Answer:

Step-by-step explanation:

Volume =  

  4 × π × r³ / 3    <----- This is our volume equation

= 4 × π × 1.9³ / 3    (Substituted the unknown r for the radius given, 1.9 cm)

= 4 × π × 6.859 / 3      (Cubed it, aka: Multiplied 1.9 by itself thrice, 1.9 × 1.9 × 1.9

= 4 × 21.548184011 / 3      (Multiplied 6.859 by pi "π")

= 86.1927360439 / 3         (Multiplied that by 4)

= 28.7309120146 cm³     (Divided it by 3, gave it a ³ dimension because it is 3D, volume.

≈

28.73cm³ or 28.7cm³ or 29cm³.   (rounded answers, hundreths, tenths and ones)

Based on the question, I assume you got a couple of options to choose from and have to pick the closest? Pick the answer closest to the answers given above.

Answer:

(x + (3+5i))^2 = x^2 + 6x + (10x+30)i - 16

Step-by-step explanation:

Complex numbers identity:

The complex numbers identity is:

i^2 = -1

Square of the sum:

(x + y)^2 = x^2 + 2xy + y^2

In this question:

(x + (3+5i))^2

x^2 + 2x(3+5i) + (3+5i)^2

x^2 + 6x + 10xi + 9 + 30i + 25i^2

x^2 + 6x + 9 + (10x+30)i - 25

x^2 + 6x + (10x+30)i - 16

So

(x + (3+5i))^2 = x^2 + 6x + (10x+30)i - 16

Graph the equation on the coordinate plane. y=x-3 Select two points on the line to graph the line.​
yawa3891 [41]

The slope of a line is used to determine its steepness of a line.

What is the standard form of an equation?

One way of expressing linear equations is in their standard form. There are several ways to express a linear equation, including the standard form, the slope-intercept form, and the point-slope form. The general form of a linear equation, commonly referred to as the standard form, is written as Y = MX + C; A linear equation or one-degree equation is one in which the maximum power of the variable is 1. For instance, the equation 4x + y = 6 is linear since the maximum power of both x and y is 1. The equation in its standard form is written as Ax + By = C, where A, B, and C are all integers and x and y are the variables.

The standard formula for finding the equation of a line is expressed as:

y = mx + b

m is the slope

b is the y-intercept

Given the equation:

y = x -3;

The slope of the graph will be 1 with no y-intercept.

The slope of a line is used to determine its steepness of a line.

So, substituting the value of x as 0;

So, The value of y will be -3;

That is: (x,y) = (0,-3);

Now, substituting x =1;

So, The value of y will be: -2;

That is: (x,y) = (1,-2);

Hence,

The slope of a line is used to determine its steepness of a line.
