The correct equation is,
⇒ (5 - 6i) (2 + 4i)
Let us assume that;
⇒ (a + bi) (c + di)
⇒ ac + adi + bci + bdi²
⇒ (ac − bd) + (ad + bc)i
Matching coefficients:
30 < ac − bd < 80
ad + bc = 0
Hence, We need to pick four integers between -9 and 9 such that these two equations are satisfied. One possible combination is:
a = 8, b = -4, c = 6, d = 3
The number would be:
ac − bd = (8)(6) − (-4)(3) = 60
Puzzle 2
Using the result from Puzzle 1:
ac − bd = 34
ad + bc = 8
Like before, it makes sense to assume b is negative. With some trial and error, one possible answer is:
a = 5, b = -6, c = 2, d = 4
Thus, The correct equation is,
⇒ (5 - 6i) (2 + 4i)

Find the probability of at least one failure in five trials of a binomial experiment in which the probability of success is %30
Answers
The probability of having at least one failure in five trials is approximately 0.83193 or 83.193%.
To calculate the probability of at least one failure, we first need to find the probability of having zero failures in five trials, which is equal to (0.3)^5 or 0.00243. Then, we subtract this value from 1 to obtain the probability of having at least one failure. This is because the sum of the probabilities of all possible outcomes should be equal to 1.
In this case, we can see that the probability of having at least one failure in five trials is quite high, at approximately 83%. This means that it is more likely than not that there will be at least one failure in a series of five trials with a success rate of 30%.
The probability of having at least one failure in five trials of a binomial experiment with a success rate of 30% can be calculated as follows:
1 - (probability of having zero failures in five trials)
= 1 - (0.7)^5
= 1 - 0.16807
= 0.83193
Therefore, the probability of having at least one failure in five trials is approximately 0.83193 or 83.193%.

19. The triangle with sides 3, 4, 6 is obtuse triangle.
20. The triangle with sides 9, 11, 16 is acute triangle.
How to Classify Triangles?In a triangle, the sum of the squares of the two shorter sides must be greater than the square of the longest side for the triangle to be considered "non-degenerate," which means it is a valid triangle with a positive area.
19. We have sides of 3, 4, and 6. We can check whether this triangle is non-degenerate using the above formula:
3² + 4² = 9 + 16 = 25, which is less than 6² = 36.
Therefore, this triangle is non-degenerate and we can classify it based on the size of its angles.
To do so, we can use the Pythagorean Theorem to find that the longest side (6) is opposite the largest angle, which is obtuse. Therefore, triangle #19 is an obtuse triangle.
20. For triangle #20, we have sides of 9, 11, and 16. Checking again with the above formula:
9² + 11² = 81 + 121 = 202, which is less than 16² = 256. So this triangle is also non-degenerate.
Using the same method as before, we can find that the longest side (16) is opposite the largest angle, which is acute. Therefore, triangle #20 is an acute triangle.

(the radius of the line of latitude through Y
(Take t=2 and R=6406 km)
Answers
The radius of the line of latitude through X is approximately 5729 km, and the latitude of Y is approximately 43°.
Let X be the starting town with coordinates (28°N, 66°E), and let Y be the destination town which is 3900 km due South of X. We want to find the radius of the line of latitude through X, and the latitude of Y.
First, we can find the distance between X and Y using the Pythagorean theorem. The distance due South is 3900 km, and the distance due East is 28° × R, where R is the radius of the Earth. Using t=2 and R=6406 km, we have:
distance due East = 28° × 6406 km × cos(66°) ≈ 2055.6 km
distance between X and Y = sqrt((3900 km)^2 + (2055.6 km)^2) ≈ 4498.6 km
Next, we can find the latitude of Y using the formula:
latitude of Y = 90° - arctan(distance due South / radius of the Earth)
Using t=2 and R=6406 km, we have:
latitude of Y = 90° - arctan(3900 km / 6406 km) ≈ 43°
Finally, we can find the radius of the line of latitude through X using the formula:
radius of line of latitude = radius of the Earth * cos(latitude of X)
Using the coordinates of X, we have:
latitude of X = 28°N
radius of line of latitude = 6406 km * cos(28°) ≈ 5729 km

. If you cut a sector out of a circle and fold the radiitogether, you can form a cone. What is the measure of angle ABCsuch that the sector will produce a cone with maximum possiblevolume?
Answers
The measure of angle ABC that will produce a cone with the maximum possible volume can be found using optimization techniques. Let r be the radius of the circle and x be the length of the radius that is cut out to form the cone. Then, the slant height of the cone can be expressed as s = sqrt(r^2 - x^2), and the volume of the cone can be expressed as V = (1/3)πx^2(r - x).To find the maximum volume, we take the derivative of V with respect to x and set it equal to zero:dV/dx = (2/3)πx(r - 2x) = 0Solving for x, we get x = r/2, which is the value that maximizes the volume of the cone. Therefore, the sector that will produce a cone with the maximum possible volume is formed by cutting a radius that is half the length of the radius of the circle. The measure of angle ABC can be found using trigonometry, as sin(ABC) = x/r = 1/2, so ABC = sin^(-1)(1/2) ≈ 30 degrees.

#SPJ11
The measure of angle ABC that will produce a cone with the maximum possible volume is approximately 58.49 degrees.
To determine the measure of angle ABC that will produce a cone with the maximum possible volume, we need to use some geometry formulas.
First, we need to understand that the volume of a cone is given by the formula V = (1/3)πr^2h, where r is the radius of the base and h is the height of the cone.
When we fold the sector of the circle to form a cone, we need to make sure that the radius of the base of the cone is equal to the length of the arc of the sector. Let's call this length x.
Now, we know that the circumference of the circle is 2πr, and the length of the arc of the sector is x. Therefore, the measure of the angle of the sector is (x/2πr) * 360 degrees.
We want to find the measure of angle ABC that will give us the maximum possible volume of the cone. To do this, we need to maximize the value of r and h.
Using some trigonometry, we can see that sin(ABC/2) = (x/2r). Rearranging this formula, we get r = x/(2sin(ABC/2)).
Substituting this value of r in the formula for the volume of the cone, we get V = (1/3)π(x^2/(4sin^2(ABC/2)))h.
To maximize this volume, we need to maximize both x and h. We know that x is fixed, so we need to maximize h.
Using some more trigonometry, we can see that h = rcos(ABC/2) = (x/2) * cot(ABC/2).
Substituting this value of h in the formula for the volume of the cone, we get V = (1/3)π(x^2/(4sin^2(ABC/2)))((x/2) * cot(ABC/2)).
To find the maximum value of V, we need to differentiate this formula with respect to ABC and set the derivative equal to zero.
After some calculations, we get tan(ABC/2) = 2/3. Solving for ABC, we get ABC = 2tan^-1(2/3) ≈ 58.49 degrees.
Therefore, the measure of angle ABC that will produce a cone with the maximum possible volume is approximately 58.49 degrees.

or spoiled food in it. The probability that a crate has bruised or spoiled food in it is 0.11. What
is the probability that he will reject a shipment of 15 crates?
Answers
The probability of finding 0, 1, 2, or 3 bruised or spoiled crates in a shipment of 15 crates is:
P(X = 0) = (15 choose 0) * (0.11)^0 * (0.89)^15 = 0.27
P(X = 1) = (15 choose 1) * (0.11)^1 * (0.89)^14 = 0.39
P(X = 2) = (15 choose 2) * (0.11)^2 * (0.89)^13 = 0.25
P(X = 3) = (15 choose 3) * (0.11)^3 * (0.89)^12 = 0.09
The probability of finding more than 3 bruised or spoiled crates is:
P(X > 3) = 1 - P(X ≤ 3) = 1 - (P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3))
= 1 - (0.27 + 0.39 + 0.25 + 0.09) = 0.01
Therefore, the probability that the restaurant owner will reject a shipment of 15 crates is 0.01 or 1%.

Step-by-step explanation:
You want the perimeter of a shape bounded by 4 semicircles of radius 10 cm and two straight lines 10 cm long.
PerimeterThe circumference of a circle with radius 10 cm is ...
C = 2πr
C = 2(3.142)(10 cm) = 62.84 cm
The shape is bounded (in part) by 4 semicircles, so 2 full circles. The length of the curved boundary is ...
curve length = 2 · (62.84 cm) = 125.68 cm
The two straight edges at either end of the figure are equal in length to the radius. That total length gets added to the curve length to form the perimeter.
P = straight length + curve length
P = 2·10 cm + 125.68 cm ≈ 145.7 cm
The perimeter is about 145.7 cm.

Barry is selling baseball cards. he sold 2 for $8.00 and 4 for $14.00. what will barry charge for 7 baseball cards if he keeps selling cards at the same rate?
Answers
Barry will charge $24.50 for 7 baseball cards if he keeps selling cards at the same rate.
We can solve this problem by first calculating the price per card for each of the two deals, and then using that information to find the price for 7 cards.
Let x be the price of one baseball card, in dollars. From the information given, we know that:
2 cards cost $8.00, so 1 card costs $4.00: 2x = 8.00 => x = 4.00
4 cards cost $14.00, so 1 card costs $3.50: 4x = 14.00 => x = 3.50
So we see that the price per card is different for the two deals. To find the price for 7 cards, we can use a weighted average of the two prices:
Price for 2 cards: $8.00
Price for 4 cards: $14.00
Total price for 6 cards: $22.00
We can now find the price for one more card by subtracting the total price for 6 cards from the price for 7 cards:
Price for 7 cards: $?
Price for 6 cards: $22.00
Price for 1 card: $?
Price for 7 cards = Price for 6 cards + Price for 1 card
Price for 1 card = Price for 7 cards - Price for 6 cards
We know that the total price for 7 cards is the same as the price for 2 cards plus the price for 4 cards plus the price for 1 more card:
Price for 7 cards = Price for 2 cards + Price for 4 cards + Price for 1 card
Price for 7 cards = 2x + 4x + 1x = 7x
Substituting the value we found for x earlier, we get:
Price for 1 card: $3.50
Price for 7 cards: $24.50
Therefore, Barry will charge $24.50 for 7 baseball cards if he keeps selling cards at the same rate.

Answers
The vertex will be at (0, -3), and the graph will be lower than the parent function by 3 units at every point. The parent function of the absolute value function is f(x) = |x|.
To shift this function 3 units down, we need to subtract 3 from the function's output (y) at every point on the graph. This can be expressed as:
f(x) = |x| - 3
The absolute value function is symmetric around the y-axis, which means that any shifts to the left or right do not affect the shape of the graph, only its position on the coordinate plane.
However, a vertical shift up or down will change the location of the vertex, the point where the graph changes direction. In this case, the vertex will be at (0, -3), and the graph will be lower than the parent function by 3 units at every point.

a norman window is a window with a semicircle on top of a regular rectangular window as shown in the diagram.what should the dimensions of the rectangular part of the norman window be to allow in as much light as possible if there is only 12 ft of framing material available
Answers
Answer: The dimensions of the rectangular part of the Norman window that would allow in as much light as possible, given 12 feet of framing material available, are approximately 4 feet by 8 feet.
Explanation:
Let's assume that the height of the rectangular part of the Norman window is "h" and the width is "w". Then the diameter of the semicircle is also "w". The total amount of framing material needed is the sum of the perimeter of the rectangular part and half the circumference of the semicircle:
Perimeter of rectangular part = 2h + 2w
Circumference of semicircle = 1/2πw
Total framing material = 2h + 2w + 1/2πw
We want to maximize the amount of light entering the window, which is proportional to the area of the rectangular part of the window. The area of the rectangular part is given by:
Area of rectangular part = hw
Now we can use the constraint that there is only 12 feet of framing material available:
2h + 2w + 1/2πw = 12
Solving for h in terms of w:
h = (12 - 2w - 1/2πw)/2
Substituting this expression for h into the formula for the area of the rectangular part:
Area of rectangular part = w(12 - 2w - 1/2πw)/2
We can now use calculus to find the value of w that maximizes this area. Taking the derivative of the area with respect to w and setting it equal to zero:
d/dw[w(12 - 2w - 1/2πw)/2] = 0
Simplifying and solving for w:
w = 4π/(4 + π)
Substituting this value of w into the expression for h:
h = (12 - 2w - 1/2πw)/2
h ≈ 8
Therefore, the dimensions of the rectangular part of the Norman window that allow in as much light as possible, given 12 feet of framing material available, are approximately 4 feet by 8 feet.

We want to find out how many jujubes equal the weight of one marble, so we need to eliminate all the other variables except for j and m. We can do this by using substitution and algebraic manipulation.
First, we can solve the second equation for s in terms of c:
7s = 5c
s = (5/7)c
Then, we can substitute this expression for s in the first equation:
5m = 3s
5m = 3(5/7)c
m = (3/7)c
Next, we can solve the third equation for c in terms of j:
3c = 14j
c = (14/3)j
Now we can substitute this expression for c in the previous equation:
m = (3/7)c
m = (3/7)(14/3)j
m = 2j
So we have found that one marble is equal in weight to 2 jujubes. But the question asks for the weight of one marble in terms of jujubes, not in terms of jujubes and toy soldiers and plush chipmunks. We can use the other equations to eliminate the other variables:
5m = 3s
5m = 3(5/7)c
5m = (15/7)c
m = (3/7)c
7s = 5c
7s = 5(14/3)j
s = (10/3)j
Putting this all together:
m = (3/7)c
m = (3/7)(7s/5)
m = (3/5)s
m = (3/5)(10/3)j
m = 2j
So we have found that one marble is equal in weight to 2 jujubes. Finally, we can use the third equation to find how many jujubes are equal in weight to 1 marble:
3c = 14j
c = (14/3)j
m = (3/7)c
m = (3/7)(14/3)j
m = 2j
1 marble = 2 jujubes
1 jujube = 1/2 marble
1 marble = 2 jujubes = 2(84) = 168 jujubes
Therefore, one marble is equal in weight to 84 jujubes.

A $70,000 mortgage is $629. 81 per month. What was the percent and for how many years?
9%, 20 years
9%, 25 years
7%, 20 years
9%, 30 years
Answers
The closest answer is 9% interest rate and 25 years term of the loan.
Assuming the $70,000 mortgage is a fixed-rate mortgage, we can use the formula for the monthly payment of a mortgage to solve for the interest rate and the term of the loan.
The formula is:
M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1 ]
where:
M = monthly payment
P = principal (amount borrowed)
i = interest rate (per month)
n = number of months
Substituting the given values, we get:
$629.81 = $70,000 [ i(1 + i)^n ] / [ (1 + i)^n - 1 ]
Using a mortgage calculator or by trial and error, we can find that the closest answer is 9% interest rate and 25 years term of the loan.

The domain in a set of ordered pairs is always the y-coordinate.
True or False
Answers
Answer: False
Step-by-step explanation: It is false because the y-coordinate is the range.
Albert and Makayla are each renting a car for one day. Albert’s rental agreement states that the car costs $35 per day and $0. 15 per mile driven. Makayla’s agreement states that the car she is renting costs $45 per day and $0. 10 per mile driven. Write an equation to determine the number of miles, m, Albert and Makayla drive if they spend the same amount of money on their rentals
Answers
To determine the number of miles, m, Albert and Makayla drive if they spend the same amount of money on their rentals, we can write an equation using the given information:
Albert's cost = $35 per day + $0.15 per mile driven
Makayla's cost = $45 per day + $0.10 per mile driven
Since they spend the same amount of money, we can set the costs equal to each other:
35 + 0.15m = 45 + 0.10m
Now, we need to solve the equation form, the number of miles driven:
1. Subtract 0.10m from both sides:
35 + 0.05m = 45
2. Subtract 35 from both sides:
0.05m = 10
3. Divide both sides by 0.05:
m = 200
So, if Albert and Makayla spend the same amount of money on their rentals, they both drive 200 miles.
