Here is the graph of a quadratic function f.
Select all equations that could define the function f.
Answers
Answer:
A B and D
Step-by-step explanation:
Given the parabola is opening downward, the function has to be negative. Therefore, A B and D are correct.
The following equations could define the given quadratic function.
1. -1(x-1)²+9
4. -x²+2x+8
6. (x+2)(x-4)
What is Parabola?A parabola is a U-shaped curve this is drawn for a quadratic function,
f(x) = ax² + b x + c.
1. The function -1(x-1)²+9 represents a downward-facing parabola.
The vertex of the parabola is at point (1, 9), and it opens downward because the coefficient of the squared term (-1) is negative.
4. The function -x²+2x+8 represents a downward-facing parabola as well.
6. The parabola intersects the x-axis at x = -2 and x = 4.
Hence, the correct answer is options 1, 4, 6.

An online health and medicine company claims that about 50% of Internet users would go to an online sight first for
information regarding health and medicine. A random sample of 1318 Internet users was asked where they will go for
information the next time they need information about health or medicine; 606 said that they would use the Internet. Test
the claim that less than 50% of Internet users get their health questions answered online.
Answers
Answer:
The claim that less than 50% of internet users get their health questions answered online is correct, given that according to the survey, 45.98% of people do.
Step-by-step explanation:
Since an online health and medicine company claims that about 50% of Internet users would go to an online sight first for information regarding health and medicine, and a random sample of 1318 Internet users was asked where they will go for information the next time they need information about health or medicine; 606 said that they would use the Internet, to test the claim that less than 50% of Internet users get their health questions answered online, the following calculation must be performed:
1318 = 100
606 = X
606 x 100/1318 = X
60600/1318 = X
45.978 = X
Therefore, the claim that less than 50% of internet users get their health questions answered online is correct, given that according to the survey, 45.98% of people do.

A: Tomato - 20
B: Cucumber- 9
C: Peas - 27
D: Onion - 6
Answers
Answer:
A(tomatos)
Step-by-step explanation:
So to sovle these, we have to look at the percentage chart, and take the percentage of each thing.
tomato - 30%cucumber - 15%peas - 45%onion - 10%We know that divide these numbers by 100 gets us the amount we can multiply the total by, which gives us our answer.
So tomato is .3, cucumber is .15, peas are .45, and onion is .1.
Now, lets mutiply these nubmers by the 60 and see what we get:
.1*60
=
6
That seems correcdt for the onion
.45 * 60
=
27. That looks correct for peas.
.15 * 60
=
9 That looks correct for cucumber
.3*60
=
18. Thats not 20! So that must be the answer!
Hope this helps!
