Answer:
75
Step-by-step explanation:
let the number of texts equal T
total amount charged by talk company - 15 + 0.1T
total amount charged by mobile service = 0.3T
we are to find the number of texts that would make the charges equal
15 + 0.1T = 0.3T
Collect like terms
15 = 0.3T - 0.1T
15 = 0.2T
T = 15/0.2 = 75
The answer to this question is that the period is 6*pi/5. The period of y = sin(bx) is given by
period = 2pi/b
so with b = 3/5, that is the result.
The coordinate pair (-4,5) could be the fourth vertex of the square.
<h3>Quadrilaterals</h3>
There are different types of quadrilaterals, for example: square, rectangle, rhombus and trapezoid. Each type is defined accordingly to its length of sides and angles. For example, the square has all side equals and angles equal to 90°.
For solving this question, you should plot the given points as shown in attached image. Note that you have only two sides of a square, and you need a point (W) for completing the square.
As you have a square, all sides should have the same dimensions and all angles should equal to 90°. Therefore, the coordinates for the point W should result in equal and parallel sides XY and XZ. For this, from the attached image, you can see that the x-coordinate for the point W should be equal to the x-coordinate for the point Z. And, the y-coordinate for the point W should be equal to the y-coordinate for the point Y.
Thus, coordinate pair (-4,5) would be the fourth vertex of the square.

Let x be the whole number. x^2 is the square of the number. x-1 is the preceding number. And x+1 is the following number.
(x+1)(x-1)=
x^2 + x - x - 1
x^2 -1
Your answer is x^2-1 which is one less that x^2. This also means that the square of any whole number (x^2) is one greater than the product of the preceding (x-1) and the following (x+1).
