Let A be the set of all integers which are 3 more than some perfect square. Here are some examples of such integers are: 4 = 1 +

3, 7 = 4 + 3, 3 = 0 + 3, 28 = 25 + 3, Write out the set A as succinctly as you can, using the set-builder notation.

Answer:

A = \{x|x\ E\ n^2 + 3, n \geq 0 \}

Step-by-step explanation:

Required

Represent set A using set-builder notation

First, we need to understand the general rule:

0^2 + 3 = 0 + 3 = 3

1^2 + 3 = 1 + 3 = 4

2^2 + 3 = 4 + 3 = 7

5^2 + 3= 25 + 3 = 28

In general, we can write it as:

n^2 + 3

Next, is to determine the values of n;

<em>Since </em>n^2<em> is a perfect square of </em>n<em>, then, the values of n is 0,1,2,3,.....</em>

Hence; Set A can be represented as: A = \{x|x\ E\ n^2 + 3, n \geq 0 \}

A point p in the first quadrant lies on the parabola y=x^2. Express the coordinates of p as a function of the angle of inclinati
max2010maxim [7]

Answer:

  • The coordinates of the point p are:       (x,xtan\alpha )

                   

           

Explanation:

1. Name the angle of inclination of the line joining p to the origin α.

2. Find the relation between the coordinates of the point (x,y)

When you draw a line from the origin to the parabola, the intersection point, p(x,y) will have coordinates (x,y).

As per the definition of the tangent trigonometric ratio you have:

  • tan\alpha =\frac{y}{x}

From which you can clear y:

  • y=xtan\alpha =>(x,y)=(x,xtan\alpha )

Which is the expression of the coordinates of p as a function of the angle of inclination of the line joining p to the origin.

I just need help understanding linear equations and linear graphs with the equation: y=1/3x+3 Please explain the process
ANTONII [103]
1/3x let’s us the slope of the line is going up one and over three between each point. The +3 lets us know that the line will be located three points above the origin aka the middle/0,0 of the graph. Continuing this pattern will give you a positive linear line. The equation doesn’t make it so the line curves
