1. When a function passes the horizontal line test, we can infer that its inverse is both known and exists.

You can use the vertical line test to determine whether an expression is actually a function; if it succeeds, it is. If the graph does, in fact, pass the vertical line test before passing the horizontal line test, it is a function. If it also passes the horizontal line test, it is a one-to-one function, which means there is a unique x-coordinate value for every unique y-coordinate value. Only one-to-one functions have an inverse expression that is also a function.

Graph:

A graph is a logical visual representation of any data in mathematics. The correlation between the variable values is depicted on the graph. A graph is used in graph theory to depict a group of items that are interconnected in some way. In essence, the vertices or nodes of the objects are mathematical notions, and the edges are representations of the connections between the nodes. In mathematics and statistics, many graph types are used to visually display data. The study of points and lines is the focus of the field of graph theory. It is a branch of mathematics with a focus on graph analysis. The mathematical truth is clearly illustrated in this artwork. Relationships are studied using the graph theory.

Answer:

Minimum Unit Cost = $14,362

Step-by-step explanation:

The standard form of a quadratic is given by:

ax^2 + bx + c

So for our function, we can say,

a = 0.6

b = -108

c = 19,222

We can find the vertex (x-coordinate where minimum value occurs) by the formula -b/2a

So,

-(-108)/2(0.6) = 108/1.2 = 90

Plugging this value into original function would give us the minimum (unit cost):

The vertices of the original triangle are:

(-3,-2) , (0,6) and (1,3)

Given,you rotate a triangle 270° counterclockwise about the origin.

Then you translate its image 2 units right and 1 unit down.

The vertices of the final image are (0, 2), (8,-1), and (5,-2).

we are asked to find  the vertices of the original triangle =?

Before translating the image of final image 2 units right and 1 unit down.

the vertices of the triangle is:

(0-2,2+1) → (-2,3)

(8-2,-1+1) → (6,0)

(5-2 , -2+1) → (3,-1)

{translate the final image 2 units left, 1 unit up again}

then before rotate 270° counterclockwise.

the vertices of the triangle is:

(-2,3) → (-3,-2)

(6,0) → (0,6)

(3,-1) → (1,3)

{rotate 270° clockwise again }

Hence the vertices of the original triangle is:

(-3,-2) (0,6) and (1,3)

Hence we get the required vertices of the triangle.

Answer:

Cost = $83.44

Step-by-step explanation:

The given equation is,

→ c(d) = 0.24d + 34

Now the required cost will be,

→ c(d) = 0.24d + 34

→ c(206) = 0.24(206) + 34

→ c(206) = 49.44 + 34

→ c(206) = $83.44

Hence, the cost is $83.44.

The number of green fish are in the aquarium is 6.

Given that,

The aquarium has 3 more yellow fish than green fish.

60 percent of the fish are yellow.

Let us assume the green fishes be x and the yellow fishes are y.

Total no of fished = x + y.

And, y = x + 3

Based on the above information, the calculation is as follows:

Now, put y = x + 3

So,  

60%(y+x)=y

[tex]\frac{60}{100}(x+3+x)=x+3[/tex]

60(2x+3)=100(x+3)

120x + 180 = 100x + 300

20x = 120

x = 6

Hence the number of green fishes are x=6

You can see in the following image. The triangles are the same, in other words congruent. How I figured it out was by making a random triangle (ABC) then finding the lengths and angles.  From there, I picked a random side (AB) and angles (A) and (B) after I transferred the information I had and put it into a new triangle. Using this formula to determine the third angle: 3rd angle (C = 45*) = 180* - angle A (45*) - angle B (90*). From there, I looked for where line (BC) and (CA) would connect.

Step-by-step explanation:

Valentina should use a gear on the back wheel that has larger diameter to be more efficient

The problem deals with circumference of the wheel.

Circumference is a function of diameter such that: A larger wheel will have a larger circumference and a smaller wheel will have a smaller circumference

The wheel is assumed to be a circle and equation of circumference of a circle is pi * diameter

Gear has the function of rotating the wheel when a gear makes a initiates one revolution of the wheel

say wheel x, diameter = 5 and wheel y, diameter = 10

distance covered by one revolution = circumference

circumference of x = pi * 5 = 5pi

circumference of y = pi * 10 = 10pi

comparing both shows that wheel y will cover double the distance of x hence more efficient.

In the velocity - time graph, the value of t is 180 seconds

Velocity-time graph is a plot between Velocity and Time. It shows the Motion of the object that moves in a Straight Line. Magnitude of Velocity at a given instant is equal to its Instantaneous Speed. It is drawn for 1-D motion only and can take both positive and negative values.

The formula of speed by using the distance and time represented as

speed = distance / time

In the velocity time graph, we have we walked back home at constant speed of 2m/s

This can be represented mathematically as

2 = 150 / t - 105

solve for t in the equation

150 = 2(t - 105)

150 = 2t - 210
