Minus 2 degrees every hour
there are 4 hours
d=degrees dropped
- 2 x 4 = d
5+7+11=23
3+11+53=67
3+11+61=71
are some examples
595 - 35t > 420
-35t > 420 - 595
-35t > -175
t < 5........so she can buy 4 tickets
The total length of a boundary defines the perimeter of an equilateral triangle.
<h3>What is the Perimeter of an Equilateral Triangle?</h3>
- The total of the three sides makes up the perimeter of an equilateral triangle.
- The following fundamental characteristics define a triangle as being equilateral:
- The three sides are equal.
- There is a 60° angle between all three.
- The sides of the triangle PQ = QR = RP in the following illustration have equal lengths.
- The triangle's angles are also equal in addition to this. An equilateral triangle is what this is.
- An equilateral triangle's perimeter is now equal to 3a, where a denotes one of the triangle's sides.
- Perimeter of Equilateral Triangle Formula : P = 3a, where 'a' stands for one of the triangle's sides, is a simple formula for calculating an equilateral triangle's perimeter. An equilateral triangle has three equal sides, hence the sum is equal to three equal sides, or 3a.
- Additional equilateral triangle formulas include the following: When we need to determine a triangle's height from its sides, we can apply the following formula: Equilateral Triangle Height = (3a)/2
- The semi-perimeter of an equilateral triangle must be determined in a few situations. Half of a perimeter, or semi-perimeter, is equal to 3a/2, which is derived using the formula semi-perimeter = (a + a + a)/2.

Problem 2
<h3>Answers:</h3><h3>Domain = [-2, 2)</h3><h3>Range = {-2, -1, 0, 1, 2}</h3>
===============================
Explanation:
The domain is the set of allowed x inputs of a function. We see that the left most point is when x = -2, so -2 is the smallest value allowed in the domain. On the opposite side of the spectrum, we see that x = 2 is the right most value. However, x = 2 is not allowed in the domain because of the open hole here. This is why we use a curved parenthesis for this part. Whereas a square bracket for -2 tells the reader "-2 is part of the domain". The answer you wrote down is very close. Just change the second square bracket to a curved parenthesis.
For the range, we simply have 5 possible y value outputs and they are: -2 -1, 0, 1 or 2. No other y values are possible. Since we have so few items in the range, we just list the values and put them between curly braces to indicate we have a set of values. We cannot do this with the domain as there are infinitely many items in the domain (eg: x = 1.27 and x = 2.339 are in the domain).
