Find the coordinates of the vertex of the following parabola using graphing technology. Write your answer as an (x, y) point. y ==2x² - 24r – 56
Answers
The solution of the given equation y ==2x² - 24r – 56 :
(6 , -128)
What is graphing technology?Graph technology aids in the discovery of unknown links in data that cannot be detected or examined using traditional methods. When the broad term graph is introduced as both a topic, it frequently blurs three distinct topics: graph theory, graph analytics, and graph data management.
Why is graphing useful?Graphs and charts are useful visual tools because they deliver information quickly and readily. It is hardly surprising, then, that graphs are widely utilized in print and electronic media. Data can be easier understood when displayed as a graph rather than a table since the graph can illustrate a pattern or comparison.
According to the given equation:y =2x² - 24x – 56
Solving for :
Parabola equation in polynomial form
ax² + bx + c for x = -b/(2a)
a = 2
b = -24
c = -56.
on solving we get
= -(- 24)/2* 2
= 6
The value of x = 6
putting the value of x to get y:
2x² - 24x – 56
2(6)² - 24(6) – 56
-128
the value of y = -128.

which of the following indicates the division property of equality when solving -12x = 48
Answers
From division it is possible to find x= -4.
Linear FunctionAn equation can be represented by a linear function. The standard form for the linear equation is: y= ax+b , for example, y=7x+2. Where:
a= the slope. It can be calculated for [tex]a=\frac{\Delta y}{\Delta x}[/tex] .
b= the constant term that represents the y-intercept.
For the given example: a=7 and b=2.
For solving linear equations, you should organize variables on one side of the equation and the numbers on the other side. When a number or variables change side, its signal also is changed.
Therefore for -12x=48, you should follow the steps below

Step-by-step explanation:
Answer:
y = 3x² + 6x - 45
Step-by-step explanation:
given roots x = a and x = b then the factors are (x - a) and (x - b)
then the quadratic is the product of its factors
y = a(x - a)(x - b) ← a is a multiplier
here x = - 5 and x = 3 with a = 3 , then factors are
(x - (- 5)) and (x - 3) , that is (x + 5) and (x - 3) , then
y = 3(x - 3)(x + 5) ← expand factors using FOIL
y = 3(x² + 2x - 15) ← distribute parenthesis by 3
y = 3x² + 6x - 45

Determine if the conjecture is true or false.
If False give a counterexample.
Answers
a = 1, b = 2 is a counterexample, and with that, we conclude that the conjecture is false.
Is the conjecture true or false?Here we have the conjecture:
"For any two integers a and b, (a - b)^2 = (a^2 - b^2)"
Notice that if we find a single pair of integers a and b such that the equality in the conjecture is false, then we have found a counterexample and that is enough to conclude that the conjecture is false.
If we define=
a = 1
b = 2
Replacing that in the equation of the conjecture we get:
(1 - 2)^2 = (1^2 - 2^2)
(-1)^2 = 1 - 4
1 = -3
This is false, then a = 1, b = 2 is a counterexample, and with that we conclude that the conjecture is false.

Find the 96th term of the arithmetic
sequence -3, -14, -25,
Answers
The 96th term of this arithmetic sequence is -1059.
In an Arithmetic Progression (AP), the nth term is given by the formula-
a9 = a + (n-1)d
where a = first term of the AP
d = common difference
Here, we are given an AP-
-3, -14, -25
Here a = -3
and d = -14 + 3 = -11
Let the 96th term of the AP be a96
Therefore, according to the formula for finding the nth term of an AP, we get-
a96 = a + (96-1)d
a9 = a + 95d
Substituting the values of a and d given in the question-
a96 = -3 + 96(-11)
a96 = -3 - 1056
a96 = -1059
Thus, the 96th term of the arithmetic sequence is -1059.

We need to find the constant of proportionality.
The constant of proportionality is the ratio that relates two given values in what is known as a proportional relationship.
We know that:
Robins ∝ Cardinals
Robins = K × Cardinals
K = the constant of proportionality
15 = k (5)
k = 3

Answers
The piecewise function for the discounted price of the purchase is given by:
D(x) = 0.96x, 300≤x<1,000.D(x) = 0.95x, 1,000≤x<3,000.D(x) = 0.94x, 3,000≤x<5,000.D(x) = 0.9x, 5,000≤x.What is a piecewise function?A piecewise function is a function that has different definitions, depending on the input.
For $300≤x<$1,000, the discount is of 4%, hence the discounted price is 96% of the original price, that is:
D(x) = 0.96x, 300≤x<1,000
For $1,000≤x<$3,000, the discount is of 5%, hence the discounted price is 95% of the original price, that is:
D(x) = 0.95x, 1,000≤x<3,000.
For $3,000≤x<$5,000, the discount is of 6%, hence the discounted price is 94% of the original price, that is:
D(x) = 0.94x, 3,000≤x<5,000.
For $5,000≤x, the discount is of 10%, hence the discounted price is 90% of the original price, that is:
