<span>let 2x be the length of rectangw where x is value of x of point on parabola width is represented as y is the length.
Area = 2x*y = 2x (5-x^2) = 10x -2x^3
maximize Area by finding x value where derivative is zero
dA/dx = 10 -6x^2 = 0
--> x = sqrt(5/3)
optimal dimensions: length = 2sqrt(5/3) width = 10/3</span>
Answer:
1129/200 = 5.645
Step-by-step explanation:
31/8 ÷ (x-4 1/4)=17/18 +1 5/6=17/18 +11/6=17/18 +33/18=(17+33)/18=50/18=25/9
31/8 ÷ (x-4 1/4)=25/9
x-4 1/4 = 31/8 ÷25/9 = 31/8 × 9/25 = 279/200
x = 4 1/4 + 279/200 = 17/4 + 279/200 = 850/200 + 279/200 = 1129/200 = 5.645

D) starting amount in his savings account.
in the linear equation the y intercept is the starting point when x is zero, that means that at the starting balance he had 1000 in the bank.
Using proportions, it is found that 7% of the population has blue eyes without blonde hair.
10% of the population has blue eyes. These 10% are composed by:
- 75% of 4%(have blonde hair).
- x% of 96%(do not have blonde hair)
Hence, the relation according to the proportion of 10% is:



Out of the entire population:
0.0729(0.96) = 0.07
7% of the population has blue eyes without blonde hair.
