How do you find the equation of a parabola given two x intercepts

1 answer:

4 0

Let's assume that the parabola has the following intersections with the x axis:
x1 = p
x2 = q
To find the equation of the parabola, we write the following product of binomials:
(x-p) (x-q) = 0
Where,
p, q: intersections with the x axis.
When developing the product of binomials, we obtain the equation of the parabola.
Answer:
(x-p) (x-q) = 0

I have many students are represented in the data set?

nalin [4]

Answer:

a) 19 students

b) the mean 3 9/19

the median 3

the mode 3

c) the range 6

Step-by-step explanation:

The data set shows that

0 points gets 1 student,

1 point gets 1 student,

2 points get 2 students,

3 points get 6 students,

4 points get 4 students,

5 points get 3 students and

6 points get 2 students.

a) There are 1+1+2+6+4+3+2=19 students.

b) The mean is

$\dfrac{1\cdot 0+1\cdot 1+2\cdot 2+6\cdot 3+4\cdot 4+3\cdot 5+2\cdot 6}{19}=\dfrac{66}{19}=3\dfrac{9}{19}.$

The average score is 3 9/19 points.

The median is 10th term in the data set - 3 points (means the middle score in the data set)

The mode is 3 points (means most happened score)

c) The range of the data is 6-0=6 points.

How many times greater is 8 x 10^-2 than 2x10^-6

umka21 [38]

Answer:

40,000

Step-by-step explanation:

You want to start with the exponent and then multiply afterward in both of the equations.

8 x 10^-2:

10^-2 = 0.01

0.01 x 8 = 0.08

2 x 10^-6:

10^-6 = 0.000001

0.000001 x 2 = 0.000002

Obviously, you can see the relationship between 8 and 2 in the division. Now, you just divide 0.08 by 0.000002 and you get 40,000.

bazaltina [42]

Answer:

<h3>It's answer is D. 11 </h3>

Here we can see there is modulus so

while doing calculation

| -3-8 |

| -11 |

Here it is modulus so - changes into +

so it's answer is 11.
