Answer:

The answer to your question is Center = (-8, 6)   radius = 7

Step-by-step explanation:

Data

       (x + 8)² + (y - 6)² = 49

Center = ?

radius = ?

Process

1.- Write the standard form of a circle

      (x - h)² + (y - k)² = r²

2.- Compare the equation given with the standard form

The center of a circle = (h, k)

      h = -8    k = 6    r² = 49

                                r = √49

                                r = 7      

3.- Conclusion

Center = (-8, 6)   radius = 7

Work out 1 3/4+ 3 1/2
choli [55]

We can write,

1 3/4 as 7/4 & 3 1/2 as 7/2

So, 7/4 + 7/2 = 21 / 4 in fraction form.

OR 5 1/4 in mixed form.

Which of the following choices lists the correct values of a,h, and k for the function f(x)=5x^2
Tju [1.3M]

Answer:

For a general quadratic equation like:

y = a*x^2 + b*x + c

a is the leading coefficient.

And we define the vertex of this as (h, k)

Where h is:

h = -b/(2*a)

and k is the y-value given when we use x = h.

Now, in this case we have:

f(x) = 5*x^2

We can see that the leading coefficient is 5, then a = 5.

To find the value of h we use:

h = -b/(2*a)

there is no lineal term, thus b = 0, then:

h = -0/(2*5) = -0/10 = 0

and k is given by

f(h) = f(0) = 5*0^2 = 0

then k = 0.

Concluding:

a = 5

h = 0

k = 0
