Answer: There are no solutions.
Step-by-step explanation:
≥The solution of an inequality is an interval, i.e. a range.
To prove that the interval found as solution, you must consider several cases.
1) In the case that the ineguailty is ≥ or ≤, first use the limits of the interval to prove they are valid solutions. This is, replace the limit values, one at a time, and verifiy the inequality.
2) If the sign is ≥ or > use a value to the right of the limit value to show that the values to the right are solution, and use a value to the left to show that they are not solution.
3) If the sign is ≤ or <, use a value to the left of the limit value to show that it is a solution and a value to the right of the limit value to show that it is not a solution.
Answer: 480 cu. cm
Step-by-step explanation:
Height of first cylinder: h = V/pi r^
= 9.55 cm
Volume of second cylinder = pi r^2 h
= 480
Answer:
<h2>4</h2>
Step-by-step explanation:
From first piece -6 < x ≤ 0.
From second piece 0 < x ≤ 4.
Therefore -6 < x ≤ 4 → x ∈ (-6, 4]
-7 ∉ (-6, 4]
-6 ∉ (-6, 4]
4 ∈ (-6, 4]
5 ∉ (-6, 4]
