Function g can be thought of as a translated (shifted) version of f(x) = x^2
The new function's equation is g(x) = (x - 2)² + 6
Given,
The parent function, f(x) = x²
We have to determine the equation for the new function g(x)
Vertical shift:
The parent function is clearly pushed 6 units upward from the graph.
The general formula to increase the c units on the graph is f(x) + c
As a result, by using the rule, the new function g(x)of vertical shift is provided by g(x) = x² + 6
Horizontal shift:
It is clear from the graph that the parent function has been moved 2 units to the right.
To move the graph's c units to the right, follow this basic formula: f(x - c)
Consequently, the new function g(xhorizontal )'s shift is given by g(x) = (x - 2)²
The new function g( x ) is as follows:
The equation results in the new function being shifted 2 units to the right and 6 units upward.
g(x) = (x - 2)² + 6
Therefore, the new function's equation is g(x) = (x - 2)² + 6

(209 kg) moving +1.72 m/s.
What is the velocity of car A after
the collision?
(Unit = m/s)
Remember: right is +, left is -
Enter
After collision, Car A moves with a velocity of 4.1 m/s
Elastic CollisionAn elastic collision is a collision in which there is no net loss in kinetic energy in the system due to the collision. Both momentum and kinetic energy are conserved in an elastic collision. It can be either one-dimensional or two-dimensional. In the real world, perfectly elastic collision is impossible because there is bound to be some energy conversion, however small. However, though there is no change in the linear momentum of the whole system, there is a change in the individual momenta of the involved components, which are equal and opposite in magnitude and cancel each other out and the initial energy is conserved.
The formula of elastic collision is given as
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
Assuming after collision, car B has a velocity of 0m/s
281(2.82) + 209(1.72) = 281 * v + 0
792.42 + 359.48 = 281v
1151.9 = 281v
v = 1151.9 / 281
v = 4.1 m/s

4.43 overweight baggage. suppose weights of the checked baggage of airline passengers follow a nearly normal distribution with mean 45 pounds and standard deviation 3.2 pounds. most airlines charge a fee for baggage that weigh in excess of 50 pounds. determine what percent of airline passengers incur this fee.
The percentage of airline passengers covered by this fee is 85.99%.
If the distribution is normal, use the Z-score formula. For a set of means and standard deviations, the measure's z-score X is given by z-score measures how many standard deviations a measure is from its mean. After finding the Z-score, look at the Z-score table to find the p-value associated with that Z-score. This p-value is the probability that the value of the measure is
less than X, the percentile of X Subtracting 1 from the p-value gives the probability that the value of the measure is greater from X means 46 pounds with a standard deviation of 3.7 pounds.
This is the p-value of Z for X = 50 minus 1 as a
ratio. So the p-value of is 0.8599or 0.8599× 100 = 85.99%
So, 85.99% of the airline passengers pay this fee.

The function h(x) is a translation of 4 units to the left, so the correct options is B.
h(x) = √(x + 4)
What is the rule for function h(x)?We know that h(x) is a transformation on the parent square root function:
f(x) = √x
If we look at the graphs, we can see h(x) is translated 4 units to the left.
Now, for a function f(x), we define a horizontal translation of N units as:
h(x) = f(x + N)
if N < 0, the translation is to the right.
if N > 0, the translation is to the left.
In this case we have a translation of 4 units to the left, then N = 4, so we can write:
h(x)= f(x + 4)
Replacing the function f(x) we get:
h(x) = √(x + 4)

A triangle has two sides of length 12 and 18. What is the smallest possible whole-number length for the third side?
Answer:
7
Step-by-step explanation:
You want the integer length of the shortest third side that will form a triangle with sides 12 and 18.
Triangle inequalityThe triangle inequality requires the sum of any two sides exceed the measure of the third side. If x is the short side, we want ...
x +12 > 18
x > 6 . . . . . . subtract 12
The smallest integer greater than 6 is 7.
The third side must be at least 7 units long.

Additional comment
Some authors write the triangle inequality as a+b≥c. If you use that version, then the shortest side can be 6 units. The resulting "triangle" will have zero area, and will look like a line segment 18 units long.

Answer: A number which is divided by 5, with the result as 50 less than if the number had been divided by 6 would be; -1500
How to solve Algebra Word Problems?
Let the number be x. We are asked that it is divided by 5, and the result is 50 less than if the number had been divided by 6;
(x/6) - (x/5) = 50
Multiply by 30 to get;
5x - 6x = 1500
-x = 1500
x = -1500
Let the older turtle be represented x and the younger one be y.
Todays age,
Older turtle = 11y years
Younger turtle = y years
Also the equation form as;
11y + 24 = 7(y + 24)
11y + 24 = 7y + 168
11y - 7y = 168 - 24
4y = 144
y = 144/4
y = 36
Thus;
Age of older turtle today = 396 years
Age of younger turtle today = 36 years
Therefore,
3(36 + t) = 396 + t
108 + 3t = 396 + t
2t = 292
t = 292/2
t = 146 years

The Correct option is D .
System of linear equations,gives us the result that given system has unique solution such that 13x= 6 or x = 6/13 and y = -40/13 .
If a, b, and c are real numbers, the graph of the equation ax + by = c
is a straight line (unless both a and b are zero), so such an equation is called a linear equation in variables x and y. There are three possible types of solutions to a set of linear equations.
Unique Solution: A system of linear equations has a solution if the graphs intersect at a point.No Solution: If the graph is parallel, the system of linear equations has no solution.Infinitely Many Solutions: There are infinitely many solutions to a system of linear equations if the graph is exactly the same straight line.given system of equations is
2x - y = 4 --(1)
and 5x + 4y = -10 ---(2)
comparing the above equations with linear system , a1 x + b1 y = c1 and a2 x + b2y = c2
we get, a1 = 2 , a2= 5 , b1 = -1 , b2= 4 , c1= 4 ,
c2= -10
Now, the ratio are
a1/a2 = 2/5 ; b1/b2 = -1/4 ; c1/c2= -4/10 = 2/5
=> a1/a2 not equal to b1/ b2
therefore the given system of equations has unique solution.
Now , we find the soltion of given system using Elimination method,
multipling equation (1) by 4 to making same cofficient of y in both equations of system we get
8x - 4y = 16 --(3) and 5x +4y = -10
adding equation (2) from (3) we get,
8x -4y + 5x + 4y = 16 -10 => 13x = 6 => x = 6/13
putting this value of x in (1)
2×6/13 - y = 4 => y = 12/13-4 = -40/13
Hence , unique solution for given system of equations is x= 6/13 , y = -40/13.

Which statement best reflects the solutions of the equation X over X minus one minus one over X -2 equals 2X -5 over X squared minus 3X +2
The statement which best reflects the solutions of the equation; as given in the task content is; x = 3 is a valid solution and x = 2 is an extraneous solution.
What is the solution of the equation?It follows from the task content that the statement which represents the solution of the given equation be determined.
Since the given equation can be written algebraically as follows;
x/(x - 1) - 1/(x - 2) = (2x - 5) / (x² - 3x + 2)
By observation; (x - 1) (x - 2) = x² - 3x + 2.
Therefore, by multiplying through the equation by; x² - 3x + 2; we have;
x (x - 2) - 1 (x - 1) = 2x - 5
x² - 2x - x + 1 = 2x - 5
x² - 5x + 6 = 0.
Hence, the equation above can be solved quadratically so that we have;
(x - 3) (x - 2) = 0.
Therefore, the solution to the given equation is; x = -3 Or x = 2.
However, the solution x = 2 renders the equation undefined, hence, it is not a valid solution but an extraneous solution.
Therefore, the statement which reflects the solutions to the given equation is; x = 3.
