A) The greatest rectangular area will be the area of a square 10 m on each side, 100 m^2.
b) The new dimensions will be 11 m × 11 m.
.. The new area will be (11 m)^2 = 121 m^2.
c) The area was increased by 121 m^2 -100 m^2 = 21 m^2, or 21%.
d) Yes, and no.
.. If you increase the dimensions by 10%, the area will increase by 21%.
.. (40 m)^2 = 1600 m^2
.. (44 m)^2 = 1936 m^2 = 1.21*(1600 m^2), an increase of 21% over the original.
.. If you increase the dimensions by 1 unit, the area will increase by (2x+1) square units, where x is the side of the original. For x≠10, this is not 21 square units.
.. (41 m)^2 = 1681 m^2 = 1600 m^2 +(2*40 +1) m^2 = 1600 m^2 +81 m^2
Answer:
A - 5
Step-by-step explanation:
1 mile in the morning + 1 mile in the afternoon = 2 miles per day
10 miles / 2 miles = 5
Answer:
Step-by-step explanation:
(x-3)(x-3)(x²)(x+2)
(x²-6x+9)(x³+2x²)
x^5+2x^4-6x^4-12x^3+9x^3+18x^2
x^5 - 4x^4 - 3x^3 +18x^2
Substitute 2 into x in the equation so f(x)= 5x2 -12 = -2 so it’s C = -2
