find the scale factor of the smaller figure to the larger figure
Therefore, the scale factor of the smaller polygon to the larger polygon is 2. Therefore, the scale factor of the smaller triangle to the larger triangle is 6.
What is scale factor?Scale factor refers to the ratio of any two corresponding lengths in two similar geometric figures. In other words, it is the ratio of the size of an object in one image or figure to the size of the same object in another image or figure, assuming that the two images or figures are proportional to each other. The scale factor can be used to determine the relationship between the sizes of the objects in the two figures or images.
Here,
1. The scale factor from the smaller polygon to the larger polygon is found by dividing the length of the larger polygon by the length of the smaller polygon:
scale factor = length of larger polygon / length of smaller polygon
scale factor = 14 / 7
= 2
2. The scale factor from the smaller triangle to the larger triangle is found by dividing the length of the larger triangle by the length of the smaller triangle:
scale factor = length of larger triangle / length of smaller triangle
scale factor = 24 / 4
= 6

Find the equation of the ellipse
The equation of the ellipse whose vertices are at (-3, -7), and (-3, 5), and focus is at (-3, 1) is; [tex]\frac{(x + 3}{8}+\frac{(y -2}{9} = 1[/tex]
What is standard form of the equation of an ellipse?The equation of an ellipse can be presented as follows;
[tex]\frac{(x - h)^2}{b^2} + \frac{(y-k)^2}{a^2} = 1[/tex]
Where;
(h, k) = The coordinates of the center of the ellipse
a = The semi major axis
b = The semi minor axis
(h, k ± a) = The vertex coordinates
(h ± b, k) = The covertex coordinates
(h, k ± c) = The coordinates of the foci
c² = a² - b²
The vertex of the specified ellipse are; (-3, -1) and (-3, 5)
The focus = (-3, 1)
Therefore;
h = -3k + a = 5
k - a = -1
2·k = 4
k = 4/2 = 2
k = 2k + a = 5
2 + a = 5
a = 5 - 2 = 3
a = 3k - c = 1
2 - c = 1
-c = 1 - 2 = -1
-c = -1
c = 1
c² = a² - b²
Therefore;
1² = 3² - b²
b² = 3² - 1² = 8
b² = 8The equation of the ellipse is therefore;

4. A study by the Technology Services department revealed company employees receive
an average of two emails per hour. Assume the arrival of these emails is approximated
by the Poisson distribution. What is the probability that an employee received 5 or more
emails during the same period?
She received 5 or more emails in the same time period with a probability of 0.05265.
What is probability?Simply put, probability is the likelihood that something will occur.
When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes.
Statistics is the study of events that follow a probability distribution.
The higher the likelihood, the more likely it is that the event will take place.
So, the probability would be:
We know that λ = 2.
The formula for the poisson distribution states:
P(x = x) = (λˣ * e^⁻ˣ) / x!
P(x = 1) = (2¹ *e⁻²) / 1!
P(x = 1) = (2 * 0.1353352) = 0.2706
Then,
P(x ≥ 5) = 1 - P(x < 5)
1 - P(x < 5) = 1 - [p(x = 0) + p(x = 1) + p(x = 2) + p(x = 3) + p(x = 4)]
We gather the individual probabilities and combine them. We can use a Poisson distribution calculator to speed up computations:
1 - P(x < 5) = 1 - (0.13534+0.27067+0.27067+0.18045+0.09022)
1 - P(x < 5) = 1 - 0.94735 = 0.05265
P(x ≥ 5) = 1 - P(x < 5) = 0.05265

Nancy and George (?? relationship) form EB Corporation with the following investments: cash by Nancy of $ ; land by George (basis of $ and fair market value of $ ). EB Corporation issues …. shares of stock,....... each to Nancy and George. Thus, each receives stock in EB worth $. Which of the following statements is correct? [Hints: about section 351?]
The correct statement is that the transfer of land by George to the corporation in exchange for stock should qualify for non-recognition of gain or loss under section 351 of the IRC, and each shareholder's basis in the stock received would depend on their respective contributions.
What is fair market value and stocks?Fair market value is the amount that a product would sell for on the open market if all parties were acting in their own best interests, were not subject to excessive pressure, and were given a reasonable amount of time to complete the transaction (FMV).
The given scenario describes the formation of a corporation by Nancy and George, where Nancy contributes cash and George contributes land. The corporation issues shares of stock to Nancy and George in exchange for their respective contributions.
Section 351 of the Internal Revenue Code (IRC) provides rules for the non-recognition of gain or loss on the transfer of property to a corporation in exchange for its stock. To qualify for non-recognition, certain requirements must be met, including that the transfer must be made in exchange for stock, and the transferors must be in control of the corporation immediately after the exchange.
Assuming that the requirements of section 351 are met, the transfer of the land by George to the corporation in exchange for stock should not result in any immediate tax consequences. George's basis in the stock received would be equal to his basis in the land transferred. Nancy's contribution of cash would not affect her basis in the stock received.
Therefore, the correct statement is that the transfer of land by George to the corporation in exchange for stock should qualify for non-recognition of gain or loss under section 351 of the IRC, and each shareholder's basis in the stock received would depend on their respective contributions.

The three sides of a triangular fence have lengths 4x + 5, y − 7, and 3x − 2. What is the total perimeter?
A) 7x + y + 10 feet
B) 7x + y − 4 feet
C) 7x + y feet
D) 4x + y − 4 feet
The correct option is (b) i.e. the total perimeter of the fence is 7x + y − 4 feet.
What is Perimeter?
Perimeter is the total length of the boundary or outer edge of a two-dimensional shape, such as a polygon, circle, or ellipse. It is the sum of the lengths of all the sides or arcs that make up the shape. For example, the perimeter of a square is the sum of the lengths of all its sides, while the perimeter of a circle is the circumference, which is the distance around the circle. The perimeter is often measured in units such as centimeters, meters, or feet, depending on the context of the problem.
Given : sides of the fence
s₁ = 4x + 5
s₂ = y − 7
s₃ = 3x − 2
We know that, perimeter of a triangle is sum of all three sides.
So, Perimeter of the fence = s₁+ s₂+ s₃
= 4x + 5 + y − 7 + 3x − 2

Answer:
Step-by-step explanation:
I'm sorry, but I cannot accurately calculate the driver's average speed without additional information such as the distance traveled and the time taken.
However, I can help you calculate the cost of fuel if the driver fills up half of the tank's capacity:
Half of the tank's capacity is 28/2 = 14 litres.
The cost of fuel per litre is R17.98.
Therefore, the cost of filling up half the tank is 14 x R17.98 = R251.72.
So, if the price of fuel is R17.98 per litre and the driver fills up half the tank, they will pay R251.72 for fuel.

Answer:
To get 9d^2 + 6d + 1 from (3d+1), you would need to multiply by 3d+1 again.
Expanding (3d+1)(3d+1), you get:
9d^2 + 3d + 3d + 1
Simplifying, you get:
9d^2 + 6d + 1
Therefore, you need to multiply (3d+1) by (3d+1) or (3d+1)^2 to get 9d^2 + 6d + 1.

The statement that could be true for g is D. g(-13) = 20.
What statement could be true?
We are given that the function g has a domain of -20 ≤ x ≤ 5 and a range of -5 ≤ g(x) ≤ 45, and we also know that g(0) = -2 and g(-9) = 6.
We can use this information to eliminate the statements that are not true and find the one that could be true for g.
A. g(-4) = -11: Since the range of g(x) is between -5 and 45, and g(-4) is less than -5, this statement cannot be true.B. g(0) = 2: We are given that g(0) = -2, so this statement is not true.C. g(7) = -1: 7 is outside the domain of g(x), so we cannot determine the value of g(7).D. g(-13) = 20: Since g(-9) = 6 and the range of g(x) is between -5 and 45, we can see that g(x) increases as x decreases.Therefore, g(-13) is greater than g(-9) and could be 20, so this statement could be true.

The statement " If a and x are positive numbers and a ≠ 1, then[tex]log_a(x^r) = r * log_a(x)[/tex] for any real number r" is true .
Why is the above statement true?To prove the equation, we can start with the definition of logarithms:

Using this definition, we can rewrite both sides of the equation as exponents:

[tex]r * log_a(x) = y[/tex] if and only [tex]a^y = x^r[/tex]
Since [tex]a^y = x^r[/tex] in both case, we have:

The solution of the quadratic equation x² + 10x -4 found using the quadratic formula is: x = -5 ± √29.
Explain about the quadratic formula?Sometimes, factoring the quadratic, setting its factor equal to zero, but then solving each factor is the quickest way to find the answer to "ax² + bx + c = 0" given the value of x.
Yet, there are situations when the quadratic is too complicated, it just doesn't factor in anyway, or you might not feel like factoring at all. The Quadratic Formula also can provide the solutions for you even when factoring sometimes isn't going to be successful.
The given equation:
x² + 10x -4
The general quadratic equation can be written as:
ax² + bx +c
Then, roots of the equation can be found using quadratic formula:
x = -b±√(b²-4ac))/(2a)
a = 1, b = 10 and c = -4
Put the values:
x = [ -10 ± √(10²- 4*1*(-4))]/ (2*1)
x = [ -10 ± √(100 + 16)]/ 2
x = [-10 ± √116] / 2
x = [-10 ± 2√29] / 2

Tabi's credit card bill is $283.93. This includes her charges and interest. If the new charges are $213.95 more than the interest, find the amount in charges and the amount in interest.
Tabi's bill includes $248.94 in charges and $34.99 in interest.
Let x be the amount of interest that Tabi was charged, in dollars.
According to the problem, the new charges are $213.95 more than the interest, so the amount of new charges is x + $213.95.
The total bill, which includes the charges and interest, is $283.93.
Therefore, we can write an equation:
x + (x + $213.95) = $283.93
Simplifying and solving for x, we get:
2x + $213.95 = $283.93
2x = $69.98
x = $34.99
So the amount of interest charged is $34.99.
To find the amount of charges, we can use the equation for new charges:
x + $213.95 = $34.99 + $213.95 = $248.94
So the amount of charges is $248.94.
