According to the information and the graph, the best place for Lois Lane to stand to receive the keys from Superman is in the middle of the Krytonite cage because it is the closest place to the point where superman is standing.
At what point should Lois Lane be located?
The point where Lois Lane should stand is in the middle of the cage because there he will have a better chance of receiving the Kronite keys that he has. Additionally, this point is the closest to the point where Superman is standing so he wouldn't have to go near the krionite and could throw the keys from there.

chandler is building a wooden birdhouse for his mom. he finds a plank in the garage to use for the base. when he realizes it's too long, chandler cuts 3 inches off the plank. now it's the correct length of 8.25 inches.which equation can you use to find the length p of the plank before chandler cuts it?
Answers
The equation p = 8.25 + 3 inches can be used for finding the length p of the plank before chandler cuts it.
Addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.
In mathematics, addition is the process of joining two or more integers. The numbers being added are known as addends, and the result or final response obtained after the procedure is known as the total.
From the given data,
The length of the plank cut by the chandler =3 inches
The correct length = 8.25 inches.
So, for finding the value of the length p of the plank before the chandler cuts, we will add the value of the correct length and the length of the plank cut by the chandler.
So, the value of p will be: 8.25+3 = 11.25 inches.

.the function f(x)=x-5 represents the cost of the jeans if you use the coupon
.the function g(x)=0.25x represents the cost of the jeans if you apply the store discount of 25% first
You find a pair of jeans for $36. How much would you pay for it using h(x)? How much would you pay using j(x)? Explain which function composition will give you the better discount?
Answers
Answer:
The function h(x) represents the cost of the jeans if you first use the coupon and then apply the store discount. The function h(x) can be computed using the composition of functions f(x) and g(x). The function j(x) represents the cost of the jeans if you first apply the store discount and then use the coupon. The function j(x) can be computed using the composition of functions g(x) and f(x).
If you use the composition h(x), you will pay $27 for the jeans. If you use the composition j(x), you will pay $30 for the jeans. Therefore, the composition h(x) will give you a better discount since it is cheaper.

Give an exact condition for when a rational number p, q E Z,q 0 has a a terminating base 60 representation. Prove your assertions. (b) What about base n?
Answers
A rational number p/q has a terminating base 60 representation if q is a factor of 60. This can be proven by noting that q is a factor of p if and only if the remainder of p divided by q is 0. For any base n, q must be a factor of n in order for p/q to have a terminating base n representation.
A rational number p/q has a terminating base 60 representation if q is a factor of 60. This can be proven by noting that q is a factor of p if and only if the remainder of p divided by q is 0. This can be seen by noting that if q is a factor of p, then p can be written as a multiple of q, or p = kq, where k is an integer. Thus, p/q = k, and the remainder of p divided by q must be 0. If q is not a factor of p, then the remainder of p divided by q will not be 0. Thus, for a rational number p/q to have a terminating base 60 representation, q must be a factor of 60. To determine if q is a factor of n for any base n, we must again consider the remainder of p divided by q. If the remainder of p divided by q is 0, then q is a factor of n, and the rational number p/q will have a terminating base n representation. If, however, the remainder of p divided by q is not 0, then q is not a factor of n and the rational number p/q will not have a terminating base n representation.

Answers
If the arr = {2, 6, 10, 99, 898) and key = 898 , then the depth of recursion in the binary search is (c) 2 .
The Depth of Recursion in Binary Search refers to the number of recursive calls required to find the target element in the array.
In the Binary Search, the array is repeatedly divided in half until , we find the target element or conclude that it is not present in the array.
The target element (Key) is = 898 and the array is {2, 6, 10, 99, 898} .
The initial array is divided into two parts: {2, 6, 10, 99} and {898} ;
Since 898 is larger than 99, we only need to consider the right half of the array: that is {898}.
The next step is to compare the target element (Key) = (898) with the middle element which is {898} .
and Since they both are equal, we have found the target element.
Therefore , the depth of recursion in this binary search is (c) 2.

Answers
Therefore, the following claims are justified:
e. A political reporter claims that at least 45% of registered voters favor this candidate. (This claim is supported by the lower bound of the confidence interval.)
The following claims are not justified:
a. A political reporter claims that 90% of registered voters favor this candidate. (This is not a correct interpretation of the confidence interval, which only provides a range of likely values for the true proportion of voters who support the candidate, not the exact value.)
c. A political reporter claims that at least 53% of registered voters favor this candidate. (This claim goes beyond the information provided by the upper bound of the confidence interval, which only indicates that there is a 90% probability that the true proportion of voters who support the candidate is less than or equal to 0.53.)
d. A political reporter claims that the majority of registered voters favor this candidate. (This claim goes beyond the information provided by the confidence interval, which does not indicate whether the majority of voters support the candidate or not. A majority is defined as more than 50%, so further analysis would be required to determine whether the majority of registered voters support the candidate or not.)

Irreflexive closure is the creation of a new binary relation by adding irreflexivity property, meaning no element is related to itself.
What is binary ?
A binary number is a number expressed in the base-2 numeral system or binary numeral system, a method of mathematical expression which uses only two symbols: typically "0" and "1".
An irreflexive closure is a mathematical concept that refers to the creation of a new binary relation from a given binary relation by adding the property of irreflexivity. A binary relation is irreflexive if it does not relate any element to itself. The irreflexive closure of a binary relation is the smallest irreflexive relation that contains it.
In other words, the irreflexive closure of a binary relation is a modified version of the original relation where no element is related to itself. The process of finding the irreflexive closure involves removing all self-referential relationships and adding new relationships to preserve the original relationships between elements.

What is a circle?
A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point.
a. We are given the equation as
x² + y² - 4 x + 2 y = b
On solving the equation, we get
x² - 4 x + 4 + y² + 2 y + 1 = b + 4 + 1
This can be written as
( x - 2 )² + ( y + 1 )² = b + 5 ...(1)
So, the y - coordinate of the center of the circle is - 1.
b. We know that equation of circle is
( x - a )² + ( y - c)² = r²
On comparing this with (1), we get
b + 5 = r²
b + 5 = 7²
b + 5 = 49
b = 49 - 5
b = 44

triangle area =1/2*6* height
height² =6²-3² =36-9 = 27
so height = 5.2
triangle area =1/2*6* 5.2 =15.6
so the sliver = 49π/6 -15.6 =10
