I hope the choices for the numerators of the solutions are given.

I am showing the complete work to find the solutions of this equation , it will help you to find an answer of your question based on this solution.

The standard form of a quadratic equation is :

ax² + bx + c = 0

And the quadratic formula is:

x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}

So, first step is to compare the given equation with the above equation to get the value of a, b and c.

So, a = 10, b = -19 and c = 6.

Next step is to plug in these values in the above formula. Therefore,

So,

So,

Hope this helps you!

Consider all seven-digit numbers that can be created from the digits 0-9 where the first and last digits must be odd and no digi
Yuliya22 [10]

Answer:

1/4 or 0.25

Step-by-step explanation:

The total possibilities of any 7 digit number using 0-9 is :

9×10×10×10×10×10×10=9000000

To work out the total possibilities in this question :

We look at the conditions :

The first digit can only be 5 numbers :

1 , 3 , 5 , 7 , 9

Now we subtract 5 from 9 :

9-5 = 4

Since no repeats for 2 , 3 , 4, 5, 6:

9 , 8 , 7 , 6 , 5,  

5 possibilities for the last digit :

Total possibilities for this code :

4 × 9 × 8 × 7 × 6 × 5 × 5 = 302400

If it begins with 5 that is only 1 possibility for the first digit

1 × 9 × 8 × 7 × 6 × 5 × 5 = 75600

Now we make a fraction :

75600÷302400

Dividing top and bottom by 75600 gives you 1/4 or 0.25

Hope this helped and have a good day

I need answer please​
Assoli18 [71]

It is centered at (h,k) --> (0,0) and has a radius 9

The equation of the circle is

           (x-h)^{2} +(y-k)^{2} =r^{2} \\(x-0)^{2} +(y-0)^{2} =r^{2}\\x^{2} +y^{2} = 9^{2}

Hope that helps!

B) The perimeter of the shape is 25.71 cm
natita [175]

Answer:

r=4cm

Step-by-step explanation:

Having the radius to be involved, the shape is a circle.

<u>Circumference formula </u>

c=2\pi r

Finding radius, formula will be reversed.

r=\frac{25.72cm}{2\pi }

r=\frac{25.71cm}{2(3.142)}            r=\frac{25.71cm}{6.284}          r=4.09cm
