The domain is the set of allowed x inputs, or x coordinates of a function. In this case, any point on the curve has an x coordinate that is 4 or smaller.
Therefore, the domain is the set of numbers x such that 
To write this in interval notation, we would write ![(-\infty, 4]](https://tex.z-dn.net/?f=%28-%5Cinfty%2C%204%5D)
This interval starts at negative infinity and stops at 4. We exclude infinity with the curved parenthesis and include 4 with the square bracket.
-----------------------------------------------------------------------
The range is the set of possible y outputs. Every point on this curve has a y coordinate that is either 0 or it is larger than 0.
The range is the set of y values such that 
In interval notation, it would be written as 
This time we start at 0 (including this endpoint) and "stop" at infinity
note: we always use curved parenthesis at positive or negative infinity because we cannot reach either infinity
A . It has a value GREATER than 8
Answer:
Since the balls are drawn with replacement, it means the individual probability remain constant,
I have solved this problem on paper (Figures Attached).
Thanks.
Answer:
if this is a triangle it is 89º
Step-by-step explanation:
because all the angles in a triangle add up to 180
Answer:
40(1.25-t)
Step-by-step explanation:
There are 3 components to consider; time, speed and distance
Time and Speed are given.
The distance has to be calculated.
- Speed to work = 55 miles per hour
- Time to work = 1.25-T
- Speed to home = 40 miles per hour
- Time to home = 1.25-t
- Total Time = T + t = 1.25
<u>Distance for trip to home</u>
Speed = Distance/Time
40 = Total Distance/1.25-t
Total Distance = 40(1.25-t)
<em>Therefore, 40(1.25-t) is the correct answer.</em>
