Consider the expression below. 1.3 + 1.25
Sarah thinks that this sum will be an irrational number. Is Sarah's classification correct? Why or why not?
A Sarah is not correct, because 1.3 + 1.25 can be rewritten as + which results in the rational sum of 2
B. Sarah is not correct, because 1.3 + 1.25 results in a decimal number and all decimals are rational.
C. Sarah is correct, because 1.25 cannot be rewritten as a fraction which means the sum is irrational.
D.
Sarah is correct, because 1.3 cannot be rewritten as a fraction or terminating decimal which means the sum is
irrational

From the given graph, the rise, run and slope of this graph are 1, 5, and 1/5 respectively.

This is the ratio between the rise and run i.e y-axis and x-axis.

The rise any graph is the change in the y-axis.

[tex]\delta y = y_2 - y_1[/tex]

The rise in this graph will be

[tex]\delta y = 1 - 0 = 1[/tex]

The run on any graph is the change in the x-axis.

[tex]\delta x = x_2 - x_1[/tex]

The run on this graph is

[tex]\delta x = 5 - 0 = 5[/tex]

Having the values of rise and run, we can find the slope of this graph

[tex]m = \frac{\delta y}{\delta x} = \frac{1}{5}[/tex]

The rise, run and slope of this graph are 1, 5, and 1/5 respectively.

Given parameters:

 x = 4

   Function;

           F(x) = x³ + 2x² + 1

Solution:

This is a  function related problem.

A function shows the relationship between two sets usually a domain and its range.

   For the given function;

                F(x) = x³ + 2x² + 1

                F(4)  = 4³ + 2(4)² + 1

                F(4) = 64 + 32 + 1  = 97

The value of the function is 97.

The system of equations for the ages of Wendi and Zaviel can be obtained as  x = y + 6 and x + y = 30 respectively.

A system of linear equations is a group of  equations having same number of variables and degree.

For the n number of variables n number of equations are required.

On the basis of number of solutions a system of equations can be classified as consistent and inconsistent.

Suppose the age of Wendi and Zaviel be x and y respectively.

Then, the equation for their age can be written as,

x = y + 6

And, the equation for the sum of ages is given as,

x + y = 30

Hence, the equations that represent the given case are x = y + 6 and x + y = 30 respectively.

The second number in the ordered pair is the y coordinate.

The second value of an ordered pair is the y-value.

It signifies how far above (or below) the x axis o (horizontal axis) that a point is. If the y value is positive, then the point is above the x-axis, but if it is negative it is below the x axis (when it's 0, the point is on the x-axis)

**NOTE** the x and y axes are on the Cartesian plane

Answer:

tan(x) = 1

sec(x) = sqrt(2)

Step-by-step explanation:

(Reminder: sin is the height of the triangle of the unit circle and cos is the length)

The only values where a right triangle with a hypotenuse of 1 has equal lengths of legs are 45-45-90 triangles. The sin and cosine of those triangles are both 1/sqrt(2).

Since tan(x) = sin(x)/cos(x), and sin(x) = cos(x), tan(x) is just going to be 1.

sec(x) is defined as 1/cos(x). since cos(x) is 1/sqrt(2), sec(x) is just sqrt(2).

Answer:

-48j²-28j+10

Step-by-step explanation:

Multiple each term in the first parentheses by each term in the second parentheses (FOIL)

2×5 + 2×6j - 8j×5 - 8j×6j

Multiple the numbers

=10 + 2 × 6j - 8j × 5 - 8j × 6j

=10 + 12j - 8j × 5 - 8j × 6j

=10 + 12j - 40j - 8j × 6j

= 10 + 12j - 40j - 48j²

Collect like terms

10 - 28j - 48j²

Reorder the terms using the commutative property

-48j² - 28j + 10
