The answer to the first question is 7
Second one is 200-400
Answer: 8 and 9 or -9 and -8
Step-by-step explanation:
Let
be the first of the two integers. Then, since the numbers are consecutive,
is the other integer. We then know that the sum of the squares of
and
is equal to 145. So, now we have the equation

which can be expanded and simplified to

which then gives us the quadratic equation

This can then be factored into

Which can be simplified further into

So either
or
. This gives us two solutions: 8 and 9 or -9 and -8.
Hope this helps! CHEERS!
Answer:

Step-by-step explanation:

To determine the expected number of sales after 3 years of a product, we need an equation that would relate time with the number of sales. In this case, we use the equation above which expresses the number of sales as a function of time. We simply substitute the time which would be 3 years to the equation and evaluate the value of N. We do as follows:
<span> N = 9200 ln (5t + 3)
</span><span> N = 9200 ln (5 ( 3 ) + 3)
</span><span> N = 9200 ln 18
N = 26591.42
Therefore, the correct answer would be option B. The number of sales after 3 years would be about 26591.</span>
