Using square process method, we can get the values of x to be 12 and 6.
Define square process?The formula a (x + m)2 + n = a (x + m)2 + n is the simplest to remember while learning how to complete the square technique.
The following formulas can be used to compute m and n in this situation: m = b/2a and n = c - (b2/4a).
From the question,
x² - 18x + 72= 0
⇒ x² - 18x = -72
Complete the square by adding the half of the square of the coefficient of x to both sides of the expression as shown:
⇒ x² - 18x + (18/2) ² = -72 + (18/2) ²
⇒ x² - 18x + 9² = -72 + 81
⇒ (x-9) ² = 9
⇒ x-9 = ± 3
So, values of x are:
x = 3 + 9
= 12
x = -3 + 9
= 6
Therefore, the values of x are 12 and 6.

Please help me with this Special Right Triangle: 45-45-90
Answer:
x = 13.44 (2 d.p.)
y = 13.44 (2 d.p.)
Step-by-step explanation:
The interior angles of a triangle sum to 180°. Therefore, the missing angle of the given triangle is 45°. This means the triangle is a 45-45-90 triangle.
What is a 45-45-90 triangle?A 45-45-90 triangle is a special right triangle in that the measures of its sides are in the proportion x : x : x√2 where:
x are the sides opposite the 45 degree angles (legs).x√2 is the side opposite the right angle (hypotenuse).As the given triangle is a 45-45-90 triangle, sides x and y are the same length.
As the hypotenuse (side opposite the right angle) is 19 units in length, then x√2 = 19. To find the length of x (and y), solve for x:
[tex]\implies x\sqrt{2} = 19[/tex]
[tex]\implies \dfrac{x\sqrt{2}}{\sqrt{2}} = \dfrac{19}{\sqrt{2}}[/tex]
[tex]\implies x= \dfrac{19\sqrt{2}}{2}[/tex]

Hence, in answering the stated question, we may say that As a result, the function mass of the 30 cm long PVC pipe is roughly 733.48 grammes, rounded to the nearest tenth.
what is function?Mathematicians investigate numbers and their variants, equations and associated structures, forms and their locations, and prospective locations for these things. The term "function" refers to the relationship between a group of inputs, each with its own output. A function is a connection of inputs and outputs in which each input results in a single, distinct outcome. Each function has its own domain, codomain, or scope. The letter f is commonly used to denote functions (x). An x represents entry. On functions, one-to-one capabilities, so multiple capabilities, in capabilities, and on functions are the four basic types of accessible functions.
The volume of the PVC pipe can be estimated by subtracting the volumes of the outer and inner cylinders:
V = π/4 × (D² - d²) × L
where V denotes volume, is the mathematical constant pi (roughly equivalent to 3.14159), D denotes outer diameter, d denotes inner diameter, and L denotes pipe length.
V = π/4 × (6.5² - 5²) × 30\sV = 531.13 cm³
PVC pipe mass can be estimated by multiplying its volume by its density:
m = V × ρ

Step-by-step explanation:
A car travels at a constant speed of 60 miles per hour. The distance the car travels in miles is a function of time t , in hours, given by d ( t ) = 60 t . Find the inverse function by expressing the time of travel in terms of the distance traveled. Call this function t ( d ) . t ( d ) = Find t ( 160 ) . Round to 1 decimal place. t ( 160 ) =
If the car travels 160 miles, it will take approximately 2.7 hours to cover that distance.
An inverse function is a function that "undoes" the effect of another function. More specifically, if we have a function f(x), its inverse function g(x) will undo the effect of f(x), such that if we apply f(x) and then g(x) to an input x, we get back the original input.
To find the inverse function of d(t) = 60t, we need to solve for t in terms of d. We start by setting d equal to the original function and solving for t:
d = 60t
Dividing both sides by 60, we get:
t = d/60
So the inverse function is t(d) = d/60.
To find t(160), we substitute 160 for d in the equation t(d) = d/60:
t(160) = 160/60
t(160) = 2.67 (rounded to 1 decimal place)
Therefore, if the car travels 160 miles, it will take approximately 2.7 hours to cover that distance.

The calculated volume of the prism with the dimension 6 1/2 cm by 2 1/2 cm by 2 1/2 cm is 325/8 cm³
Calculating the volume of the prism?To find the volume of a rectangular prism, we need to multiply its length, width, and height.
In this case, the length is 6 1/2 cm, the width is 2 1/2 cm, and the height is also 2 1/2 cm.
First, we need to convert the mixed numbers to improper fractions.
6 1/2 = 13/2
2 1/2 = 5/2
Now, we can multiply the three values together to find the volume:
Volume = length x width x height
Volume = (13/2) x (5/2) x (5/2)
Volume = (13 x 5 x 5) / (2 x 2 x 2)
Volume = 325/8

3. A cannonball is fired into the air with an initial vertical velocity of 128 feet per second. The release point is 6 feet above the ground. The function h =-16t2+128t+6 represents the height h (in feet) of the cannonball after t seconds.
a find the height of the cannonball each second after it is fired
b use the graph of the model to determine how long the cannonball is in the air
a) After one second in the air, the cannonball's height is:
[tex]h = -16(1)^2 + 128(1) + 6 = 118 feet[/tex]
b) 8 seconds pass while the cannonball is in the air (from when it is fired until it hits the ground).
what is velocity?The pace at which an object's position changes in relation to a frame of reference and time is what is meant by velocity. Although it may appear sophisticated, velocity is just the act of moving quickly in one direction. Since it is a vector quantity, the definition of velocity requires both magnitude (speed) and direction. Its SI equivalent is the meter per second (ms-1). A body is considered to be accelerating if its velocity changes, either in magnitude or direction.
from the question:
a) We can enter values of t into the equation[tex]h = -16t^2 + 128t + 6[/tex] and evaluate to obtain the height of the cannonball each second after it is shot.
The height of the cannonball at time t = 0 is as follows:
[tex]h = -16(0)^2 + 128(0) + 6 = 6 feet[/tex]
When t = 1, the cannonball has been in the air for 1 second, so its height is:
[tex]h = -16(1)^2 + 128(1) + 6 = 118 feet[/tex]
b) The graph of the function [tex]h = -16t^2 + 128t + 6[/tex] can be used to calculate how long the projectile has been in the air. When the cannonball is six feet above the ground, it is said to be in the air. The values of t must be determined when h is larger than or equal to 6.
Finding the values of t where the graph crosses the line y = 6 is one technique to do this. Another is to graph the function. Another method is to solve for t while setting h = 6:
[tex]-16t^2 + 128t + 6 = 6[/tex]
[tex]-16t^2 + 128t = 0[/tex]
-16t(t - 8) = 0
t = 0 or t = 8
Hence, the cannonball flies for 8 seconds (from when it is fired until it hits the ground).

LORAN is a long range hyperbolic navigation system. Suppose two LORAN transmitters are located at the coordinates and , where unit distance on the coordinate plane is measured in miles A receiver is located somewhere in the first quadrant. The receiver computes that the difference in the distances from the receiver to these transmitters is 180 miles.
What is the standard form of the hyperbola that the receiver sits on if the transmitters behave as foci of the hyperbola?
[tex]$$16[(x_2 - x_1)^2 + (y_2 - y_1)^2]x^2 - 32(x_2 - x_1)x^3 + 16(x_2 - x_1)[(y_2 - y_1)^2 + (x_2 - x_1)^2 - 180^2]x + 16[(y_2 - y_1)^2 + (x_2 - x_1)^2]y^2 - 32(y_2 - y_1)y^3 + 16(y_2 - y_1)[(y_2 - y_1)^2 + (x_2 - x_1)^2 - 180^2]y + [(x_2 - x_1)^2 + (y_2 - y_1)^2 - 180^2]^2 = 0$$[/tex]
this is the standard form of the hyperbola that the receiver sits on if the transmitters behave as foci of the hyperbola.
What is hyperbola ?
A hyperbola is a type of conic section that has two separate parts, called branches, which are mirror images of each other. It is defined as the set of all points in a plane, such that the difference between the distances from two fixed points, called foci, is a constant. Hyperbolas have many applications in science, engineering, and mathematics.
Given two LORAN transmitters located at the coordinates [tex]$(x_1, y_1)$[/tex] and [tex](x_2, y_2)$[/tex], where unit distance on the coordinate plane is measured in miles.
Let the coordinates of the receiver be [tex](x,y)$.[/tex]
The distance from the receiver to the first transmitter is given by [tex]$\sqrt{(x - x_1)^2 + (y - y_1)^2}$[/tex], and the distance from the receiver to the second transmitter is given by [tex]\sqrt{(x - x_2)^2 + (y - y_2)^2}$.[/tex]
Since the difference in the distances from the receiver to these transmitters is 180 miles, we have:
[tex]$$\sqrt{(x - x_1)^2 + (y - y_1)^2} - \sqrt{(x - x_2)^2 + (y - y_2)^2} = 180$$[/tex]
Squaring both sides, we get:
[tex]$$(x - x_1)^2 + (y - y_1)^2 - 2\sqrt{(x - x_1)^2 + (y - y_1)^2} \sqrt{(x - x_2)^2 + (y - y_2)^2} + (x - x_2)^2 + (y - y_2)^2 = 180^2$$[/tex]
Rearranging, we get:
[tex]$$(x - x_1)^2 + (y - y_1)^2 - (x - x_2)^2 - (y - y_2)^2 = 4\sqrt{(x - x_1)^2 + (y - y_1)^2} \sqrt{(x - x_2)^2 + (y - y_2)^2} - 180^2$$[/tex]
Using the identity $a^2 - b^2 = (a + b)(a - b)$, we can simplify the left-hand side as:
[tex]$$4x(x_2 - x_1) + 4y(y_2 - y_1) = 4\sqrt{(x - x_1)^2 + (y - y_1)^2} \sqrt{(x - x_2)^2 + (y - y_2)^2} - 180^2$$[/tex]
Squaring both sides again and simplifying, we get:
[tex]$$16[(x_2 - x_1)^2 + (y_2 - y_1)^2]x^2 - 32(x_2 - x_1)x^3 + 16(x_2 - x_1)[(y_2 - y_1)^2 + (x_2 - x_1)^2 - 180^2]x + 16[(y_2 - y_1)^2 + (x_2 - x_1)^2]y^2 - 32(y_2 - y_1)y^3 + 16(y_2 - y_1)[(y_2 - y_1)^2 + (x_2 - x_1)^2 - 180^2]y + [(x_2 - x_1)^2 + (y_2 - y_1)^2 - 180^2]^2 = 0$$[/tex]
this is the standard form of the hyperbola that the receiver sits on if the transmitters behave as foci of the hyperbola.
Therefore, [tex]$$16[(x_2 - x_1)^2 + (y_2 - y_1)^2]x^2 - 32(x_2 - x_1)x^3 + 16(x_2 - x_1)[(y_2 - y_1)^2 + (x_2 - x_1)^2 - 180^2]x + 16[(y_2 - y_1)^2 + (x_2 - x_1)^2]y^2 - 32(y_2 - y_1)y^3 + 16(y_2 - y_1)[(y_2 - y_1)^2 + (x_2 - x_1)^2 - 180^2]y + [(x_2 - x_1)^2 + (y_2 - y_1)^2 - 180^2]^2 = 0$$[/tex]

Find the circumference of the circle (use 3.14 for pi). Show your work. Round to the nearest tenth.
The circumference of the circle is 144.44 yards
What is the circumference of the circleThe circumference of a circle is the total distance around the edge of the circle. It's computed using the following formula:
Circumference = 2πr.
where r is the circle's radius and represents the ratio of a circle's circumference to its diameter by a mathematical constant π that roughly equals 3.14159.
We can also use the formula below whenever we have the diameter of the circle given
c = πd
where d is the diameter of the circle (the distance across the circle passing through the center).
From the image given, the circumference of the circle is given as;
c = 2πr
r = 23yd
c = 2 * 3.14 * 23
c = 144.44
