For the given equation find the value a, b, and c, determine the direction in which the parabola opens and determine the y-inter
Y_Kistochka [10]

Answer: Table A

Step-by-step explanation:

The coefficient of x^2 is 1, the coefficient of x is -6, and the constant is 0. This means that a = 1, b = -6, and c = 0.

  • This eliminates tables B and C.

Now, we need to determine if the graph opens up or down to differentiate between A and B. Since the coefficient of x^2 is positive, the graph opens up.

  • Thus the answer is <u>Table A.</u>

1. We can conclude that the result of the division is x-13 with a remainder of 4x-9, or in other notation: x-13+ \frac{4x-9}{x^2+3}. Check the steps in the first image.

3. We can conclude that the result of the division is x^{2} +6x+3 with a remainder of 2, or in other notation: x^{2}+6x+3+ \frac{2}{x-1}. Check the steps in the firts image.

5. We can conclude that the result of the division is x+1 with a remainder of 5, or in other notation: x+1+ \frac{5}{x-4}. Check the steps in the first image.

7. To check if x+4 is a factor of x^{3}+3x^{2}-10x-24, we are going to perform long division. If the result of the long division has no remainder, x+4 is a factor of x^{3}+3x^{2}-10x-24.
Since the result of the long division has no remainder, we can conclude that x+4 is a factor of x^{3}+3x^{2}-10x-24. Check the steps in the second image.

9. To check if x-3 is a factor of x^{3}+3x^{2}-10x-24, we are going to perform long division. If the result of the long division has no remainder, x-4 is a factor of x^{3}+3x^{2}-10x-24.
Since the result of the long division has no remainder, we can conclude that x-4 is a factor of x^{3}+3x^{2}-10x-24. Check the steps in the third image.

10. We can conclude that the result of the synthetic division is -2x^{2}+9x+5. Check the steps in the fourth image.

What fraction of an hour is 56 minutes?<br> Give your answer in its simplest form.
d1i1m1o1n [39]

Answer:

\frac{14}{15}

Step-by-step explanation:

There are 60 minutes in an hour, thus

56 minutes = \frac{56}{60} of an hour

To simplify divide 56 and 60 by 4

56 minutes = \frac{14}{15} ← in simplest form
