Answer: 16 square units
Step-by-step explanation:
let the vertex in quadrant I be (x,y)
then the vertex in quadratnt II is (-x,y)
base of the rectangle = 2x
height of the rectangle = y
Area = xy
= x(12 - x²)
= -x³ + 12x
d(area)/dx = 3x² - 12 = 0 for a maximum of area
3x² = 12
x² = 4
x = ±2
y = 12-4 = 8
So, the largest area = 2 x 8 = 16 square units
Answer:
Something like M=80-(7x4)
Step-by-step explanation:
61/40, or about 2 and a half miles.the exact number is 2.525. hope this helps.
Usually the easiest way to solve this is by using a calculator. Of course only if your teacher allows you too.
This should be the answer.
