinite height.

A cylinder with an infinite height has an infinite volume. Therefore, the region obtained by revolving the area below the graph of f and above the z-axis about the z-axis does not have finite volume. It extends indefinitely along the z-axis, making it impossible to calculate a finite volume for this region.

C. \((-\infty\text{, }2]\)

Step-by-step explanation:

An arrow on a function means "goes to infinity". Of course, that infinite is in the direction the arrow is pointed at.
Here, we can see that the arrow points to the left. That means it goes to infinity in the left direction. Since all of the x values to the left of the y axis are negative, the function goes to minus infinity, but is not equal to it.

In addition, we can see that the function "stops" at the point (2, 4). Since the point's circle is not hollow, that point is included in the domain. Now, since we're asking for the domain, we'll be looking to take the x value of that point, which is x = 2.

Therefore, the domain is \((-\infty\text{, }2]\)

The equation holds for all n, we've proved by strong induction that the formula an = (1 + 3n)(-1)^n is correct for all n ≥ 0.

Based on the given recurrence relation, we can start computing the first few terms of the sequence:

a0 = 1

a1 = -2

a2 = -2a1 - a0 = -2(-2) - 1 = 3

a3 = -2a2 - a1 = -2(3) - (-2) = -8

a4 = -2a3 - a2 = -2(-8) - 3 = 19

a5 = -2a4 - a3 = -2(19) - (-8) = -30

...

From these calculations, it's difficult to spot a pattern or function that describes the sequence, so we'll use strong induction to prove a general formula for the nth term.

First, let's assume that the formula for an is of the form an = A(1)⋅r1n + A(2)⋅r2n, where A(1) and A(2) are constants to be determined, and r1 and r2 are the roots of the characteristic equation r2 + 2r + 1 = 0, which is obtained by substituting an = r^n into the recurrence relation and solving for r.

Factoring the quadratic equation, we get (r+1)^2 = 0, so r = -1 is a repeated root. This means that the general solution is of the form an = (A + Bn)(-1)^n, where A and B are constants determined by the initial conditions a0 = 1 and a1 = -2.

To find A and B, we use the initial conditions:

a0 = 1 = A + B(0)(-1)^0 = A

a1 = -2 = A + B(1)(-1)^1 = A - B

Solving for A and B, we get A = 1 and B = 3. Therefore, the formula for the nth term is:

an = (1 + 3n)(-1)^n

Now we need to prove that this formula holds for all n ≥ 0. We'll use strong induction and assume that the formula holds for all k < n. Then we'll show that it holds for n as well.

Substituting the formula into the recurrence relation, we get:

an = -2an-1 - an-2

(1 + 3n)(-1)^n = -2(1 + 3(n-1))(-1)^(n-1) - (1 + 3(n-2))(-1)^(n-2)

Simplifying this equation, we get:

(-1)^n = (-1)^n

Since the equation holds for all n, we've proved by strong induction that the formula an = (1 + 3n)(-1)^n is correct for all n ≥ 0.

Division is a basic procedure in which an integer is divided. It's best to imagine of it as a number of things being distributed among a particular number of persons, such as in the previous example. In mathematics, division is the process of dividing a number into equal parts and determining how many equal parts can be made. For instance, dividing 15 by 3 implies dividing 15 into three equal groups of five. Dividend Divisor = Quotient + Remainder is the formula for dividing two numbers. The dividend is the number that is being divided in this case. The divisor is the number, which divides the number (dividend) into equal parts.

Here,

37 - 21 and 1/4 = 36 and 4/4 - 21 and 1/4 = 15 and 3/4 = 63/4

63/4 divided by 1 and 3/4 = 63/4  divided by 7/4 = 63/4 * 4/7 = 9 years

To find the number of days it will take for Juliana's investment to grow, we can use the formula for simple interest

I = P * r * t.

I = interest earned
P = principal amount (initial investment)
r = interest rate per year (in decimal form)
t = time in years In this case,

Juliana's principal amount (P) is $3,300, the interest rate (r) is 6.25% or 0.0625, and she wants to reach $3,450. We need to solve for t. $3,450 = $3,300 * 0.0625 * t Divide both sides of the equation by ($3,300 * 0.0625) to isolate t:
t = $3,450 / ($3,300 * 0.0625)
t = 17 So it will take Juliana approximately 17 days for her investment to grow to $3,450.
