f(x) = x² + 1, x > 0
y = x² + 1
x = y² + 1
x - 1 = y²
√x - 1 = y
√x - 1 = f(x), x > 1

Uses of the following button in a keyboard: Prt SC, Home, Shift, Tab, Pg Up.

creativ13 [48]

Answer:

This Print Screen key is used to take the screenshots of all that is appearing on the screen, and this can then be pasted in paint and saved in some location of the computer.

The Home key takes the cursor from the current position to the top left, or the start of the file.

Shift: There are two shift keys. And they are used to print the character in the capital. And when the caps lock is busy it can be used to print in lower case. It is also used together with arrow keys to select a part of the text.

Tab: This key moves the cursor from the current location to the location which we know as tab stops ( and the very next one).

Pg Up: The page up is being used for scrolling up, and the distance to which limit the scrolling will take place depends upon the application you are working on.

Answer:

D. System Analysis

Explanation:

System analysis can be defined as the process of analysing a problem in order to the know the cause thereby finding a way to resolve it or finding a solution to it.

System analysis enables us to easily study procedure or process thereby identifying what the objective of the procedures is which will in turn help to achieve what we needed to achieve.

System analysis is important because it enables easier identification of a problem which make us to find the best way to solve the problem since it is a problem solving technique which ensures that all problem are been resolved accurately and efficiently

Does a triangle with sides of lengths 1.5 ft, 2.5 ft, and 2 ft form a right triangle? How do you know?

timama [110]

Answer:

Yes, the side lengths of 1.5, 2.5, and 2 ft form a right triangle.

Explanation:

Before we solve this problem, we need to know a couple of things.

In a right triangle, you have two legs and a diagonal line that goes from one leg to the other or from one side to the other. This line is called the hypotenuse. It is the longest side of a right triangle. This length can be calculated by using a special formula that is over a thousand years old.

The formula is called the Pythagorean Theorem.

The formula states that if you square one leg and the other leg and add it up. You get the side of hypotenuse which is squared as well.

Here it is in simple terms: $a^{2} +b^{2} =c^{2}$ .

a and b are your two legs.

C is your hypotenuse.

In this case 1.5 and 2 are your legs and 2.5 is your hypotenuse since it is the longest side.

Before we calculate, there is a converse to the Pythagorean Theorem.

If $a^{2} +b^{2} \neq c^{2}$ , then it is not a right triangle.

Lets make 1.5 for a

and 2 for b.

We know 2.5 is for c.

Here it is.

$1.5^{2} +2^{2} =2.5^{2}$ . The / means it is a fraction.

1.5 squared is 9/4 and 2 squared is 4. Add 4 and 9/4 and you get 25/4 squared. Take the square root of 25/4 and you get 5/2.

5/2 is equal to 2.5, so the Pythagorean Theorem applies to this triangle. Therefore, these side lengths do form a right triangle.

Hope this helps!
