Evaluate the expression 6x-x2 for x= 0, 1, 2, 3, 4, 5, and 6. Use your results to fill in the table. Describe any pattern that you see.
The values of the expression [tex]6x - x^2[/tex] are evaluated for x values from 0 to 6 and a symmetrical pattern around x = 3 is observed, with the expression value increasing up to x = 3 and then decreasing symmetrically.
The expression to evaluate is [tex]6x - x^2[/tex]. Let's plug in each value of x into the expression and see the result.
For x = 0: the expression becomes [tex]6(0) - (0)^2[/tex] = 0.For x = 1: the expression becomes [tex]6(1) - (1)^2[/tex]= 5.For x = 2: the expression becomes [tex]6(2) - (2)^2[/tex] = 8.For x = 3: the expression becomes [tex]6(3) - (3)^2[/tex] = 9.For x = 4: the expression becomes [tex]6(4) - (4)^2[/tex] = 8.For x = 5: the expression becomes [tex]6(5) - (5)^2[/tex] = 5.For x = 6: the expression becomes [tex]6(6) - (6)^2[/tex] = 0.The pattern we can observe from filling the table is that the value of the expression increases until x = 3 and then decreases symmetrically.
At x = 0 and x = 6, the expression has a value of 0, creating a symmetry about the axis x = 3, which is the vertex of the parabola represented by the given quadratic expression.

Sarah mailed her computer to Store B for repairs. Her bill was: Total Cost of Computer Repair = $1,444.50 Shipping = 2 percent of Total Cost If Sarah wanted to include a 15 percent gratuity, based on the total cost of the computer repair, excluding shipping, how would you find her new total cost?
Answer:
The total repair cost for each store is the cost of repairs added to the sales tax. The amount of money saved will be the difference between the two total costs.
Step-by-step explanation:
Endogeneity answers
The new total cost Sarah has to pay, including the 15% gratuity is $1690.07. This is calculated by adding her repair cost, shipping fee, and gratuity together.
Explanation:The total cost that Sarah has to pay can be calculated by adding up the cost of computer repair, the cost of shipping, and the gratuity she wants to include. The cost of shipping is 2 percent of the total cost of computer repair, so it would be $1,444.50 * 0.02 = $28.89. The gratuity Sarah wants to pay is 15 percent of the total cost of the computer repair (excluding the cost of shipping) which is $1,444.50 * 0.15 = $216.68.
Adding all these together: $1444.50 (Cost of Repair) + $28.89 (Shipping) + $216.68 (Gratuity) gives us a total cost of $1690.07. This will be the new total cost Sarah has to pay.

The expression 53(1+x) represents the total cost of a meal including the tip. What do the different parts of the expression represent? Drag the parts of the expression into the boxes to match each description. cost of meal tip percentage
The correct answers are:
53 is the cost of the meal and x is the tip percentage.
Explanation:
When we add a tip to the total cost of a meal, we pay 100% of the cost of the meal plus an additional amount. In decimal form, this gives us 1 + the decimal for the tip percent. This is the (1+x) in this expression.
We multiply this (1+x) by the cost of the meal. This means that in this case, 53 is the cost of the meal.

What is Number system?A number system is defined as a system of writing to express numbers.
Number line is a picture of a graduated straight line that serves as visual representation of the real numbers.
Let the x point is at minus two and y is at two
The distance will be always positive
As we count the number of humps for each unit we get four.
So the distance is 4 units.
The distance between two points is the length of the line joining the two points
|-2-2|=4
Hence, 4 units is the distance between these two points represent

A model for the path of a toy rocket is given by h= -68t - 4.9t^2
How long does it take the rocket to hit the ground? How high was the rocket at 2 seconds? What is the maximum height of that rocket and how long does it take that rocket to reach it's maximum height?
The duration for the rocket to hit the ground, its height at 2 seconds, and its maximum height can be calculated using the given quadratic equation for height over time. The maximum height is determined by finding the vertex of the parabola.
Explanation:To determine how long it takes the toy rocket to hit the ground, we need to set the equation for height h to zero and solve for time t. The model for the path of a toy rocket is given by [tex]h = -16t2 - 4.9t2[/tex]. To solve for t, we factor the right side:
[tex]h = -4.9t(16 + t)[/tex]
Since h = 0 when the rocket hits the ground, we set [tex]-4.9t(16 + t) = 0[/tex] and solve for t. There are two solutions: t = 0 (when the rocket is launched) and the positive solution which is when the rocket hits the ground. We disregard the solution t = 0 and solve for the positive solution to find out how long it takes to hit the ground.
To find out how high the rocket was at 2 seconds, we simply plug t = 2 into the original equation:
[tex]h = -16(2)2 - 4.9(2)2[/tex]
And solve for h to get the height at 2 seconds.
To determine the maximum height of the rocket, we need to find the vertex of the parabola represented by the given equation, which is a quadratic function of t. Since the coefficient in front of t2 is negative, the vertex will give us the maximum height. The time it takes to reach the maximum height is given by t = -b/2a, where a and b are coefficients from the equation [tex]h(t) = at2 + bt + c.[/tex] In this case, a = -4.9 and b = -68.
The calculations must be done to find the precise values for the time to hit the ground, the height at 2 seconds, and the maximum height of the rocket, along with the time it takes to reach it.

A large bag contains 12/15 pound of granola how many 1/3 pound bags can be filled with this amount of granola how much granola is left over
TO get the number of bags, we simply get the quotient, that is:
(12 / 15 pounds) / (1 / 3 pounds) = 2.4 bags
Since bags cannot be decimal, so it can only fill 2 bags. The left over is 0.4 or:
0.4 * (1/3) = (2/5) * (1/3) = 2/15 pounds
Answer:
2 bags filled, left over is 2/15 pounds of granola
Answer: 2 bags can be filled and [tex]\dfrac{2}{5}[/tex] pound of granola will be left over.
Step-by-step explanation:
Given : A large bag contains [tex]\dfrac{12}{15}[/tex] pound of granola.
The number of bags can be filled with [tex]\dfrac{1}{3}[/tex] pound of granola in each bag will be :-
[tex]\dfrac{12}{15}\div\dfrac{1}{3}\\\\=\dfrac{12}{15}\times\dfrac{3}{1}=\dfrac{12}{5}\\\\=2\dfrac{2}{5}[/tex]
Thus, the number of bags = 2
The amount of granola left=[tex]\dfrac{2}{5}[/tex] pound
