<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:

the Y - intercept is (0,2)
Step-by-step explanation:
the Y intercept is where the line crosses the Y axis
the X intercept is where the line crosses the X axis

Step-by-step explanation:
Answer: 2/3 cups a minute
Step-by-step explanation: If Brayden is adding 1/3 cups of flour to the mixture every 1/2 minutes, you double the 1/2 minutes to get one minute and since you doubled the 1/2 minutes you must double the 1/3 getting 2/3 cups a minute.
Since the denominators (bottom of the fraction) are the same, we can subtract the numerators (the top parts) easily.
