Quadratic functions heeeeeellllppp

Mathematics
1 answer:
anzhelika [568]3 years ago
6 0

Answer:

See below

Step-by-step explanation:

Remember that quadratic functions are parabolas when graphed.  The solutions are where the parabola crosses the x-axis.

1.   The vertex of the parabola in f(x) is (0, 9) which is above the x-axis and the parabola opens up.  So the parabola does not cross the x-axis.  Therefore the solutions are imaginary.

2.  The vertex of the parabola in g(x) is (9, 0) which is on the x-axis and parabola opens up.  Therefore, there is a double solution.

3.  The vertex of the parabola in h(x) is (-1, -9) which is below the x-axis and the parabola opens up.  Therefore, there are two real solutions.

I know this is a long explanation, but that is a way of looking at the problem.

Using Triangle Similarity Theorems (6)
Fantom [35]

Answer:

DC = 3

Step-by-step explanation:

Based on triangle similarity theorem, we would have the following equation:

\frac{AD}{AC} = \frac{AE}{AB}

Plug in the values

\frac{9}{9 + DC} = \frac{12}{12 + 4}

\frac{9}{9 + DC} = \frac{12}{16}

\frac{9}{9 + DC} = \frac{3}{4}

Cross multiply

3(9 + DC) = 9×4

27 + 3DC = 36

Subtract 27 from each side

3DC = 36 - 27

3DC = 9

Divide both sides by 3

DC = 9/3

DC = 3

explain why we cannot construct such an interval using the normal approximation. what might go wrong if we constructed the confi
Lyrx [107]

Null Hypothesis, H_{0}: The heart transplant operation had no impact on the patient's survival rates. Alternative Hypothesis, H_{A}: It was asserted that recipients of heart transplants had a higher chance of surviving than recipients of organs from other donors.

The large distribution from binomial, Poisson, etc. is approximated by the normal distribution. Furthermore, the variables are discrete and few, and we are working with counted data rather than real observations. Chi-square distribution should be used in the current scenario. We can determine if the two groups are the same or different by using the chi-square test. As a result, a confidence interval cannot be created.

In other words, the Null Hypothesis is true if the average for the two groups (control and treatment) is equal. In the alternative theory, The averages for the two groups (control and treatment) are different.
