based off of the graph which of the following statements are true. select all that apply
Answers
The correct options are A, D, and G.
Correct statements about the graph are:
A. It has a minimum.
D. Vertex at (-1, -9).
G. Y-intercept at (0, -8).
To determine the truth of the statements given about the graph, we will analyze the graph step by step:
1. **Identify the Vertex**: The vertex of a parabola is the highest or lowest point of the graph, depending on whether it opens upwards or downwards. This graph opens upwards, so the vertex will be the minimum point.
2. **Find the Vertex**: We need to locate the vertex on the graph by looking for the point where the graph changes direction.
3. **Check for Maximum or Minimum**: Since this parabola opens upwards, it will have a minimum point but not a maximum.
4. **Determine the Zeros**: Zeros are the points where the graph crosses the x-axis. These are also known as the roots or solutions of the quadratic function when set to zero.
5. **Locate the Y-Intercept**: The y-intercept is the point where the graph crosses the y-axis.
6. **Examine the Solutions**: The solutions of the quadratic function are the x-coordinates of the zeros of the function.
7. **Assess the Y-Intercept**: We will find the y-coordinate of the point where the graph intersects the y-axis.
Now, let's examine the graph based on these steps:
A. **The graph has a minimum** - True. The parabola opens upwards, which means it has a minimum point where the vertex is located.
B. **The graph has a maximum** - False. Since the graph opens upwards, it does not have a maximum point; the vertex represents a minimum.
C. **The graph has zeros of -4 and 2** - False. The zeros of the graph (where it crosses the x-axis) appear to be different from -4 and 2, as the graph does not touch the x-axis at these points.
D. **The vertex is located at (-1,-9)** - True. By looking at the graph, it appears that the vertex, which is the minimum point, is indeed at the point (-1,-9).
E. **The graph has y-intercepts at (-4,0) and (2,0)** - False. A graph can only have one y-intercept, which is where it crosses the y-axis. The points given are actually x-intercepts or zeros of the function.
F. **The solution of the quadratic function represented by the graph is (-1,-9)** - False. The solution to a quadratic function is typically the x-values where the function crosses the x-axis (the zeros). The vertex is not the solution to the function; it is simply the minimum or maximum point.
G. **The y-intercept of the graph is (0,-8)** - True. The y-intercept is where the graph crosses the y-axis, which appears to be at (0,-8) according to the graph.
Hence, the correct statements are A, D, and G. The graph has a minimum at the vertex (-1, -9) and a y-intercept at (0, -8). It does not have a maximum, and the zeros are not at -4 and 2 as stated in option C. The solutions to the quadratic function would be the x-values of the zeros, not the vertex coordinates.
The complete question is here:
Which of the following statements are true about the graph? Check all that apply.
(GRAPH IS GIVEN BELOW)
A. The graph has a minimum.
B. The graph has a maximum.
C. The graph has zeros of -4 and 2 .
D. The vertex is located at (-1,-9).
E. The graph has y-intercepts at (-4,0) and (2,0).
F. The solution of the quadratic function represented by the graph is (-1,-9).
G. They-intercept of the graph is (0,-8).
The statements that are true from the graph are:
A. The graph has a minimum. D. The vertex is located at (-1,-9). G. The y-intercept of the graph is (0,-8).Why are the statements true ?
There is a vertex on the graph, which implies that there is either a minimum or maximum point. In this case, since the vertex is shown, it indicates a minimum point on the graph.
The vertex of a quadratic function in the form y = ax ² + bx + c is given by the coordinates (-b / 2a, f(-b/2a)), where a, b, and c are coefficients of the quadratic equation.
The y-intercept is the point where the graph crosses the y-axis, and it occurs when x = 0. This is shown to be the point ( 0, - 8 ).
The full question is:
Based off of the graph which of the following statements are true. select all that apply
A. The graph has a minimum.
B. The graph has a maximum.
C. The graph has zeros of -4 and 2 .
D. The vertex is located at (-1,-9).
E. The graph has y-intercepts at (-4,0) and (2,0).
F. The solution of the quadratic function represented by the graph is (-1,-9).
G. They-intercept of the graph is (0,-8).

Explanation:
The inputs are x = -3, x = -1, x = 1, x = 5. They are the first coordinate listed of each point. We don't have any x values repeating so this means we have a function. Each input leads to exactly one output which is what choice B is stating. The domain is the set of allowed inputs, or x values. The range is the set of possible y outputs.
If we had something like (1,2) and (1,5) then the input x = 1 leads to more than one output (y = 2 and y = 5). This example means we don't have a function
If you graph the points (-3, -2), (-1,0), (1,0) and (5,-2) as shown in the attached image, then you'll notice that it is impossible to pass a single line through more than one point. Therefore this graph passes the vertical line test visually proving we have a function.
Going back to the example with (1,2) and (1,5), plotting these two points leads to the vertical line test failing implying we don't have a function.
jacquie hired a contractor to install a tile floor in her laundry room which measures 10.5 feet by 8 feet. the contractor informed her that the tiles cost $4.75 a square foot, he would charge $22 per hour, and it would take him 7.5 hours to complete the job. when the job was done, jacquie received a bill in the amount of $659.12 from the contractor which included an 8% sales tax. is the amount on the bill correct?
Answers
Cost of Area = (10.5 ft)(8 ft)($4.75) = $399
Cost of Hourly Labor = ($22/h)(7.5 h) = $165
Sum = $399 + $165 = $564
Cost of tax = $564(0.08) = $45.12
Total Cost = $564 + $45.12 = $609.12
So, the amount of the bill is incorrect.

Lisa can run a mile in 7 minutes. at that rate of speed how long would it take her to run 2 kilometers
Answers
It would take Lisa approximately 8.669 minutes to run 2 kilometers at her rate of speed.
Explanation:To find out how long it would take Lisa to run 2 kilometers, we need to convert the distance she can run in a mile to kilometers. Since there are 1.60934 kilometers in a mile, we multiply the time it takes her to run a mile (7 minutes) by the conversion factor (1.60934 kilometers/mile). This gives us the time it would take her to run 1.60934 kilometers. To find the time it would take her to run 2 kilometers, we can set up a proportion:
Calculating this gives us x ≈ 8.669 minutes. Therefore, it would take Lisa approximately 8.669 minutes to run 2 kilometers at her rate of speed.

Answers
To solve this problem, we use the z statistic. The z formula is:
z = (x – u) / s
where x is lakers score = 101.7, u is Celtics score = 99.2, s is standard dev = 10.5
z = (101.7 – 99.2) / 10.5 = 0.24
using the normal distribution table at z = 0.24, the P value is:
P (z = 0.24) = 0.5984 = 59.84%

Explanation:In this question, we are given that Patrick has a 600-meter spool of yarn. He used 8.9 minutes of yarn to make a hat. We need to determine if he has enough yarn left to make a scarf that uses 350 meters of yarn.

Let's calculate:
Amount of yarn used for the hat: 8.9 minutesAmount of yarn left: 600 - 8.9 = 591.1 metersAmount of yarn needed for the scarf: 350 metersSince the amount of yarn left (591.1 meters) is greater than the amount needed for the scarf (350 meters), Patrick has enough yarn left to make the scarf.
