Jamal will have 63 vacation days after working at his new job for 2 years.

To calculate the number of vacation days Jamal will have after 2 years,

We need to determine the number of months he worked

(2 years = 2 * 12 = 24 months)

And then use that in the expression for his vacation days: 51 + 0.5m.

So, for 24 months, we have:

Vacation days = 51 + 0.5 * 24

Vacation days = 51 + 12

Vacation days = 63

The total distance covered by the circle is  15.14 inches.

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

Given, A circle with a radius of 1 inch rolls without slipping along the sides of a right triangle.

We know the distance around the triangle is the perimeter of the triangle.

The perimeter of the triangle is the sum of the lengths of all the sides.

Here, 'M' is the perimeter and 'N' is the number of complete rotations.

Therefore,

M + Nπ.

= (3 + 4 + 5) + 1(3.14).

= 12 + 3.14.

The equation of the tangent line of f(x)=(x-5)/(x+1) at x=6 in the form of y = mx + b is y = (6/49)x - 29/49 .

The function whose tangent line is to be found out is f(x)=(x-5)/(x+1) ;

to find the tangent equation , we differentiate the function ;

the function f(x) is of the form g(x)/h(x) ;

On differentiating g(x) and h(x) , we get that g'(x) = h'(x) = 1 ;

We get ; f'(x) = [1(x+1))-(1(x-5)]/(x+1)² ;

⇒ f'(x) = [x+1-x+5]/(x+1)² ;

⇒ f'(x) = 6/(x+1)² ;

Now, we x = 6 in the derivative to find slope of tangent at that point.

So , ⇒ f'(6) = 6/(6+1)²

⇒ f'(6) = 6/49

Now the slope is =  6/49 ,  the value of y in (6,y) by putting in x = 6 into the original function:

⇒ f(6) = (6 - 5)/(6 + 1)

⇒ f(6) = 1/7

We currently know a point (6,1/7) = (x₁,y₁) and slope of tangent, which is 6/49.

now using  point slope form to find equation of tangent.

⇒ y-y₁ = m(x-x₁)

⇒ y - 1/7 = (6/49)(x-6)

⇒ y = (6/49)x - 29/49

Therefore , The equation of the tangent is y = (6/49)x - 29/49 .

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.

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

We write proportions to construct equivalent ratios and to resolve unclear values. a comparison of two integers and their proportions. According to the law of proportion, two sets of given numbers are said to be directly proportional to one another if they grow or shrink in the same ratio.

Here the given is V∝[tex]r^3[/tex] .

To remove proportion we need to include constant then,

=> V = k[tex]r^3[/tex]

Now put r=1 and V= 4 then

=> 4= k*1

=> k=4

Then the equation is V=4[tex]r^3[/tex].

Now put r=2 then

=> V= 4[tex]\times 2^3[/tex]

=> V= 4× 8 = 32

Now put V=256 then

=> 256 = 4[tex]r^3[/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:

cos^2(60)= (1/2)^2       --------2

From equation 1 &2

1/2 + 1/4 + cos^2(y) =1

cos^2(y) = 1- (1/2 + 1/4)

cos^2(y) = 4-2-1/4

There are six functions of an angle commonly used in trigonometry. Their names and abbreviations are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).

Given that, Cos^2(45) + cos ^2(60) + cos^2(y) = 1

We Know that ,

cos(45) = 1/[tex]\sqrt{2}[/tex]  and cos(60) = 1/2

hence, Cos^2(45) = (1/[tex]\sqrt{2}[/tex])^2          (1)

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.

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.

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.

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.
