Troista Mobile Accessories sells mobile apps on their Web site. If a customer spends on average, $12 per visit and visits the We

Leno4ka [110]

Answer: The required average is $576.

Step-by-step explanation:

Since we have given that

Percent of customers not returning each year = 25%

Average customer lifetime = $\dfrac{1}{0.25}=4\ years$

Percent of margin on the average bill = 60%

Cost per visit = $12

Number of times each year visited = 20 times

So, Average expense by each customer per year = $12\times 20=\$240$

Average margin = 60% of 240 = $0.6\times 240=\$144$

Average non discounted gross profit during a customer's lifetime is given by

$144\times 4=\$576$

Hence, the required average is $576.

Let f={(-1, 4),(1, 9),(4, 0)} and g={(-1, -8),(2, -7),(4, 8),(5, -9)}. Find g/f and state its domain.

tekilochka [14]

Answer:

g/f = {(-1, 2)}

domain of g/f = {-1}

Step-by-step explanation:

Given,

f = {(-1, 4),(1, 9),(4, 0)},

g = {(-1, -8),(2, -7),(4, 8),(5, -9)}

So, Domain of f = {-1, 1, 4},

Domain of g = {-1, 2, 4, 5}

Since,

$\frac{g}{f}(x) = \frac{g(x)}{f(x)}$

Thus, domain of g/f = Domain of f ∩ Domain of g = {-1, 4}

If x = -1,

$\frac{g}{f}(-1) = \frac{g(-1)}{f(-1)}=\frac{-8}{-4}=2$

If x = 4,

$\frac{g}{f}(4) = \frac{g(4)}{f(4)}=\frac{8}{0}=\infty (\text{ not possible})$

Hence, the domain of g/f = {-1}

And, g/f = {(-1, 2)}
