What is unique about Pythagorean triples? A The squares of the three sides add up to 100. B The length of each side is a perfect square. C The length of each side is a whole number. D The squares of the three sides are multiples of 3.
Final answer:
Pythagorean triples are sets of three whole numbers that form the sides of a right triangle and satisfy the Pythagorean theorem, a² + b² = c².
Explanation:
Pythagorean triples are unique because they consist of three whole numbers that satisfy the Pythagorean theorem.
Specifically, the squares of the two shorter sides (a and b), when added together, equal the square of the longest side (the hypotenuse, c). That is, a² + b² = c² holds true for these numbers.
Answering the student's question, the characteristic that is unique about Pythagorean triples is: C) The length of each side is a whole number.
This means that all three sides of the right triangle are integers, which is helpful in various mathematical and practical applications. Examples of Pythagorean triples include (3, 4, 5) and (5, 12, 13).

A toy rocket was shot into the air. The graph below represents the height over the time of the rocket. Which of the following are true? Select all that apply.
A. The rocket was launched from a platform 4.9 feet above the ground
B. The rocket reached a maximum height of 59 feet
C. It took the rocket 3.5 seconds to reach its maximum height
D. The rocket landed after 34 seconds
E. The equation that represents the rocket’s height over time has two solutions
The correct statements are:
- B. The rocket reached a maximum height of 59 feet.
- C. It took the rocket 3.5 seconds to reach its maximum height.
- E. The equation that represents the rocket’s height over time has two solutions.
To determine which statements about the rocket's flight are true, analyze the given graph.
1. Statement B: The rocket reached a maximum height of 59 feet.
- This statement is true. The highest point on the graph is marked as (3.5, 59), indicating that the maximum height of the rocket was 59 feet.
2. Statement C: It took the rocket 3.5 seconds to reach its maximum height.
- This statement is true. The coordinates (3.5, 59) show that the rocket reached its maximum height at 3.5 seconds.
3. Statement E: The equation that represents the rocket’s height over time has two solutions.
- This statement is true. The parabolic path of the rocket implies a quadratic equation. A quadratic equation typically has two solutions, which correspond to the times when the rocket is at ground level (height = 0). From the graph, we see the rocket starts at (0, 0) and lands at (6.9, 0), confirming two solutions.
Verifying the incorrect statements:
1. Statement A: The rocket was launched from a platform 4.9 feet above the ground.
- This statement is false. The graph shows that the rocket was launched from the origin point (0, 0), meaning it was launched from ground level, not 4.9 feet above the ground.
2. Statement D: The rocket landed after 34 seconds.
- This statement is false. The graph indicates the rocket landed at 6.9 seconds, not 34 seconds.
The correct options are:
A. The rocket was launched from a platform 4.9 feet above the ground.
B. The rocket reached a maximum height of 59 feet.
C. It took the rocket 3.5 seconds to reach its maximum height.
D. The rocket landed after 34 seconds.
E. The equation that represents the rocket's height over time has two solutions.
To determine the validity of each statement, we must analyze the graph of the rocket's height over time. Here is the logical reasoning behind each option:
A. The rocket was launched from a platform 4.9 feet above the ground.
This statement is true if the graph's vertical intercept (the height at time zero) is 4.9 feet. The vertical intercept is the starting height of the rocket before it is launched.
B. The rocket reached a maximum height of 59 feet.
This statement is true if the graph reaches a maximum value of 59 feet at some point in time. This would be the peak of the graph, where the height is greatest.
C. It took the rocket 3.5 seconds to reach its maximum height.
This statement is true if the time at which the graph reaches its maximum height is 3.5 seconds. This is the horizontal coordinate of the peak of the graph.
D. The rocket landed after 34 seconds.
This statement is true if the graph returns to the horizontal axis (height of zero) at 34 seconds. This would indicate that the rocket has returned to the ground.
E. The equation that represents the rocket's height over time has two solutions.
This statement is true if the graph intersects the horizontal axis at two distinct points. The first intersection represents the launch point (time zero), and the second intersection represents the landing point. The fact that there are two intersections implies that the equation has two solutions.
Use the parabola tool to graph the quadratic function. f(x)=2x2+12x+16
Answer:
Step-by-step explanation:
To obtain the graph of a parabola, three data are necessary: the vertex (the vertex is the highest or lowest point of the graph corresponding to the parabola and there it is on the plane of symmetry of the parabola), the roots ( those values of x for which the expression is 0. Graphically, the roots correspond to the abscissa of the points where the parabola cuts the x-axis.) and the concavity.
Being f(x)=ax²+bx+c, you can see that, in this case, a=2, b=12 and c=16. So:
Vertex= for your calculation, [tex]xv=\frac{-b}{2*a}=\frac{-12}{2*2}[/tex], so xv=-3. Now that you know x, all you have to do is enter its numerical value into the original formula to find yv. yv=2*(-3)²+12*(-3)+16. Then yv=-2Roots: The roots are calculated using the expression: [tex]x1,x2=\frac{-b+-\sqrt{b^{2}-4*a*c } }{2*a}[/tex]. Replacing the values that you have:[tex]x1,x2=\frac{-12+-\sqrt{12^{2}-4*2*16 } }{2*2}[/tex] Solving, you obtain x1=-2 and x2=-4Concavity: If a> 0 (positive) the parabola is concave or pointed upwards, while if a <0 (negative) the parabola is convex or pointed downwards. In this case a = 2, so the parabola opens upward, being concave.In this way, the graph shown in the attached image is obtained.

Nicole uses 3 cups of vinegar and her salad dressing recipe how much vinegar with Nicole used to make 3/4 of recipe
Final answer:
Nicole will need 2 1/4 cups of vinegar to make 3/4 of her salad dressing recipe, as you multiply the total amount (3 cups) by 3/4.
Explanation:
Nicole uses 3 cups of vinegar for her full salad dressing recipe. To make 3/4 of the recipe, you would calculate three-quarters of the total amount of vinegar used. Simply multiply 3 cups by 3/4 to find out how much vinegar Nicole would need.
The calculation is as follows:
3 cups × 3/4 = 9/4 cups9/4 cups can be simplified to 2 1/4 cupsThus, Nicole will need 2 1/4 cups of vinegar to make three-quarters of her salad dressing recipe.

Let f(x)=25x2−2 . The function g(x) is a vertical stretch of f(x) by a factor of 2. What is the equation of g(x)?
When the function f(x)=25[tex]x^2[/tex]−2 is vertically stretched by a factor of 2 to create the function g(x), the resulting equation is g(x) = 50[tex]x^2[/tex]−4.
Explanation:The equation of g(x) can be found by vertically stretching f(x) by a factor of 2. Since f(x) = 25[tex]x^2[/tex] - 2, we can multiply the function by 2 to get g(x) the equation:
The function g(x) is described as a vertical stretch of the function f(x) by a factor of 2. If f(x)=25[tex]x^2[/tex]−2, a vertical stretch implies that we multiply all y-coordinates by the given factor, which is 2 in this case. Therefore, g(x) will be 2*f(x).
This gives us:
g(x) = 2*(25[tex]x^2[/tex] −2)
Expand this:
g(x) = 50[tex]x^2[/tex]−4
So, the equation of g(x) after the vertical stretch of f(x) by a factor of 2 is g(x) = 50[tex]x^2[/tex] −4.

The equation of g(x), which is a vertical stretch of f(x) = 25x² - 2 by a factor of 2, is g(x) = 50x² - 4.
To solve this, we need to apply a vertical stretch to the function f(x).
A vertical stretch by a factor of 2 means multiplying the entire function f(x) by 2.
Given :
f(x) = 25x² - 2
we multiply it by 2:
g(x) = 2 * (25x² - 2)
g(x) = 50x² - 4
So, the equation of g(x) is g(x) = 50x² - 4.
