Natalija [7]

Answer:

C is the correct option.

Step-by-step explanation:

We have been given that

stock XYZ opened at $6.12 and it closed at $6.88 and we have find the rate of change of stock.

Change in the value =| Initial - final |

Change in the value = |6.12-6.88|

Change in the value = 0.76

Hence, the rate of change of stock is given by

$\frac{\text{Change in value}}{\text{initial value}}\times100\\\\=\frac{0.76}{6.12}\times100\\\\=12.4\%$

C is the correct option.

If f(x) = StartFraction x Over 2 EndFraction + 8, what is f(x) when x = 10?

san4es73 [151]

Answer:

Step-by-step explanation:

You are given the function

$f(x)=\dfrac{x}{2}+8$

To find the value of the function f(x) at point x=a, you have to substitute a instead of x into the function expression.

In your case, you have to evaluate f(x) when x=10. Substitute 10 instead of x into the function expression:

$f(10)=\dfrac{10}{2}+8=5+8=13$
