The graph of a quadratic function is shown on the grade.

Mathematics

Answer:

C ( h(x) = x^2 - 6x)

Step-by-step explanation:

Assuming that the function has a slope of 1 (none of the answer choices show a different slope, for all of the coefficients of x^2 are 1) the easiest way to solve this problem would be to find the function for the graph instead of inputting points from the graph into each of the function. (you could do that if you weren't sure.) To get a function from the graph, we first have to find the vertex and enter it into this vertex form function:

h(x) = (x - a )^2 - b

(there are other ways, but finding the vertex and putting the function in vertex form and then simplifying is the easiest way in this situation.) Looking at the graph, we can tell that the vertex of the function is (3, -9). Using the fact that h(x) = (x - a )^2 - b works for the vertex (-a, b), we can conclude that the function is

h(x) = (x - 3)^2 - 9.

This is not an answer! We have to simplify (x - 3)^2 - 9 to answer the question.  By squaring x - 3, we get:

x^2 - 6x + 9 - 9 =

x^2 - 6x.

Therefore, the answer is:

C (h(x) = x^2 - 6x).

I have two weeks to do 55% of my math and 10% of my english in Edgeenuity, is this do-able?
aleksley [76]

Answer:

Yes , depends on will power .

Step-by-step explanation:

Look , 55% of maths means more than your half of the syllabus . and that too in 2weeks . Sometimes it happens , when you target a very big goal , u end up ignoring small and crucial things . when it comes to learning everyone should be patient and always learn step by step . you ask _ you can do or not ? yes YOU can definitely . but when it comes to understand and analys - "how much that study was helpful" then the answer should be "100% helpful " . but if its not , then what's the need of even studying that ? . At the end of the day we all are studying to learn not to conpelete syllabus .

Am just saying , take your time - go through each chapter , eaxh topic deeply so that it would be helpful in other classes too .

<em>At the end of the day - Quality matters not quantity :)</em>

What is the answer of this question?​
polet [3.4K]

Answer:

116

Step-by-step explanation:

8.2 / 2 = 4.1

a = \sqrt{7^{2}-4.1^{2} } = 5.6736

0.5 x 8.2 x 5.6736 = 23.2618

23.2618 x 5 = 116.309 = 116
