graph h(x)=(x-1)^2-9
The graph of h(x) = (x-1)^2 - 9 is a U-shaped parabola that opens upwards, with the vertex at (1, -9), and it extends indefinitely in both directions.
The function h(x) = (x-1)^2 - 9 represents a quadratic equation. Let's analyze the different components of the equation to understand the behavior of the graph.
The term (x-1)^2 represents a quadratic term. It indicates that the graph will have a parabolic shape. The coefficient in front of the quadratic term (1) implies that the parabola opens upwards.
The constant term -9 shifts the graph downward by 9 units. This means the vertex of the parabola will be at the point (1, -9).
Based on this information, we can draw the following conclusions:
The graph will be a U-shaped curve with the vertex at (1, -9).
The vertex represents the minimum point of the parabola since it opens upward.
The parabola will be symmetric with respect to the vertical line x = 1 since the coefficient of the quadratic term is positive.
The graph will extend indefinitely in both directions.
To accurately plot the graph, you can choose several x-values, substitute them into the equation to find the corresponding y-values, and then plot the points on the graph. Alternatively, you can use graphing software or calculators that can plot the graph of the equation for you.
Remember to label the axes and indicate the vertex at (1, -9) to provide a complete representation of the graph of h(x) = (x-1)^2 - 9.

The specified scale factor of the dilation from S to M is 3/2 therefore, the scale factor of the dilation transformation from M to S is 2/3
What is a dilation transformation?A dilation is a transformation in which the lengths of the sides of the image are increased or decreased in the proportion, specified by a scale factor to the dimensions of the pre-image.
The specified scale factor from triangle S to triangle M = 3/2
3/2 = 1.5
Therefore, the length of the sides of triangle M are 1.5 times the lengths of the sides of triangle S
Let L represent the length of a side of triangle S, we get;
The length of the corresponding side on triangle M = 1.5 × L
The scale factor from triangle M to triangle S is found by taking the ratio of the corresponding sides of triangle S and M as follows;
Scale factor, SF, from M to S = Length of a side on triangle S ÷ Length of the corresponding side on triangle
Therefore;
\(SF = \dfrac{L}{1.5\cdot L} = \dfrac{1}{1.5}\)
1.5 = 3/2, therefore;
\(SF = \dfrac{1}{1.5} = \dfrac{1}{\frac{3}{2} } =\dfrac{2}{3}\)
Therefore, the scale factor from M to S is 2/3

Sally made a profit of $2500 after selling stocks for $19000 after 2.5 years. What was her average annual percentage gain?
13.25%
6.06%
3.78%
Sally's average annual percentage gain is approximately 5.26%.
To calculate Sally's average annual percentage gain, we can use the formula:
Average Annual Percentage Gain = (Profit / Initial Investment) * (1 / Time) * 100
Profit = $2500
Initial Investment = $19000
Time = 2.5 years
Substituting the values into the formula:
Average Annual Percentage Gain = (2500 / 19000) * (1 / 2.5) * 100
= (0.1316) * (0.4) * 100
= 5.26

Write an equation that represents the perimeter of triangle. Combine like terms.
Shows a equilateral triangle with 3x on both top sides and 15 on the bottom.
Perimeter of triangle:
If the perimeter of the triangle is 90, what is the value of x?
x+
Answer:
x = 12.5
Step-by-step explanation:
The three sides of the triangle have lengths 3x, 3x, and 15.
The perimeter of the triangle is the sum of the three lengths, and it is 90.
Perimeter = 3x + 3x + 15 = 6x + 15
3x + 3x + 15 = 90
6x + 15 = 90
6x = 75
x = 12.5
Why might young adults,in particular,value credit in case of emergency
Young adults might value credit in case of an emergency for several reasons. Firstly, credit provides financial flexibility, allowing them to access funds quickly when unexpected expenses arise.
This can be essential for covering costs related to medical emergencies, car repairs, or other unforeseen events that may strain their limited savings. Secondly, young adults often have less established financial safety nets than older individuals. They may not have significant savings, insurance policies, or support from family members to fall back on during emergencies. Credit, in this case, acts as a temporary financial cushion, enabling them to manage immediate needs without resorting to high-interest loans or further jeopardizing their financial stability.
Thirdly, responsible use of credit can help young adults build a positive credit history. Demonstrating responsible borrowing and repayment habits will make it easier for them to access more favorable credit terms in the future, such as lower interest rates or higher credit limits. This can prove valuable when making significant purchases, like buying a home or financing higher education.
Lastly, having access to credit can also provide young adults with a sense of financial independence and empowerment. Knowing they have the means to handle emergencies without relying on others can boost their confidence in managing personal finances and help them make more informed financial decisions as they navigate adulthood.

You are playing in the NBA Playoffs and attempt a 3-point shot as the buzzer sounds for the end of the
game, if you make the shot your team wins! Your basketball is is traveling on a path described by the
following function: b(x) = -x2 +1.36x + 2. The net is on a level described by the following function:
n(x) = 3 between (8 < x < 8.5). Will you make the shot and win the playoffs?
You may work alone or in a group of up to 3 students total.
BONUS: How high in the air will the basketball be at its highest point?
UNITS: x is in meters, y is in meters.
The quadratic function for the path of the basketball as it is thrown indicates;
The path of the basketball will not make the shot
The height reached is about 5.24 meters
What is a quadratic function?A quadratic function is a function of the form; f(x) = a·x² + b·x + c, where a ≠ 0, and a, b, c, are numbers.
The function for the path of the basketball is; b(x) = (-1/7)·x² + 1.36·x + 2
The function for the location of the basketball net is; n(x) = 3 and (8 < x < 8.5), where;
n(x) = The vertical height of the basketball
Plugging in the value of the n(x) = b(x), to check if equations have a common solution, we get;
b(x) = n(x) = 3 = (-1/7)·x² + 1.36·x + 2
(-1/7)·x² + 1.36·x + 2 - 3 = 0
(-1/7)·x² + 1.36·x - 1 = 0
(1/7)·x² - 1.36·x + 1 = 0
Solving the above equation, we get;
x = (119 - √(9786))/(25) ≈ 0.803, and x = (119 + √(9786))/(25) ≈ 8.717
Therefore, the x-coordinates of the height of the path of the basketball when the height is 3 meters are 0.803 and 8.717, neither of which are within the range (8 < x < 8.5), therefore, the baseketball will not go through the net and the path will not make the shot.
Bonus; The x-coordinates of the highest point of a quadratic function, f(x) = a·x² + b·x + c is; -b/(2·a)
Therefore, the x-value at the highest point of the equation, b(x) = (-1/7)·x² + 1.36·x + 2 is; x = -1.36/(2 × (-1/7)) = 1.36 × 7/2 = 9.52/2 = 4.76
The height of the highest point is; b(9.52) = (-1/7)·(4.76)² + 1.36·(4.76) + 2 ≈ 5.24 meters
