Answer:

-8/117

Step-by-step explanation:

[tex]\frac{-2}{9} /3\frac{1}{4} \\\\[/tex]

-first simplify 3 1/4

-simply multiply 4 by 3 and add 1. This is how you convert mixed fractions to whole fractions. Multipy denominator by whole number and add the numerator. The denominator stays the same so this will become

=13/4

- next because you're dividing two fractions, it is easier to take reciprocal of the denominator. You flip the fraction and change the sign. So instead of dividing by 13/4, you multiply by 4/13

- lets move the negative fraction (-2/9) to rigth hand side to make things easier to visualize. so our expressions right now will be:

=[tex]\frac{4}{13} *\frac{-2}{9}[/tex]

-now multiply like normal

= -8/117

The product of (-8) and a number at most 50 will be

50 * (-8) = -400

Mathematicians use multiplication to calculate the sum of two or more numbers. It is one of the fundamental operations in mathematics that we perform on a daily basis.

Multiplying in math is the same as adding equal groups. The number of items in the group grows as we multiply. Parts of a multiplication issue include the product, the two factors, and the product. The components in the multiplication problem 6 x 9 = 54 are the numbers 6 and 9, and the result is the number 54.

a mathematical operation that accepts two integers and outputs a result that is equal to the sum of a column that has one of the values repeated the same amount of times as the other number. Eight times three equals the total of eight times eight.

The value of t is 20 percent greater than the value of r

Here, the value of r is 4/5 times the value of t.

This means, the value of r would be,

r = (4/5)t

This means, the value of t is greater than the value of r by (t - r)

We find the value of (t - r)

t - r

= t -  (4/5)t

= t (1 - 4/5)

after simplifying this expression we get,

t - r = (1/5)t

This means, the value of t is greater than the value of r by (1/5)

Answer:

Step-by-step explanation:

a. The y coordinate of the center of the circle is -1.

b. The value of b in the equation is 44 units.

The solution has been obtained using circles.

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

Hence, the value of b is 44 units.

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.

The function f(x) is equal to x√x.

The value of a is 25/4.

What is a function?

A function in mathematics from a set X to a set Y assigns exactly one element of Y to each element of X. The sets X and Y are collectively referred to as the function's domain and codomain, respectively. Initially, functions represented the idealized relationship between two varying quantities.

Given integration is

[tex]5+\int_a^x\frac{f(t)}{t^2}dt =2\sqrt{x}[/tex]

Rewrite the equation

[tex]\int_a^x\frac{f(t)}{t^2}dt[/tex]= 2√x - 5

The differentiation of 2√x is f(t)/t² at t = x.

The differentiation of 2√x is 1/√x.

Therefore, 1/√x = f(x)/x²

x²/√x = f(x)

f(x) = x√x

Putting f(t) = t√t in the given equation:

[tex]5+\int_a^x\frac{t\sqrt{t} }{t^2}dt =2\sqrt{x}[/tex]

[tex]\int_a^x\frac{1 }{\sqrt{t}}dt =2\sqrt{x}-5[/tex]

[tex][2\sqrt{t}]_a^x[/tex] = 2√x - 5

2√x - 2√a = 2√x - 5

2√a = 5

Answer:

The equation y = -2x + 1 describes a line on a coordinate plane. To find two ordered pairs that work, you can pick any two x-values and plug them into the equation to get the corresponding y-values. For example, if you choose x = -1 and x = 4, then the corresponding y-values are y = -2(-1) + 1 = 1 and y = -2(4) + 1 = -7. This means that the two ordered pairs that work are (-1, 1) and (4, -7).

The expression 450 – 3x can be used to represent the amount of tea leaves remaining after x days.

Each day, Leon uses 3 grams of tea leaves to make a cup of tea. Therefore, the amount of tea leaves remaining can be calculated by subtracting the amount used each day from the initial amount of tea leaves.

450 (initial amount of tea leaves) - 3x (amount used each day) = remaining amount of tea leaves after x days.

Therefore, the expression 450 – 3x can be used to represent the amount of tea leaves remaining after x days.

Answer:

This equation is a difference of squares factorization. It states that the difference between the square of x and 7x plus some constant c is equal to the square of (x+a). To solve for a and c, we can expand both sides of the equation:

X^(2) - 7x + c = x^(2) + 2ax + a^(2)

And we can set them equal to each other and solve for a and c:

x^(2) - 7x + c = x^(2) + 2ax + a^(2)

-2ax - a^(2) = -7x + c

a = (7x - c) / 2x

c = x^(2) - 7x + a^(2)

Note that this is valid as long as x is not equal to 0.

Approximately 33,510.7 cubic millimeters.

Step-by-step explanation:

The volume of a sphere can be calculated using the formula: V = 4/3 * π * r^3, where r is the radius of the sphere.

The diameter of the table tennis ball is 40 mm, so the radius is r = 40/2 = 20 mm.

To convert millimeters to cubic millimeters we have to cube the value of radius, so in this case, 20mm20mm20mm.

So, the volume of the table tennis ball in cubic millimeters is:

V = 4/3 * π * 20^3 = 4/3 * π * 8000 = approximately 33,510.7 cubic millimeters.

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.
