It’s the first one because the parabola is open
-6,-7, and -8, this is more of a guess and check question
Surface area= 24 ft^2
A cube has 6 faces, so the surface area of 1 face would be 24/6, which is 4 ft^2.
The formula for the area of a square is l x w, but in a square both are equal so you're essentially squaring one side.
Therefore, the area of a square ( 4 ft^2 ) can be square-rooted in order to find the length of an edge.
= 2
Therefore, the length of 1 edge of the cube is 2 ft
(I think)
Answer:
Systematic error
Step-by-step explanation:
Assuming that none of the judges are biased, the most likely reason for this difference is the occurrence of systematic errors.
Systematic errors are errors introduced by inaccuracy in the experimental design, be it in the observation or measurement process.
In this case, the reaction time from observing the finish and stopping the clock for each judge might be different, which configures a systematic error.
Answer:
reflected function = (2-x)^2
Step-by-step explanation:
You have the following function:

In order to find the function that is a reflection of f(x), you take into account that a reflection over the y-axis generates a function that is equal to f(-x).
Then, you have:

The reflected function is then (2-x)^2
