Answer:
True
Step-by-step explanation:
In order for a relation (a set of ordered pairs) to be considered a <em>function</em>, every value in the <em>domain</em> (the set of all the first numbers in the pair) is associated with one value in the <em>range</em> (the set of all second numbers in the pair). This is easiest to see visually. Our domain is the set {2, 3, 4, 5} and our range is the set {4, 6, 8, 10}, and we can visualize the ordered pair (2, 4) as an "arrow" starting a 2 in the domain and ending at 4 in the range. When seen this way, a relation is a function if <em>every value in the domain only has one arrow coming out of it</em>. We can see from the attached picture that the ordered pairs in the problem are a function, so this statement is true.
7/98 = 15/x so if you cross multiply and divide you get 15(98) divided by 7 which means x=86.47...
Where is the graph? do you have a pic or website?
Answer:
125 hrs
Step-by-step explanation:
1500-250=10h
simplify
1250=10h
divide both sides by 10
h=125
125 hrs
Answer:
6 or -6
Step-by-step explanation:
The symbol √ is the square root symbol.
The square root of a number is a number that when you multiply it by itself you get the first number.
For example:
The square root of 9 is 3 since 3 times itself, 3 × 3, is 9.
The square root of 9 is also -3 since (-3) × (-3) is 9.
The question is asking for the positive and negative square roots of 36.
What number multiplied by itself is 36?
The answer is 6 since 6 × 6 = 36 and -6 × -6 = 36
Answer: 6 or -6
