Answer:
10 ft x 10 ft
Area = 100 ft^2
Step-by-step explanation:
Let 'S' be the length of the southern boundary fence and 'W' the length of the eastern and western sides of the fence.
The total area is given by:
The cost function is given by:
Replacing that relationship into the Area function and finding its derivate, we can find the value of 'S' for which the area is maximized when the derivate equals zero:
If S=10 then W =20 -10 = 10
Therefore, the largest area enclosed by the fence is:
Answer:
256.
Step-by-step explanation:
Each position can be one of 2 states so the number of possibilities
is 2^8 = 256.
10)So plug in the value of a + 3 into where the x of the equation
r(a+3)= 6 6 *you can simply if you want*
------- ______
(a+3)8 distribute=24 + 8a
11) f(-2)=n whenever you have f with a # inside the parenthesis know that they're giving you the x value so f(x)= and on this side is the y value but on tables y value are titled as f(x). So f(-2) is 3
12)Instead of giving you the x-value they gave you the y value this time "=9?" on the bottom. So you go to the f(x) column and find 9 and the # next to it which is 0
First you have to subtract 4/11 from the variable side of the equation and the right side as well. Then you'll have s=9/22-8/22, so your answer is 1/22
The answer is 12. The digit 2 is 2 times more than 1, so it matches the first part. 12 + 9 = 21. If you switch the digits of 12 around, you will get 21. So the answer is 12.
