Answer:
C) [-4,0)
Step-by-step explanation:
Look at the endpoints. You have (-3,0) which isn't included in the function and you have (1,-4) which is included in the function.
We use interval notation when we are describing the subset of numbers in a function by using parentheses to show an endpoint is not included and brackets to show an endpoint is included.
In this case, since we are being asked to find the range of the function, that only pertains to y-coordinates.
Given that (1,-4) is included in the function, this means that y=-4 is included in the function. Therefore the answer's interval notation will start with a bracket to show it's included.
Given that (-3,0) isn't included in the function, this means that y=0 isn't included in the function. Therefore the answer's interval notation will end with a parenthesis to show it's not included.
Combining the two elements, we have an interval notation of [-4,0) which means C is the correct answer
Answer:
<h2><u>
2 miles per hour</u></h2>
Step-by-step explanation:
Speed = Distance / Time
If we measure distance in miles and time in hour, we will get the speed in miles per hour.
Distance = 1 + 2/3 miles, which expressed as an improper fraction is 5/3 miles.
Time = 50 minutes which expressed in hours will be 50/60 or 5/6 hours.
(You can also see that 10 minutes is 1/6 of an hour, hence 50 minutes is 5/6 of an hour)
Speed = Distance / Time
= (5/3) / (5/6)
We know that dividing by "a/b" is same as multiplying by "b/a"
Hence, we have:
Speed = (5/3) * (6/5)
= (5 * 6) / (3 * 5)
= 30 / 15
= 2

Answer:
<em>No, because on the Y row, it has both of the same numbers on that one row. Too make it more simpler, The y row has both 19 on it. Therefore, it is not a function. </em>

Answer:
Step-by-step explanation:
Let the equation be of the form
be the equation, where k=-3 is the horizontal asymptote.
The equation now becomes:
The curve passes through (0,0)
a=3
This implies that:
We again substitute (1,3)
The required equation is
Mendeleev realized that the physical and chemical properties of elements were related to their atomic mass in a 'periodic' way, and arranged them so that groups of elements with similar properties fell into vertical columns in his table.
