Answer:

<h2>We can feel the effects of the earthquake 50 miles from the epicenter.</h2>

Step-by-step explanation:

The given expression is

x^{2} +y^{2}=2500

Which represents a circumference. So, if this circunference represents the pattern of an earthquare, that means the radius of such circumference represents the miles away from the epicenter.

The given expression is the explicit form of a circumference, like this

x^{2} +y^{2}=r^{2}

Where r is the radius.

So, in this case,

r^{2}=2500\\ r=\sqrt{2500}\\ r=50

Therefore, we can feel the effects of the earthquake 50 miles from the epicenter.

The radius of the circle ( which is the same as the distance from the epicenter) = square root of 2500  which is 50

Answer is 50 miles.

hodyreva [135]

Answer:

The answer to your question is: 16x + 3

Step-by-step explanation:

Step 1 :      f(x) = 8x² + 3x

                f(x +h) =  8(x + h)² + 3( x + h)

                f(x + h) = 8( x² + 2xh + h²) + 3( x + h)

                f (x + h) = 8x² + 16xh + 8h² + 3x + 3h

Step 2 f(x+h) - f(x) =  8x² + 16xh + 8h² + 3x + 3h - ( 8x² + 3x)

                              = 8x² + 16xh + 8h² + 3x + 3h - 8x² -3x

                              = 16xh + 8h² + 3 h

Step 3 f(x + h) - f(x)/ h = h(16x + 8h + 3) /h

                                    = 16x + 8h + 3

Step 4 lim  f(x + h) - f(x)/ h = lim 16x + 8h + 3  = lim 16x + 8(0) + 3 = 16x + 3

        h ⇒0                           h ⇒0                     h ⇒0
