Answer:
x= 81
Step-by-step explanation:
see attached the solution
Since there are 7 days in a week, you divide 200 and 7 to get 28.57.
You must also round to the nearest integer, so the lizards in the shows eat about 29 crickets each day.
Answer: 15
Step-by-step explanation: This is one of those square roots you'll memorize really quickly. You don't even have to simplify it, since it's an integer.
Answer:
C). sign chart; zeroes
Step-by-step explanation:
A function potentially changes sign at each of its <em>zeros</em> and vertical asymptotes. So, to fill out a <em>sign chart</em>, you need to determine what the sign is on either side of each of these points. You can do that using test numbers, or you can do it by understanding the nature of the zero or asymptote.
<u>Examples:</u>
f1(x) = (x -3) . . . . changes sign at the zero x=3. Is positive for x > 3, negative for x < 3.
f2(x) = (x -4)^2 . . . . does not change sign at the zero x=4. It is positive for any x ≠ 4. This will be true for any even-degree binomial factor.
f3(x) = 1/(x+2) . . . . has a vertical asymptote at x=-2. It changes sign there because the denominator changes sign there.
f4(x) = 1/(x+3)^2 . . . . has a vertical asymptote at x=-3. It does not change sign there because the denominator is of even degree and does not change sign there.
