What is f 0 in a function?
The expression f (0) in a function is used to represents the y-intercept on the graph of the function f (x).
The point where the graph cuts the y - axis is known as the y - intercept whereas the point where it cuts the x - axis is known as x - axis. The graph cuts y- axis when the value of x coordinate is 0.
The values which satisfies the equation is known as the zeros of the function. The graph of a function is the set of all points in the plane of the form (x f(x)).
The graph of f could similarly be defined as the graph of the equation y = f(x). As a result, the graph of a function is a subset of the graph of an equation.

Prove that the angle between any two diagonals of a cube is given by cos=1/3
Consider a cube of side a units, with sides along x, y and z axis and one vertex at origin, as in the figure.
Here AB and CD are two diagonals of the cube, because A and B are diagonally opposite corners, also C and D.
In the figure, coordinates of A is (0, 0, 0) and that of B is (a, a, a). Then vector AB is given by,
[tex]\vec{\rm{AB}}=\rm{\left < a,\ a,\ a\right > }[/tex]
Coordinates of C is (a, 0, 0) and that of D is (0, a, a). Then vector CD is given by,
[tex]\vec{\rm{CD}}=\rm{\left < -a,\ a,\ a\right > }[/tex]
The diagonals each have a magnitude of a√3.
[tex]|\vec{\rm{AB}}|=|\vec{\rm{CD}}|=\rm{a\sqrt3}[/tex]
In the figure θ is the angle between the diagonals.
We take the dot product of the vectors AB and CD to get angle between them.

a the unit vector in the same direction of a
b the angle that a makes with the positive x-axis.
The unit vector in the same direction will be equal to (6 i/5.1 - 3 j/5.1).
What is a Vector?A vector is a quantity with both magnitude and direction in physics. It is often depicted by an arrow with the same direction as the amount and a length proportionate to the size of the quantity.
A vector lacks position, but has magnitude and direction. A vector is therefore unaffected by displacement parallel to itself as far as its length is unaltered.
As per the given data in the question,
The unit vector is calculated as:

The y-intercept is the point on the graph where it crosses the y-axis, and has coordinates of (0, b). The y-coordinate is the value of b in the slope-intercept form. The Slope is - ⅖.
What is the Slope and Y-intercept of a Line?Y-intercept = (0, 4), where b = 4
Given the linear equation in standard form, 2x + 5y = 20, where A = 2, B = 5, and C = 20:
Start by transforming the standard equation into its slope-intercept form, y = mx + b, where m = slope, and b = y-intercept.
Subtract 2x from both sides:
2x -2x + 5y = - 2x + 20
5y = -2x + 20
Divide both sides by 5 to isolate y:
y = - ⅖x + 4 ⇒ This is the slope-intercept form where the slope, m = -⅖, and the y-intercept, b = 4. The y-intercept is the point on the graph where it crosses the y-axis, and has coordinates of (0, b). The y-coordinate is the value of b in the slope-intercept form.

How do you know which graph is greater?
To determine which graph is greater, you need to compare the y-values of the two graphs at the same x-values or look at the overall shape of the graphs.
You can compare the y-values of the two graphs at the same x-values to determine which graph is greater if one graph has a higher y-value than the other graph at a particular x-value, then the first graph is greater at that x-value.
For example, suppose you have two graphs: one is a straight line with a slope of 2 and the other is a straight line with a slope of -3. If you compare the two graphs at the same x-values, you will see that the graph with the slope of 2 has a higher y-value than the graph with the slope of -3 for all x-values. This means that the graph with the slope of 2 is always greater than the graph with the slope of -3.
You can also compare the graphs by looking at the overall shape of the graphs. For example, if one graph is always above the other graph, then it is clear that the first graph is greater. On the other hand, if one graph crosses over the other graph, then there may be some x-values for which one graph is greater and some x-values for which the other graph is greater.

y = 0.4 when x = -1
Answer:
k = - 0.4 , y = - 0.4x
Step-by-step explanation:
given y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
to find k use the condition y = 0.4 when x = - 1 , then
0.4 = - k ( multiply both sides by - 1 )
- 0.4 = k
then constant of variation is k = - 0.4

As per the details given in the question,
Rate, r = 5.3%
Time, t = 5 years
Amount = $1030
As per the formula of compound interest:
x × (1 + 5.3%/4)⁽⁵⁾⁽⁴⁾ = 1030
x × (1 + 53/4000)⁽⁵⁾⁽⁴⁾ = 1030
Now, calculate the product,
x × (1 + 53/4000)²⁰ = 1030
x × [(4000 + 53)/400]²⁰ = 1030
x = 1030/(4053/4000)²⁰
x = (1030 × 4000²⁰)/4053²⁰
x = 792.
