Vertical Line is a line that runs perpendicular to the Y-axis. It runs in a straight line from top to bottom and vice versa. Any point along this line will have the same x-coordinate value.
No slope exists along the vertical lines. Since it follows the y-axis parallel, the slope cannot be determined. As a result, x = an is the equation for the vertical line that, at any point, say "a," crosses the x-axis.
Since a vertical line has no y-intercept and 0 for the slope denominator, its slope is infinity or undefined.
In mathematics, we use a vertical line to determine whether the relationship is a function. If all vertical lines crossed it no less than once, it would be a function. Another name for this is the vertical line test. If a graph only has one output (y) for each input (x), it will be regarded as a function. A vertical line is therefore not a function.

How do you graph vertical and horizontal shifts?
To graph a vertical shift, take the original graph and move it up or down on the y-axis. To graph a horizontal shift, take the original graph and move it left or right on the x-axis.
Vertical shifts can be graphically represented by taking the original graph and moving it up or down on the y-axis. This is accomplished by adding a constant value to every y-value in the equation. For example, if the equation is y = x + 2, shifting the graph up two units on the y-axis would change the equation to y = x + 4. Horizontal shifts can be graphically represented by taking the original graph and moving it left or right on the x-axis. This is accomplished by adding a constant value to every x-value in the equation. For example, if the equation is y = x + 2, shifting the graph two units to the right on the x-axis would change the equation to y = x - 2. When graphing vertical or horizontal shifts, it is important to remember that the overall shape of the graph remains the same, only the position of the graph changes.

If tangent of x degrees equals four-thirds, what is the value of b? triangle lmn in which angle m measures 90 degrees, angle l measures x degrees, lm measures 10.5 units, and nm measures 2b units b = 4 b = 5 b = 6 b = 7
The value of b is equal to seven
if the tangent of x degrees is equal to four-thirds, the triangle's area is 10.5 units, and the length of the NM is 2b units. In this case, b = 7, hence the last choice is right.
Triangles are described as having right angles.Has three sides in the normal sense, where the total of any two sides is always greater than the third side. One kind of triangle is the right angled triangle.
A right angle triangle is one that has angle
between its two sides .
We also have a number of sides.
NM = 2b, LM = 10.5 length of side
x's tangent, tan x = 4/3
We must figure out what b is worth.
triangular base = LM = 10.5
As is common knowledge, the tangent of any angle equals the perpendicular to base ratio.
=>4/3 = 2b / 10.5
Tan x = 4/3 = LM/NM, thus.
=>4x 10.5 = 2b x 3

Nancy purchased some bed
sheets that cost $36. They were
on sale 25% off. What is the
new price of the bed sheets?
Answer:
To find the new price of the bed sheets, we can calculate the amount of discount first and then subtract it from the original price.
The bed sheets were on sale 25% off, so the amount of discount is:
$36 x 25/100 = $9
To find the new price of the bed sheets, we can now subtract the discount from the original price:
$36 - $9 = $27
So the new price of the bed sheets is $27.
Answer:
$36 * 0.75 = $27. That is the answer.
If 1.00 is 100 percent, subtract 0.25 or 25 percent from that to get 0.75 or 75 percent as the value which is left then multiply the original price, $36 to get the equation and answer above.
When a quadratic function is in factored form what information about the graph can be easily determined?
Equations may be solved and x-intercepts can be found very quickly when a quadratic expression is in factored form and equal to 0. Vertices, as well as the expression's maximum and minimum values, can also be identified.
A polynomial equation of degree 2 is a quadratic equation. A quadratic equation has the conventional form a[tex]x^2[/tex] + bx + c=0, where a, b, and c are all real values and a[tex]\neq[/tex]0.
The quadratic function y=a[tex]x^2[/tex] + bx + c, whose graph will be a parabola, is obtained if we substitute 0 with y.
The solutions to the equation a[tex]x^2[/tex]+bx+c=0 will be at the spots where the graph intersects the x-axis. In other words, if the polynomial a[tex]x^2[/tex]+bx+c can be factored to (x-p)(x-q), then (x-p)(x-q)=0 or (x-p)(x-q)=0 according to the zero product property. As a result, p and q are the x-intercepts of the quadratic equation and the solutions to the equation a[tex]x^2[/tex] + bx + c=0.

The product of two consecutive natural numbers is 1. 5 times the square of the lesser number.
The two consecutive natural numbers are 2 and 3.
Let x be the smaller number. Hence, the larger number will be x + 1.
The product of these two consecutive natural numbers is x(x + 1). It is stated in the problem that this product is 1.5 times as big as the square of the smaller number, x². So we can set up the equation:
x(x + 1) = 1.5x²
Expanding and simplifying the equation:
x² + x = 1.5x²
0.5x² - x = 0
x(0.5x - 1) = 0
x = 0 or 0.5x - 1 = 0
x = 0 or 0.5x = 1
x = 0 or x = 2
The smaller number cannot be 0, so the solution for the smaller number is x = 2 and the larger number is x + 1 = 2 + 1 = 3.

Total cost in single service crew is greater than double service crew. So, double service crew is cheaper.
We have, a crew of mechanics at the highway department garage repair vehicles. In case of poisson distribution,
λ = 3 vehicles every 12 minutes
= 3×60/12 = 3× 5
λ = 15 vehicles per hour
When time distribution is approximates an exponential distribution,
The mechanic crew can service an average, μ = 3 vehicles every 10 minutes
μ = 3×60/10 = 18 vehicles per hour
Cost for one service crew =$150 per hour
Cost associated with lost productivity from the breakdown or wait cost
=$50 per hour
For single crew, number of vehicles out of cost, Lₛ = 15/(18 - 15) = 15/3 = 5
Single service crew cost = $150 per hour
wait cost = $5×50 = $250 per hour
Total cost = $400 per hour
For double service crew, Number of vehicles out of service cost = 15/(36 - 15)
= 15/21 = 0.7143
Double service crew cost = 2× $150
= $300
Wait cost = $0.7143×50 = $35.715
