To the nearest square foot is the same as to the nearest whole number. That would be 63.
Desmos graphing calculator will draw this graph for you.
draw 2 curves
y = x^4 + x^3
and
y = 4x^2 + 4x
The roots are the points where the 2 curves intersect.
You can see by simple substitution that one root is zero.
x^4 + x^3 - 4x^2 - 4x = 0
f(2) = 16 + 8 - 4(4) - 4(2) = 0 so 2 is another root
f(-2) = 16 - 8 - 16 + 8 = 0 so -2 is another root
f(-1) = 1 - 1 - 4 + 4 = 0 so -1 is the other root
The answer is A
Answer:
18x^3+8x^2
Ya know you don't have to post the same question three times
Answer:
decreasing, non-increasing
Step-by-step explanation:
The sequence is ...
1, 1/2, 1/3, 1/4, ...
Each term is smaller than the one before it, so the sequence is decreasing (also, non-increasing).
Answer:
The result is <u>10.42 kilometers, or 10,420 meters or 1'042,000 centimeters.</u>
Step-by-step explanation:
1. Let's review the information given to us for solving the question:
8 kilometers plus 2,300 meters plus 12,000 centimeters
2. Let's do the conversions to find the result either in kilometers, meters or even centimeters.
A. In kilometers:
8 kilometers
2,300 meters = 2.3 kilometers
12,000 centimeters = 120 meters = 0.12 kilometers
<u>10.42 kilometers</u>
B. In meters
8 kilometers = 8,000 meters
2,300 meters
12,000 centimeters = 120 meters
<u>10,420 meters</u>
<u>C. In centimeters</u>
8 kilometers = 8,000 meters = 800,000 centimeters
2,300 meters = 230,000 centimeters
12,000 centimeters
<u>1'042,000 centimeters</u>
