To find this value, simply substitute the number 10 in for x in your equation:

f(x) = x^2 - 2

f(10) = 10^2 - 2 = \boxed{98}

The answer is 98.

Answer:

Job A is more profitable for nearly 49 months (or 50 months including the first month)

Job B is more profitable after 49 months (or 50 months including the first month).

Step-by-step explanation:

Let x be the number of months passed after first month

<u>Job A:</u>

$2,000 for the first month with a $300 raise every month thereafter

Function describing this situation:

f(x)=2,000+300x

<u>Job B:</u>

$1,500 for the first month with a 5% raise every month thereafter

Function describing this situation:

g(x)=1,500\cdot (1+0.05)^x\\ \\g(x)=1,500\cdot 1.05^x

Plot both graphs (see attached diagram). The diagram shows that the job A is more profitable for nearly 49 months (or 50 months including the first month) and the job B is more profitable after 49 months (or 50 months including the first month).

A supermarket has found that 60% of their customers spend more than $75 each visit. Whats the probability that the next 2 custom
spin [16.1K]
Answer: 0.36 or 36%
60%=60/100=0.6

60% is the same as saying 60/100 or 0.6

To solve for the probability of this problem, we have to, multiply the odds of the two separate events together

event1 is a customer that spends more than 75$. The odds of that happening are .6

event 2 is a customer that spends more than 75$. The odds of that happening are .6

probability=event1*event2
probability=.6*.6 
probability=.36 or 36%
