<span>Answer:
let x = shortest base of the trapezoid
A = h (x/2 + r) = âš(r² - (x/2)²) (r + x/2)
= âš(1 - (x/2)²) (1 + x/2) .... if r = 1
dA/dx = (2 - x - x²) / (2âš(4 - x²))
= 0 at x = 1 .... which is a relative maximum because d²A/dx² < 0
A = (3/4) âš3</span>

Answer:
-12.5°C
Step-by-step explanation:
To solve this problem you would multiply -2.5 by 5.

Today's low temperature is -12.5°C.
Answer: lower bound = 9550
<u>Step-by-step explanation:</u>
Since the number is rounded to the nearest hundred, the actual value is somewhere between 9550 (which rounds up to 9600) and 9649 (which rounds down to 9600).
The lower bound is: 9550
The upper bound is: 9649
