What is the average rate of change for this exponential function for the interval from x = 2 to x = 4?
Hunter-Best [27]

Answer:

The average rate of change over the interval is 120

Step-by-step explanation:

For a function f(x) the average rate of change over an interval [a,b] is given as;

f(b)-f(a)/b-a

in this case, a is 2 and b is 4

f(b) is 256 and f(a) is 16

Substituting these values in the equation for rate of change, we have;

(256-16)/(4-2) = 240/2 = 120

The states C and D spend a total of ​$54.6 million for tourism. The state C spends ​$2 million more than the state D. Find the a
Roman55 [17]

State C spent $28.3 million and State D spent $26.3 million.

Step-by-step explanation:

Total spent for tourism = $54.6 million

Let,

The amount spent by State C = x

The amount spent by State D = y

According to given statement;

x+y = 54.6    Eqn 1

x=y+2    Eqn 2

Putting value of x from Eqn 2 in Eqn 1

(y+2)+y-54.6\\y+2+y=54.6\\2y=54.6-2\\2y=52.6\\

Dividing both sides by 2

\frac{2y}{2}=\frac{52.6}{2}\\y=26.3

Putting y=26.3 in Eqn 2

x=26.3+2\\x=28.3\\

State C spent $28.3 million and State D spent $26.3 million.
