The graph that is decreasing when x > 3 is Graph y .

With graph W, when x > 3, the graph is still increasing as shown by the arrow going up . With graph x , when the graph gets to the point where x > 3, it will keep increasing as well .

For graph Y, the graph rises all the way up to x = 3 and then from there, begins to decrease. This means that for all points where x > 3, the graph would be decreasing.

The time complexity of uttkonen’s algorithm is option(a) that is

O (n log n)

The time complexity is the number of operations an algorithm performs to complete its task (considering that each operation takes the same amount of time). The algorithm that performs the task in the smallest number of operations is considered the most efficient one in terms of the time complexity.

O(log N) is a common runtime complexity. Examples include binary searches, finding the smallest or largest value in a binary search tree, and certain divide and conquer algorithms. If an algorithm is dividing the elements being considered by 2 each iteration, then it likely has a runtime complexity of O(log N)

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 range is 4.5, and it means that the data varies by a value of 4.5.

What is the data set?

A data set is an ordered collection of data. As we know, a collection of information obtained through observations, measurements, study, or analysis is referred to as data. It could include information such as facts, numbers, figures, names, or even basic descriptions of objects.

The range is the difference between the largest and smallest values in a data set.

In this case, the largest value is 8 and the smallest value is 3.5, so the range is 8 - 3.5 = 4.5.

This means that the ballet shoe sizes in this class vary by 4.5, with the largest size being 8 and the smallest size being 3.5.

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.

Distance = ✓2

Midpoint = (-4, 10)

Step-by-step explanation:

a.) (-3,8) and (-5,12)

These coordinates are (x,y)

Let's subtract the X's

-5-(-3) = -2

And for the Y's

12-8 = 4

Next, you would add these together

-2+4 = 2

Last step is squaring rooting this number

✓2, you can either find the actual square root by calculator or leave it as ✓2. This would be your distance.

Finding the midpoint is like the average. Right in the middle. So you would do the same with these.

To find X you'll add them then divide by 2 since there are 2 x coordinates

-3+-5 = -8

Divided by 2 = -4

Same with Y

8+12 = 20

Divided by 2 = 10

Now we can say the midpoint is (-4, 10)

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.

Answer:

Step-by-step explanation:

whole circle area = π r² = π*7² =49π

60 = 1/6 of the circle

so 49π/6 is the slice area

then minus the triangle area

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

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

x² - 4 x + 4 + y² + 2 y + 1 = b + 4 + 1

( 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
