The given sequence is
Here the first term, a is 50.
And the difference between two consecutive terms are
So the difference is constant, which is -2. Therefore the sequence is arithmetic .
And the nth term of aritmnetic series is given by
Substituting the values of a and d, we will get
Answer:
Step-by-step explanation:
This question is asking for the function's end behavior. An even degree power function with a negative leading coefficient forms a parabola concave down. This means, its vertex represents the maximum and the parabola opens downward (towards negative infinity).
Thus,
This corresponds with the first answer choice listed:
Answer:
The length and width of the rectangle are 20 feet and 31.25 feet, respectively.
Step-by-step explanation:
Let the scale be and the dimensions of the rectangle being 4 inches and 5 inches, respectively. The scale (), measured in inches per feet, is equivalent to the following rational number:
We can convert each length by dividing it by scale factor. That is:
Length
Width
The length and width of the rectangle are 20 feet and 31.25 feet, respectively.
The one that shows a parabola opening upward or downward.
