Shifting a graph up by c units involves adding c to the whole function
therefor
y=ax^2+c is c units higher than y=ax^2 (aka, it is shifted c units up)
the first choice has a negative 7 and the second choice has a negative 161 these are both negatives in different places which cause a different reaction
The area of the yard is 50,600 square feet.
Option: C.
<u>Step-by-step explanation:</u>
The given information forms a trapezoid.
The AB is the upper base (a) and its length is 200 feet.
The CD is the lower base (b) and its length is 260 feet.
A straight line distance from AB and CD is the height (h) and its measures as 220 feet.
The area of trapezoid A=
.
A=
.
=
.
=230(220).
=50600 
Thus the area of John's yard is 50,600 square feet.
The answer is: 6,641.40$
Explanation:
Six thousand= 6,000
Six hundred= 600
Forty one= 41
Forty cents: .40
Now add all of these together:
6,000
+ 600
+ 41
+ 0.40
Which will give you 6,641.40$
I hope this helps! :)
