Answer:

-4

Step-by-step explanation:

The average rate of change of the interval [a,b] is (f(b)−f(a)) / (b−a)

Replacing a=−5, b=4, f(x)=−x^2−5x+12.

(f(b)−f(a))/(b−a) =12−5x4− 4^2 − (12−5 x(−5)−(−5)^2)/ (4−(−5))= −4.

For this case we have that by definition of power properties it is fulfilled that:

$(a ^ n) ^ m = a ^ {n * m}$

We must rewrite the following function:

$f (x) = 7 (\frac {1} {2})^{3x}}$

Using the mentioned property we have:

$f (x) = 7 ((\frac {1} {2}) ^ 3) ^ x$

Solving the operation within the parenthesis we have:

$f (x) = 7 (\frac {1 ^ 3} {2 ^ 3}) ^{ x}\\f (x) = 7 (\frac {1} {8})^{x}$

Thus, the correct option is option B

madreJ [45]

Answer:

Step-by-step explanation:

Step one:

given data

we are given that the linear function for the cost is c=3.5t

c is the cost and

t is the number of tickets.

We are told that t=15, to find c, let us put the value of t in the linear function for the cost

$c=3.5(15)\\\\c=52.5$

<u>This shows that 15 tickets will cost $52.5</u>
