Answer:

option a.

+  -  \frac{13}{5}

Step-by-step explanation:

25x^2\: - \:169 = 0

25x^2 = 169

{x}^{2}  =  \frac{169}{25}

x =  +  -  \sqrt{ \frac{169}{25} }

x =  +  -  \frac{13}{5}

Calculate the average rate of change for the given function, from x = −3 to x = 7.
emmainna [20.7K]

Answer:

The average rate of change for the given function, from x = −3 to x = 7 will be:

  • Average rate = -5

Step-by-step explanation:

Given the table

x                      f(x)

-3                     50

3                      10

7                       0

As the interval is from x = -3 to x = 7.

so

at x₁ = -3, f(x₁) = 50

at x₂ = 7,  f(x₂) = 0

Using the formula to determine the average rate of change at which the total cost increases will be:

Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]

                       = [0 - 50] / [7-(-3)]

                      = [-50] / [7+3]

                      = -50 / 10

                      = -5

Therefore, the average rate of change for the given function, from x = −3 to x = 7 will be:

  • Average rate = -5

Answer:

29\sqrt{5}

Step-by-step explanation:

11\sqrt{9*5} - 4\sqrt{5}

Take nine out - square root of 9 is 3

= 3 x 11 \sqrt{5} - 4\sqrt{5}

= 33\sqrt{5} - 4\sqrt{5}

= 29\sqrt{5}

can not be simplified any more

Hope that helped!!! k
