Answer:
Step-by-step explanation:
This is calculus, but I don't get fractions in the end. To maximize or minimize any function, you need to find the derivative of it, set it equal to 0, then solve for the critical values.
Our given equation is
x + y = 215 and we want to maximize the product, xy. Therefore,
y = 215 - x so its product in terms of x is
x(215-x) which is
. The derivative of this is
215 - 2x. Set it equal to 0 to maximize it.
215 - 2x = 0 so
-2x = -215 and
x = 107.5.
Sub this in to solve for y:
y + 107.5 = 215 and
y = 107.5
The product is 11556.25, not that you need it.
Answer: 5' 10"
Explanation: Borrow a foot from 8 to make it 7 feet and 16 inches. Subtract 6 from 16 to get 10 inches. Subtract 2 from 7 to get 5 feet. So the answer is 5' 10".
That would be f(x) = 4|x|. Reason is, the bigger the number that's multiplied by |x|, the narrower the graph will be. The opposite is true for the smaller the number, & so f(x) = .5|x| will be wider.
Hope this helps!
P= 31
EXPLANATION :opposite sides of a parallelogram are congruent so angles R & S should equal to 180 degrees when you add them and so on for angles Q & T
ANGLES R & S :
2p+3p+25=180
5p+25=180
5p=180-25
5p=155
p=31
ANGLES Q & T
p+87+5p-93=180
6p-6=180
6p=180+6
6p=186
p=31
MATH CHECK:
2(31)+3(31)+25+(31)+87+5(31)-93=360
62+93+25+31+87+155-93=360
453-93=360
360=360
